Posterior Staphyloma

Posterior staphyloma is a bulging “out-pouching” of the back wall of the eye because the white coat of the eye (the sclera) becomes thin and stretches, usually in people with long, highly myopic eyes. This changes the eye’s shape, stresses the retina and choroid inside, and can slowly reduce vision over time. Myopia Institute –EyeWiki

Posterior staphyloma means the back wall of the eye bulges outward like a small “pouch.” It usually happens in high or pathologic myopia (very nearsighted eyes) where the white coat (sclera) at the back of the eye has become thin and weak over time. This stretching can also thin and stress the retina and choroid (the light-sensing layer and its blood supply). The bulge changes the eye’s shape, can worsen vision, and raises the risk of problems such as myopic macular degeneration, choroidal neovascularization (new leaky blood vessels), foveoschisis (retinal splitting), and retinal detachment.

Think of the eye as a ball made of strong fabric. In some people, the back of that ball becomes weak. When that happens, the wall at the very back starts to bow outward like a dent flipped inside-out. Doctors call this outward bow a “posterior staphyloma.” The bulge is not just on the surface. The inner layers—the retina (the light-sensing film), the choroid (the blood layer), and the vitreous (the gel)—now have to drape over a steeper curve. That new curve can stretch and thin the tissues, make the retina sag or split in places, and change how light is focused on the macula (the sharp-vision center). Over years, this can cause blurry vision, wavy lines, gray spots, or trouble seeing details, especially if other problems like myopic traction, macular holes, or new weak blood vessels (myopic CNV) also appear. In modern eye care, imaging like OCT and 3D scans lets doctors “map” the exact shape of this bulge to guide monitoring and treatment choices. PMCScienceDirectIOVS

How doctors classify posterior staphyloma

Classic (Curtin) classification—10 shapes seen at the back of the eye.

Before wide-field scans existed, doctors looked at the back of the eye and grouped staphylomas by where they sat and how they looked. Curtin described ten types: five “primary” types (I–V) around the posterior pole, macula, peripapillary, nasal, and inferior areas, and five “combined” types (VI–X), which are mixes of the primary types. This older system is still widely quoted and helps clinicians describe what they see. EyeWikiPentaVisionScienceDirect

Modern (Ohno-Matsui) classification—based on 3D eye shape.

With three-dimensional MRI and wide-field imaging, a simpler, location-based scheme is now common: wide macular, narrow macular, peripapillary, nasal, inferior, and other patterns. In many series, wide macular staphyloma is the most frequent. This imaging-based approach matches what scans actually measure and is practical for follow-up. PubMedScienceDirectPMC

Types

The “type” tells you where the back wall has bulged and how broad the bulge is. Below are the common modern types, followed by the classic Curtin types so you can map older notes to newer imaging.

A. Modern, imaging-based types

1. Wide macular staphyloma
   The bulge is broad and centered on the macula. The curve is shallow but wide, so a big area of the central retina rides over a dome-shaped hollow. This type is common and ties closely to central vision changes because the macula sits on the steepest part of the curve. PubMedScienceDirect

2. Narrow macular staphyloma
   The bulge is still at the macula but is tighter and more confined. Because it is narrow, the transition from normal wall to bulge is sharper, which can increase local stress on the fovea and the surrounding retina. PubMed

3. Peripapillary staphyloma
   The bulge surrounds the optic disc. The nerve head and nearby retina sit in a well. This can change the appearance of the nerve and can complicate judging the optic disc for glaucoma because the shape is abnormal to begin with. PubMed

4. Nasal staphyloma
   The bulge is on the side of the nose (nasal fundus). People may not notice early symptoms because the macula can be spared at first, but distortion and field defects can still occur as the curve deepens. PubMed

5. Inferior staphyloma
   The bulge sits below the optic disc and macula. Gravity and traction from the vitreous may worsen fluid pockets or schisis in the lower macula in some eyes. PubMed

6. Other patterns
   Some eyes show mixed or atypical shapes that do not fit neatly into the five groups above. These are labeled “other,” but the care plan still follows the same logic: map the curve, watch the macula, and manage traction or neovascular changes if they appear. PubMed

B. Classic (Curtin) types (to understand older reports)

• Type I: Primary, posterior pole

• Type II: Primary, macular area

• Type III: Primary, around the optic disc (peripapillary)

• Type IV: Primary, nasal to the disc

• Type V: Primary, below the disc (inferior)

• Types VI–X: Combined patterns (mixes of the above, including tiered, septal, and plicated forms)

These labels come from ophthalmoscopic drawings and still appear in charts and studies, especially when comparing “simple” (I–V) versus “complex” (VI–X) staphylomas. EyeWikitvst.arvojournals.org

Causes and risk factors

Posterior staphyloma is usually the end result of long-term eye elongation (axial myopia) combined with weak scleral tissue. Below are causes and drivers that, alone or together, make the back wall bow outward.

1. Excessive axial elongation
   A longer eyeball stretches the back coat, making the sclera thinner and more likely to bulge. This is the main driver in pathologic myopia. Myopia Institute –

2. Early-onset, fast-progressing myopia
   Myopia that starts young and grows quickly gives more years of stretch on the sclera, raising the chance of later staphyloma. Myopia Institute –

3. Genetic tendency to high myopia
   Family history of high myopia is a strong risk. Genes that influence eye growth and scleral structure make elongation and wall thinning more likely. Myopia Institute –

4. Ethnic background
   Some populations (for example, many East Asian groups) have higher rates of pathologic myopia and thus more posterior staphyloma. Myopia Institute –

5. Less time outdoors in childhood
   Low outdoor time is linked to faster myopia progression, which over years can contribute to staphyloma risk through more axial growth. Myopia Institute –

6. High near-work load
   Heavy reading or screen time does not directly “cause” the bulge but is linked to myopia progression, which increases the chance of staphyloma later. Myopia Institute –

7. Scleral remodeling and thinning with age
   With time, long eyes show biochemical changes in the sclera that make it more plastic and thin, so the posterior wall yields to the inner pressure and bows. NCBI

8. Weak collagen in the sclera
   Connective-tissue disorders (like Marfan or some Ehlers–Danlos types) may weaken scleral collagen, lowering resistance to stretch and predisposing to bulge. (Mechanism supported by connective-tissue literature; approach to staphyloma remains imaging-led.) NCBI

9. Myopic maculopathy and chorioretinal atrophy
   Loss of choroid and retina at the back of long eyes removes “internal bracing,” making the wall more prone to bow. PubMed

10. Myopic traction maculopathy (foveoschisis)
    An elongated eye plus sticky vitreous can pull on a fragile macula that sits over a curved wall; traction can deepen the local hollow over time. PubMed

11. Peripapillary tissue changes
    Thinning and tilt around the optic nerve in long eyes alter local biomechanics and can encourage a peripapillary bulge. PubMed

12. Posterior scleritis or chronic inflammation
    Inflammation that thins the sclera can cause or worsen a localized outpouching at the posterior pole even in non-high-myopic eyes. (Less common but recognized pathway.) NCBI

13. Prior ocular trauma
    Blunt injury can damage scleral fibers. In a long eye with thin walls, this may later form a weak spot that bows. (Uncommon, but reported in case literature.)

14. After eye surgery in already thin sclera
    Most retinal surgeries do not cause staphyloma, but in an eye with very thin sclera, wound sites or structural changes might unmask a bulge later. (Uncommon; clinicians monitor long eyes closely after surgery.)

15. Axial length >26.5 mm
    Very long axial length is a practical marker of risk; it signals that the wall has been under long-term stretch and is vulnerable. EyeWiki

16. Older age in high myopia
    More years lived with a long globe increases the chance the posterior wall will eventually yield into a staphyloma. PMC

17. Eyes without high myopia but with local scleral weakness
    Though uncommon, staphyloma can occur even when the refractive error is not very high if the posterior sclera is focally weak. PubMed

18. Tilted disc and torsion
    A very oblique nerve head may redistribute stress at the posterior pole and associate with local outpouching in long eyes.

19. Persistent vitreomacular adhesion in a long eye
    If the vitreous stays attached in an area that lies over a steep curve, chronic micro-pull can contribute to local sagging.

20. General biomechanical mismatch
    In very long eyes, the inner layers (retina/choroid) cannot “keep up” with scleral expansion, so the whole pole remodels into a bulge with thinned, stretched tissues. NCBI

Symptoms

Symptoms vary. Some people have no symptoms at first and the staphyloma is found on imaging. Others notice central vision changes, especially if the macula sits on the bulge.

1. Slowly worsening distance blur even with glasses or contacts, because the macula sits on a new curve that blurs detail.

2. Lines look wavy or bent (metamorphopsia) when reading a grid or tiled floor—often a sign the macula is stressed.

3. A gray spot or missing patch in the center (central scotoma) when the macula is involved.

4. Micropsia (letters look smaller than they should) because the retina is stretched over a deeper curve.

5. Patchy blind spots off-center if the bulge and thinning sit away from the fovea.

6. Difficulty with fine print even with a fresh prescription.

7. Needing more light to read comfortably.

8. Colors look duller if the macula and photoreceptors are thinned.

9. Visual fatigue and eye strain after near tasks due to unstable focus and distorted images.

10. Sudden new distortion or blur if a complication appears, like myopic choroidal neovascularization.

11. Floaters from changes in the vitreous, which are common in long eyes.

12. Glare and halos if the retina struggles with contrast on a curved surface.

13. Trouble with night vision because thin retina and choroid can reduce low-light sensitivity.

14. Headaches from visual effort as the brain struggles to merge distorted images.

15. No symptoms at all in early or off-center bulges—found only during a dilated exam with imaging.

Diagnostic tests

Doctors start with a history and eye exam, then move to imaging that measures the eye’s shape. Imaging is central because the diagnosis depends on showing the posterior wall is bowed relative to the surrounding eye.

A) Physical exam (at the slit lamp and in the clinic)

1. Best-corrected visual acuity
   Tells how much detail you can see with the right prescription. Declines over time can hint that the macula is riding a deeper curve or has new damage.

2. Pupil reactions and anterior segment check
   Rules out other causes of blur or pain and prepares for dilation to see the back of the eye safely.

3. Dilated fundus examination
   With bright lenses and a dilated pupil, the doctor directly inspects the posterior pole. Clues include a pale, thinned appearance, tessellated fundus, lacquer cracks, or a sharp border where the wall curves. This step guides which imaging to run next. EyeWiki

B) Manual/psychophysical tests (you respond during the test)

4. Refraction and retinoscopy
   Finds the exact glasses power. Very high minus power suggests a long eye; differences between refraction and vision quality can imply macular issues over a curved wall.

5. Amsler grid
   A simple square grid you look at with one eye. Wavy lines or missing boxes suggest macular distortion over the staphyloma.

6. Automated visual field testing
   Maps blind spots and sensitivity. Bowing near the optic disc or nasal/inferior bulges can create field defects that match the bulge location.

7. Microperimetry
   Checks sensitivity point-by-point at the macula while tracking eye movements. Helpful to document function over time in eyes with central bulges.

C) Lab and pathological tests (used selectively)

8. Basic systemic labs if inflammation suspected
   If pain, redness, or uveitis signs exist, doctors may check markers (like ESR/CRP or autoimmune screens) to look for posterior scleritis or systemic inflammation that can thin sclera.

9. Genetic or connective-tissue screening when indicated
   Rarely, features suggest a collagen disorder. Appropriate testing helps guide counseling and monitoring if scleral weakness is systemic.

10. Ocular fluids or infectious work-up (rare)
    If an inflammatory or infectious cause is suspected, targeted testing may be done; this is not routine for typical myopic staphyloma.

D) Electrodiagnostic tests (measure the retina/nerve’s electrical signals)

11. Full-field ERG (electroretinogram)
    Assesses overall retinal function. Long, thinned eyes can show reduced responses; this helps separate retinal disease from purely optical blur.

12. Multifocal ERG
    Measures the macula’s electrical output in small zones. Decreased macular responses can match areas draped over the bulge.

13. Pattern ERG
    Focuses on ganglion cell function and can help if peripapillary changes confuse the picture.

14. Visual evoked potentials (VEP)
    Checks the pathway from eye to brain. Helpful if optic nerve involvement around a peripapillary staphyloma is suspected.

E) Imaging tests (the core of diagnosis and follow-up)

15. Optical coherence tomography (OCT)
    Cross-section “slices” of the macula and posterior pole show the retina draped over a curved wall, plus complications like foveoschisis, macular hole, or subretinal fluid. Swept-source and wide-field OCT can capture more of the bulge in a single map. ScienceDirectIOVS

16. Ultra-widefield OCT (UWF-OCT)
    Newer systems stitch multiple lines to reconstruct the 3D shape of the posterior pole, allowing doctors to measure staphyloma depth and width across a very wide view. IOVS

17. 3D magnetic resonance imaging (3D-MRI) of the globe
    Provides a full 3D shape of the eye and was key to the modern classification (wide macular, narrow macular, etc.). It is not done in every clinic but is very informative for research or complex cases. PubMed

18. B-scan ocular ultrasound
    Shows the contour of the back wall even if the media is cloudy (for example, with a dense cataract). A posterior staphyloma appears as a localized posterior outpouching.

19. Optical biometry (axial length measurement)
    Measures eye length to 0.01 mm. A long axial length supports the diagnosis and helps monitor progression over the years. EyeWiki

20. Fundus photography and wide-field imaging; angiography when needed
    Color photos document borders and atrophy. Fundus autofluorescence (FAF) maps RPE stress. Fluorescein and indocyanine green angiography help detect myopic CNV. OCT-angiography (non-invasive) shows flow in chorioretinal layers and helps guide treatment if new vessels appear. ScienceDirect

Non-pharmacological treatments

Remember: These do not “shrink” the bulge. They protect vision, slow myopia in children, and reduce complication risk.

1. Education & self-monitoring
   Purpose: Help you recognize warning signs early.
   Mechanism: Using an Amsler grid weekly and noting new distortion leads to prompt care for CNV or traction.

2. High-index aspheric spectacles
   Purpose: Lighter, thinner lenses reduce image distortion at the edges.
   Mechanism: Aspheric design lessens aberrations in high myopia, improving comfort and clarity.

3. Rigid gas-permeable (RGP) contacts
   Purpose: Sharper optics than soft lenses for some high myopes.
   Mechanism: A rigid front surface neutralizes corneal irregularity for crisper focus.

4. Modern scleral contact lenses
   Purpose: Excellent optics and comfort for very high prescriptions or irregular corneas.
   Mechanism: A fluid reservoir under the lens creates a smooth optical surface.

5. Orthokeratology (night lenses) for children/teens
   Purpose: Slow myopia progression during growth years.
   Mechanism: Overnight corneal reshaping reduces daytime prescription and signals the eye to slow axial elongation.

6. Myopia-control spectacle designs (e.g., DIMS-type)
   Purpose: Slow progression in kids who don’t use contacts.
   Mechanism: Special lens zones change retinal image profile to reduce growth signals.

7. Outdoor time routine (goal: ~2 hours/day in daylight)
   Purpose: Reduce myopia onset and speed in children.
   Mechanism: Bright outdoor light and long-distance viewing influence retinal dopamine and growth signals.

8. Near-work hygiene (20-20-20 rule)
   Purpose: Reduce eyestrain and possibly myopia drivers.
   Mechanism: Every 20 minutes, look 20 feet away for 20 seconds; prevents sustained accommodative stress.

9. Reading distance & posture (≥35–40 cm, elbows-distance)
   Purpose: Avoid “nose-to-book” viewing that stresses the system.
   Mechanism: Larger working distance reduces retinal defocus signals driving axial growth in kids.

10. Lighting optimization
    Purpose: Reduce glare and boost contrast for reading.
    Mechanism: Bright, even, warm lighting with task lamps improves macular performance.

11. Low-vision rehabilitation
    Purpose: Teach skills to use remaining vision efficiently.
    Mechanism: Eccentric viewing training and device use maximize functional sight.

12. Magnification tools (hand, stand, electronic)
    Purpose: Make text and objects easier to see.
    Mechanism: Magnification + high contrast compensate for macular detail loss.

13. Device accessibility settings
    Purpose: Reduce daily frustration.
    Mechanism: Larger fonts, bold text, dark mode, voice-to-text ease visual demand.

14. Fall-prevention home changes
    Purpose: Safety if peripheral vision or contrast is poor.
    Mechanism: Night lights, high-contrast stair edges, no loose rugs prevent injuries.

15. UV-blocking sunglasses & hats
    Purpose: Comfort and possible protection of fragile tissues.
    Mechanism: Cuts glare and UV exposure that aggravate light sensitivity.

16. Dry-eye self-care
    Purpose: Improve comfort and visual stability for long reading.
    Mechanism: Blink breaks, humidifier, warm compress stabilize the tear film.

17. Sleep hygiene
    Purpose: Better daytime visual function.
    Mechanism: Adequate sleep improves contrast sensitivity, attention, and comfort.

18. Smoking cessation (behavioral support)
    Purpose: Protect micro-circulation and collagen.
    Mechanism: Quitting smoking reduces oxidative stress that damages retinal tissues.

19. Healthy Mediterranean-style eating pattern
    Purpose: Support vascular and collagen health.
    Mechanism: Fruits/veg, fish, nuts, whole grains supply antioxidants and omega-3s.

20. Regular follow-ups (personalized schedule)
    Purpose: Catch CNV, traction, or detachment early.
    Mechanism: Periodic OCT and exam detect small changes before vision is lost.

Drug treatments

Important: No medicine reverses a staphyloma itself. Drugs treat complications, especially myopic choroidal neovascularization (mCNV) or macular swelling. Always follow your retina specialist’s plan.

1. Ranibizumab (anti-VEGF)
   Class: Anti-VEGF biologic (injection into the eye).
   Dose/Timing: 0.5 mg/0.05 mL intravitreal, typically 1 injection, then PRN (as needed) based on OCT/vision.
   Purpose: Close and dry mCNV to protect central vision.
   Mechanism: Blocks VEGF so new leaky vessels shrink and stop leaking.
   Side effects: Temporary irritation, pressure rise, floaters; rare infection (endophthalmitis) or retinal tear/detachment—urgent if severe pain/vision drop.

2. Aflibercept (anti-VEGF)
   Class: Anti-VEGF/VEGF-trap.
   Dose/Timing: 2 mg/0.05 mL intravitreal; usually single injection then PRN for mCNV.
   Purpose/Mechanism: Same goal as ranibizumab with high VEGF binding.
   Side effects: Similar to ranibizumab.

3. Bevacizumab (anti-VEGF, off-label)
   Class: Anti-VEGF monoclonal antibody.
   Dose/Timing: 1.25 mg/0.05 mL intravitreal, PRN.
   Purpose: Cost-effective mCNV control where appropriate.
   Mechanism/Side effects: VEGF blockade; same risk profile; off-label use is common but guided by your doctor.

4. Conbercept (anti-VEGF; regional availability)
   Class: Anti-VEGF fusion protein (used in some countries).
   Dose/Timing: 0.5 mg/0.05 mL intravitreal, PRN.
   Purpose/Mechanism/Side effects: As above; availability varies by region.

5. Verteporfin (for photodynamic therapy, PDT)
   Class: Photosensitizing drug used with a special laser.
   Dose/Timing: 6 mg/m² IV over ~10 min, then 689-nm laser to the CNV per protocol.
   Purpose: Option when anti-VEGF is not suitable; used far less today.
   Mechanism: Light activates verteporfin in CNV, generating reactive oxygen species that close abnormal vessels.
   Side effects: Photosensitivity for 48 hours (avoid sunlight), infusion-site pain/back pain.

6. Low-dose atropine eye drops (for myopia control in children)
   Class: Muscarinic antagonist (cycloplegic).
   Dose/Timing: 0.01–0.05%, 1 drop nightly in each eye (multi-year program).
   Purpose: Slow the speed of myopia progression to reduce lifetime risk of staphyloma and its complications.
   Mechanism: Retinal/scleral signaling changes that slow axial elongation.
   Side effects: Mild light sensitivity/near blur at higher doses; rare allergy.

7. Topical dorzolamide 2% (select macular edema cases, off-label)
   Class: Carbonic anhydrase inhibitor (drop).
   Dose/Timing: 1 drop three times daily to the affected eye.
   Purpose: Reduce mild cystoid macular edema when present.
   Mechanism: Alters retinal fluid transport to reduce swelling.
   Side effects: Bitter taste, stinging; avoid if sulfa allergy.

8. Acetazolamide (oral)
   Class: Carbonic anhydrase inhibitor (tablet).
   Dose/Timing: 250 mg 2–3 times daily, short courses only, if your specialist advises.
   Purpose: Additional swelling control in select scenarios.
   Mechanism: Fluid shift from retina/choroid.
   Side effects: Tingling, frequent urination, fatigue, kidney stone risk; avoid in sulfa allergy/pregnancy unless specialist directs.

9. Triamcinolone acetonide (intravitreal steroid, selective)
   Class: Corticosteroid (injection into the eye).
   Dose/Timing: 2–4 mg intravitreal, case-by-case.
   Purpose: Control inflammation or edema not responding to other care.
   Mechanism: Strong anti-inflammatory effect reduces vascular leak.
   Side effects: Intraocular pressure rise, cataract acceleration, infection risk.

10. Prednisolone acetate 1% eye drops (only if active inflammation)
    Class: Topical steroid.
    Dose/Timing: Often 4×/day then taper, guided by your doctor.
    Purpose: Calm posterior segment inflammation if that is present.
    Mechanism: Blocks inflammatory pathways.
    Side effects: Pressure rise, cataract over time—monitor closely.

Doses and schedules are examples; your retina specialist will individualize based on imaging and response.

Dietary molecular supplements

Honest note: Supplements do not repair a staphyloma. They may support retinal metabolism and overall eye health. Evidence in degenerative/pathologic myopia is mixed. Discuss with your clinician, especially if pregnant, anticoagulated, or with kidney stones.

1. Lutein 10 mg/day – macular pigment antioxidant; may improve contrast/visual comfort by filtering blue light.

2. Zeaxanthin 2 mg/day – partners with lutein in macula; free-radical scavenger.

3. Omega-3 (EPA+DHA) ~1 g/day – supports retinal membranes and tear film stability.

4. Vitamin C 500 mg/day – collagen and antioxidant support for scleral/retinal tissues.

5. Vitamin E 200–400 IU/day – lipid antioxidant; supports photoreceptor membranes.

6. Zinc 25–40 mg/day + Copper 2 mg/day – cofactors in retinal enzymes; avoid excess to protect gut/kidney.

7. Astaxanthin 6–12 mg/day – potent antioxidant; may help asthenopia (eye fatigue).

8. Anthocyanins (bilberry) 80–160 mg/day – flavonoids that may aid night contrast; don’t mix with strong anticoagulants without advice.

9. Coenzyme Q10 100–200 mg/day – mitochondrial support for neuronal energy.

10. Vitamin D3 1000–2000 IU/day – general anti-inflammatory tone; maintain sufficiency (check levels).

Regenerative / “hard” immunity / stem-cell-style options

Straight talk: There are no approved stem-cell drugs or immune “boosters” that treat posterior staphyloma. Below are research-stage or niche concepts your specialist may discuss only in trials or specialized centers.

1. 7-Methylxanthine (7-MX) oral therapy (investigational)
   Function: A xanthine derivative studied to slow axial elongation in children.
   Dose studied: ~400–1200 mg/day, divided (protocol-dependent).
   Mechanism: May influence scleral collagen remodeling signals.
   Status: Not widely approved; clinical trials/limited regions.

2. Posterior scleral cross-linking (experimental)
   Function: Aim to stiffen scleral collagen chemically or with light.
   Agents: Riboflavin/blue-light, genipin, others under study.
   Mechanism: New cross-links between collagen fibers reduce stretch.
   Status: Research/early clinical experiences; not standard of care.

3. Posterior scleral reinforcement materials (biologic/biomaterial advances)
   Function: Combine surgery with new graft materials for better integration.
   Mechanism: Mechanical support + potential bioactive scaffolds.
   Status: Evolving; outcomes vary by center and indication.

4. RPE/retinal cell therapies (iPSC/ESC-derived) — trial stage
   Function: Replace/support damaged cells in advanced maculopathy.
   Mechanism: Cell replacement or paracrine support to improve function.
   Status: Early trials in other macular diseases; experimental for myopic maculopathy.

5. Suprachoroidal drug delivery platforms
   Function: Place medicines near the choroid with less systemic exposure.
   Mechanism: Targeted delivery to thin choroid; may help future therapies.
   Status: Platform under development; not a cure itself.

6. Rho-kinase pathway modulators (preclinical/early use)
   Function: Potential influence on scleral ECM remodeling.
   Mechanism: Cytoskeletal/ECM signaling changes may stabilize structure.
   Status: Investigational; not routine for staphyloma.

Surgical and procedural options

Surgery targets complications of staphyloma (traction, macular splitting, CNV, detachment) or aims to reinforce the posterior wall.

1. Pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling
   Why done: Treat myopic traction maculopathy/foveoschisis or macular holes that threaten central vision.
   Procedure: Remove the vitreous gel, gently peel membranes, sometimes add gas tamponade; relieves traction so the macula re-settles.

2. Macular buckling
   Why done: Counteract the posterior bulge curvature under the macula when traction/splitting persists.
   Procedure: Implant a specially shaped buckle on the outside of the eye wall to push support under the macula.

3. Posterior scleral reinforcement (PSR)
   Why done: Provide extra strength to a very thin, bulging sclera to slow further outward bowing.
   Procedure: A graft (donor sclera or synthetic) is placed and sutured over the posterior pole. Availability and techniques vary.

4. Photodynamic therapy (PDT) with verteporfin
   Why done: For mCNV when anti-VEGF is unsuitable or unavailable.
   Procedure: IV verteporfin + targeted laser closes abnormal vessels with less collateral damage than thermal laser.

5. Retinal detachment repair (PPV with laser/cryotherapy, gas or oil)
   Why done: Treat retinal tears or detachment, which are more likely in long myopic eyes.
   Procedure: Reattach the retina, seal breaks, and stabilize the eye; timing is urgent.

Refractive laser surgery (LASIK/PRK) is often not advised in pathologic myopia with staphyloma due to thin tissues and higher risk of poor outcomes. Phakic IOLs may be considered in select cases, but do not treat the staphyloma.

Practical prevention strategies

Prevention focuses on children/teens (to reduce future risk) and adults (to avoid complications):

1. Early myopia control (outdoor time, myopia-control lenses, atropine if advised).

2. Regular eye exams with OCT when indicated.

3. Amsler grid self-checks weekly; seek help if new distortion or spot appears.

4. No eye rubbing; treat allergies to remove the urge.

5. Stop smoking; avoid secondhand smoke.

6. Manage blood pressure, diabetes, and lipids with your physician.

7. Use proper lighting and magnification to avoid strain.

8. Wear UV-blocking sunglasses outdoors.

9. Healthy diet and hydration to support vascular health.

10. Immediate care for flashes/floaters/curtain or sudden vision drop.

---

When to see a doctor

• New wavy or crooked lines on an Amsler grid or while reading.

• New central smudge/spot or sudden drop in vision.

• New floaters, flashes of light, or a dark curtain at the edge of vision.

• Eye pain, severe redness, or light sensitivity after an injection or surgery.

• Frequent prescription changes without clear vision improvement.

• Any pregnancy-related visual change that worries you.

• Routine follow-ups even when you feel fine—this disease is sneaky.

What to eat and what to avoid

Good to eat (supports eye and vessel health):

1. Leafy greens (spinach, kale) – lutein/zeaxanthin.

2. Oily fish (salmon, sardines) 1–2×/week – omega-3s.

3. Citrus/berries – vitamin C and flavonoids.

4. Nuts/seeds (almonds, walnuts, chia) – healthy fats, vitamin E.

5. Whole grains/legumes – steady blood sugar and vascular support.

Better to limit/avoid:

1. Smoking and vaping – harms small vessels and collagen.
2. Ultra-processed, high-sugar snacks – spike inflammation and glucose.
3. Excessive salt – worsens hypertension (hurts micro-circulation).
4. Heavy alcohol – oxidative stress and nutrition deficits.
5. Mega-doses of supplements without guidance – some (e.g., zinc, vitamin A) can harm if overdone.

FAQs

1. Can a posterior staphyloma be cured?
   Not today. We cannot shrink the bulge. We can protect vision by treating complications early and slowing myopia in kids.

2. Will stronger glasses fix the problem?
   Glasses correct focus, not tissue shape. They improve clarity if the macula is healthy, but do not repair the bulge.

3. What is the biggest danger?
   The main risks are myopic CNV, foveoschisis/macular holes, and retinal detachment—all can damage central vision if not treated promptly.

4. How often should I be checked?
   Your doctor will set a plan, commonly every 3–12 months, sooner if new symptoms appear. OCT is used to watch the macula.

5. Do anti-VEGF injections hurt?
   Numbing drops make it brief and tolerable. The payoff can be big vision protection for CNV.

6. How many injections will I need?
   Many people with mCNV need 1–3 injections in the first months, then as needed. Your OCT and vision guide the schedule.

7. Is PDT still used?
   Yes, but less often. It’s for people who cannot have anti-VEGF or when doctors judge it best for a specific case.

8. Can children develop staphyloma?
   It is uncommon in young kids but risk rises with rapid progressive high myopia. That’s why myopia control is vital.

9. Is laser vision correction safe for me?
   In pathologic myopia with staphyloma, laser refractive surgery is often discouraged. It does not treat the staphyloma and may carry extra risks.

10. Will special myopia lenses really help my child?
    Modern myopia-control spectacles or contact lenses can slow progression, lowering future risk.

11. Do supplements work?
    Supplements support general eye health, but do not cure staphyloma. Discuss a safe, balanced plan with your doctor.

12. What home test can I use?
    The Amsler grid is simple: look at the center dot daily/weekly; if lines look wavy or a square is missing, call your doctor.

13. Can I still exercise?
    Yes—regular, moderate exercise is good for vascular health. Avoid high-impact head trauma and follow your doctor’s advice after injections or surgery.

14. What about pregnancy?
    Most pregnancies are uneventful for eyesight, but report any new distortion, flashes, or floaters quickly.

15. What is my long-term outlook?
    With good follow-up, quick treatment of CNV or traction, and healthy habits, many people maintain useful vision for years.
