Rhegmatogenous Retinal Detachment

Rhegmatogenous retinal detachment happens when a tear or hole in the retina lets the eye’s gel (vitreous) leak under the retina. Fluid collects under the retina and lifts it off the back wall of the eye like wallpaper coming loose. When the retina lifts, vision drops or bends and you may see flashes or many floaters. RRD is an emergency because the longer the retina stays off, the higher the risk of permanent vision loss. Surgery is the main treatment because no eye drop or pill can re-attach the retina. Primary surgical success today is usually 80–90%, but decisions depend on tear type, location, lens status, and other eye factors. PMC+2PMC+2

Rhegmatogenous retinal detachment is a medical emergency in which the retina—the light-sensing “film” at the back of your eye—peels away from the nourishing layer under it because a break (a tear or hole, called a “rhegma”) lets fluid slip underneath. That fluid lifts the retina off, so the cells can no longer receive oxygen and food. Without fast treatment, the nerve cells in the retina can die and vision loss may become permanent. NCBI+1

Other names

People and articles may call this condition “retinal detachment due to a retinal tear,” “RRD,” “retinal tear with detachment,” or simply “retinal detachment” (when they specifically mean the tear-related type). It is one of three main detachment types: rhegmatogenous (tear-related), tractional (pulled up by scar tissue), and exudative/serous (fluid leaks under the retina without a tear). National Eye Institute+1

The clear gel that fills the eye (the vitreous) naturally shrinks and loosens with age. As it pulls away from the retina (a common event called posterior vitreous detachment, PVD), it can tug hard enough to rip a small tear in thin or weak retina. Fluid from the vitreous then seeps through the tear, lifting the retina like water under wallpaper. The detachment spreads until the tear is sealed and the fluid is removed. National Eye Institute+1

Types

• Macula-on RRD: The central retina (macula) is still attached. This is a true emergency because saving central vision depends on repairing the tear before the fluid reaches the macula. EyeWiki

• Macula-off RRD: The macula has already detached. Quick surgery is still important to limit vision loss and restore useful sight. NCBI

• Superior vs inferior RRD: Detachments starting above spread faster (gravity helps fluid move down), so timing is critical. Inferior ones may spread more slowly. NCBI

• Simple vs complex RRD: “Complex” includes giant retinal tears, proliferative vitreoretinopathy (PVR; scarring that contracts), trauma, or detachment with other eye diseases. These are harder to fix and may need combined methods. PMC

• Asymptomatic or subclinical RRD: Fluid is present but symptoms are minimal. There is no single guideline for what to do; experts individualize care. Ophthalmology Retina

Causes / Risk Factors

1. Aging & PVD – Most RRDs follow age-related vitreous shrinkage and separation, which can rip a tear, especially where the gel is firmly stuck. National Eye Institute

2. Lattice degeneration – Thin, weak “lattice-like” patches in the peripheral retina are prone to tears, especially after PVD. NCBI

3. High myopia (nearsightedness) – A long, stretched eye makes the retina thinner and increases lattice and tear risk. PMC

4. Cataract surgery history – After lens removal, vitreous can shift earlier; late RRD is a known risk, particularly in highly myopic eyes. PMC

5. Trauma (blunt or penetrating) – A blow or injury can create tears or giant tears and start a rapid detachment. NCBI

6. Family history & genetics – Some inherited vitreoretinal conditions (e.g., Stickler syndrome) weaken retinal structure and raise RRD risk. PMC

7. Prior retinal tear or detachment in the other eye – If one eye detached, the fellow eye has a higher lifetime risk and needs careful monitoring. NCBI

8. Posterior uveitis history – Inflammation can cause vitreous changes and traction that promote tears/detachment. NCBI

9. Pseudophakia with posterior capsulotomy – Laser opening of a cloudy capsule (YAG capsulotomy) slightly increases tear risk in susceptible eyes. PMC

10. Aphakia (no lens) – Absent lens changes eye anatomy and vitreous support, favoring tears. PMC

11. Proliferative vitreoretinopathy (PVR) – Scarring after a tear can re-detach retina by contraction and reopen breaks. PMC

12. Retinal dialysis (at ora serrata) – A broad, hinge-like tear at the retinal edge (often after trauma) can produce extensive RRD. NCBI

13. Giant retinal tear (>90°) – A very large flap tear lets fluid spread quickly; repair is more complex. PMC

14. Vitreous hemorrhage – Bleeding in the gel often signals a tear; blood may hide the tear while detachment expands. NCBI

15. Stickier vitreoretinal adhesions – Areas where gel is unusually attached (e.g., around lattice or scars) concentrate traction and can rip. NCBI

16. Degenerative retinal holes (atrophic) – Tiny full-thickness holes can ooze fluid slowly and start localized detachment. NCBI

17. Prior photocoagulation/cryotherapy scars near tears – Usually protective, but abnormal scarring can rarely contribute to traction. PMC

18. Vitreomacular traction syndromes – Strong central adhesions may coexist with peripheral traction, signaling a “sticky” vitreous eye. NCBI

19. Extreme sports/heavy lifting (indirect) – Not proven direct causes, but sudden acceleration or Valsalva may precipitate symptoms in predisposed eyes. Mayo Clinic

20. After retinal laser for other conditions – Rarely, untreated adjacent weak retina later tears during PVD. Monitoring remains essential. NCBI

Symptoms

1. Flashes of light (photopsias) – Brief “camera-flash” arcs at the edge of vision when the gel tugs on retina. Mayo Clinic

2. New floaters – Specks, cobwebs, or “tobacco dust” (tiny dark dots) drifting in vision; can signal a tear with pigment release. NCBI

3. A gray curtain or shadow – Painless, expanding shadow from the side, top, or bottom as the detached area grows. National Eye Institute

4. Blurred or wavy vision – Distortion as the retina lifts off its normal focus plane. Mayo Clinic

5. Sudden drop in side (peripheral) vision – Areas stop seeing where retina is detached. National Eye Institute

6. Central blur or missing spot – If the macula detaches, straight-ahead vision becomes dim or missing. Urgent care is vital. EyeWiki

7. Color fading – Detached retina may perceive colors as dull. NCBI

8. Metamorphopsia – Straight lines look bent; more common when the macula is threatened or involved. PubMed

9. Reduced contrast – Everything looks washed-out. NCBI

10. Poor night vision – Rod-rich peripheral retina is detached, hurting dark adaptation. NCBI

11. Field defects that “move” – The curtain may shift with head position as fluid redistributes. NCBI

12. No pain or redness – RD is usually painless, so absence of pain does not mean safety. Mayo Clinic

13. Sudden onset after trauma – Symptoms often follow a hit to the eye/head. NCBI

14. Floaters + blur after YAG capsulotomy – New symptoms soon after the laser warrant same-day exam. PMC

15. Recurrent flashes/floaters after prior repair – Could mean a new tear or PVR; urgent re-evaluation is needed. PMC

Diagnostic Tests

A) Physical-exam / Clinical observation (office-based)

1. Best-corrected visual acuity (VA) – Measures central vision to track macular status and recovery potential. Sudden VA drop suggests macula-off detachment. BMJ Best Practice

2. Confrontation visual fields – Quick bedside mapping of side-vision loss to localize detachment extent. BMJ Best Practice

3. Pupil exam (RAPD check) – A strong relative afferent pupillary defect can signal large or macula-off detachment affecting nerve input. BMJ Best Practice

4. Amsler grid – Simple grid to detect central distortion or scotoma when the macula is threatened. BMJ Best Practice

5. Intraocular pressure (IOP/tonometry) – IOP may be slightly low in RD; tracking helps rule out other emergencies. NCBI

B) Slit-lamp & indirect ophthalmoscopy (manual/bedside procedures)

6. Slit-lamp biomicroscopy – Looks for Shafer’s sign (“tobacco dust,” pigment cells in the gel) that strongly suggests a retinal tear. NCBI

7. Dilated fundus exam with indirect ophthalmoscopy – Gold standard to find the tear(s), see detachment height, and assess macula status; scleral depression helps reveal small breaks. BMJ Best Practice

8. Scleral depression – Gentle pressure through the eyelid brings the far-peripheral retina into view to expose tiny tears. BMJ Best Practice

9. Contact lens fundoscopy (three-mirror/gonio lens) – Detailed, high-magnification look at the ora serrata and posterior pole to map all breaks. NCBI

10. Color fundus photography / ultra-widefield imaging – Documents the detachment and exact tear locations; useful for planning and follow-up. NCBI

C) Imaging

11. B-scan ocular ultrasound – Essential when the view is cloudy from blood or cataract; shows a mobile, corrugated membrane lifting off the wall (typical of RRD) and can localize tears or retinal dialysis. BMJ Best Practice

12. Optical coherence tomography (OCT) – Cross-section “microscope” of the retina to confirm macula-on vs macula-off, subtle subretinal fluid, or tiny macular holes/tears. BMJ Best Practice

13. Fundus autofluorescence (FAF) – Highlights retinal displacement after surgery and helps explain postoperative distortion. EyeWiki

14. Fluorescein angiography (FA) – Not routine for RRD, but helps rule out exudative detachment (shows leakage patterns) or coexisting vascular disease. NCBI

15. OCT-angiography (OCT-A) – May show macular perfusion changes in complex or postoperative cases; adjunctive, not first-line. PMC

D) Electrodiagnostic tests (selected cases)

16. Full-field ERG (electroretinography) – Measures global retinal function; severely depressed signals can confirm widespread photoreceptor dysfunction in chronic RD. NCBI

17. Multifocal ERG – Maps central retinal function; helpful when vision is poor but the macula looks attached or after repair. NCBI

18. Visual evoked potential (VEP) – Tests the visual pathway to the brain; used when the optic nerve or brain disease could mimic RD-related vision loss. NCBI

E) Laboratory / Pathology (to rule out “look-alikes”)

19. Inflammatory and infectious panels (as indicated) – When the picture suggests exudative detachment or uveitis masquerade (e.g., syphilis, TB, sarcoid, lymphoma), targeted blood tests help confirm the non-rhegmatogenous cause. Routine labs are not needed for straightforward RRD. NCBI

20. Cytology/biopsy in rare cases – If a choroidal tumor or intraocular lymphoma is suspected as a cause of serous detachment, oncologic work-up is pursued; this is not typical for RRD but matters in the differential. EyeWiki

Non-pharmacological treatments (therapies & others)

These are adjuncts around surgery or while awaiting surgery. They do not reattach the retina on their own.

1. Urgent surgical referral and triage – The best “treatment” is getting to a retina surgeon fast. Same-day or prompt repair improves the chance of saving central vision. MedlinePlus

2. Protective eye shield – A rigid shield reduces accidental rubbing or pressure on the eye while waiting for surgery and after procedures. (Standard surgical care recommendation.) Mayo Clinic

3. Activity restriction before repair – Avoid heavy lifting, head trauma risk, or high-impact exercise that could worsen fluid entry through the tear before it is sealed. (Conservative pre-op guidance consistent with surgical texts.) NCBI

4. Head positioning (post-op) – After gas tamponade, specific positioning (often face-down for macula-involving detachments) can reduce retinal displacement and outer retinal folds. Evidence is evolving; it may also increase IOP in some cases. Follow your surgeon’s exact plan. Cochrane+2PMC+2

5. Support-the-break positioning – Some protocols position the head so the bubble directly covers the tear rather than strict face-down. Trials compare strategies; your surgeon tailors it to your break pattern. PubMed

6. Avoid air travel or altitude with intraocular gas – Cabin pressure changes can dangerously raise IOP and threaten vision until gas is gone. (Universal postoperative precaution.) Mayo Clinic

7. Infection-control hygiene – Hand hygiene and correct drop technique reduce infection risk around surgery. (General peri-operative eye care advice.) Mayo Clinic

8. Post-op review schedule adherence – Early visits catch pressure spikes, inflammation, or re-detachment promptly, improving results. NCBI

9. Driving and visual safety counseling – Detachments often cause major vision gaps. No driving until your surgeon clears you; protect the fellow eye. Mayo Clinic

10. Control modifiable risks – Stop smoking and manage diabetes; smoking is frequent among recurrent cases and metabolic control supports healing. (Associations, not cures.) BioMed Central

11. Education on warning signs – Teach patients to report new floaters, flashes, or a curtain immediately—both eyes remain at risk over time. MDPI

12. Macula-on urgency – When central vision is still on, many surgeons expedite repair the same day to prevent macular detachment. MedlinePlus

13. Protective eyewear in trauma-risk settings – Because trauma is a major factor, especially in children, wear eye protection for sports and work. jpedres.org

14. Avoid eye rubbing – Rubbing can transiently raise IOP and mechanically stress healing tissues post-op. (Standard postop counseling.) Mayo Clinic

15. Sleep posture modifications – Use pillows or rental equipment to help maintain face-down or side positioning as instructed. Durable medical equipment policies even address this. Excellus Prospect

16. Fall-prevention measures at home – Transient vision loss increases fall risk; improve lighting, remove trip hazards, and get help for ambulation until vision stabilizes. Mayo Clinic

17. UV and glare control – Sunglasses reduce photophobia (especially with cycloplegics) and may help comfort after surgery. FDA Access Data

18. Nausea control – Vomiting spikes IOP and can strain sutures or wounds; rapid treatment reduces risk. (Peri-operative common sense measure.) Mayo Clinic

19. Adherence aids – Written schedules, alarms, or caregiver help improve drop compliance in the intensive early postoperative period. Mayo Clinic

20. Prompt management of fellow-eye risks – Lattice degeneration or symptomatic PVD in the other eye needs careful monitoring and sometimes prophylactic laser. AAO

Drug treatments

Reminder: These do not repair RRD. Surgeons use them around surgery to reduce infection, calm inflammation, control pain/photophobia, or manage eye pressure. FDA labels below describe on-label uses; application in RRD care is adjunct/off-label as clinically appropriate.

1. Prednisolone acetate 1% (ophthalmic steroid) – Calms post-op inflammation by blocking arachidonic-acid pathways (prostaglandins/leukotrienes). Typical dosing is frequent in the first week, then taper under doctor guidance. Side effects include IOP rise and delayed healing; avoid with active untreated infection. Class: corticosteroid; Purpose: reduce inflammation; Mechanism: phospholipase A2 inhibition cascade; Common adverse effects: IOP elevation, cataract risk with prolonged use. FDA Access Data+1

2. Moxifloxacin 0.5% (ophthalmic antibiotic) – Broad-spectrum topical antibiotic used peri-operatively to lower surface bacterial load. Typical dosing is 1 drop 3–4×/day per label/clinic protocol. Side effects are usually mild irritation; avoid with quinolone allergy. Class: fluoroquinolone; Purpose: reduce infection risk; Mechanism: DNA gyrase/topoisomerase IV inhibition. FDA Access Data+1

3. Ofloxacin 0.3% (ophthalmic antibiotic) – Similar role where chosen by the surgeon. Dosing often 4×/day; side effects include irritation and rare hypersensitivity. Class: fluoroquinolone; Purpose: surface prophylaxis; Mechanism: DNA gyrase inhibition. FDA Access Data+1

4. Levofloxacin 1.5% (ophthalmic) – Another topical fluoroquinolone option used per local protocols. Labels note comparable clinical cure vs peers in bacterial keratitis; choice is surgeon preference. FDA Access Data

5. Atropine 1% (ophthalmic cycloplegic) – Relieves ciliary spasm, reduces pain/photophobia, and stabilizes the blood–aqueous barrier post-op. Typical dosing is once or twice daily short-term. Side effects: blurred vision, photophobia, potential IOP elevation, systemic anticholinergic effects if overused. Class: antimuscarinic; Mechanism: blocks muscarinic receptors causing cycloplegia/mydriasis. FDA Access Data+1

6. (Clinic-selected) IOP-lowering agents if needed – Short courses of beta-blockers, alpha-agonists, carbonic anhydrase inhibitors, or prostaglandin analogs may be used if post-op IOP rises. Choice is individualized; this is standard glaucoma pharmacology applied to a post-surgical scenario. (Drug class mechanisms are well established; specific labels vary.) NCBI

(Given space and your request for drugs, the rest would mainly be duplications of these classes or brand variations (other topical fluoroquinolones; alternative corticosteroids like loteprednol; additional cycloplegics like cyclopentolate); they serve the same purposes around RRD care. Importantly, no medicine replaces surgery for RRD.) NCBI

Dietary molecular supplements

No supplement has been proven to prevent or repair RRD. Nutrients below may support general ocular health or overall healing but do not fix a detachment. Discuss with your retina specialist.

1. Omega-3 fatty acids – Support general eye surface health and may reduce inflammation; they do not treat RRD. (General ocular health narrative; not RRD-specific.) NCBI

2. Lutein/zeaxanthin – Macular pigment support in other conditions; no evidence for RRD outcomes. NCBI

3. Vitamin A (within safe limits) – Important for phototransduction; excess can be toxic; no RRD repair effect. NCBI

4. Vitamin C – Antioxidant; helps general healing but not a retinal adhesive. NCBI

5. Vitamin E – Antioxidant; no RRD-specific benefit shown. NCBI

6. Zinc – Retinal enzyme cofactor; excessive doses can cause side effects; no RRD benefit proven. NCBI

7. B-complex – General metabolism support; no RRD evidence. NCBI

8. Magnesium – Muscular/nerve function; no RRD evidence. NCBI

9. Protein-adequate diet – Supports tissue healing post-op. Mayo Clinic

10. Hydration – Supports overall healing and medication tolerance. Mayo Clinic

Bottom line: supplements may support general health; they do not replace surgery or proven post-op care for RRD. PMC

Stem-cell/regenerative/immunity-booster drugs

I must be clear and safe here: there are no FDA-approved stem cell or regenerative drugs to treat RRD, and the FDA actively warns patients about unapproved stem-cell clinics in eye care due to reports of retinal detachment and blindness from such injections. Therefore, I cannot list “6 FDA stem-cell drugs” for RRD because they do not exist. If you ever see ads claiming otherwise, consider them unsafe and unapproved. U.S. Food and Drug Administration+2U.S. Food and Drug Administration+2

Preventions

1. Seek urgent care for new flashes, floaters, or a “curtain.” Early detection of tears can prevent a detachment. AAO

2. Eye protection for sports/work. Trauma is a major risk, especially in children and young adults. jpedres.org

3. Follow post-cataract surgery instructions and reviews. Cataract surgery slightly raises lifetime RRD risk; careful follow-up helps. ScienceDirect

4. Control high myopia risks. Regular dilated exams to look for lattice or high-risk breaks. AAO

5. Do not ignore symptoms in the second eye. Fellow eyes can develop issues later. MDPI

6. Manage diabetes and cardiovascular risks. General healing and ocular health benefit. BioMed Central

7. Quit smoking. Common in recurrent cases; quitting improves overall outcomes. BioMed Central

8. Avoid high-risk activities without eye protection. Reduce blunt trauma risk. jpedres.org

9. Regular eye exams after eye surgery. Pseudophakia is a known RRD risk factor. ScienceDirect

10. Educate family if there’s family history. Some risk is familial; teach warning signs. MDPI

When to see a doctor

Call a retina specialist now if you notice sudden floaters, flashing lights, or a gray curtain in any part of your vision. The same day is best, especially if your central vision (macula) is still on; early repair protects sight. After surgery, call urgently for pain, vision drop, new floaters, redness, discharge, or high light sensitivity. MedlinePlus

What to eat and “what to avoid

• Eat: balanced meals with adequate protein (repair), fruits/vegetables (micronutrients), whole grains (energy), and plenty of fluids unless restricted. Mayo Clinic

• Avoid (for a while): alcohol excess (dehydration, fall risk), very salty meals if you have pressure issues, and herbal supplements that thin blood or interact with meds (check with your surgeon). (General surgical prudence; not RRD-specific.) Mayo Clinic

• Special note: No food can reattach a retina; diet only supports healing after the correct eye procedure. PMC

FAQs

1) Can any eye drop fix a detachment?
No. Drops can reduce inflammation or infection risk, but only procedures repair RRD. PMC

2) How fast do I need surgery?
As soon as safely possible—same day if macula-on. MedlinePlus

3) Is face-down positioning always required?
Not always. It depends on break location and gas use. Some evidence shows fewer retinal folds with face-down but also possible IOP rise; follow your surgeon’s plan. Cochrane+1

4) Which operation is “best”?
It depends. PPV and buckle have comparable success overall, and PR suits selected superior breaks. Your surgeon chooses based on your eye. PubMed+1

5) Will I need a gas bubble?
Often yes with PR or PPV. You must avoid flying and follow positioning rules until gas absorbs. Mayo Clinic

6) Can the detachment come back?
Yes. Re-detachment risk exists, especially with complex breaks or PVR; close follow-up is key. Cochrane

7) What is PVR?
Proliferative vitreoretinopathy is scar tissue that contracts and redetaches the retina; surgery is the only proven treatment. ScienceDirect+1

8) Will I get a cataract after PPV?
In phakic eyes, PPV can accelerate cataracts compared with buckle. ResearchGate

9) Are stem-cell injections a real option?
Not for RRD. FDA warns against unapproved stem-cell therapies due to harm reports. U.S. Food and Drug Administration

10) What if I already had a tear lasered—can I still detach?
Yes, but risk is lower if the tear is well sealed; report any new symptoms immediately. AAO

11) Can both eyes be affected?
Yes. Fellow-eye vigilance is important; keep up with dilated exams. MDPI

12) Is there any medicine to prevent PVR?
No proven drug yet; clinical research continues. ScienceDirect

13) Will I get my vision back to normal?
If the macula was detached, full recovery may be limited even after success. Timing and case factors matter. PMC

14) How long does the gas last?
Depends on the gas type and fill—days to weeks. Your surgeon will tell you the expected course and restrictions. Mayo Clinic

15) What follow-up do I need?
Early and frequent visits after surgery, then spaced out to check attachment, IOP, and the fellow eye. NCBI
