Wagner Syndrome

Wagner syndrome is a rare, inherited eye condition that mainly affects the vitreous (the clear gel that fills the eye) and the retina (the light-sensitive layer at the back of the eye). The most typical early sign is an “optically empty” vitreous—when the doctor looks in with a slit lamp or ophthalmoscope, the central gel looks unusually clear or “empty,” while thin veils or strands may be seen near the edges. Over time, people can develop myopia (short-sightedness), early cataracts, changes in the retina and retinal pigment epithelium (RPE), and sometimes retinal detachment or glaucoma. Vision can slowly worsen from childhood or the teenage years onward, though the rate and severity vary widely even within the same family. Wagner syndrome is autosomal dominant, meaning a change (variant) in a single copy of the responsible gene can cause disease and can be passed from a parent to a child. The known gene is VCAN, which makes a large structural protein called versican that helps organize the gel of the vitreous and the supportive “scaffolding” around cells. When versican is altered, the vitreous and retina lose normal structure and support, leading to the problems seen in this condition. EyeWikiMDPINCBI

Wagner syndrome is a rare, inherited eye condition that mainly affects the clear gel (the vitreous) and the light-sensitive layer at the back of the eye (the retina). In Wagner syndrome, the vitreous becomes thin and looks “optically empty,” and delicate, avascular (no blood vessel) strands or veils can form inside it. Over time this can lead to nearsightedness (myopia), presenile cataract, chorioretinal atrophy (gradual thinning of the retina and the layer underneath), night vision problems, and sometimes retinal detachment. The condition is usually autosomal dominant, which means a child has a 50% chance of inheriting it from an affected parent. Most people develop signs in childhood or adolescence and symptoms progress slowly across life. The disease is caused by changes (mutations) in the VCAN gene, which makes a large structural protein called versican—a key building block of the vitreous and surrounding tissues. Changes in VCAN alter versican splice forms and disturb the normal “scaffolding” of the vitreous, which in turn stresses the retina over many years.

Types

Doctors now think of Wagner syndrome as part of a spectrum of conditions caused by changes in the same VCAN gene. Two names appear most often:

1. Classic Wagner syndrome (WS).
   This is the “original” description: an optically empty vitreous, vitreous veils, progressive chorioretinal atrophy (thinning of layers of the retina and its supporting tissue), early cataract, and sometimes retinal detachment. Systemic (whole-body) problems are typically absent, which helps doctors distinguish it from some other inherited vitreoretinopathies. EyeWikidisorders.eyes.arizona.edu

2. Erosive vitreoretinopathy (ERVR).
   ERVR looks very similar and is allelic (caused by changes in the same gene). Some researchers view ERVR as a more severe or erosive end of the same VCAN spectrum; others treat it as a closely related diagnosis. Either way, both WS and ERVR share the autosomal dominant inheritance, the hallmark “empty vitreous” with avascular strands/veils, and a risk of tractional complications. Importantly, unlike Stickler syndrome, systemic features are usually not present in WS/ERVR. Ento KeyIOVS

Key idea in simple words: “Wagner” and “ERVR” are two labels on a sliding scale of the same gene problem (VCAN). The eye gel loses normal structure, the retina loses support, and traction or atrophy can follow. Ento Key

Causes

Important note in plain English: Strictly speaking, Wagner syndrome itself is caused by a disease-causing change in the single gene VCAN. Everything else below explains how and why the eye problems happen (mechanisms), and what triggers can make the complications worse or appear sooner. Think of these as drivers of the eye problems, not independent root causes of the syndrome.

1. VCAN gene variant (the root cause).
   A pathogenic change in the VCAN gene alters versican, a key structural molecule in the vitreous and surrounding tissues, setting the stage for the entire disease process. Autosomal dominant inheritance means a single altered copy is enough. MDPIEyeWiki

2. Abnormal versican splice-variant balance.
   Versican exists in several isoforms (V0, V1, V2, V3) made by alternative splicing. Certain splice-site variants change the ratio of these isoforms, disrupting the normal gel network in the vitreous. Nature

3. Disorganized extracellular matrix (ECM).
   Versican helps the ECM scaffold. When its structure or amount is wrong, the gel framework becomes unstable, making the vitreous “empty-looking” and the retina less supported. MDPI

4. Vitreous syneresis (liquefaction).
   The vitreous gel breaks down earlier and becomes more watery. This reduces the soft support that normally cushions the retina. disorders.eyes.arizona.edu

5. Abnormal vitreoretinal adhesions.
   Thin strands and veils can stick abnormally at the equator or periphery. These create traction (pulling forces) on the retina, which can cause tears or detachment. Ento Key

6. Peripheral avascularity and vascular anomalies.
   Fluorescein and OCT angiography may show unusual peripheral vessels or capillary loss in parts of the retina, which can contribute to atrophy and traction changes. gene.visionPubMed

7. Chorioretinal atrophy progression.
   The supporting layers thin over time, weakening the retina and making visual field and night vision problems more likely. disorders.eyes.arizona.edu

8. Myopia and axial elongation.
   Many people with Wagner have mild to severe myopia, which increases axial length and may raise the risk of peripheral retinal tears. ScienceDirect

9. Early cataract formation.
   Lens clouding can progress and reduce vision; cataract surgery later may be needed but also carries special retinal detachment considerations because of the vitreoretinal traction risk. disorders.eyes.arizona.edu

10. Inflammatory episodes (e.g., anterior uveitis in some families).
    Although WS is usually nonsyndromic, some reports describe anterior uveitis without synechiae; inflammation can worsen vitreoretinal traction or edema. ResearchGate

11. Epiretinal membrane (ERM) formation.
    Scar-like membranes on the macula can wrinkle the retina (macular pucker) and blur or distort central vision.

12. Retinal tears from traction.
    Abnormal strands + liquefied gel + axial elongation can pull on thin peripheral retina, creating tears that may lead to retinal detachment. disorders.eyes.arizona.edu

13. Vitreous hemorrhage (rare trigger).
    Traction can sometimes tear small vessels, causing floaters and temporarily clouded vision, and complicating the view of the retina.

14. Neovascular glaucoma (uncommon but reported).
    Severe retinal ischemia can promote new vessel growth on the iris/angle, with a risk of high eye pressure and vision loss if untreated. disorders.eyes.arizona.edu

15. Aging of collagen and hyaluronan in the vitreous.
    Natural aging changes can accelerate syneresis in already fragile vitreous, compounding the traction problem.

16. Surgical triggers (posterior capsulotomy or YAG after cataract surgery).
    In predisposed eyes, sudden changes in vitreous support can slightly increase retinal detachment risk; careful follow-up is important.

17. Trauma.
    Even minor blunt trauma can pull on abnormal adhesions and increase the risk of retinal tears.

18. Overlapping phenotypes (misclassification issues).
    Because Wagner overlaps with FEVR and Stickler syndrome, late recognition or mislabeling can delay preventive retina care (like prophylactic laser), indirectly allowing more traction events. PubMed

19. Microvascular dysfunction near traction sites.
    OCTA studies suggest that traction can reduce local capillary flow, which may promote localized atrophy over time. PubMed

20. Family modifiers and environment.
    Even with the same VCAN variant, family members can have different severity, likely due to modifier genes and environment (for example, level of myopia, lifetime eye rubbing, or trauma exposure). Ento Key

Symptoms

1. Blurry distance vision (myopia).
   Short-sightedness often appears or worsens in childhood or adolescence, making far objects look blurred. ScienceDirect

2. Floaters.
   You may see “spots,” “specks,” or cobweb-like shadows caused by vitreous strands or tiny clumps in the liquefied gel.

3. Night vision difficulty (nyctalopia).
   Because the retina and RPE can thin, seeing in dim light can slowly worsen. ERG often shows reduced rod and cone responses. disorders.eyes.arizona.edu

4. Glare and light sensitivity.
   Early cataract or macular changes can make lights seem harsh, especially at night.

5. Distortion (metamorphopsia).
   Lines can look wavy if an epiretinal membrane or macular traction develops.

6. Intermittent “flashes” (photopsias).
   Traction on the peripheral retina can stimulate the light-sensing tissue and cause brief flashes.

7. Peripheral shadow or curtain.
   A spreading dark shadow from the side of vision can signal retinal detachment, which is urgent.

8. Colors look dull.
   Macular changes or diffuse retinal atrophy can dampen color vividness.

9. Progressive central blur.
   As the macula thins or develops membranes, fine detail slowly degrades.

10. Frequent prescription changes.
    Worsening myopia or astigmatism can cause repeated updates to glasses.

11. Visual field defects.
    Peripheral retina changes cause patchy blind spots or narrowed side vision. NCBI

12. Halos around lights.
    Early cataract or corneal surface dryness can create rings around headlights.

13. Eye pressure symptoms (rare).
    If glaucoma develops, some people notice eye discomfort, headaches, or further field loss. NCBI

14. Sudden drop in vision after a new floater or flash.
    This can mean vitreous hemorrhage or retinal detachment—needs immediate care.

15. Occasional redness or mild ache (if uveitis occurs).
    Some families report anterior uveitis, which can cause irritation or mild pain. ResearchGate

Diagnostic tests

A) Physical Exam

1. Visual acuity testing
   This is the eye chart test. It measures how small of a letter you can read at a standard distance. In Wagner syndrome, acuity can be reduced by myopia, cataract, macular changes, or retinal detachment.

2. Refraction and ocular biometry
   Refraction measures your glasses prescription. Biometry measures axial length (front-to-back size) of the eye. Many with Wagner have myopia and sometimes longer axial length, which relates to retinal tear risk. ScienceDirect

3. Slit-lamp biomicroscopy
   This is a microscope exam of the front and middle of the eye. In Wagner syndrome the doctor may note an “optically empty” vitreous centrally, with fibrillar condensations or veils toward the periphery, and early cataract. EyeWiki

4. Intraocular pressure (IOP) measurement
   A quick pressure check helps detect glaucoma, which, while not universal, is reported in Wagner syndrome and can worsen vision if untreated. NCBI

B) Manual Tests

5. Dilated indirect ophthalmoscopy with scleral depression
   This is a hands-on, detailed peripheral retina exam. The doctor uses a bright light and a lens to check for thin areas, lattice-like patches, small tears, and traction ridges. It is essential in conditions with vitreoretinal traction. disorders.eyes.arizona.edu

6. Amsler grid
   A simple grid of lines you look at to detect distortion or missing spots from macular disease or membranes (metamorphopsia).

7. Visual field testing (kinetic or static perimetry)
   A visual field maps your side vision. Losses appear as blind-spot areas or constricted fields when the periphery is affected. NCBI

8. Pupil exam (for relative afferent pupillary defect, RAPD)
   A simple swinging-flashlight test can show an RAPD if one eye’s retina/optic nerve is significantly less healthy—useful when atrophy or detachment is asymmetric.

C) Lab & Pathological Tests

9. Targeted VCAN genetic testing (sequencing + CNV analysis)
   Confirming a pathogenic variant in VCAN provides a definitive diagnosis, guides family counseling, and helps distinguish WS/ERVR from Stickler syndrome (COL2A1) and FEVR (LRP5/FZD4/TSPAN12). Gene panels for inherited vitreoretinopathies commonly include these genes. NCBIPubMed

10. Segregation analysis in family members
    Testing relatives can show whether the VCAN variant tracks with disease in the family, strengthening the diagnosis and identifying at-risk relatives who need routine retinal follow-up. PubMed

11. Splice-effect or RNA studies (specialized/center-based)
    For some splice-site variants, labs may assess versican isoform balance (V0–V3) in blood-derived RNA to prove the mechanism (research or specialized diagnostics). Nature

12. Differential-diagnosis gene testing (Stickler, FEVR, XLRS as indicated)
    If the picture is unclear, testing COL2A1/COL11A1 (Stickler), LRP5/FZD4/TSPAN12 (FEVR), or RS1 (X-linked retinoschisis) can exclude look-alike disorders with different management nuances. PubMed

D) Electrodiagnostic Tests

13. Full-field electroretinography (ERG)
    ERG measures electrical responses from rod and cone cells. In Wagner syndrome, ERG often shows reduced b-wave amplitudes and elevated dark-adaptation thresholds, reflecting general retinal dysfunction that can precede obvious changes. disorders.eyes.arizona.edu

14. Multifocal ERG (mfERG)
    mfERG maps central retinal function in many tiny zones at once, useful for early or subtle macular dysfunction from membranes or atrophy.

15. Electro-oculography (EOG)
    EOG evaluates RPE function. Abnormal values can support the presence of RPE involvement in Wagner-related atrophy.

16. Dark adaptometry
    This test tracks how quickly vision recovers in the dark after bright light. Slowing fits with rod system involvement in Wagner syndrome.

E) Imaging Tests

17. Optical coherence tomography (OCT)
    OCT uses light waves to take cross-sectional pictures of the retina. It shows epiretinal membranes, vitreomacular traction, macular thinning, or cyst-like spaces, guiding treatment decisions. PubMed

18. Fluorescein angiography (FA)
    A dye test that images retinal blood flow. In Wagner syndrome, FA may show peripheral vascular anomalies, leakage, or areas of non-perfusion, especially where traction exists. gene.vision

19. OCT angiography (OCTA)
    A non-dye scan that maps retinal capillaries. Recent reports in Wagner syndrome describe perivascular loss of superficial capillary plexus near traction zones—helpful to understand why certain patches of atrophy appear. PubMed

20. B-scan ocular ultrasound
    When the view is cloudy (e.g., dense cataract or vitreous hemorrhage), B-scan can reveal vitreous membranes, tractional ridges, and retinal detachment behind opaque media.

Drug Treatments

Important: There is no pill or drop that “cures” VCAN mutations. Medicines below target complications like cystoid macular edema (CME), inflammation, or high eye pressure. Doses are common clinical starting points—your ophthalmologist personalizes them.

1. Topical carbonic anhydrase inhibitor (CAI): Dorzolamide 2%
   Typical use: 1 drop 3×/day.
   Purpose: Reduce CME and sometimes IOP.
   Mechanism: Increases fluid pumping across the retina/RPE; reduces retinal swelling. Evidence supports CAIs improving CME in inherited retinal diseases. PMCJAMA NetworkIOVS
   Side effects: Bitter taste, stinging, rare allergy.

2. Oral acetazolamide (CAI)
   Dose (adult starting): 250 mg 2–3×/day (renal dose adjust).
   Purpose: Alternative/adjunct for CME or to lower IOP.
   Mechanism: Systemic CAI effect reduces retinal edema and aqueous production. ScienceDirect
   Side effects: Tingling, fatigue, kidney stones, metabolic acidosis; avoid in sulfa-allergy, pregnancy (discuss with doctor).

3. Topical NSAID (e.g., ketorolac 0.5%)
   Use: 1 drop 4×/day for CME adjunct or post-op inflammation.
   Mechanism: Prostaglandin inhibition reduces macular inflammation; often combined with steroid.
   Side effects: Stinging, rare corneal issues with prolonged use.

4. Topical corticosteroid (e.g., prednisolone acetate 1%)
   Use: 1 drop 4×/day, then taper as directed.
   Purpose: Calm intraocular inflammation that can worsen edema.
   Side effects: IOP rise, cataract acceleration; requires monitoring.

5. Intravitreal corticosteroid implant (dexamethasone 0.7 mg)
   Use: Office injection for recalcitrant CME.
   Mechanism: Sustained steroid reduces retinal inflammation/edema when drops/pills fail; comparative data in inherited dystrophies suggest stronger anatomical effect than CAIs in some settings. Frontiers
   Side effects: IOP spikes, cataract progression; requires close follow-up.

6. IOP-lowering drops (beta-blocker: timolol 0.5%)
   Use: 1 drop 2×/day if ocular hypertension/glaucoma develops (can occur after vitrectomy or steroid use). ScienceDirect
   Mechanism: Lowers aqueous production → lower IOP.
   Side effects: Fatigue, bradycardia/bronchospasm (systemic absorption).

7. IOP-lowering drops (prostaglandin analog: latanoprost 0.005%)
   Use: 1 drop at bedtime.
   Mechanism: Increases uveoscleral outflow to lower IOP.
   Note: Rarely can worsen/post-op CME—your doctor weighs risks/benefits in macular disease.

8. Cycloplegic for painful ciliary spasm (e.g., homatropine 5%)
   Use: 1 drop 2–3×/day short-term.
   Purpose: Comfort during acute inflammation (if present).
   Side effects: Light sensitivity, blurred near vision.

9. Antibiotic prophylaxis (peri-operative use only)
   Use: Around surgery or intravitreal procedures per local protocol.
   Purpose: Lower infection risk.
   Note: Not a chronic therapy; stewardship matters. ScienceDirect

10. **Intravitreal anti-VEGF (e.g., bevacizumab 1.25 mg) — case-by-case
    Purpose: If secondary neovascular problems or macular leakage occur (less typical in Wagner, more in other entities).
    Mechanism: Blocks VEGF-driven leakage.
    Note: Not routinely needed in classic Wagner syndrome but may be helpful in selected complications identified by your retina specialist. PMC

Dietary “Molecular” Supplements

These do not treat the gene change. They may support general retinal/vascular health. Always discuss with your doctor, especially if pregnant, anticoagulated, or with kidney stones.

1. Omega-3 DHA/EPA — 1,000 mg/day combined: membrane support, anti-inflammatory.

2. Lutein (10 mg) + Zeaxanthin (2 mg) daily: pigment antioxidants that enhance contrast/glare tolerance.

3. Vitamin C (≈500 mg/day): antioxidant recycling; collagen support.

4. Vitamin E (≤400 IU/day): membrane antioxidant (avoid high doses if on anticoagulants).

5. Zinc (25–40 mg/day) + Copper (≈2 mg/day): enzyme co-factors; balance copper to avoid deficiency.

6. Coenzyme Q10 (100–200 mg/day): mitochondrial support in high-energy retinal tissue.

7. Alpha-lipoic acid (300–600 mg/day): redox cycling; insulin-sensitizing in diabetics.

8. Taurine (500–1,000 mg/day): abundant retinal amino sulfonic acid; osmotic/photoreceptor support.

9. Resveratrol (100–200 mg/day): antioxidant/AMPK signaling; theoretical neuroprotection.

10. Bilberry extract (80–160 mg/day): anthocyanins; microvascular support and night-vision comfort (evidence mixed).

Evidence note: Most data for supplements come from other retinal conditions (e.g., AMD, RP). There are no robust clinical trials proving benefit specifically in Wagner syndrome; use is discretionary and adjunctive.

Regenerative/Stem Cell” Drugs

Because your outline requests these specifically: there are no approved immune-booster, regenerative, or stem-cell drugs for Wagner syndrome as of today. Using such products outside a regulated clinical trial (especially in private clinics) has caused severe harm in other eye diseases. What’s realistic to mention:

1. AAV-based gene therapy targeting VCAN splicing (concept stage) — no clinical product.

2. CRISPR/base-editing approaches for intronic VCAN variants — preclinical idea only.

3. iPSC-derived retinal cell or RPE implants — tested for other diseases; not approved for Wagner.

4. Neurotrophic factor delivery (e.g., CNTF implants) — explored in RP; no established role in Wagner.

5. MSC-derived exosomes or cell therapy — experimental; avoid outside trials.

6. Anti-fibrotic/ECM-modulating drug strategies — theoretical; not in clinical use for VCAN disease.

Bottom line: No dosing exists because these are investigational. If interested, discuss legitimate clinical trials with your specialist; avoid unregulated stem-cell clinics.

Surgeries

1. Barrier laser photocoagulation (retinal laser)
   What: Outpatient laser burns around a retinal tear or thin area.
   Why: “Welds” retina to the wall to prevent progression to detachment.
   Notes: Frequently first-line when tears are found early. socalretina.com

2. Cryotherapy (freezing treatment)
   What: Freezing probe externally seals a peripheral break.
   Why: Alternative to laser when media is cloudy or the tear is very peripheral.
   Notes: Often combined with buckle in certain cases.

3. Scleral buckle
   What: A silicone band is sutured to the outer eye wall to indent it.
   Why: Relieves traction and supports retinal reattachment in rhegmatogenous detachment.
   Notes: Time-tested method; choice depends on break type and surgeon preference. PubMed

4. Pars plana vitrectomy (PPV) ± gas or silicone oil
   What: Microsurgery to remove abnormal vitreous, relieve traction, seal breaks (laser/cryotherapy), and tamponade with gas/oil.
   Why: Mainstay for complex tears/detachments in Wagner spectrum; allows direct management of traction and membranes.
   Notes: Effective but not risk-free (new tears, PVR, macular holes, glaucoma, endophthalmitis). Success relies on careful technique and vigilant follow-up. PMCEyeWikiNatureScienceDirect

5. Phacoemulsification cataract surgery
   What: Ultrasound removal of the cloudy lens with IOL placement.
   Why: Cataract is common and reduces function; surgery restores clarity.
   Notes: Retina status is checked first; combined procedures may be planned when traction/floaters are significant.

Preventions

You can’t prevent the gene change, but you can prevent or limit complications:

1. Regular retina exams (6–12 months or as advised).

2. Present urgently for flashes/floaters/curtain vision.

3. Avoid eye trauma; wear protective eyewear.

4. Control diabetes, blood pressure, lipids.

5. Do not smoke.

6. Manage post-op instructions carefully (e.g., head positioning).

7. Keep a personal baseline (Amsler grid/contrast apps) to notice changes.

8. Family screening and genetic counseling.

9. Choose experienced centers for vitreoretinal surgery.

10. Avoid unregulated stem-cell or “regenerative” clinics.

When to see a doctor now

• New floaters or flashing lights

• A dark curtain, shadow, or sudden field cut

• Sudden blur or distortion (straight lines look wavy)

• Painful red eye with halos (possible pressure spike)

• Sudden glare, starbursts, or rapid drop in night vision

• Any change after eye surgery or injection
  These can signal a retinal tear/detachment, macular edema, high pressure, or infection—same-day care is essential. PMC

What to eat and what to avoid

Helpful to eat (examples):

1. Fatty fish (salmon/sardine) 2–3×/week for omega-3s.

2. Dark leafy greens (spinach, kale) for lutein/zeaxanthin.

3. Colorful fruits/veg (berries, oranges, peppers) for antioxidants.

4. Nuts/legumes (almonds, walnuts, lentils) for vitamin E and minerals.

5. Whole grains & lean proteins to steady blood sugar and support healing.

Better to limit/avoid:

1. Smoking (any form) — retinal toxin and vascular harm.
2. Excess alcohol — worsens nutrition and recovery.
3. Ultra-processed, high-sugar foods — spikes glucose; harms microvasculature.
4. Very high-dose single vitamins without supervision (e.g., vitamin A) — potential toxicity.
5. Unregulated “stem-cell” products or supplements that claim to reverse blindness — avoid.

Frequently Asked Questions

1) Is Wagner syndrome the same as Stickler syndrome?
No. They can look similar in the vitreous, but Wagner is VCAN-related and typically lacks the systemic features (joint, facial, hearing) seen in Stickler (collagen gene disorders). A specialist differentiates them with genetics and imaging. Nature

2) What causes Wagner syndrome?
Mutations in the VCAN gene, which encodes versican, a key extracellular matrix protein in the vitreous and retina. Changes in splicing disturb vitreous architecture. MedlinePlusPMC

3) How is it inherited?
Autosomal dominant—each child of an affected parent has a 50% chance to inherit the variant. Genetic Diseases Info Center

4) When do symptoms start?
Usually childhood or adolescence, with slow progression. NCBI

5) What are the earliest signs?
High myopia, floaters, night vision problems, and an optically empty vitreous on exam. PubMed

6) Can retinal detachment happen?
Yes, it can occur in Wagner, though rates vary across the VCAN spectrum. Quick detection and surgery (laser, buckle, vitrectomy) can save vision. PMC+1

7) Is there a cure or a gene therapy now?
No approved cure or VCAN-targeted gene therapy as of now. Research concepts exist; participation in legitimate clinical trials may be an option in the future.

8) Are anti-VEGF injections part of routine care?
Not typically for classic Wagner because the vitreous changes are avascular. Anti-VEGF is used only if specific complications arise. PMC

9) How is cystoid macular edema treated?
Common options include topical/oral CAIs and sometimes steroids if needed; choice depends on OCT findings and your risk profile. PMCScienceDirectFrontiers

10) Will I definitely need surgery?
Not always. Many people are managed with monitoring and targeted laser. Surgery is done for retinal tears/detachments or significant cataract impacting function. PMC

11) Are operations risky in Wagner syndrome?
All eye surgeries have risks. In PPV for detachment, risks include new breaks, PVR, macular holes, infection, glaucoma; careful technique and follow-up help minimize these. EyeWikiNatureScienceDirect

12) Will I go blind?
Most people can retain useful vision with regular care and timely treatment of complications. Outcomes vary—early action is critical. PMC

13) Should my family get tested?
Yes. Genetic counseling and family screening are recommended for first-degree relatives. fulgentgenetics.com

14) Do supplements help?
They may support general eye health, but no supplement has proven to change the course of Wagner syndrome. Discuss personalized plans with your doctor.
