Exudative (Serous) Retinal Detachment

Exudative retinal detachment, also called serous retinal detachment, is when fluid builds up under the retina without any tear or traction pulling it away. The retina is the light-sensitive layer at the back of the eye. Normally it lies flat against the retinal pigment epithelium (RPE). In exudative detachment, fluid leaks from blood vessels or from the choroid (the layer beneath the retina) and collects in the space between the sensory retina and RPE, lifting the retina off gently like a wet sheet. This separation interferes with vision, and the exact symptoms and recovery depend on why the fluid is there. The problem often comes from something else in the eye or body—such as inflammation, tumors, high blood pressure, or infections—and treating the underlying cause is key to fixing the detachment. EyeWiki ScienceDirect Nature

Exudative retinal detachment, also called serous retinal detachment, happens when fluid builds up under the retina without any tear or hole. This fluid pushes the sensory retina away from its normal position on the retinal pigment epithelium (RPE), causing partial or full detachment. Unlike rhegmatogenous detachment (which involves a break) or tractional detachment (which involves pulling), exudative detachment is due to leakage or inflammation from beneath the retina. The fluid comes from blood vessels or choroidal abnormalities and collects in the subretinal space, separating the retina and impairing vision.NCBI EyeWiki AAFP

Types of Exudative Retinal Detachment

Exudative detachments are usually classified not by a mechanical break (like rhegmatogenous) but by why fluid is leaking and accumulating. The main types or categories based on cause are:

1. Inflammatory – Inflammation in or around the choroid or retina makes blood vessels leaky and disrupts normal fluid handling. Examples include Vogt-Koyanagi-Harada (VKH) syndrome and posterior scleritis. Lippincott JournalsScienceDirect

2. Infectious – Eye infections (like tuberculosis-related choroiditis, syphilis, or ocular toxoplasmosis) can inflame and damage choroidal vessels or RPE, leading to leakage and detachment. ScienceDirect

3. Neoplastic – Tumors inside or behind the eye (such as choroidal melanoma, metastases, leukemia/lymphoma infiltration) disturb normal vascular integrity or produce exudation, causing fluid to collect. ScienceDirectScienceDirect

4. Vascular / Hydrostatic – Sudden or severe high blood pressure (malignant hypertension), preeclampsia/eclampsia, or other vascular dysregulation increases hydrostatic pressure in choroidal vessels, pushing fluid under the retina. AAFP

5. Central serous chorioretinopathy (CSCR) – A disorder of choroidal hyperpermeability causing idiopathic serous detachment of the neurosensory retina, often in stressed or corticosteroid-exposed individuals. EyeWikiNature

6. Uveal effusion syndrome – Rare condition where impaired scleral permeability and choroidal congestion cause fluid accumulation, leading to widespread serous detachments. Retina Today

7. Autoimmune / Immune-mediated – Diseases like VKH (already inflammatory but autoimmune in origin) or sympathetic ophthalmia with immune attack on melanocyte-containing tissues leading to exudation. Lippincott Journals

8. Posterior segment tumors causing secondary effects – Even without direct infiltration, tumors can alter local blood flow or induce inflammation causing exudation. BioMed Central

9. Choroidal ischemia / hypertensive choroidopathy – Damage to the choroidal circulation from systemic vascular disease causes breakdown of the outer blood-retinal barrier. AAFP

10. Nanophthalmos with secondary uveal effusion – Small eye with abnormal scleral thickness predisposes to impaired fluid drainage and secondary serous detachments. Retina Today

(These categories often overlap; for example, VKH is both inflammatory and autoimmune. The working clinician often thinks in terms of the underlying disease driving the leakage.) Nature

Causes of Exudative Retinal Detachment

Below are 20 distinct causes that lead to exudative retinal detachment, with brief explanations in very simple English:

1. Vogt-Koyanagi-Harada (VKH) syndrome – An autoimmune disease that inflames the uveal tract, making vessels leaky and causing fluid under the retina. Lippincott Journals

2. Posterior scleritis – Inflammation of the back part of the white of the eye (sclera) that spreads and causes fluid buildup beneath the retina. Lippincott Journals

3. Central serous chorioretinopathy (CSCR) – The choroid leaks fluid under the retina, often triggered by stress or steroid use. EyeWikiNature

4. Choroidal melanoma – A cancer in the choroid that disturbs normal blood vessel behavior and causes leaking fluid. ScienceDirectNature

5. Choroidal metastasis – Cancer from elsewhere (like breast or lung) spreading to the eye, making fluid collect under the retina. ScienceDirectNature

6. Leukemia / lymphoma infiltration – Blood cancers can invade eye tissues, causing inflammation and fluid leakage. ScienceDirect

12. Infectious chorioretinitis (e.g., tuberculosis, syphilis, toxoplasmosis) – Infections can inflame and damage the choroid/retina, allowing fluid to collect. ScienceDirect

13. Choroidal hemangioma – A benign blood vessel tumor that leaks plasma under the retina. BioMed Central

14. Idiopathic (unknown) leakage / chronic CSCR variants – Some detachments have no clearly identified trigger but behave like serous leaks. EyeWiki

15. Ocular ischemic syndrome – Poor blood flow to the eye causes tissue stress and breakdown of barriers, with fluid escape. ScienceDirect

16. Systemic autoimmune diseases (e.g., lupus) – Body-wide inflammation can affect the choroid and lead to exudation. ScienceDirect

17. Post-surgical inflammation or choroidal effusion (e.g., after glaucoma surgery) – Surgery can trigger leakage or fluid accumulation in the eye layers. Retina Today

18. Nanophthalmos-related effusion (small eye syndrome) – Structural abnormality that traps fluid, causing serous detachment. Retina Today

19. Thickened choroid disorders (pachychoroid spectrum beyond CSCR) – Abnormally large choroidal vessels alter pressure and permeability, leaking fluid. BioMed Central

20. Secondary effects from intraocular tumors not directly invading (paraneoplastic-like vascular changes) – Tumors elsewhere can indirectly change eye vessel behavior, leading to leakage. ScienceDirect

Symptoms of Exudative Retinal Detachment

Exudative retinal detachment often causes vision changes that develop over hours to days. The 15 common symptoms, in simple language:

1. Blurred vision – Vision becomes soft or out of focus because the retina is lifted and cannot process light properly. EyeWiki

2. Decreased vision/sharpness – Overall loss of clear sight, sometimes sudden depending on location and amount of detachment. AAFP

3. Distorted vision (metamorphopsia) – Straight lines look wavy or bent because the retina is no longer flat. Retina Today

4. Central dark spot or blind spot (scotoma) – A missing area in vision if the detachment covers central retina (macula). Retina Today

5. Color changes or desaturation – Colors may look faded or less vivid due to impaired retinal function. Retina Today

6. Photophobia (light sensitivity) – Associated when inflammation is present, making bright light uncomfortable. Lippincott Journals

7. Floaters (less common than in rhegmatogenous) – Small shadows or spots in vision; in exudative cases, they are usually from associated inflammation or hemorrhage. MD Searchlight

8. Visual field loss – Parts of peripheral or central vision may be gone depending on where fluid lifts the retina. EyeWiki

9. Sudden vision changes – Especially when underlying causes like hypertension cause rapid leakage. AAFP

10. Double vision (if severe elevation distorts eye optics) – Rare, but large detachments can interfere with how the eye focuses, leading to diplopia. (Inference based on mass effect in extensive detachment). BioMed Central

11. Eye redness – When inflammation or underlying uveitis accompanies the detachment. Lippincott Journals

12. Eye pain (especially with scleritis or inflammatory cause) – Inflammatory causes often bring discomfort or deep ache. Lippincott Journals

13. Reduced contrast sensitivity – Difficulty distinguishing shades or fine detail because the photoreceptors are misaligned. Retina Today

14. Appearance of a “shadow” or “curtain” (sometimes reported even in exudative, though more typical of rhegmatogenous) – A subjective sense of part of vision being obscured. MD Searchlight

15. Fluctuating vision (especially in inflammatory or CSCR cases) – Vision may improve or worsen somewhat until the underlying cause is treated. EyeWiki

Non-Pharmacological Treatments

1. Treat the Underlying Systemic Disease: Controlling systemic inflammation (e.g., autoimmune uveitis) or hypertension stops further fluid leakage. Good management of blood pressure reduces choroidal hydrostatic stress.AAFP

2. Observation with Close Monitoring: In mild cases where the cause is being addressed (e.g., resolving inflammation), watching closely without immediate intervention can allow spontaneous fluid resorption. This avoids overtreatment.AAFP

3. Stress Reduction: Central serous chorioretinopathy is linked to stress and elevated corticosteroid levels in the body; stress management (meditation, therapy, sleep hygiene) can decrease recurrence risk.EyeWiki

4. Avoidance or Reduction of Exogenous Corticosteroids: Since corticosteroid use (systemic, topical, inhaled) is a known trigger for CSR and some exudative detachments, stopping nonessential steroids eliminates a major aggravating factor.EyeWiki

5. Blood Pressure Control via Lifestyle: Dietary sodium reduction, weight management, and regular aerobic exercise help maintain healthy blood pressure to reduce hypertensive choroidopathy risk.AAFP

6. Sleep Apnea Management: Untreated sleep apnea contributes to vascular dysregulation and may worsen ocular perfusion; use of CPAP and weight loss can support retinal health. (Inference based on vascular risk reduction principles.)American Osteopathic Association

7. Smoking Cessation: Smoking increases oxidative stress and vascular dysfunction, indirectly raising risk of choroidal circulation problems and impeding healing.PMC

8. Healthy Diet to Reduce Systemic Inflammation: Eating anti-inflammatory foods (fruits, vegetables, omega-3 rich fish) reduces systemic inflammation burden that could contribute to vascular leakage.Real SimpleEatingWell

9. Control of Diabetes and Lipids: Good glycemic and lipid control preserve microvascular integrity, minimizing secondary causes of choroidal leakage or ischemia that might provoke exudation.American Osteopathic Association

10. Avoiding High Altitude Rapid Ascent (when applicable): Sudden pressure changes can exacerbate subretinal fluid dynamics in susceptible individuals; gradual acclimatization lessens stress. (General physiologic principle; moderate inference.)AAFP

11. Hydration and Electrolyte Balance: Maintaining normal plasma osmolarity helps keep fluid dynamics stable; severe dehydration or overhydration can shift fluid compartments unfavorably. (General medical physiology inference.)AAFP

12. Head Elevation During Sleep: Mild gravitational assistance may help slow subretinal fluid accumulation in early cases, giving more time for underlying therapy to work. (Common conservative ophthalmic advice.)AAFP

13. Protective Eyewear: Preventing ocular trauma avoids confusing coexisting retinal issues and prevents secondary complications that might combine with an exudative process.Cleveland Clinic

14. Prompt Treatment of Ocular Infections: Early eradication of infections prevents inflammatory exudation and fluid accumulation under the retina.AAFP

15. Regular Eye Exams When High Risk: People with known inflammatory eye disease, hypertension, or choroidal tumors benefit from periodic retinal checks to catch early fluid before large detachment.AAFP

16. Light Exposure Moderation: While not directly causative, avoiding excessive UV exposure and bright glare can lower oxidative stress on the retina, helping overall health. (General ocular health practice.)American Osteopathic Association

17. Weight Management: Obesity contributes to vascular dysregulation and hypertension; weight normalization reduces risk factors.EatingWell

18. Mindful Medication Review: Periodic review of systemic medications to remove unnecessary ones that could increase fluid leakage (like steroids or certain vasodilators) is preventive.EyeWiki

19. Reducing Caffeine (in some CSR cases): Some practitioners recommend reducing caffeine intake in chronic CSR, as caffeine can influence cortisol metabolism and circulation; evidence is limited but often trialed in conservative management. (Low-level inference.)EyeWiki

20. Patient Education and Symptom Awareness: Teaching patients to recognize sudden floaters, flashes, or visual shadows leads to early presentation and better outcomes.Cleveland ClinicMayo Clinic

Drug Treatments

1. Intravitreal Anti-VEGF Agents (Ranibizumab, Bevacizumab, Aflibercept): These block vascular endothelial growth factor, reducing leakage from abnormal choroidal or retinal neovascular vessels and helping resolve subretinal fluid especially in conditions like Coats disease or secondary choroidal neovascularization. Typical dosing is monthly injections initially (e.g., ranibizumab 0.5 mg intravitreal every 4 weeks), then titrated based on response. Side effects include rare endophthalmitis, intraocular pressure spikes, and systemic vascular risks.BMJ OphthalmologyRetina Today

2. Corticosteroids (Periocular or Intravitreal or Systemic): Used when inflammation drives fluid accumulation (e.g., uveitis). Examples include intravitreal triamcinolone acetonide (4 mg) or periocular depot injections. They reduce vascular permeability by inhibiting inflammatory cytokines. Side effects include elevated intraocular pressure and cataract formation. Systemic steroids are used for severe posterior segment inflammation under careful supervision.PMCScienceDirect

3. Mineralocorticoid Receptor Antagonists (Eplerenone, Spironolactone): These are used off-label in chronic central serous chorioretinopathy to reduce choroidal vascular hyperpermeability and fluid leakage. Typical oral dosing is eplerenone 25 mg daily, possibly increasing to 50 mg, with monitoring of potassium and renal function. Side effects include hyperkalemia and hormonal effects (gynecomastia with spironolactone).EyeWiki

4. Systemic Immunosuppressants (e.g., Methotrexate, Mycophenolate Mofetil): When autoimmune inflammation (such as Vogt-Koyanagi-Harada or posterior uveitis) causes exudation, these agents suppress immune-mediated leakage. Dosing varies by agent; methotrexate often started weekly (7.5–25 mg) with folic acid supplementation. Side effects include liver toxicity, bone marrow suppression, and gastrointestinal upset.AAFP

5. Anti-hypertensive Medications: In hypertensive choroidopathy underlying detachment, urgent blood pressure control with appropriate antihypertensives (e.g., beta-blockers, ACE inhibitors) reduces choroidal vessel stress and leakage. The choice depends on comorbidities; therapy is titrated to safe target blood pressures under medical supervision.AAFP

6. Carbonic Anhydrase Inhibitors (Acetazolamide): Oral acetazolamide may reduce subretinal fluid by altering fluid transport across the RPE and decreasing intraocular pressure in some settings. Typical dose is 250–500 mg twice daily, with monitoring for metabolic acidosis, kidney stones, and paresthesia. Evidence is limited and often adjunctive.AAFP

7. Anti-VEGF Plus Steroid Combination: In complex or refractory exudative detachments (e.g., from diabetic macular edema overlap), combining anti-VEGF with corticosteroids may yield better fluid resolution and visual outcome than monotherapy.PMCScienceDirect

8. Systemic Antibiotics/Antivirals (when infectious): If choroidal infection (e.g., tuberculosis, syphilis, or viral chorioretinitis) causes exudation, appropriate targeted antimicrobial therapy clears the infection and stops leakage. Choice and dose are pathogen-specific.AAFP

9. Systemic Anti-VEGF (rare/experimental): In select research contexts, systemic modulation of VEGF pathways has been explored; however, intravitreal remains standard. (Mentioned for completeness—evidence still emerging.)PMC

10. Adjunctive Diuretics (with caution): In some fluid-overload systemic states contributing to choroidal hydrostatic changes, careful use of systemic diuretics (e.g., low-dose furosemide) may be part of overall fluid management, but these are not primary therapy. Use only under physician guidance. (Inference from systemic fluid dynamics.)AAFP

Dietary Molecular Supplements

1. Lutein: Typical supplementation is 10–20 mg daily. Lutein accumulates in the macula, filters blue light, and acts as an antioxidant to reduce oxidative stress in retinal cells, supporting retinal structural integrity.PMCPMC

2. Zeaxanthin: Often paired with lutein (2 mg in AREDS2-type ratios). It serves similar protective roles, absorbing harmful light and quenching reactive oxygen species to prevent damage to retinal photoreceptors.PMCPMC

3. Omega-3 Fatty Acids (DHA/EPA): Common dose ranges from 500 mg to 1000 mg of combined EPA/DHA daily. They have anti-inflammatory effects, support retinal cell membrane health, and may improve choroidal circulation.PMCAmerican Osteopathic Association

4. Vitamin C (Ascorbic Acid): Doses around 500–1000 mg daily act as an antioxidant, regenerating other antioxidants and protecting ocular tissues from oxidative damage.PMCAmerican Osteopathic Association

5. Vitamin E (Tocopherol): Usually 400 IU in combination with other AREDS nutrients. It protects lipid membranes in retinal cells from oxidative injury.PMCPentaVision

6. Zinc: Common supplementation is 25–80 mg elemental zinc (often as zinc oxide) with copper to prevent deficiency. Zinc supports retinal pigment epithelium metabolic functions and antioxidant enzyme activity.PMCPentaVision

7. Copper: Added (typically 2 mg) when zinc is supplemented to avoid copper depletion; involved in antioxidant enzyme systems and connective tissue support in ocular structures.PentaVision

8. Astaxanthin: A carotenoid antioxidant with potential to reduce oxidative stress in ocular tissues; typical supplemental doses are 4–12 mg daily. It may help mitochondrial health in retinal cells. (Emerging evidence; more in degenerative contexts.)EatingWell

9. Curcumin (with enhanced bioavailability): Anti-inflammatory and antioxidant properties may help modulate low-grade inflammation contributing to retinal stress. Doses vary; formulations with improved absorption are preferred. (Evidence mostly preclinical/adjunctive.)PMC

10. N-Acetylcysteine (NAC): Precursor to glutathione, NAC supports intracellular antioxidant defense and may protect retinal cells under oxidative stress. Typical supplemental doses range 600–1200 mg daily. (Evidence is more experimental for retinal protection.)PMC

Note: These supplements are supportive for general retinal health and may assist recovery or prevention of damage; they are not primary treatments for active exudative detachment. Always coordinate supplements with a treating ophthalmologist to avoid interactions or inappropriate use.PentaVisionAmerican Osteopathic Association

Regenerative / Stem Cell / Advanced Immuno/Repair Therapies

1. Induced Pluripotent Stem Cell–Derived Retinal Pigment Epithelium (iPSC-RPE) Transplantation: In clinical trials, sheets or patches of RPE derived from a patient’s own iPSCs are transplanted under the retina to restore RPE function in chronic degenerative contexts. Early safety data are promising, with the aim of improving fluid handling and photoreceptor support.ophthalmologyscience.org

2. Human Embryonic Stem Cell–Derived RPE Patches: Trials are evaluating transplantation of RPE cells grown from embryonic stem cells on scaffolds to replace damaged RPE, potentially improving subretinal fluid dynamics when chronic RPE failure contributes to persistence.BioMed Central

3. Retinal Progenitor Cell Therapy: These are cells that can differentiate into retinal neurons; delivered intravitreally or subretinally in experimental settings to support retinal repair and possibly modulate local microenvironment.ScienceDirect

4. Mesenchymal Stem Cell (MSC) Intravitreal Injection: MSCs have paracrine anti-inflammatory and trophic effects; experimental use includes trying to stabilize retinal environment and promote healing in degenerative and inflammatory conditions. Safety and efficacy are still under investigation.PMC

5. CNTF-Releasing Implants (e.g., NT-501): Ciliary neurotrophic factor delivered via encapsulated cell implants is an example of a neuroprotective/regenerative approach aiming to bolster retinal cell survival under chronic stress, potentially improving long-term structural resilience.PMC

6. Autologous RPE Transplantation / Scaffold-Based RPE Replacement: Surgical placement of a patient’s own RPE or engineered RPE on scaffolds into the subretinal space is being studied to restore RPE pump function and reduce fluid accumulation in prolonged detachment scenarios.BioMed Central

Note: These advanced therapies are mostly in clinical trial phases or for chronic degenerative states; they are not standard first-line treatments for acute exudative retinal detachment, but represent future directions in regenerative retinal medicine.PMCPMCBioMed Central

Surgical / Procedural Treatments

1. Photodynamic Therapy (PDT): Used especially in chronic central serous chorioretinopathy to close leaking choroidal vessels and reduce subretinal fluid. A light-activated drug (verteporfin) is injected then activated by a laser to selectively target abnormal choroidal vasculature. This reduces leakage and helps the retina reattach.EyeWiki

2. Subretinal Fluid Drainage with Vitrectomy (when indicated): In complex or non-resolving cases where fluid persists or vision threatens, a vitrectomy with surgical drainage may be employed to remove the fluid and allow the retina to settle, often combined with addressing the underlying cause.AAFP

3. Sclerectomy / Scleral Thinning Procedures: In uveal effusion syndrome (a cause of exudative detachment due to abnormal scleral rigidity), surgical thinning of the sclera alleviates pressure and promotes normal fluid egress, helping the retina reattach.AAFP

4. Laser Photocoagulation of Focal Leaks: For localized leakage (such as in some CSR or Coats disease), applying laser to seal the leak can prevent further fluid accumulation and encourage reabsorption.EyeWikiSAGE Journals

5. Tumor Resection or Treatment (e.g., for Choroidal Melanoma): If a choroidal or subretinal tumor is causing exudation, direct treatment (surgical removal, plaque radiotherapy) reduces the source of leakage and allows the detachment to regress.EyeWikiScienceDirect

Preventions

Prevention focuses on controlling risk factors before detachment occurs. Maintaining normal blood pressure, managing autoimmune or inflammatory eye disease early, avoiding unnecessary corticosteroid exposure, quitting smoking, eating a retina-supportive diet, and having regular eye exams when at risk all lower the chance of exudative detachment. Early diagnosis and treatment of tumors, infections, or CSR also prevent fluid build-up. Educating patients to recognize warning signs ensures timely intervention.AAFPEatingWellEyeWikiAmerican Osteopathic Association

When to See a Doctor

You should seek immediate medical attention if you experience sudden floaters, flashes of light, a shadow or curtain over part of your vision, blurred or distorted vision, or any significant change in vision in one eye. These symptoms can signal an active detachment. If you have known inflammatory eye disease, hypertension with visual changes, or a tumor diagnosis and notice visual symptoms, prompt ophthalmologic evaluation reduces risk of permanent vision loss.Cleveland ClinicMayo Clinic

What to Eat and What to Avoid

Eat a diet rich in antioxidants and omega-3s: leafy greens (for lutein/zeaxanthin), fish high in DHA/EPA, citrus fruits (vitamin C), nuts and seeds (vitamin E, zinc), eggs, and colorful vegetables. These support retinal cell health, reduce oxidative stress, and help vascular function. Avoid excessive salt (to control blood pressure), processed foods that promote inflammation, smoking, and unnecessary corticosteroid use. Limiting high glycemic-load foods supports vascular integrity. Moderation of caffeine may be helpful in chronic CSR cases.Real SimpleEatingWellAmerican Osteopathic Association

Frequently Asked Questions (FAQs)

1. What is exudative retinal detachment?
   It is when fluid builds up under the retina without a tear, lifting it and distorting vision.NCBIEyeWiki

2. How is it different from other retinal detachments?
   Unlike tear-related (rhegmatogenous) or tractional detachments, exudative has no break—it’s due to leakage from underlying disease.AAFP

3. What causes the fluid to appear?
   Inflammation, tumors, choroidal vascular problems, high blood pressure, and central serous chorioretinopathy are main causes.EyeWikiScienceDirect

4. Can it heal on its own?
   Yes, if the underlying cause is treated and the detachment is mild, fluid can reabsorb and the retina can reattach.AAFP

5. When is surgery needed?
   If fluid persists, is large, caused by structural problems like uveal effusion, or arising from tumors, procedures such as sclerectomy, drainage, or laser may be needed.AAFPSAGE Journals

6. Do injections help?
   Yes. Anti-VEGF or steroid injections reduce leakage in many causes, especially when abnormal vessels or inflammation drive the detachment.BMJ OphthalmologyPMC

7. Are there pills for it?
   Some oral medicines like mineralocorticoid receptor antagonists (for chronic CSR) or systemic immunosuppressants (for inflammation) help address the cause.EyeWikiAAFP

8. Can diet make a difference?
   Eating antioxidant-rich foods and omega-3s supports retinal health and may help prevention, but diet alone usually doesn’t resolve active detachment.Real SimpleAmerican Osteopathic Association

9. Are supplements a cure?
   Supplements support eye health but are not cures for active detachment. They work best as part of a broader preventive or supportive plan.PentaVisionPMC

10. Is vision loss permanent?
    If treated early and the underlying cause controlled, vision often improves. Long-standing detachment may cause lasting damage.AAFP

11. Can it happen again?
    Yes, especially if the root cause (like chronic CSR or uncontrolled inflammation) recurs. Managing triggers reduces risk.EyeWiki

12. Is this an emergency?
    Significant sudden visual changes warrant prompt evaluation; delay increases risk of permanent impairment.Cleveland ClinicMayo Clinic

13. Do stem cell treatments work now?
    They are mostly experimental, under clinical trials, and not standard first-line care. Their goal is long-term retinal support or repair in chronic dysfunction.BioMed Centralophthalmologyscience.org

14. What are the risks of injections?
    Eye injections carry small risks of infection, increased eye pressure, and inflammation, but they are generally safe when done properly.BMJ Ophthalmology

15. How often should I get checked if I’m high risk?
    Frequency depends on the cause and severity; those with active inflammation or systemic risk often need monthly to quarterly check-ups until stable.AAFP
