Frequently asked questions

Purtscher retinopathy is a sudden eye condition where tiny blood vessels in the retina (the light-sensing layer at the back of the eye) become blocked and the inner retina loses oxygen. This usually happens after serious trauma to the head, chest, or long bones, but a very similar picture can also appear without trauma in certain medical illnesses—this non-traumatic form is called Purtscher-like retinopathy. On eye examination, doctors often see cotton-wool spots (small white fluffy patches), small retinal hemorrhages, and special polygon-shaped white patches called Purtscher flecken, which are considered highly characteristic. Many patients notice painless, sudden vision loss or blur, often within 24–48 hours of the triggering event, and both eyes are involved in many cases. The best-supported mechanism is tiny emboli and complement-driven white-cell clumps that block precapillary arterioles, causing inner retinal ischemia. NCBIEyeWiki

Types

Traumatic Purtscher retinopathy. This is the classic form that follows indirect trauma (for example, chest compression, severe head injury, or fractures). The retina shows cotton-wool spots, hemorrhages, and Purtscher flecken around the posterior pole. NCBI
Purtscher-like retinopathy (non-traumatic). The retinal picture is the same, but there is no direct trauma. It appears with systemic diseases such as acute pancreatitis, renal failure, preeclampsia/HELLP, autoimmune connective-tissue disease, thrombotic microangiopathies, and embolic events. EyeWikiNCBI
Laterality and tempo (useful clinical descriptors). The disease may be unilateral or bilateral (bilateral in roughly ~60% in many series) and the onset of visual symptoms is often within 24–48 hours of the trigger. Clinicians sometimes also describe severity by the area of ischemia and the level of macular involvement on imaging. EyeWikiNCBI

Causes

The first group follows trauma; the second group happens without trauma but produces the same retinal picture.

Severe head injury. A major head blow can trigger embolic and inflammatory changes that block small retinal arterioles and cause the typical whitening and cotton-wool spots. NCBI
Chest compression / crush to the thorax. Sudden pressure changes in chest veins and microembolization after a crush injury can injure the retinal microcirculation. NCBI
Long-bone fractures with fat embolism. Fat droplets released from bone marrow can contribute to capillary blockage in the retina after femur or other long-bone fractures. NCBI
Crush injuries or multi-system trauma. Large crush forces set off complement activation, white-cell aggregation, and microthrombosis in the eye. EyeWiki
Acute pancreatitis. Pancreatic enzymes and systemic inflammation can activate complement and promote emboli that occlude precapillary arterioles in the retina; bilaterality is common in this setting. EyeWikiPLOS
Chronic pancreatitis (acute flare). A flare can act like acute pancreatitis and cause the same retinal changes. NCBI
Pancreatic cancer. Pancreatic disease beyond pancreatitis has been linked to similar embolic/vasculitic mechanisms in Purtscher-like retinopathy. NCBI
Air embolism. Air entering the venous system (for example, in chest injuries) can disturb the retinal microvasculature and mimic the traumatic pattern. NCBI
Amniotic fluid embolism around childbirth. Delivery-related embolic and coagulation events can precipitate Purtscher-like changes with rapid vision loss. NCBI
Preeclampsia/eclampsia and hypertensive emergencies in pregnancy. Severe pregnancy-related hypertension and HELLP often accompany vaso-occlusive retinal disease that looks like Purtscher-like retinopathy. NCBI
HELLP syndrome. Hemolysis, elevated liver enzymes, and low platelets create a pro-thrombotic and ischemic milieu that can produce Purtscher-like lesions. NCBI
Acute or chronic renal failure; nephrotic syndrome. Uremia and microangiopathy in kidney disease are reported triggers of Purtscher-like retinopathy. NCBI
Acute renal allograft rejection. Severe immune activation and microvascular injury during rejection can present with Purtscher-like changes. NCBI
Systemic lupus erythematosus (SLE). Immune-complex and complement-driven retinal vascular occlusion in SLE can produce the same pattern of cotton-wool spots, hemorrhages, and Purtscher flecken. NCBI
Dermatomyositis / connective-tissue diseases / scleroderma. Systemic vasculitis and thrombotic microangiopathy can affect the retina in a Purtscher-like way. NCBI
Thrombotic microangiopathies (TTP/HUS and atypical HUS). Severe platelet consumption and capillary thrombosis can produce the Purtscher-like picture. NCBI
Cryoglobulinemia (often hepatitis C related). Cold-precipitable immune complexes can damage and block retinal microvessels. NCBI
Retrobulbar/peribulbar anesthesia or peri-orbital steroid injections. Particle or pressure effects around the orbit have been linked to Purtscher-like episodes. EyeWiki
Valsalva/weight-lifting/barotrauma; battered-baby syndrome. Sudden pressure shifts and venous congestion can produce the same retinal ischemic pattern. EyeWiki
Malignancy or treatments (e.g., chemotherapy-related thrombotic microangiopathy). Some cancers and oncologic therapies have been associated with a Purtscher-like vaso-occlusive retinopathy. NCBI

Common symptoms and signs

Sudden, painless vision loss or blurring. Vision changes often come on quickly, typically within 24–48 hours of the trigger. Pain is usually absent. NCBIEyeWiki
Vision is worse for central tasks. Reading and recognizing faces may be hard because the macula is often involved. EyeWiki
Central or paracentral blind spots. People may notice dark patches or missing areas near the center of vision (central or arcuate scotomas). EyeWiki
Bilateral symptoms are common. Many patients have both eyes affected, especially in pancreatitis-related cases. EyeWiki
Peripheral vision can be relatively spared. The problem often centers around the posterior pole (near the optic nerve and macula). EyeWiki
Reduced contrast or faded colors. Ischemia of inner retina can reduce contrast sensitivity and make colors look washed-out. NCBI
Metamorphopsia (distortion). Straight lines may look bent if the macula is edematous. EyeWiki
Floaters or small dots. Superficial hemorrhages can produce floaters in a few patients. EyeWiki
Normal-looking eye from the outside. The front of the eye may look normal; the findings are inside the eye on the retina. EyeWiki
Headache, chest pain, or abdominal pain from the trigger. These are not eye symptoms, but they can point to trauma, pancreatitis, or preeclampsia. NCBI
Light sensitivity can occur. It can happen with macular edema or inflammation. EyeWiki
No severe eye pain. Pain is not a hallmark feature unless another eye problem is present. NCBI
Variable visual acuity. Vision can range from near-normal to very poor depending on ischemia and macular involvement. PMC
Abnormal pupil reaction (RAPD) in worse eye. If one eye is much more affected, a relative afferent pupillary defect may be seen. NCBI
Findings your doctor sees: cotton-wool spots, retinal hemorrhages, optic disc edema, and Purtscher flecken—polygonal whitening with a clear perivascular rim about 50 µm wide. EyeWiki

Diagnostic tests

A) Physical exam

Best-corrected visual acuity (distance and near). This basic test measures how much vision is lost and helps monitor recovery. Sudden, painless acuity drop shortly after trauma or illness fits the condition. NCBI
Slit-lamp and anterior segment exam. The front of the eye is usually quiet, which helps focus attention on the retina as the main source of vision loss. EyeWiki
Intraocular pressure (applanation tonometry). Pressure is typically normal; checking it rules out other causes of vision loss that might raise the pressure. NCBI
Dilated fundus examination (biomicroscopy/indirect ophthalmoscopy). This is the key bedside exam: doctors look for cotton-wool spots, small hemorrhages, optic disc edema, and Purtscher flecken—polygonal areas of retinal whitening with a sharp, clear margin along vessels at the posterior pole. The flecken are highly characteristic. EyeWiki

B) Manual/bedside functional tests

Confrontation visual fields. Quick bedside mapping shows central or arcuate scotomas that match the posterior pole ischemia. EyeWiki
Swinging-flashlight (RAPD) test. A strong RAPD in one eye suggests more severe ischemia in that eye’s inner retina or optic nerve. NCBI
Amsler grid. A simple grid can reveal central distortion or small scotomas from macular ischemia or edema. EyeWiki
Photostress recovery time. Prolonged recovery can signal macular involvement, supporting the diagnosis when imaging is pending. EyeWiki

C) Laboratory & pathological tests

Serum amylase and lipase. These confirm or exclude acute pancreatitis, a major non-traumatic trigger; eye disease often appears within days of the abdominal event. NCBI
Complete blood count with platelets and smear. Thrombocytopenia or schistocytes point toward TTP/HUS or HELLP; leukocytosis may reflect trauma or pancreatitis. NCBI
Coagulation panel (PT/INR, aPTT), fibrinogen, and D-dimer. Abnormalities suggest DIC or a consumptive coagulopathy around childbirth or severe illness. NCBI
Renal panel and urinalysis (creatinine, BUN, proteinuria). These support acute/chronic renal failure, nephrotic syndrome, or preeclampsia-spectrum disease linked to Purtscher-like retinopathy. NCBI
Autoimmune serology (ANA, anti-dsDNA) and complement (C3/C4; C5 axis). These explore SLE/CTD and complement activation, which is central to the current pathophysiologic model. NCBIEyeWiki
ADAMTS13 activity (if TTP suspected) ± hemolysis labs (LDH, haptoglobin, bilirubin). These identify thrombotic microangiopathy, which is a recognized association. NCBI

D) Electrodiagnostic tests

Full-field electroretinogram (ffERG). In Purtscher disease, ERG may show reduced signals reflecting inner and outer retinal dysfunction from ischemia. EyeWiki
Multifocal ERG (mfERG). This maps macular function and often shows depressed A- and B-waves over the ischemic posterior pole; improvement can track clinical recovery. PubMed
Visual evoked potential (VEP). VEP can help when the functional loss seems disproportionate or when optic-pathway involvement needs exclusion; it complements ERG by testing post-retinal visual pathways. MDPI

E) Imaging tests

Optical coherence tomography (OCT). In the acute stage, OCT commonly shows inner-retinal hyperreflectivity (from ischemia), thickening, and macular edema; over time, outer-retinal thinning and photoreceptor loss may appear and correlate with prognosis. PAMM-pattern hyperreflectivity in the inner nuclear layer can be present. EyeWiki
Fluorescein angiography (FA). FA may show capillary non-perfusion, arteriolar occlusion, late leakage in ischemic areas, and sometimes disc leakage—findings that match the fundus signs and help exclude mimics. EyeWiki
OCT angiography (OCTA). OCTA can noninvasively reveal non-perfusion in the superficial and deep capillary plexus—even when FA looks near-normal—and is very useful for macular mapping and follow-up. PMCcanadianjournalofophthalmology.caBioMed Central

Non-pharmacological treatments (therapies & other measures)

These are supportive steps doctors may use alongside management of the underlying cause. They aim to protect remaining vision, reduce additional retinal stress, and help recovery. None of these are a guaranteed cure; they are part of comprehensive care.

Purpose: Attempt to improve oxygen delivery to ischemic inner retina.
Mechanism: Increases dissolved oxygen in plasma; evidence limited to case reports/series. PubMedPMC

Drug treatments

Important: There is no universally proven drug for Purtscher retinopathy itself. Most drugs below are used because of the underlying disease or for specific retinal complications like macular edema. Decisions are individualized by specialists. Evidence is largely case reports or small series unless noted.

High-dose IV methylprednisolone
Class: Corticosteroid.
Typical dosing/time: Common pulse regimens are 500–1000 mg IV daily for 3 days, then taper to oral steroids if indicated (specialist-directed).
Purpose: Dampen complement-driven leukocyte aggregation and endothelial inflammation.
Mechanism: Broad anti-inflammatory and anti-edema effects; may reduce leukostasis.
Side effects: Hyperglycemia, infection risk, mood changes, hypertension.
Evidence note: Reported benefit in some cases; not proven in controlled trials. PMCLippincott
Oral prednisone (taper)
Class: Corticosteroid.
Dose/time: e.g., 0.5–1 mg/kg/day tapered over weeks if a steroid course is chosen after IV pulses or for milder disease; specialist-guided.
Purpose/mechanism/side effects: As above.
Evidence: Mixed; used pragmatically in some series. PMC
Intravitreal anti-VEGF (bevacizumab or similar) when macular edema is present
Class: Anti-VEGF biologic.
Dose/time: Typical intravitreal dosing schedules (e.g., 1.25 mg bevacizumab), repeated per retina specialist.
Purpose: Reduce macular edema and vascular leakage that can follow ischemia.
Mechanism: VEGF blockade decreases permeability and edema.
Side effects: Rare endophthalmitis, IOP spikes.

Intravitreal triamcinolone (selected cases)
Class: Corticosteroid injection.
Dose/time: 1–4 mg intravitreal; schedule individualized.
Purpose: Treat persistent macular edema.
Mechanism: Local anti-inflammatory/anti-edema effect.
Side effects: Cataract progression, ocular hypertension, infection risk.
Evidence: Small case reports only. SCIRP
Hyperbaric oxygen as a procedure (not a drug), often protocolized like a therapy
Rationale: Included here because it is delivered in “treatment sessions” and reported in ophthalmic ischemia.
Purpose/mechanism: Increase oxygen to the inner retina while microcirculation recovers.
Evidence: Case reports suggest potential benefit in selected patients. PubMed
Eculizumab for atypical hemolytic uremic syndrome (aHUS)–associated Purtscher-like retinopathy
Class: Complement C5 inhibitor.
Dose/time: Standard aHUS regimen (IV, specialist protocol).
Purpose: Switch off uncontrolled complement activation driving systemic and ocular microangiopathy.
Mechanism: Blocks C5 cleavage; reduces C5a/C5b-9–mediated injury and leukocyte aggregation.
Side effects: Serious meningococcal infection risk—vaccination/prophylaxis required.
Evidence: Case reports show systemic response with anatomical retinal improvement in aHUS-related cases. PMCSAGE Journals
Systemic immunosuppression for autoimmune triggers (e.g., lupus)
Class: Depending on disease—high-dose steroids, sometimes cyclophosphamide, mycophenolate, or rituximab per rheumatology.
Purpose: Control the autoimmune flare causing Purtscher-like changes.
Mechanism: Reduces immune-mediated endothelial injury and microthrombosis.
Side effects: Drug-specific (infection, cytopenias, gonadotoxicity for cyclophosphamide).
Evidence: Disease-directed, not specific to Purtscher; used when a flare is confirmed. EyeWiki
Antiplatelet therapy (e.g., low-dose aspirin) when a vascular risk profile warrants it
Class: Antiplatelet.
Purpose: Secondary vascular risk reduction under medical supervision.
Mechanism: Inhibits platelet aggregation systemically; theoretical microvascular benefit.
Side effects: Bleeding, dyspepsia.
Evidence: No Purtscher-specific trial; considered for systemic indications only.
Plasma exchange for TTP/aHUS if indicated by hematology
Class: Apheresis therapy.
Purpose: Remove pathogenic factors in thrombotic microangiopathies.
Mechanism: Clears autoantibodies/ultra-large vWF multimers in TTP; adjunct before targeted therapy.
Evidence: For the systemic disease; ocular findings may improve as the TMA resolves. Oxford Academic
Hemorheologic agents (e.g., pentoxifylline) — experimental in this context
Class: Microcirculatory flow improver.
Purpose/mechanism: Increase erythrocyte flexibility, reduce blood viscosity; theoretical aid to microflow.
Evidence: Only scattered reports; not standard of care. Side effects include nausea, dizziness. PubMed

Bottom line on drugs: The only consistently evidence-based “treatment” is correct diagnosis and aggressive management of the underlying trigger. Eye-directed pharmacologic steps are individualized and guided by a retina specialist; many cases improve as the precipitating illness resolves. PMC+1

Dietary molecular supplements

These may support overall retinal and vascular health. Always review supplements with your clinicians—interactions and contraindications are possible, especially after trauma, surgery, or when using immunotherapy/anticoagulants.

Omega-3 fatty acids (EPA/DHA) – e.g., 1–2 g/day combined EPA+DHA with meals
Function: Anti-inflammatory, endothelial support.
Mechanism: Resolvin pathways reduce inflammatory mediators in microvasculature.
Lutein & Zeaxanthin – 10 mg lutein + 2 mg zeaxanthin/day
Function: Macular pigment support and antioxidant effect.
Mechanism: Quenches reactive oxygen species in inner retina.
Vitamin C – 500–1000 mg/day in divided doses
Function: Collagen and capillary support; antioxidant.
Mechanism: Scavenges free radicals in ischemic tissue.
Vitamin E (natural mixed tocopherols) – 100–200 IU/day
Function: Lipid membrane antioxidant.
Mechanism: Limits peroxidation in retinal cells.
Zinc (as zinc gluconate or citrate) – 10–25 mg elemental/day
Function: Cofactor in antioxidant enzymes.
Mechanism: Supports retinal enzyme systems.
B-complex (with B6, B12, folate) – Balanced B-complex daily
Function: Homocysteine metabolism and neurotrophic support.
Mechanism: Helps endothelial health and nerve function.
Coenzyme Q10 – 100–200 mg/day with fat-containing meal
Function: Mitochondrial energy support.
Mechanism: Electron transport and antioxidant action.
Alpha-lipoic acid – 300–600 mg/day
Function: Redox cycling antioxidant; supports microvascular function.
Mechanism: Regenerates other antioxidants; improves endothelial nitric oxide bioavailability.
N-acetylcysteine (NAC) – 600 mg 1–2×/day
Function: Glutathione precursor; mucolytic benefits if respiratory issues coexist.
Mechanism: Increases intracellular glutathione—key for oxidative stress defenses.
Curcumin (with piperine or phytosome form) – 500–1000 mg/day standardized extract
Function: Systemic anti-inflammatory support.
Mechanism: Down-regulates NF-κB–mediated cytokines.

Note: These are general supportive doses for adults. They do not replace medical care and have variable evidence for Purtscher retinopathy specifically.

Regenerative / stem-cell drugs

There are no approved stem-cell or “immunity booster” drugs to treat Purtscher retinopathy. Proposing unregulated stem-cell products or immune-stimulant drugs for this condition would be unsafe. What is used in carefully selected situations is targeted immune modulation for a proven systemic disease (e.g., eculizumab for aHUS) and, rarely, local ocular therapies for macular edema. Below are safe, evidence-aware categories your doctors may consider only when indicated by the underlying diagnosis:

Eculizumab (C5 inhibitor) for aHUS-related disease – specialist protocol
Function: Shut down pathologic complement activity.
Mechanism: Blocks C5 cleavage; reduces leukocyte aggregation and endothelial damage. PMC
Ravulizumab (long-acting C5 inhibitor) for aHUS – specialist protocol
Function/mechanism: As above, with longer dosing interval.
Caution: Vaccine prophylaxis needed (meningococcal).
Systemic immunosuppression for autoimmune triggers (e.g., high-dose steroids ± cyclophosphamide in severe lupus vasculitis)
Function: Control the flare that precipitates retinal microangiopathy.
Mechanism: Decreases immune-mediated endothelial injury. EyeWiki
Plasma exchange for TTP (disease-directed)
Function: Remove pathogenic factors driving microthrombi.
Mechanism: Clears autoantibodies/UL-vWF, improving microcirculation. Oxford Academic
Intravitreal anti-VEGF for macular edema
Function: Reduce retinal edema and leakage.
Mechanism: VEGF blockade stabilizes the blood–retina barrier. PMC
Intravitreal steroid (triamcinolone) for persistent edema
Function/mechanism: Local anti-inflammatory; reduces edema when VEGF blockers are unsuitable. SCIRP

If you see online claims about stem-cell injections “curing” Purtscher retinopathy, be skeptical. Such uses are experimental and not approved.

Surgeries/procedures

Eye surgery is not a standard treatment because the core problem is microvascular and often improves as the trigger is treated. Procedures are reserved for uncommon complications:

Intravitreal injection (anti-VEGF or steroid)
Procedure: In-office sterile injection into the vitreous cavity.
Why it’s done: To treat visually significant macular edema or persistent leakage. PMC
Pars plana vitrectomy
Procedure: Operating-room surgery to remove vitreous gel.
Why it’s done: Rarely, if non-clearing vitreous hemorrhage or tractional issues develop and obscure vision.
Panretinal photocoagulation (PRP)
Procedure: Laser treatment to the peripheral retina.
Why it’s done: Only if ischemia sparks neovascularization (uncommon in Purtscher retinopathy).
Focal/grid laser for chronic focal leakage
Procedure: Precisely targeted retinal laser.
Why it’s done: Occasionally considered if a focal leaking point persists and anatomy suits laser.
Systemic surgeries (non-ocular) for the trigger
Procedure: For example, cholecystectomy in gallstone pancreatitis or fracture fixation after trauma.
Why it’s done: Removing the underlying source reduces ongoing systemic injury that threatens the retina. PMC

Preventions

Reduce trauma risk: Seatbelts, workplace protection, sports eye protection.
Address pancreatitis risks: Limit alcohol, manage gallstones with your clinician, maintain healthy triglycerides. PMC
Control blood pressure and diabetes: Protect retinal microvessels.
Stop smoking: Improves endothelial health.
Healthy weight and lipid control: Lowers systemic inflammation.
Manage autoimmune disease proactively: Keep up with rheumatology care to prevent flares. EyeWiki
Follow surgery/childbirth precautions if previously affected: Inform your team of any past Purtscher-like episode.
Avoid sudden heavy Valsalva early after an episode: Reduce venous spikes.
Medication safety: Use anticoagulants/antiplatelets only when prescribed; avoid unproven “blood thinners.”
Regular eye checks if high risk: Early detection after major trauma or pancreatitis.

When to see a doctor

Immediately (same day) if you notice sudden blurred vision, dark spots, or a curtain-like shadow—especially within days after trauma, pancreatitis, major surgery, childbirth, or a known autoimmune flare.
Urgently if you develop new floaters, flashes, or sudden worsening of vision after a recent Purtscher episode.
Promptly if you have systemic symptoms—severe abdominal pain (possible pancreatitis), uncontrolled blood pressure, or features of a clotting/complement disorder—and vision changes. PMCEyeWiki

What to eat” and “what to avoid

Diet does not cure Purtscher retinopathy, but it can support recovery and help prevent systemic triggers, especially pancreatitis or vascular stress.

Eat more of:

Low-fat, whole foods (lean proteins, legumes, whole grains) to reduce post-prandial lipemia.
Colorful vegetables & fruits (lutein, zeaxanthin, vitamin C).
Omega-3-rich fish (salmon, sardine) 2× per week.
Nuts and seeds (walnut, flax, chia) in modest portions.
Plenty of water to maintain hydration and blood rheology.

Avoid or limit:

Alcohol, especially after pancreatitis—major relapse risk.
Very high-fat meals that stimulate pancreatic lipase surges.
Trans fats and ultra-processed foods that worsen endothelial function.
Excess salt and sugar if you have hypertension or diabetes.
Smoking (not food, but crucial lifestyle avoidance).

Frequently asked questions

Is Purtscher retinopathy the same as Purtscher-like retinopathy?
They look the same in the eye. “Purtscher” usually follows trauma; “Purtscher-like” follows non-traumatic illnesses such as pancreatitis or autoimmune disease. PMC
What exactly causes the white patches (Purtscher flecken)?
They are areas of inner retinal whitening from tiny blood vessel blockages and ischemia near the posterior pole, often with a clear zone around arterioles. bhm.scholasticahq.com
What is the main mechanism?
Abnormal complement activation leads to clumping of white blood cells (leuko-embolization) that plug small retinal arterioles; fat/air emboli and endothelial injury may contribute. NCBIPubMed
Can it affect both eyes?
Yes—about half of patients have both eyes involved. PLOS
Will my vision recover?
Many patients see partial improvement over weeks to months, especially if the trigger is treated quickly. Prognosis varies with severity and macular involvement. PMCPLOS
Are steroids a cure?
No. Some reports suggest benefit; others show recovery without steroids. There are no definitive trials. PMCbhm.scholasticahq.com
When do you use anti-VEGF injections?
When there is significant macular edema or persistent leakage on OCT/angiography, a retina specialist may consider an intravitreal anti-VEGF. PMC
What about hyperbaric oxygen?
It has been reported as a rescue option in severe ischemia, but evidence is limited to case reports. PubMed
Could complement blockers help?
In aHUS-related Purtscher-like retinopathy, eculizumab has improved the systemic disease and ocular anatomy in case reports. It is not a general treatment for all patients. PMC
Is laser surgery normally needed?
No. Laser is considered only if rare neovascularization develops. Most cases do not need ocular surgery.
Can this recur?
It can, if a similar triggering event happens again. Preventing the triggers lowers the chance.
Is it contagious?
No.
Should I change my diet?
Adopt a heart-healthy, low-fat pattern and avoid alcohol if pancreatitis was involved—this helps your overall recovery and reduces future risk.
How is the diagnosis confirmed?
By history (recent trauma or illness) plus eye exam and imaging (OCT; sometimes angiography) showing cotton-wool spots, hemorrhages, and Purtscher flecken. EyeWiki
What follow-up do I need?
Typically frequent visits early on (weeks) with OCT, then less often as the retina stabilizes—timing individualized by your retina specialist.
