Retina Condition

Retinal Vein Occlusion

Retinal vein occlusion (RVO) — a blockage in one of the veins that drains blood from the retina — can cause sudden, painless blurring in one eye, and it needs a retina specialist quickly. Our fellowship-trained retina team treats both branch (BRVO) and central (CRVO) vein occlusion with OCT and angiography-guided diagnosis, anti-VEGF injections, targeted retinal laser and, where suitable, intravitreal steroids.

Overview

What is Retinal Vein Occlusion?

The retina is the light-sensitive layer at the back of your eye, and it relies on tiny veins to carry blood away from it. Retinal vein occlusion happens when one of those veins becomes blocked — usually by a blood clot, or by narrowing linked to conditions like high blood pressure or diabetes. When the vein is blocked, blood and fluid back up into the retina. That leakage causes macular edema (swelling of the macula, the central part of the retina you read and recognise faces with), which is the main reason vision drops in RVO.

RVO is not rare. It is the second most common retinal vascular disorder after diabetic eye disease, and it becomes more common with age. It is closely tied to blood-pressure, blood-sugar and cholesterol control — which is why treating the eye and reviewing your general health go hand in hand.

Because the vision loss is usually painless and in one eye, many people notice it only when they happen to cover the other eye. If your sight has changed suddenly, our retina treatment team can assess you the same week — early review gives the eye its best chance.

~16 million

people worldwide are affected by retinal vein occlusion — the second most common retinal vascular disorder after diabetic eye disease.

Rogers et al., pooled analysis, Ophthalmology, 2010.

Types

Types of RVO:

RVO is grouped by where the blockage sits and how much of the retina it starves of blood flow. Which type you have shapes the treatment plan and what to expect.

TypeWhat it meansIn practice
Branch RVO (BRVO)A blockage in a smaller branch vein — affects part of the retina.The more common form; often a better visual outlook when the macula is treated early.
Central RVO (CRVO)A blockage in the main retinal vein — affects the whole retina.Tends to cause more marked vision change; needs close monitoring.
Non-ischemic (either type)Milder — leaky vessels with macular swelling, blood flow largely preserved.Usually treated with injections to control swelling.
Ischemic (either type)More severe — small vessels close off, retina is starved of oxygen.Higher risk of new abnormal vessels and glaucoma; may need laser.
~80%

of vein occlusions are the branch form, according to international data — and Indian hospital data report a similar pattern.

Song et al., systematic review, Journal of Global Health, 2019.

A non-ischemic RVO can turn ischemic over time, so even a ‘mild’ occlusion is worth reviewing regularly. Scheduled scans tell us which way your eye is heading — long before you would notice the difference yourself.

Symptoms

Symptoms of Retinal Vein Occlusion:

RVO usually affects one eye and comes on without pain. See a retina specialist promptly if you notice any of these — which of them sounds like you?

Sudden blurring or a drop in vision in one eye, often noticed on waking.

A dark, grey or missing patch in part of your field of vision.

Distorted vision — straight lines look bent or wavy (a sign of macular swelling).

New floaters, or a sudden shower of spots (can signal bleeding inside the eye).

Vision that fluctuates — clearer at some times, blurrier at others.

Sudden vision loss should always be checked quickly — book a comprehensive eye examination rather than waiting to see if it settles.

When to seek urgent care

Don’t Wait On These

Pain and redness are not typical early on. If they appear later, they can point to raised eye pressure and need urgent attention. A sudden drop in vision in one eye should be examined the same day wherever possible.

Diagnosis

Diagnosis:

RVO is often recognisable the moment a retina specialist examines the back of your eye, but confirming the type and measuring the swelling guides the whole treatment plan.

These scans are repeated over the treatment course so we can see, objectively, whether the swelling is settling — not guess. Distinguishing RVO from look-alike conditions such as diabetic retinopathy is part of this assessment.

02

Optical Coherence Tomography (OCT)

A quick, non-invasive scan that maps and measures macular swelling and tracks your response to treatment.

03

Fluorescein Angiography (FFA)

A dye study that shows which vessels are leaking or closed, and whether the occlusion is ischemic.

Eye-Pressure & General-Health Review

Including blood pressure, blood sugar and cholesterol, because RVO is often the eye’s warning sign of a wider vascular issue.

Treatment

Treatment Options:

The goal of treatment is to control the macular swelling that reduces vision and to protect the eye from complications. RVO is managed, not switched off in a single step — but with timely, structured treatment many patients regain useful vision. Our retina team tailors the plan to your type of RVO, how much swelling is present and your general health.

First-line for macular swelling

Anti-VEGF Injections

Anti-VEGF medicines (such as ranibizumab, aflibercept and bevacizumab) are injected into the eye to reduce leakage and swelling. These are treatment averages, not a promise for any one eye — your outcome depends on the type and severity of your RVO and how early treatment starts.

Injections are given after numbing drops, so most patients feel pressure rather than sharp pain. RVO usually needs a series of injections over months — sometimes longer — with OCT scans guiding how many. Anti-VEGF reduces swelling but does not ‘cure’ the blocked vein, which is why regular follow-up matters (American Society of Retina Specialists).

55–61%

of branch-RVO patients gained at least three lines of vision at six months with monthly ranibizumab, versus about 29% on a sham injection.

46–48%

of central-RVO patients gained three or more lines, versus roughly 17% on sham.

BRAVO and CRUISE trials, Ophthalmology, 2010.

Retinal Laser

Where the retina is ischemic and starts to grow abnormal, fragile vessels, targeted laser (including pan-retinal photocoagulation) helps calm that response and lowers the risk of bleeding and a difficult form of glaucoma. Laser may be used alongside injections rather than instead of them.

Intravitreal Steroids

For selected patients, a steroid injection or a slow-release steroid implant (such as dexamethasone) is an alternative way to control stubborn swelling. Because steroids can raise eye pressure or speed cataract formation, we choose them case by case and monitor closely.

Treating underlying causes is part of the plan too — good control of blood pressure, diabetes and cholesterol supports the eye and lowers the chance of the other eye being affected. Where nutrition plays a supporting role in retinal health, we may also discuss eye nutrition treatment. Not every eye responds the same way; if a different retinal condition is contributing, we will guide you to the right treatment.

Consult with our doctors

Individual results vary. Suitability, benefits and risks depend on the type and severity of your occlusion, how much swelling is present and your overall health, and can only be determined after a detailed examination with our doctors.

Protecting Your Sight

Prevention and Risk Management:

You cannot always prevent RVO, but you can lower your risk and protect your second eye by managing the vascular factors behind it:

Keep blood pressure well controlled — hypertension is the single biggest modifiable risk factor for RVO.

Manage diabetes and keep blood sugar in your target range.

Control cholesterol and follow a heart-healthy routine — regular activity, no smoking.

Have regular eye checks if you have glaucoma or a family history of eye disease.

Report any sudden change in vision straight away — early treatment protects sight.

Whole-Person Care

Managing Underlying Conditions:

RVO is often the eye’s early signal of a wider circulation problem, so treating the eye is only half the job. We work alongside your physician to review blood pressure, blood sugar and cholesterol, and we recommend a general medical check after diagnosis — especially if both eyes are involved, where clotting tendencies are more likely and further tests may be advised (American Society of Retina Specialists).

Managing these conditions well supports your treated eye and helps safeguard the other. Our retina specialists also monitor for related retinal disease such as Diabetic Retinopathy and Age-related Macular Degeneration (AMD), which can coexist and affect the plan.

FAQs

Frequently Asked Questions

The questions patients ask us most about retinal vein occlusion. For anything specific to your eye, a consultation gives the clearest answer.

Often, some vision can be recovered — especially when macular swelling is treated early. In clinical trials many RVO patients gained three or more lines of vision with anti-VEGF injections. Recovery varies from eye to eye and depends on the type and severity of the occlusion, so the honest answer comes after we examine your eye. Early treatment gives the best chance.

There’s no fixed number. RVO usually needs a series of injections over months, with OCT scans guiding how many and how often. Some eyes settle after a few; others need ongoing treatment. We review your response at each visit and adjust the plan.

The eye is numbed with drops first, so most patients feel pressure rather than sharp pain. The injection itself takes only a moment, and you go home the same day.

RVO is managed rather than ‘cured’ — treatment controls the swelling and protects the eye, but the blocked vein itself doesn’t simply reopen. With timely, regular care, the aim is to recover and preserve as much useful vision as possible.

Most often, yes — high blood pressure is the biggest risk factor, and diabetes and high cholesterol also contribute. That’s why we recommend a general medical check after diagnosis and work with your physician to control these, which also helps protect your other eye.

Urgent. Sudden vision change should be seen quickly. Most patients can avoid severe vision loss if treatment starts before lasting damage develops, so please don’t wait to see if it settles on its own.

It can, particularly if the underlying vascular risks aren’t controlled. Managing blood pressure, blood sugar and cholesterol well is the best way to lower that risk — and we’ll monitor both eyes.

Anti-VEGF injections start from around ₹25,000 each, with laser and scans additional; overall retina treatment commonly ranges from ₹25,000 to ₹80,000+ per eye depending on your condition and how many injections are needed. These are indicative starting-from figures, confirmed after your consultation. Easy EMI and cashless insurance options are available.
