Central Retinal Vein Occlusion (CRVO)
Central retinal vein occlusion is a blockage of the main vein that drains blood from the retina. It typically causes sudden, painless blurring of vision in one eye.

About central retinal vein occlusion (crvo)
What to know
The retina becomes swollen with bleeding, and fluid collects at the macula, which reduces central vision. Diagnosis uses a dilated eye examination, optical coherence tomography (OCT) scanning and sometimes fluorescein angiography. It is linked to high blood pressure, diabetes, glaucoma and high cholesterol, so a general health check is needed.
Anti-VEGF eye injections such as ranibizumab (Lucentis) or aflibercept (Eylea) reduce macular swelling and often improve vision, but repeated injections are usually needed. Steroid implants are an alternative, and laser treatment may be used if abnormal new vessels form. Controlling blood pressure, diabetes and cholesterol is essential. Treatment abroad is sometimes considered for a retina service offering regular injections.
Pre-flight workup
Tests to have already done
- Retinal OCT scans showing macular swelling thickness, and fluorescein angiography to check blood flow and ischaemia.
- Vision (acuity) measurements and fundus photographs with dates, and eye pressure readings.
- Medical history for causes: blood pressure, diabetes, cholesterol and blood clotting disorders, with recent blood results.
- Records of any injections or laser given, with dates, drug used and response.
- A list of general medicines, including blood thinners, and any glaucoma history.
Second opinion
When to get a second look
- Your vision has dropped suddenly and you have not yet had an urgent retinal assessment.
- Injections have not improved the swelling after several doses, and you want to know about other drugs or implants.
- Scans show ischaemic CRVO or new blood vessels, which need monitoring or laser.
Talking to your doctor
Questions to ask
- Is my occlusion ischaemic or non-ischaemic, and what does that mean for my vision?
- How many injections will I need, and how often will I be monitored?
- Which drug is best for me, and are there alternatives such as steroid implants?
- What systemic tests should be done to look for causes?
- What signs would need urgent review, such as pain or new floaters?
Outlook
Realistic prognosis
Anti-VEGF injections reduce swelling and improve or stabilise vision in most patients, but they are often needed monthly at first and then at longer intervals for a year or more. Outcome depends on vision at the start, the degree of ischaemia and how early treatment begins. Ischaemic types may develop new vessels or glaucoma and have a poorer visual outlook.

Diagnostic workup
Before you pick a hospital, get the workup right
Picking the right treatment is downstream of a complete diagnosis. Skip steps here and the destination surgeon usually re-orders them anyway — at higher cost and another week on the ground.
- Confirm the diagnosis on imaging or labs
For central retinal vein occlusion (crvo), plan on the workup your home doctor would order anyway — typically a recent specialist consult plus the imaging / labs the destination team will need to quote accurately. Anything older than 90 days usually gets re-done.
- See a ophthalmology specialist locally first
An in-person clinical exam at home — even a single consult — costs little and dramatically improves the destination plan. Bring back: written impression, recommended procedure, surgical-risk class, and any contra-indications.
- Send us the file for a free second opinion
Two surgeons in our medical panel review the workup independently. They tell you whether they'd operate, watch, or refer — even if that means recommending against travel.
- Pick a path with timeline + cost in writing
Once a treatment is the right call, we line up 2–3 hospital options with itemized quotes, surgeon profiles, and a travel timeline. You hold the file — switch hospitals or step away at any point.

04 · FAQ
Common questions about central retinal vein occlusion (crvo)
Will my vision recover?
It improves in many patients with injections, but the extent varies. Vision at the start and the degree of ischaemia strongly affect the outcome.
How many injections will I need?
Often monthly at first, then spaced according to scans. Many patients need treatment for a year or longer, and some need ongoing injections.
Can it affect my other eye?
There is a modest risk of an occlusion in the other eye, mainly linked to blood pressure, diabetes, cholesterol and glaucoma, so control of these matters.
Can I fly after an injection?
Usually yes after a short period if the eye is comfortable. Your eye doctor will check for pressure or infection first.
Clinical context
Working up central retinal vein occlusion (crvo) properly
A condition like central retinal vein occlusion (crvo) is rarely well-served by jumping straight to treatment shopping. The sequence below is what a ophthalmology specialist would expect to see completed — and the absence of any step is the right cue to delay travel decisions.
Diagnostic workup, in sequence
- First-line clinical assessment
History, physical exam, and risk-factor review by a senior generalist or ophthalmology specialist. Symptoms list, family history, prior workup notes, and current medication list should travel with the patient.
- Standard imaging + labs
Baseline blood work, condition-specific imaging (ultrasound / X-ray / MRI / CT — depending on indication), and ECG / pulmonary function as relevant. Bring digital copies of any prior imaging — saves repeat scans and the cost that goes with them.
- Specialist diagnostic workup
Procedure-specific tests — biopsy, cardiac catheterisation, endoscopy, or genetic / molecular profiling depending on the suspected diagnosis. Done at the centre that will treat, ideally, so results integrate cleanly into the treatment plan.
- Multidisciplinary review (where indicated)
Cancer, complex cardiac, transplant, and rare-disease cases should be reviewed by a multidisciplinary panel — surgical, medical, imaging, and pathology — before any treatment commits. Single-discipline plans for complex disease are a quality red flag.
When to escalate urgently
- Acute worsening of established symptoms — sudden chest pain, shortness of breath at rest, neurological deficit, severe bleeding, persistent high fever.
- Loss of consciousness, severe persistent vomiting, or any focal neurological event.
- Symptoms in the early hours of onset that fit a time-sensitive treatment window (stroke, MI, sepsis) — every hour costs outcome.
- If you are travelling internationally for treatment and develop these symptoms in transit, divert to the nearest emergency department; do not wait to reach the planned destination.
Before you book international travel
- Confirm your specific diagnosis is fully worked up before you commit to a treatment plan abroad. Travelling for the workup is fine; travelling for treatment without the workup done is not.
- Get your case reviewed remotely by the destination centre's team before you book flights — credible international patient programs review imaging + reports before they confirm the surgical plan.
- Bring a digital + physical copy of your full medical record: imaging on USB drive in DICOM format, labs in PDF, current medication list with dosages, allergies, and any prior surgical reports.
- Plan for the post-op rehabilitation phase before you fly — the surgery itself is rarely the bottleneck.
- Confirm that follow-up imaging and any necessary in-person reviews can be done at home — a treatment plan that requires repeat international trips is more burdensome (and more expensive) than the headline procedure.
