Retinal Detachment

Overview

A retinal detachment occurs when the retina — the light-sensing layer lining the back of the eye — separates from the wall of the eye that nourishes it. Because a detached retina rapidly loses function, this is a sight-threatening emergency that usually requires prompt surgery to reattach it and preserve vision.

Most detachments are rhegmatogenous, meaning they start with a tear or hole in the retina — often from age-related shrinkage of the vitreous gel — that lets fluid seep underneath and lift the retina. Less commonly, scar tissue (as in advanced diabetes) pulls the retina off, or fluid builds up beneath it from inflammation or other causes.

Repair is highly effective at reattaching the retina, but final vision depends on the type of detachment and whether the central macula was affected. This page is an educational overview only — it is not medical advice, and no outcome can be guaranteed.

Who May Need This

Surgery is needed by anyone with a confirmed retinal detachment, and urgent assessment is needed by anyone with its warning symptoms — new floaters, flashes, or a curtain over the vision. Certain people are at higher risk: those who are highly short-sighted (myopic), have had previous eye surgery or injury, have a family history of detachment, or have already had a detachment in the other eye.

A retinal tear without detachment can sometimes be sealed with laser or freezing in the clinic to prevent progression. A vitreoretinal surgeon examines the retina to determine the type and extent of the problem and the appropriate treatment.

When It May Be Recommended

Repair is recommended as soon as a detachment is diagnosed, often within hours to a few days. Timing is especially critical when the macula (the centre of vision) is still attached, because operating before it detaches gives the best chance of preserving sharp central vision.

Even when the macula has already detached, timely surgery is still advised to reattach the retina and give the best achievable outcome. The urgency, and the exact technique, depend on the location, size, and cause of the detachment, and are decided by the specialist.

Diagnosis and Evaluation

Diagnosis is made by a dilated retinal examination, in which the surgeon inspects the whole retina to locate tears and the extent of detachment. Optical coherence tomography (OCT) assesses the macula, and ultrasound is used when bleeding or a cataract blocks the view of the retina.

The surgeon evaluates the type of detachment, the state of the lens and vitreous, and general health, including diabetes where relevant. Because positioning and flying restrictions may follow surgery, and because time matters, evaluation and treatment are often arranged urgently.

Treatment Options

Treatment depends on the detachment. A simple retinal tear without much fluid may be sealed with laser or cryotherapy (freezing) to prevent detachment. For established detachments, options include pneumatic retinopexy (a gas bubble plus laser or freezing, for selected cases), scleral buckling (a silicone band that indents the eye wall), and vitrectomy (removing the vitreous and using gas or silicone oil to hold the retina).

These techniques are sometimes combined, for example vitrectomy with a buckle. Traction detachments from diabetes usually need vitrectomy. The surgeon selects the method most likely to reattach the retina based on its type, size, and location.

How It Is Performed

In scleral buckling, a soft silicone band is stitched around the outside of the eye to gently indent the wall inward so it meets the detached retina, and tears are sealed with freezing or laser; fluid under the retina may be drained. In vitrectomy, the surgeon removes the vitreous through tiny ports, drains the sub-retinal fluid, applies endolaser around tears, and fills the eye with a gas bubble or silicone oil to press the retina flat while it heals.

Pneumatic retinopexy is a less invasive office- or theatre-based procedure in which a gas bubble is injected and the patient positions the head so the bubble tamponades the tear, with laser or freezing to seal it. Surgery is usually done under local anaesthesia with sedation, occasionally general anaesthesia.

Preparation

Because detachment repair is often urgent, preparation may be rapid: the team confirms the diagnosis, checks general health and medications (including blood thinners), and arranges anaesthesia. Discuss the likely head-positioning requirements and flying restrictions so you can plan recovery and travel.

If care is being arranged abroad, remember that timing is critical and local emergency treatment may be needed first. Bring your retinal records and scans, allow enough in-country time for a gas bubble to absorb before flying, and arrange for help during recovery.

Benefits and Expected Goals

The goal of surgery is to reattach the retina, seal the tears, and preserve as much vision as possible. Surgery reattaches the retina in a high proportion of cases, sometimes after more than one procedure, which is the essential first step toward saving sight.

The visual outcome depends heavily on whether the macula had detached and for how long. If the macula stayed attached, vision is often well preserved; if it had detached, some blur or distortion may remain despite successful reattachment. Your surgeon can explain the realistic outlook for your eye.

Risks and Possible Complications

Retinal detachment surgery is generally successful but carries real risks.

• Failure of the retina to reattach or re-detachment, needing further surgery
• Scar tissue formation on the retina (proliferative vitreoretinopathy) reducing success
• Cataract formation or progression, especially after vitrectomy
• Raised eye pressure, particularly with a gas bubble or silicone oil
• Bleeding or infection inside the eye
• Double vision or discomfort after a scleral buckle
• Incomplete visual recovery even after successful reattachment

Your surgeon will explain the risks specific to your detachment and technique. Report increasing pain, worsening vision, or a new curtain in your sight promptly.

Recovery, Follow-up & Aftercare

After surgery the eye is usually red and sore, and vision is blurry, particularly if a gas bubble is present, which appears as a moving line until it absorbs over weeks. You will use antibiotic and anti-inflammatory drops as directed and may need to maintain a specific head position for several days so the bubble supports the retina.

Avoid heavy lifting, strenuous activity, and eye rubbing as advised, and do not fly or go to high altitude while a gas bubble remains. Vision improves gradually over weeks to months. Attend all follow-up visits so the retina and eye pressure can be monitored, and arrange this care with a retinal specialist at home before returning.

Medical Tourism Planning

Retinal detachment is time-critical, so urgent local care usually comes first; planned travel is more relevant for follow-up surgery, oil removal, or non-urgent tears. If arranging care abroad, choose a JCI- or ISO-accredited hospital with a vitreoretinal service and an experienced retinal surgeon.

Ask which technique and tamponade are planned, what positioning will be needed, and when you can fly home, allowing enough time for a gas bubble to absorb. Arrange continuing retinal care at home, request a written treatment plan and cost estimate, and consider medical travel insurance.

Estimated Cost Factors

The cost of retinal detachment repair depends on the country and hospital, the surgeon’s fees, the technique used (buckle, vitrectomy, or pneumatic retinopexy) and whether they are combined, the use of gas or silicone oil (oil needs a later removal operation), anaesthesia, and follow-up. Complex or repeat surgery adds cost, as can a longer stay for a gas bubble to absorb.

Many destinations offer retinal surgery at a fraction of typical US prices, but figures vary widely and online prices are only estimates. Always request a personalized written quote that specifies the technique and any second-stage oil removal before deciding.

Choosing a Hospital or Specialist

Look for an accredited hospital with a vitreoretinal unit and a fellowship-trained vitreoretinal surgeon experienced in detachment repair, ideally with capacity for urgent surgery. Ask about their reattachment success rates if available and how re-detachments and complications are handled.

Confirm the imaging and emergency arrangements and what international patient services and follow-up are offered. Transparent written pricing and a clear discussion of positioning, flying restrictions, and realistic vision outcomes are signs of a quality centre.

Alternatives

For a retinal tear or hole without detachment, laser or cryotherapy in the clinic can often prevent progression and avoid major surgery. Once the retina has detached, however, there is no effective non-surgical treatment, and the choice is between the surgical techniques (buckle, vitrectomy, or pneumatic retinopexy).

Delaying treatment risks permanent vision loss, so prompt care is essential. Discuss which surgical approach best suits your detachment, and the trade-offs of each, with a vitreoretinal specialist.
