What is Retina Surgery?

Retina Surgery in India: A Growing Demand

The retina is the thin, light-sensitive sheet lining the back of the eye. Every image you have ever seen has been built there, photon by photon, before being sent to the brain. When it works, you never think about it. When it tears, detaches, fills with blood, or swells with fluid, the consequences can be dramatic and, without treatment, often permanent.

Retina surgery is the specialised branch of ophthalmology that deals with diseases of the retina, the vitreous gel that fills the eye behind the lens, and the macula (the central part of the retina responsible for sharp central vision). Retina surgeons repair retinal detachments, clear vitreous haemorrhages, treat diabetic retinopathy, close macular holes, and manage a long list of conditions that would otherwise end in severe visual loss.

At Vasan Eye Care, retina services are delivered by fellowship-trained vitreoretinal surgeons using modern diagnostic imaging platforms and microsurgical instrumentation. Treatment plans are built around each patient’s specific pathology, with the aim of restoring or preserving as much vision as the eye will allow.

The burden of retinal disease in India has grown substantially, driven by three converging forces. First, the diabetes epidemic: India has one of the largest diabetic populations in the world, and diabetic retinopathy affects a large proportion of patients with long-standing diabetes. Second, an ageing population, which brings age-related macular degeneration and retinal vascular events. Third, a growing awareness of conditions that used to go undiagnosed and untreated, thanks to wider screening and better imaging.

Indian tertiary eye care centres now provide the full range of retinal services: laser photocoagulation, intravitreal injections, scleral buckling, pneumatic retinopexy, and pars plana vitrectomy. Modern imaging tools (optical coherence tomography, OCT angiography, ultra-wide-field fundus photography, and B-scan ultrasonography) make early detection and precise surgical planning possible in ways that were not available a decade ago.

Vasan Eye Care follows evidence-based protocols aligned with guidelines from the All India Ophthalmological Society, the Vitreo-Retinal Society of India, and international bodies such as the American Academy of Ophthalmology.

Types of Retina Surgery Available in India

Retina Surgery – How the Procedures Work?

The approach depends on what the eye needs. Vitrectomy involves removing the vitreous gel through three tiny ports placed in the pars plana, which gives the surgeon access to the retina, membranes, and posterior segment. From there, the surgeon can peel membranes, treat detachments, remove blood, and apply laser or gas tamponade as required.

Scleral buckling uses a silicone band placed around the outside of the eye to gently indent the sclera, bringing the detached retina back into contact with the underlying layers. Pneumatic retinopexy uses an expandable gas bubble to close a retinal tear from inside the eye, without opening anything. Laser photocoagulation seals retinal tears or treats abnormal new vessels caused by ischaemia. Intravitreal injections deliver medication directly into the vitreous cavity for macular disease.

Each technique is chosen based on the nature, location, and extent of the retinal pathology. No single surgery fits all retinal disease. Knowing which tool to use (and when) is what separates experienced retinal surgeons from everyone else.

When Is Retina Surgery Necessary? Signs to Watch For

Retinal pathology often presents with visual symptoms that are either sudden and alarming or quietly progressive. Warrant urgent ophthalmic review for any of the following:

• A sudden shower of new floaters
• Flashes of light, particularly in the peripheral vision
• A dark curtain or shadow spreading across the field of vision
• Sudden reduction in vision
• Distortion of straight lines (metamorphopsia)
• A central dark spot or grey area in the visual field

Patients with diabetes or high blood pressure should undergo routine retinal screening even in the absence of symptoms. Retinal detachment, macular hole, and vitreous haemorrhage are common indications for surgery. Diabetic macular oedema and age-related macular degeneration are typically managed with intravitreal injections and laser rather than a full operation.

Step-by-Step: A Typical Retinal Surgical Pathway

• Comprehensive retinal evaluation: dilated fundus examination, OCT, fundus photography, fluorescein angiography and B-scan ultrasound where relevant.
• Pre-operative counselling: diagnosis, proposed procedure, expected outcomes, and risks discussed openly.
• On the day of surgery: admission, anaesthesia (usually peribulbar block or general), eye prepared and draped.
• Microsurgical ports placed; the planned intervention performed; tamponade (gas or silicone oil) applied if required.
• Ports closed, antibiotic and anti-inflammatory drops started, patient monitored for a few hours before discharge.
• Post-operative follow-up, including specific positioning if a gas bubble is used, strictly adhered to.

How Much Does Retina Surgery Cost in India?

Costs vary widely with the procedure, gauge of instrumentation, use of tamponade, and hospital category. Indicative figures:

Post-Surgery Care and Recovery

What to Expect After Retina Surgery?

Recovery varies with the procedure. After vitrectomy with gas tamponade, vision is typically blurred until the gas absorbs over two to six weeks. When silicone oil is used, vision improves after the oil is removed, usually at three to six months. Mild redness, watering, and a foreign body sensation are common in the first week. Strict positioning (such as a face-down posture) may be required after certain procedures like macular hole surgery, and it is not a suggestion. It is part of the treatment.

Post-Operative Care Tips

• Follow every positioning instruction carefully. Improper posture can compromise surgical success in procedures that depend on tamponade.
• Use prescribed drops on schedule.
• Do not fly while gas tamponade is in the eye. Altitude-related expansion can raise intraocular pressure dangerously.
• Avoid heavy lifting, bending, and strenuous exercise for two to four weeks.
• Protect the eye from dust and water during healing.
• Attend every follow-up. These visits check retinal reattachment, intraocular pressure, and overall recovery.
