Retina Surgery

Our retina clinic is fully equipped with newest generation of retina diagnostics such as Non- Mydriatic Fundus camera that captures the image of retina without the help of dilating drops & an OCT (Optical coherence tomography) that provides micron resolution scans of the retina.

Our Retina surgery centre is also equipped with Vitrectomy system, a BIOM and inverter system. For patients with Diabetic retinopathy, our medical retina clinic is equipped with Green LASER for control and treatment of diabetic retinopathy.

For macular edema, we provide intravitreal injections such as Avastin/ Leucentis/Aflibercept (Eylea). Macular edema is the build-up of fluid in the macula, i.e. the center of the retina. This fluid build-up causes the macula to swell and thicken, which distorts vision.

Diabetic Retinopathy

Diabetic Retinopathy

Diabetes affects blood vessels throughout the body, especially the retina. Due to diabetes, retina starts showing hemorrhages and this can lead to bleeding inside the eye, which is known as ‘vitreous hemorrhage’. The new blood vessels formed due to this can proliferate and reach the front part of the eye and lead to glaucoma or increase in eye pressure & leads to decrease in vision.

The treatment for diabetic retinopathy includes Lasers and intravitreal injections. We strongly recommend a strict watch over blood sugar to prevent Diabetic Retinopathy, as it will significantly reduce the long-term risk of vision loss. Treatment usually won't completely cure diabetic retinopathy nor will it restore normal vision, but it may slow the progression of vision loss. Without treatment, diabetic retinopathy progresses steadily from minimal to severe stages.

TREATMENT

This treatment is often recommended for people with macular edema, proliferative diabetic retinopathy (PDR) and neovascular glaucoma. Laser surgery shrinks abnormal new vessels and reduces macular swelling.

Laser surgery is usually performed in an office setting wherein the patient sits at an instrument called a slit-lamp microscope. A contact lens is temporarily placed on the eye in order to focus the laser light on the retina with pinpoint accuracy. With laser surgery for macular edema, tiny laser burns are applied near the macula to reduce fluid leakage. This treatment causes abnormal new vessels to shrink and often prevents them from growing in the future. It also decreases the chance that vitreous bleeding & is very effective for preventing severe vision loss. The main goal of treatment is to prevent further loss of vision by reducing the swelling of the macula.

Multiple laser treatments over time may be necessary. Laser surgery does not cure diabetic retinopathy and does not always prevent further loss of vision. It is uncommon for people who have blurred vision from macular edema to recover normal vision, although some may experience partial improvement.

FAQ's

Diabetic retinopathy is a condition in which high blood sugar causes retinal blood vessels to swell and leak blood.
Fluctuating blood sugar levels increase risk for this disease just like long-term diabetes. Most people don't develop diabetic retinopathy until they've had diabetes for at least 10 years. In this video, an eye doctor explains diabetic eye disease.

However, adult onset (type 2) diabetics should be evaluated at the time of diagnosis and every year thereafter, whereas juvenile onset (type 1) diabetics should be evaluated five years after diagnosis and every year thereafter, at a minimum.
Keeping your blood sugar at an even level can help prevent diabetic retinopathy. If you have high blood pressure, keeping that under control using the medicines & adopting a healthy lifestyle will be helpful.

Even controlled diabetes can lead to diabetic retinopathy, so you should have your eyes examined once every year; that way, your doctor can begin treating any retinal damage as soon as detected.
In the early stages of diabetic retinopathy, there may be no symptoms at all or slightly blurred vision. In the later stages, you develop cloudy vision, blind spots or floaters. But an assumption that good vision means all is well in the retina, is a major misconception and only invites trouble in future.
Diabetic retinopathy is classified as either non-proliferative (background) or proliferative. Non-proliferative retinopathy is the early stage, where small retinal blood vessels break and leak.

In proliferative retinopathy, new blood vessels grow abnormally within the retina. The new blood vessels may also grow or bleed into the vitreous humor, the transparent gel filling the back of the eye in front of the retina.

Proliferative retinopathy is much more serious than the non-proliferative form and can lead to total blindness.
No. Early treatment can slow the progression of diabetic retinopathy, but is not likely to reverse any vision loss.
The best treatment is to keep your diabetes & blood pressure under control.

Your doctor may decide on laser photocoagulation to cause regression of leaking blood vessels and prevent new blood vessel growth. If blood gets into the vitreous humor, your doctor might suggest ‘Vitrectomy’.
