The film at the back of the eye
Think of the eye as a camera: the retina is the film. Light falls on it, and the optic nerve carries the picture to the brain. The centre of the retina, the macula, gives sharp reading vision.
Damage to the retina often starts without pain or blur. Found early, most of it can be treated and sight protected.
What we see most often
Diabetic retinopathy
High sugar damages the small blood vessels of the retina; they leak or bleed.
Blood pressure and the eye
Long-standing high BP narrows retinal vessels and can cause bleeding or swelling.
Floaters and flashes
Specks or cobwebs that drift across vision; usually harmless, sometimes a warning.
Retinal detachment
The retina lifts away from the back of the eye. An emergency — needs treatment within days.
Macular problems
Age-related changes or swelling at the centre: straight lines look wavy, reading gets hard.
Often none at first
Diabetic and BP damage usually gives no warning until late. If you have diabetes, have your retina checked once a year — even if you see well.
a sudden shower of new floaters, flashes of light, or a dark curtain or shadow over part of your vision. These can mean the retina is tearing or detaching.
Call +91 94164 79792How the retina is checked
Dilated eye check
Drops widen the pupil so the doctor can see the whole retina. Vision is blurry for a few hours — bring someone to drive.
OCT scan
A painless scan that shows the layers of the retina and any swelling, on our Huvitz OCT.
Your sugar and BP
Bring your latest sugar (HbA1c) and BP readings — they shape the plan.
Treatment depends on the cause
Control sugar and BP
The base of all retina care: it slows damage in both eyes.
Laser
Seals leaking vessels or weak areas of the retina. Done in the clinic.
Eye injections
Medicine placed inside the eye to reduce swelling at the centre of the retina.
Dr. Swati explains which treatment suits your eye, and refers to a retina surgeon when an operation is needed.
Questions patients ask us
I have diabetes but see well. Do I still need a check?
Yes, once a year. Retina damage from diabetes is usually silent until it is advanced.
Are floaters dangerous?
Most old floaters are harmless. A sudden increase, with flashes or a shadow, needs a same-day check.
Can I drive after the dilated check?
Better not for a few hours. Bring someone with you.
