Just like high water pressure can burst a pipe, High Blood Pressure (Hypertension) damages the tiny, delicate blood vessels inside your eyes. This condition is called Hypertensive Retinopathy.

Early detection is the only cure.
How Does BP Damage the Eye?
Think of your eye's retina like a camera film. It needs a steady supply of blood.
When your Blood Pressure stays high (above 140/90) for a long time, the walls of the eye's blood vessels thicken to handle the pressure. Eventually, they become narrow or stiff.
The result? Blood cannot reach the retina properly, or the vessels burst (hemorrhage), causing vision loss.
4 Risks You Cannot Ignore
🩸
Retinal Bleeding
Small blood vessels burst inside the eye. You might see red patches or dark floating spots (floaters) in your vision.
🌑
Eye Stroke (Occlusion)
Just like a brain stroke, a clot can block an eye vein. This causes sudden, painless loss of vision in one eye. This is an emergency.
🔍
Macular Edema
Fluid leaks into the 'Macula' (the center of your vision). Things will look blurry, wavy, or distorted (straight lines look bent).
⚡
Optic Nerve Damage
High BP cuts off blood to the optic nerve (the cable connecting eye to brain). This can kill nerve cells and cause permanent blindness.
Warning Signs: When to see a Doctor?
Note: In early stages, there are NO symptoms. That is why routine checkups are vital.
Blurry Vision: Hard to focus while reading or watching TV.
Floaters: Seeing black spots or "mosquito-like" shapes flying in front of eyes.
Dim Vision: Feeling like lights are dimmer than usual.
Headaches: Specifically morning headaches with eye pain.
Sudden Vision Loss: Often happens upon waking up (Eye Stroke).
How We Treat It at SGVEH
Dr. Charudutt Kalamkar uses advanced AIIMS-standard protocols to save your vision.
01
Fundus Photography
We take a high-resolution photo of your retina to see leaking vessels.
02
OCT Scan
Like an MRI for the eye. It shows us swelling (fluid) inside the retinal layers.
03
Injections / Laser
If there is swelling or bleeding, we use Anti-VEGF injections or Green Laser to stop the leakage immediately.
Patient Questions (FAQs)
My vision is perfect. Do I still have damage?
Yes, possibly. BP damage starts at the outer edges of the retina where you don't notice it. By the time it affects your central vision (blurriness), the damage is already advanced. Diabetic and BP patients must get a checkup every 6 months.
Can glasses fix vision loss from High BP?
No. Glasses only fix focus issues. High BP damages the "film" (retina) inside. If the film is damaged, changing the lens (glasses) won't help. You need medical retinal treatment.
Is the vision loss permanent?
If caught early (swelling/bleeding), we can restore much of the vision using injections. However, if the Optic Nerve strokes out (dies due to lack of blood), that vision cannot be recovered. Time is critical.
What is an "Eye Stroke"?
It is a sudden blockage of the retinal vein or artery. It usually happens to people with uncontrolled BP. If you suddenly lose vision in one eye, come to the hospital immediately (within 4 hours) for the best chance of recovery.
