6 eye conditions you never knew could be caused by high blood pressure
Doctor reveals 6 silent eye problems that are triggered by high BP. Don’t wait until it’s too late.
People usually associate high blood pressure with heart attacks or strokes but few realise it can silently damage their vision too. From minor vision blurring to sudden eye strokes, hypertension can have serious consequences on ocular health that often go unnoticed until they become permanent.

In an interview with HT Lifestyle, Dr Priyanka Singh (MBBS, MS, DNB, FAICO), Consultant and Eye Surgeon at Neytra Eye Centre in New Delhi, emphasized the lesser known yet critical link between blood pressure and eye health. She revealed how elevated BP levels can impact your vision -
1. Blurred or fluctuating vision
High BP can affect the delicate blood vessels of retina, leading to a condition called hypertensive retinopathy. This results in visual disturbances such as blurriness, black spots, or even flashes of light. It often develops silently and is only detected during routine eye exams.
2. Risk of retinal vein occlusion (eye stroke)
When blood pressure is consistently high, it increases the risk of a blockage in the veins of the retina leading to the sudden vision loss in one eye, commonly known as eye stroke. This condition is painless. But can be devastating if not treated promptly.
3. Recurrent haemorrhage in the eye

While subconjunctival hemorrhages may appear as a red patch and are often harmless, retinal hemorrhages can severely affect vision and maybe warning sign of advanced hypertensive damage

Some studies suggest a link between high blood pressure and increased intraocular pressure, which may contribute to glaucoma-a silent disease that gradually reduces peripheral vision without symptom in its early stages.
6. Early detection and prevention
Routine eye check-ups can be life-saving as ophthalmologist often detect early signs of systematic disease like hypertension during retinal exams, regular monitoring of BP, reducing salt intake, exercising and avoiding smoking can protect both heart and eye health.
“We often talk about how hypertension affects the heart and kidney but many people forget that eyes are equally vulnerable. High blood pressure can silently damage the tiny blood vessels in the retina and lead to sudden vision loss,” said Dr Priyanka Singh
Even minor vision changes should not be ignored, especially if you are living with high blood pressure. A simple eye exam can be first clue to much larger problem and possibly save your sight.
