Retinal Vascular Disorders

Hypertensive Retinopathy symptoms
There are few obvious symptoms of hypertensive retinopathy, but in some cases, there is vision loss or headaches.

Retinal Vein Occlusion (RVO) symptoms
The obstruction to the blood flow in the optic nerve by an RVO may cause blurring of vision or visual loss. These symptoms range from mild to severe and can either occur suddenly or gradually over time. In some cases, there might be pain and blindness in the affected eye.

Because of the threat to vision, regular eye examinations are important to pick up the problem early. An eye examination for RVO usually includes a range of vision tests to check vision accuracy and some investigations to study the eye itself and the presence of swelling or blockages.

Central Retinal Artery Occlusion (CRAO) symptoms
CRAO presents as a sudden loss of vision in the affected eye.
