Retinal Vascular Disorders

Hypertensive Retinopathy symptoms
Most cases of hypertensive retinopathy do not result in any symptoms. In a few severe cases, there may be vision loss or headaches.

Retinal Vein Occlusion (RVO) symptoms
The obstruction to the blood flow caused by an RVO, as well as associated complications such as macular swelling, may cause blurring of vision or visual loss. These symptoms range from mild to severe and can either occur suddenly or gradually over time. Bleeding from abnormal new vessels can cause floaters or blurring of vision. If glaucoma develops due to RVO, 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.

Retinal Artery Occlusion (RAO) symptoms
CRAO presents as a sudden, complete loss of vision in the affected eye. BRAO usually causes sudden loss of vision in part of the field of vision.
