Vision Loss

Retinal Artery Occlusion (RAO) is a serious eye condition that occurs when the blood flow to the retina is blocked due to a clot or narrowing of the arteries. This blockage deprives the retina of oxygen, leading to sudden and severe vision loss.

service

Causes:

Blood clots or embolism: Blockages from cholesterol, fat, or calcium deposits.

Atherosclerosis: Hardening of the arteries reduces blood flow.

High blood pressure: Increases the risk of artery damage.

Diabetes: Can lead to vascular complications affecting the retina.

Cardiovascular diseases: Conditions like heart disease or irregular heart rhythms.

Carotid artery disease: Narrowing of arteries supplying blood to the brain and eyes.

Glaucoma: Increased eye pressure may contribute to arterial blockage.

Symptoms:

service

Sudden and painless vision loss in one eye.

service

Blurred or dimmed vision.

service

Partial vision loss or a shadow in the visual field.

service

Loss of color vision.

service

Distorted or reduced ability to see fine details.

Treatment:

Hyperbaric Oxygen Therapy (HBOT): Increases oxygen delivery to the retina, promoting healing.

Medications: Blood thinners or clot-dissolving drugs to restore blood flow.

Ocular massage: Helps to dislodge the clot and improve circulation.

Lowering intraocular pressure: Using medications or procedures to reduce eye pressure.

Retinal laser treatment: In certain cases, lasers may be used to prevent complications.

Managing underlying conditions: Controlling diabetes, high blood pressure, and heart disease.

Prevention:

service

Manage blood pressure, cholesterol, and diabetes effectively.

service

Avoid smoking and excessive alcohol consumption.

service
