H34.03

Clinical Causes: Atherosclerosis, which involves the buildup of fatty deposits in blood vessels Emboli, or debris, traveling from larger arteries to the small arteries supplying the retina Cardiovascular diseases that may lead to blood clots or other blockages Blood disorders that increase clot formation Sudden changes in blood pressure Vasospasm, or sudden constriction of the retinal arteries Inflammation of blood vessels (vasculitis) Other circulatory system abnormalities

Key Symptoms: Sudden, painless loss of vision in both eyes Brief episodes of visual impairment that resolve quickly Partial visual field loss Visual disturbances such as blurred vision or flickering lights Possible sensation of shadow or curtain descending over the visual field

Diagnosis Path: To diagnose transient bilateral retinal artery occlusion, healthcare providers typically conduct a comprehensive eye examination, including visual acuity tests and fundoscopic (retinal) examinations. Additional assessments may involve imaging tests such as fluorescein angiography, which visualizes blood flow in the retinal vessels, and carotid Doppler ultrasound to evaluate blood flow in neck arteries. Blood tests are often performed to assess clotting factors, lipid levels, and other cardiovascular risk factors.

Treatment Protocols: While the condition is transient and may resolve on its own, medical management focuses on preventing future episodes and addressing underlying causes. Treatment strategies may include antiplatelet or anticoagulant medications, management of cholesterol levels, blood pressure control, and lifestyle modifications like smoking cessation, regular exercise, and a healthy diet. In some cases, surgical or minimally invasive procedures may be considered to remove blockages or repair blood vessels. Immediate treatment aims to restore normal blood flow and minimize potential for permanent retinal damage.
