H34.23
Retinal artery branch occlusion
Clinical Classification Guidelines
Medical Intelligence & Overview
Retinal artery branch occlusion (RABO) is a condition where one of the small arteries supplying blood to the retina becomes blocked. The retina is a light-sensitive layer at the back of the eye that enables us to see by converting light into electrical signals sent to the brain. An occlusion in one of its branches can lead to sudden vision loss or visual disturbances in the affected area of the visual field. Recognizing this condition early is vital for managing symptoms and preventing further eye damage.
Causes & Symptoms
Clinical Causes: Atherosclerosis, which leads to buildup of fats and other substances in arteries Emboli, which are small traveling particles like cholesterol or blood clots that block the artery Cardiovascular diseases that promote clot formation High blood pressure (hypertension)
Key Symptoms: Sudden loss of vision in one part of the visual field Blurred vision or partial visual field defects Floaters or small spots in the visual field Visual field defects that might resemble a curtain or shadow
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination, including visual acuity testing and detailed imaging. Fluorescein angiography, an imaging technique that uses a special dye to visualize blood flow in the retinal vessels, is commonly performed. Optical coherence tomography (OCT) provides detailed images of the retina layers, aiding in identifying areas affected by ischemia or swelling. Prompt assessment by an eye specialist is essential to confirm the diagnosis.
Treatment Protocols: Laser therapy to treat ischemic areas Medications to control blood pressure, cholesterol, and blood sugar levels Use of antiplatelet or anticoagulant drugs to reduce the risk of clot formation Lifestyle changes like smoking cessation, healthy diet, and regular exercise
