H34.213
Partial retinal artery occlusion, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Partial retinal artery occlusion affecting both eyes is a rare condition where blood flow is blocked in the small arteries supplying the retina, leading to partial vision impairment in each eye. The retina is the light-sensitive layer of tissue at the back of the eye crucial for visual perception. When blood flow is compromised, it can result in vision disturbances, which may be temporary or permanent if not promptly addressed. This condition is classified under ICD-10 code H34.213 and requires careful medical evaluation to determine underlying causes and appropriate management strategies.
Causes & Symptoms
Clinical Causes: Emboli or clots originating from the heart or large arteries that travel to the retinal arteries. Atherosclerosis, leading to narrowing and hardening of arteries supplying the eyes. Vasculitis, inflammation of the blood vessels in the retina. Blood hyperviscosity syndromes, making blood thicker and reducing flow. Cardiovascular conditions such as atrial fibrillation which predispose to embolic events. Giant cell arteritis or temporal arteritis, causing inflammation and blockage of blood vessels. Trauma to the head or neck leading to vascular injury.
Key Symptoms: Sudden onset of visual field loss or blurred vision in one or both eyes. Partial loss of vision rather than complete blindness. Short duration of symptoms if the occlusion is transient. Possible visual disturbances such as floaters or flashes. In some cases, no pain is experienced, which can make the event less noticeable.
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination and medical history review. Key diagnostic tools include:
Treatment Protocols: The primary goal of treatment is to restore retinal blood flow and prevent permanent vision loss. Interventions depend on the underlying cause and timing of presentation:
