Definition / Overview
An occlusive vasculopathy of the retina occurring after exposure to ionizing radiation (external beam or plaque brachytherapy). Resembles diabetic retinopathy clinically. Mentioned in the RAM article as a secondary cause of macroaneurysm.
Key Details
- Details to be added from dedicated source â dose thresholds, latency period, clinical features, management
- Can cause secondary retinal-arterial-macroaneurysm formation
Clinical Relevance
Should be considered as a secondary cause when evaluating a patient with RAM who has a history of radiation therapy (especially head/neck or ocular tumors).
Associations
- retinal-arterial-macroaneurysm â secondary cause
- diabetic-retinopathy â similar clinical appearance
