(a) Color fundus photograph of the left eye showing a large aberrant branch of a dilated superotemporal vein reaching up to the fovea (congenital retinal macrovessel). The inferotemporal vessels are attenuated. (b) Fluorescein angiogram showing multiple arteriovenous communications around the CRM. Horizontal (c) and vertical (d) SD-OCT scans through the macula showing marked thinning of the macula inferiorly especially involving the inner retinal layers. A macular thickness map (e) confirms that the superior quadrant is unaffected
