Arteriolar macroaneurysm on the optic disk associated with branch retinal vein occlusion.
OBJECTIVE
To report a case of an arteriolar macroaneurysm on the optic disk associated with branch retinal vein occlusion (BRVO).


METHODS
Patient chart review.


METHODS
An 80-year-old man presented with a retinal arteriolar macroaneurysm on the optic disk on the root of a papillomacular vein, which caused BRVO.


RESULTS
Eight months later, the macroaneurysm shrank spontaneously and became fibrous tissue. The hemorrhage and edema due to BRVO resolved.


CONCLUSIONS
We speculate that the macroaneurysm was located on and compressed the epipapillary portion of the papillomacular vein, resulting in BRVO. With spontaneous involution of the macroaneurysm, the compression resolved, and the clinical findings improved.
