Identification of anastomosis between the central retinal artery and the central retinal vein in a case of central retinal vein occlusion due to arteriovenous malformation.
OBJECTIVE
To report the identification of an arteriovenous anastomosis over the optic nerve head in a case of arteriovenous malformation.


METHODS
Dynamic scanning laser angiography was performed in a 12 year old girl with a severe arteriovenous malformation complicated by central retinal vein occlusion.


RESULTS
The presence of an arteriovenous anastomosis between the central retinal artery and vein was identified. This anastomosis later regressed completely.


CONCLUSIONS
An arteriovenous anastomosis between central vessels within the optic nerve may be a cause of central retinal vein occlusion. Spontaneous regression of the anastomoses may lead to improvement of fundus features.
