Optic nerve sheath decompression for progressive central retinal vein occlusion.
OBJECTIVE
To review our results with optic nerve sheath decompression (ONSD) for progressive central retinal vein occlusions (CRVO).


METHODS
Patients selected all had evidence of progressively worsening CRVO, a component of optic nerve swelling, and most were already monocular from prior disease in the contralateral eye. ONSD was performed using a nasal approach under retrobulbar anesthesia.


RESULTS
Eight eyes from 8 patients with a mean follow-up of 12 months were analyzed. Six patients improved, 2 worsened. Mean preoperative visual acuity was 20/160, and mean final postoperative visual acuity was 20/70. No complications occurred. Nonischemic CRVOs, patients < 65 years old, and those undergoing ONSD within 3 months of presentation seemed to do better.


CONCLUSIONS
ONSD may improve vision or stabilize visual loss in patients with progressive CRVO.
