Retina tomography after vitrectomy for macular edema of central retinal vein occlusion.
OBJECTIVE
To report retina tomography after vitrectomy for macular edema in central retinal vein occlusion (CRVO).


METHODS
Five patients with macular edema caused by CRVO were examined using optical coherence tomography (OCT) through their clinical courses.


RESULTS
The retinal thickness through the fixation was reduced in all 5 eyes. Preoperatively, the retina thickness at the foveola was more than 500 microm in three eyes and more than 1000 microm in 2 eyes. The retina thickness was reduced to 311+80 microm within two weeks on average. Visual acuity was improved by two or more lines in 3 of 5 eyes.


CONCLUSIONS
Vitrectomy is worthy of consideration when macular edemas are prolonged in patients of CRVO. OCT is a useful instrument for management and treatment of macular edema.
