Purpose and objective: To report retina tomography after vitrectomy for macular edema in central retinal vein occlusion (CRVO).
Patients and 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.
Conclusion: 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.
