Purpose : To identify correlation initial and final visual acuity with changes of choroidal thickness.

Methods : We did retrospective clinical analysis on the macular ischemia using clinical record, fundus examination, optical coherence tomography and fluorescein angiography in 35 patients(35 eyes) who were diagnosed with retinal vein occlusion from January 2011 to December 2013 and were followed for over 6 months. We evaluated the extent and the location of macular ischemia, macular edema, choroidal thickness, initial and final visual acuity, and treatment. On fluorescein angiography which was performed within 2 weeks of the first visit. We analyzed changes of subfoveal choroidal thickness with Enhanced Depth Imaging of Spectralis HRA+OCT.

Results : RVOs consisted of 35 patients. Mean initial choroidal thickness showed 293.26±61.63um in RVO eyes, contrastively, 240.77±69.79um in fellow eyes. It shows statistically significant. 6 months later after treatment, choroidal thickness decreased to 251.94±63.85um but thicker than fellow eyes. Quantitative changes of initial and final choroidal thickness shows significant correlation with changes of central macular thickness(p=0.005). Difference of choroidal thickness between initial RVO eyes and fellow eyes showed negative correlation with final visual outcome(p=0.046).

Conclusions : It shows increased choroidal thickness at RVO eyes. There is significant correlation at quantitative difference between choroidal thickness of RVO eyes and fellow eyes with final visual outcome.
