Brief Summary
The purpose of this study is to correlate changes of visual function three weeks after photocoagulation for macular edema, with changes of center point thickness and macular volume.
Detailed Description
Photocoagulation for clinically significant macular edema is effective to reduce the incidence of moderate visual loss. Selective photocoagulation for focal macular edema statistically reduces macular...
