Fluorescein angiography (FA) is a useful examination in patients suffering from diabetic retinopathy (DR). Traditional angiograms explore 30°-50° of the retina at once; however, visualization of peripheral retina is fundamental in order to assess nonperfused areas, vascular leakage, microvascular abnormalities, and neovascularizations. In order to expand the field of view, wide-field and ultra-...

 ABSTRACT The purpose of this study was the evaluation of cycloplegic effect of homatropine 2% on central corneal curvature and power. 43 volunteers who participated in the study were examined. Thirty-nine of them (28 men and 11 women) which had normal eyes with visual acuity of 20/20 and a mean age of 29.6 ± 6.7 years were selected. Then corneal topography was performed on both eyes. After per...
