A retrospective review was performed on 176 eyes from 114 patients with nonexudative AMD who visited the Department of Ophthalmology at the Asan Medical Center from November 2010 to September 2012. The design of this study followed the principles of the Declaration of Helsinki. All patients underwent a comprehensive ophthalmologic examination, including best-corrected visual acuity (BCVA), fundus examination, color fundus photography, FA, ICGA, FAF, and SD-OCT. Fluorescein angiography, ICGA, and FAF images were acquired using a Heidelberg Retina Angiograph 2 (HRA2; Heidelberg Engineering, Heidelberg, Germany) and SD-OCT imaging was performed using Spectralis system software (version 1.7.0.0; Heidelberg Engineering). Enhanced depth imaging optical coherence tomography was also performed on all eyes. Patients were excluded if they had a refractive error (RE) of 3 diopters (D) or higher, the presence or a past history of choroidal neovascularization, a history of any other retinal diseases, or a history of any retinal surgery. Pseudophakic patients with an unknown preoperative RE were also excluded as were patients with eyes showing a significant media opacity where good quality OCT scans or FAF images could not be attained.
