Abstract
Posterior uveitis comprises a heterogeneous group of diseases with inflammatory alterations of the posterior fundus and is a common cause of visual impairment and blindness. The goal of this study was to evaluate the diagnostic value of wide-field fundus autofluorescence (FAF) in patients with non-infectious posterior uveitis and chorioretinal alterations. In this study 73 eyes from 51 patients were included. Best-corrected visual acuity, wide-field color and FAF images achieved by a wide-field scanning laser opththalmoscope (SLO, Optomap P200Tx, Optos PLC, Dunfermline UK) and a full ophthalmological examination were obtained from each patient. A systematic analysis of chorioretinal alterations detected with FAF and color images was conducted followed by the evaluation of the diagnostic information of wide-field FAF compared to the clinical finding and wide-field color images. Of the 73 eyes included in the study 52 showed peripheral alterations. In 32 cases wide-field FAF images revealed a greater number and more extensive chorioretinal alterations than the corresponding wide-field color images of the posterior fundus. In this study wide-field FAF images showed more chorioretinal alterations than seen in funduscopy or in color SLO images. Therefore, wide-field FAF images offer important additional information for detection and documentation of peripheral and central chorioretinal alterations.
