Comparison of 5-year progression of retinitis pigmentosa involving the posterior pole among siblings by means of SD-OCT: a retrospective study
Abstract Background The aim of this study is to analyze and compare the progression of photoreceptor atrophy among siblings affected by retinitis pigmentosa by means of spectral SD-OCT. Methods Fifty three eyes of 27 patients belonging to 12 family clusters were analyzed. To assess the annual progre...
