Causes and Prognosis of Visual Acuity Loss at the Time of Initial Presentation in XXXX .

PURPOSE: To determine the etiology and prognosis of @entity227 in @entity5576 ( @entity5576 ) at presentation and to provide objective measures to predict visual outcome. METHODS: A retrospective review of 660 @entity1 with @entity5576 (2009-2013) identified 31 @entity1 (4.7%) with 48 eyes having best-corrected visual acuity (BCVA) of 20/25 or worse on initial presentation. Fundus photography, optical coherence tomography (OCT) of the optic disc and macula, and perimetry were used to determine the causes and prognosis of @entity1018 . Segmentation of the macula OCT was performed using the Iowa Reference Algorithm to determine the @entity989 . RESULTS: Outer retinal changes alone caused decreased BCVA at initial presentation in 22 eyes (46%): subretinal fluid in 16, chorioretinal folds in 5, and @entity1940 in 1. The @entity1018 was reversible except for some eyes with chorioretinal folds. @entity1781 alone caused decreased BCVA in 10 eyes (21%) and coexisting outer retinal changes and @entity1781 caused decreased BCVA in 16 eyes (33%). A GCL-IPL thickness less than or equal to 70  m at initial presentation or progressive thinning of greater than or equal to 10  m within 2 to 3 weeks compared with baseline correlated with poor visual outcome. CONCLUSIONS: Visual acuity loss in @entity5576 can be caused by both outer retinal changes and @entity1781 . @entity1018 from outer retinal changes is mostly reversible. The outcome of @entity1 with coexisting outer retinal changes and @entity1781 or @entity1781 alone depends on the degree of @entity1781 , which can be predicted by the GCL-IPL thickness.
