#19
Ki Yup Nam, Jung Yeul Kim
SIGNIFICANCE: During the acute stage of central serous chorioretinopathy (CSC) with retinal elevation, the spectral domain optical coherence tomography (SD-OCT) estimate of ganglion cell layer complex thickness is reduced. Thickness returns to normal after resolution of the event. Measurement error is at least partially responsible for this effect. The reduction in ganglion cell layer complex thickness does not represent atrophy and is not predictive of a poor outcome. PURPOSE: We investigated the effects of serous retinal detachment on the ganglion cell layer complex analysis (GCA) by SD-OCT in CSC patients during the acute episodes and after resolution of fluid...
