Abstract:
To evaluate the relationship between the morphologic changes of central serious chorioretinopathy ( CSCR) and recovery of visual acuity visual acuity ( VA) .METHODS: Thirty-eight eyes of thirty-eight patients with CSCR were studied and divided according to best corrected visual acuity (BCVA). Group 1, n=17 (45%), VA 6/6-6/9 (logMAR 0 ~0. 176); Group 2, n=19(50%), VA 6/9-6/18 ( logMAR 0. 176 ~ 0. 477 ); Group 3, n= 2 (5%), VA less than 6/18 (logMAR 0. 477). All patients inspected by spectral - domain optical coherence tomography ( SD-OCT) .RESULTS: The mean age of the patients was 42. 50 ± 5. 41years, the mean logMAR VA was 0. 176 ± 0. 0185, retinal pigment epithelium ( RPE) detachments in 21 eyes ( 55%) , including single RPE detachments in 14 eyes ( 67%) , and multiple confluent RPE detachments in 7 eyes (33%). Small bulge of RPE in 7 eyes (18%), granular deposition epi-RPE in 5 eyes (13%). The mean subretinal fluid height at the fovea was 259. 11 ± 128. 78μm. The average photoreceptor lengths were 70. 1 ± 9. 08μm, 81. 6 ± 8. 16μm, and 91. 9 ± 8. 03μm in groups 1, 2, and 3, respectively, the mean subretinal fluid height at the fovea was 66.5±8.13μm, 67.8±7.49μm, and 58.6±7.26μm after 6mo, respectively. The mean outer nuclear layer thickness during the active stage was 93. 10μm and it was 75. 69μm after 6mo (P=0. 012) CONCLUSlON: ln the acute CSCR, VA showed statistically significant association with greater dimensions of subretinal fluid-particularly, greater subretinal fluid height and thinning of the outer nuclear layer at the fovea. The type of pigment epithelium detachment ( PED ) , location, or fiber deposition has nothing to associate with VA. ln resolved CSCR, VA has a significant associated with a persistently thinner outer nuclear layer.
