Changes in axial length before and after recovery in patients with idiopathic central serous chorioretinopathy with serous retinal detachment

Abstract

Purpose To evaluate the changes of axial length (AXL) in eyes with unilateral idiopathic central serous chorioretinopathy (CSC) after subretinal fluid absorption. Methods We studied 31 consecutive patients with unilateral resolved central serous chorioretinopathy. The keratometric value and AXL were measured by partial coherence interferometry (IOL Master®). Presence of subretinal fluid and central macular thickness (CMT) were measured by spectral domain optical coherence tomography (Cirrus HD OCT®). Results The mean age of 31 CSC patients was 42.7 years, and 19 males were included. The AXL was statistically significant difference from 23.41 to 23.58 mm after subretinal fluid absorption (p < 0.001). The differences in AXL correlated with CMT differences (r = −0.616, p < 0.001). Best corrected visual acuity and CMT were statistically significant difference after subretinal fluid absorption (p < 0.001). Conclusions In unilateral idiopathic CSC, the AXL was increased after subretinal fluid absorption. Therefore, the impact of serous retinal detachment should be considered in AXL measurement.
