Abstract

PURPOSE
To evaluate the changes of axial length (AXL) in eyes with unilateral idiopathic central serous chorioretinopathy (CSC) after resolution of serous retinal detachment.
METHODS
A total of 31 patients diagnosed with idiopathic unilateral CSC were included in this study. The changes of AXL according to serous retinal detachment were examined. The keratometric value and AXL were measured using partial coherence interferometry. Serous retinal detachment and central macular thickness (CMT) were measured by spectral domain optical coherence tomography.
RESULTS
The mean age of the 31 CSC patients, including 19 males, was 42.7 years. The AXL was significantly increased from 23.41 to 23.58 mm after resolution of serous retinal detachment (p < 0.001). The CMT was significantly decreased from 413.4 to 226.8 µm after resolution of serous retinal detachment (p < 0.001). The differences in AXL correlated with CMT differences and subretinal fluid height (r = −0.616, p < 0.001 and r = −0.637, p < 0.001, respectively), and the best-corrected visual acuity was significantly different after resolution of serous retinal detachment (p < 0.001).
CONCLUSIONS
In unilateral idiopathic CSC with serous retinal detachment, a shortened AXL in the acute phase was restored after resolution of serous retinal detachment.

  Fig. 1 Representative optical coherence tomography images of a patient with serous macular elevation with left central serous chorioretinopathy. (A) The central macular thickness was 491 µm, and the axial length measured by partial coherence interferometry was 23.31 mm in the presence of serous retinal detachment; (B) the central macular thickness decreased to 240 µm and the axial length increased to 23.75 mm after resolution of serous retinal detachment. ILM-RPE = internal limiting membrane retinal pigment epithelium; AL = axial length; SD = standard deviation; SNR = signal-to-noise ratio; K1 = flat keratometric value; D = diopters; K2 = steep keratometric value; SE = spherical equivalent; opt. ACD = optical anterior chamber depth.

  Fig. 2 A scatterplot of the differences in central macular thicknesses and subretinal fluid height with axial lengths between eyes before and after resolution of serous retinal detachment. The differences in axial lengths were significantly associated with differences of (A) central macular thickness and (B) subretinal fluid height (r = −0.616, p < 0.001 and r = −0.637, p < 0.001, respectively)
