PURPOSE: To report the morphologic changes of the subfoveal choroidal thickness using spectral-domain optical coherence tomography following segmental scleral buckling. DESIGN: Retrospective, observational case series. METHODS: The study included 21 eyes of 20 patients who underwent segmental scleral buckling for the treatment of rhegmatogenous retinal detachment. All patients underwent the measurements of the subfoveal choroidal thickness preoperatively and 1 week, 1 month, and 3 months after the surgery. The changes in choroidal thickness, 4 mm from the fovea, before and 1 week after surgery were analyzed in the buckled and unbuckled side. RESULTS: The preoperative mean subfoveal choroidal thickness of operated eyes was 239.2 ± 91.0 μm. The postoperative mean subfoveal choroidal thicknesses of operated eyes at 1 week, 1 month, and 3 months were 267.6 ± 96.8 μm, 250.6 ± 95.8 μm, and 239.4 ± 95.6 μm, respectively. There were significant differences between preoperative subfoveal choroidal thickness and 1-week-postoperative and 1-month-postoperative subfoveal choroidal thicknesses (P < .01, P = .03, ANOVA), and there was no significant difference between subfoveal choroidal thicknesses preoperatively and 3 months postoperatively (P > .99, ANOVA). The changes in choroidal thickness of the buckled and unbuckled side preoperatively and 1 week postoperatively were not significantly different (n = 8, P = .589, 2-way ANOVA). CONCLUSION: The subfoveal choroidal thickness may change temporarily following segmental scleral buckling surgery. This may be the result of reversible subclinical microcirculatory dysfunction of the choroid.
