The Effect of Scleral Buckling Surgery on Choroidal Thickness Measured by Enhanced Depth Optical Coherence Tomography: A Cross-Sectional Study.
BACKGROUND
To assess the anatomical changes taking place in the choroid after a scleral buckle (SB) procedure for retinal detachment repair.


METHODS
This cross-sectional study looked at 23 adults with a history of unilateral retinal detachment repaired with a SB or other encircling element. The subjects underwent bilateral Enhanced Depth Spectral Domain Optical Coherence Tomography to image the choroid. The choroidal thickness (CT) was measured, and the non-operative eye was used as an internal control.


RESULTS
CT was measured to be 170.8 ± 60.9 µm (mean ± SD) in eyes with SBs compared to 175.1 ± 61.9 µm in non-operative eyes. There was no statistically significant difference between the two groups (mean 4.3 µm, 95% CI -8.7, 17.3, p value 0.4973, paired t test).


CONCLUSIONS
Placement of an SB as part of a surgery to repair retinal detachment did not significantly alter CT at the macula.
