Abstract
Purpose :
The aim of this study was to evaluate the changes in central corneal thickness (CCT), anterior chamber depth (ACD), iridocorneal angle (ICA) and axial length (AL) following circumferential silicone sponge scleral buckling surgery.
Methods :
Twenty eyes with rhegmatogenous retinal detachment that underwent circumferential silicone sponge scleral buckling were included in this prospective, longitudinal study. Changes in CCT, ACD, and ICA were measured with AS-OCT. Axial length was measured with interferometry. Baseline measurements were collected before the surgery. Follow-up data were collected one month and six months after the procedure.
Results :
Twenty patients were included in the study. On average, patients were 42.6 years of age ± 12.86 (range 11-61 years) at the time of the surgery, 55% were male (n=11) and 55% were right eyes (n=11). The mean CCT decreased significantly by the one-month follow-up (mean difference=15.50µm, p<0.001). While the mean CCT increased slightly at the six-month follow-up compared to the one-month follow-up, it was still significantly lower than the mean CCT collected at baseline (mean difference=6.52µm, p=0.001). The mean ACD also significantly decreased at the one month and six month follow-up compared to baseline (mean difference=0.12µm, p=0.004 and mean difference=0.07µm, p=0.012, respectively). There were no significant mean changes of the ICA at 180 degrees and 0 degrees between preoperative and postoperative measurements. The mean axial length increased significantly after one month and six months compared to baseline (mean difference=0.78µm, p<0.001 and mean difference=0.60µm, p<0.001, respectively).
Conclusions :
Circumferential silicone sponge scleral buckling causes important changes in the anterior segment and in the axial length that persists even after 6 months
