Purpose:
To analyze changes in choroidal thickness in patients with recurrent rhegmatogenous retinal detachment (RRD) before and after surgical intervention and to identify factors that influence changes in choroidal thickness.
Methods:
A retrospective observational study was conducted on patients who underwent surgery for recurrent RRD from November 2019 to March 2023. Choroidal thickness was measured using optical coherence tomography at baseline and at 2 and 6 months postoperatively. The study analyzed the impact of various factors on choroidal thickness changes.
Results:
The study included 33 patients, demonstrating a significant decrease in choroidal thickness in the surgical eye compared to the fellow eye over a 6-month period. In the univariate analysis, changes in choroidal thickness were significantly correlated with changes in central retinal thickness (p = 0.048) from baseline to 2 months and with proliferative vitreoretinopathy (PVR) grade from 2 to 6 months (p = 0.009) and from baseline to 6 months (p = 0.020). In the multivariate analysis, an association was found between changes in choroidal thickness from 2 to 6 months and PVR grade (p = 0.030).
Conclusions:
The findings indicate that surgical reattachment in eyes with recurrent RRD leads to a significant reduction in choroidal thickness. The extent of this reduction is influenced by the severity of PVR, highlighting the importance of considering PVR severity when evaluating surgical outcomes in patients with recurrent RRD.
