Abstract

Purpose: To identify clinical and surgical risk factors associated with recurrent rhegmatogenous retinal detachment (RRD) in the same eye and RRD in the fellow eye.

 

Study Design: Retrospective chart review.

 

Methods: A retrospective analysis of clinical data over four years was conducted on adult patients undergoing RRD repair at two tertiary care centers. A total of 1,000 consecutive RRDs repaired between January 2018 to January 2022 were identified. Preoperative clinical characteristics, method of repair, and post-operative outcomes were evaluated using bivariate and multivariable analyses to identify variables associated with RRD recurrence in the same eye and RRD in the fellow eye. Primary outcomes measured were RRD recurrence and RRD in fellow eyes.

 

Results: Amongst the 1,000 patients, the mean age was 60.0 years and 40% were female. At baseline, 41% of the eyes were pseudophakic. RRD history was noted in 20% of the eyes with RRD and 10% of the fellow eyes at presentation. RRD recurred in 22% of eyes, primarily up to 80 days post-surgery. In the fellow eye, incident RRD occurred in 5% of the patients, typically beyond one year after the initial detachment in the presenting eye. Postoperative visual acuity significantly improved at one year for all eyes with RRD (p<0.0001). Bivariate analysis identified significant differences in recurrent RRD cases compared to those with no recurrence, including female sex, baseline visual acuity, detachment extent, and tamponade agents. After adjusting for confounders, only the extent of detachment in clock hours at presentation (p=0.0048) and pneumatic retinopexy (p=0.0317) significantly predicted RRD recurrence. For the fellow eyes, age (p=0.0135) and male sex (p=0.0010) were significant predictors of RRD.

 

Conclusion: Our study highlights the association of detachment extent and pneumatic retinopexy as predictors of recurrent RRD, which was most commonly noted up to 80 days post-operatively. Age and male sex are also risk factors for RRD in the fellow eye, which is commonly noted beyond one year after the initial detachment in the presenting eye. These findings emphasize risk stratification of patients and the necessity for follow-up care, particularly during the one-year post-operative follow-up period.
