Abstract
Purpose :
To retrospectively determine the redetachment rate within 1 year of primary retinal detachment repair by pars plana vitrectomy and/or scleral buckle procedures at a U.S.-based academic medical center.
Methods :
All surgeries performed by five attending surgeons at a hospital-based academic retinal practice were reviewed. All cases of retinal detachment repair (by pars plana vitrectomy and/or scleral buckle) between May, 2017 and July, 2018 determined through a combination of automated searches for Current Procedural Terminology (CPT) codes and International Classification of Diseases (ICD) codes and a manual review of all surgical retinal procedure and diagnoses listed in surgical logs for the same time period were selected for manual review. These charts were analyzed to determine the type of retinal detachment and the post-operative outcomes during the 1 year following repair. For this study, primary rhegmatogenous retinal detachments were included, while tractional detachments (e.g. proliferative diabetic retinopathy, retinopathy of prematurity, and proliferative vitreoretinopathy detachments), detachments due to major ocular trauma, complex detachments (e.g. giant retinal tears and keratoprosthesis cases), and serous retinal detachments were excluded. Pre-operative notes, operative reports, and all post-operative visits for 1 year were reviewed. Retinal tear location, preoperative macular attachment status, pre- and postoperative visual acuity, post-operative retinal attachment status, and presence of post-operative PVR was recorded.
Results :
230 cases met inclusion and exclusion criteria. At 1 year of follow up, 91.2% of patients maintained reattachment (single surgery success), while 8.8% (21 patients) re-detached. Of the patients who experienced a redetachment, 94% of redetachments occurred within the first postoperative month and 100% of redetachments occurred within the first 6 months. Logistic regression analysis did not reveal any statistically significant preoperative risk factors for redetachment.
Conclusions :
This study characterizes the rate of redetachment following primary rhegmatogenous retinal detachment repair at a major academic medical center. The findings are consistent with primary surgery success rates reported at other centers. None of the preoperative risk factors analyzed were associated with redetachment, however, there were a small number of redetachments.
