Abstract
Scleral buckling has been a reliable treatment option in the repair of primary rhegmatogenous retinal detachments. Occasionally, patients require scleral buckles (SBs) to be removed for various reasons. While outcomes of SB removal have been investigated in this subset of patients, there has not been any large patient series to reach any conclusions. Long-term sequelae of SB removal are debated in the literature, specifically around the risk of redetachment. We performed a retrospective, observational study to evaluate the clinical indications for, and outcomes of, SB removal. No control patients in this retrospective, observational study. Eighty-six individuals with a history of SB removal from June 1, 2000, to January 1, 2021, were followed from a large academic center and a private, retina-only practice in Chicago. Exclusion criteria were age of < 18 years and unplanned or self-explanted SB removal. Data extracted included patient symptoms before SB removal, indications for removal, resolution of symptoms following removal, rate of redetachment, and rate of additional ocular surgery. Secondary outcomes included identifying factors associated with poorer outcomes. Eighty-six eyes with history of SB removal were included with an average follow-up of 4 years. Approximately 60% were males and the mean age at the time of SB removal was 59 years. Leading indications for removal were exposure (61.63%), infection (20.93%), and diplopia/strabismus (19.77%). The average time from SB placement to removal was 12.28 ± 11.16 years. Most patients requiring SB removal presented with symptoms, specifically of pain and discomfort (65.12%), diplopia (22.09%), and drainage/discharge (18.60%). Of these patients, 86.59% experienced symptom resolution following SB removal. Notably, 6.56% (4 eyes) of all eyes with at least 1 year of follow-up experienced a redetachment requiring surgery. Within this subset, the average time from SB placement to removal was 2.05 ± 2.01 years and time to redetachment following removal was 15.95 ± 25.71 months. Nine percent of all eyes required additional strabismus or oculoplastic surgery. Scleral buckle removal provides a high rate of symptomatic relief and low risk of subsequent detachment. Nevertheless, close monitoring is warranted to monitor for recurrent retinal detachments.
