The effect of axial length on pseudophakic retinal detachment

PurposeThe purpose of the study was to analyse the surgical management and outcome regarding axial length in the population affected by pseudophakic retinal detachment (PRD) 2015–2020.MethodThe patients included were from an observational cohort study of patients undergoing cataract surgery in the region of Skåne during 2015–2017. Data were retrieved from the Swedish National Cataract Register and cross‐referenced with cases of PRD in the same region from 2015 to 2020. The surgical method used and findings at follow‐up were recorded. The patients were stratified according to axial length (AL) to <25 mm, 25 ≤ n < 26.5 mm and ≥26.5 mm. The main outcome was primary success with one surgery apart from silicone oil removal. The secondary outcome was postoperative visual acuity.ResultsIn the whole study group of 58 624 cases, complete follow‐up data were available for 288 eyes. The median follow‐up time was 324 days, and primary operation was successful in 82.9% of these cases. The median visual acuity was 0.31 (LogMAR). In the stratification those with AL < 25 mm had a primary success of 75.8%, AL 25 ≤ n < 26.5 mm of 87.9% and ≥26.5 mm of 95.8%.ConclusionsThe primary anatomical success was 82.9% in the whole group of PRD but with stratification they had an increasing number of primary success with longer AL.
