To investigate the anatomic and functional results and risk factors for poor visual outcome (PVO) following scleral buckling (SB) for treating primary rhegmatogenous retinal detachment (RRD) in patients with and without high myopia (HM).
It is a retrospective chart review and case-series study. Single-center medical records were reviewed, including demographic features, intraoperative factors and postoperative outcomes. All patients received a 6-month follow-up after surgical intervention. The anatomic and functional outcomes were primary retinal reattachment and postoperative best-corrected visual acuity (BCVA) improvement 6 months after primary surgical treatment, respectively. Postoperative BCVA < 0.1 (logMAR > 1.0) was defined as a PVO.
The overall primary reattachment frequency was 84.1%: 85.3% in non-HM and 80.5% in HM patients (p = 0.300). The average improvement of BCVA was 0.4 logMAR: 0.42 in non-HM and 0.33 in HM patients (p=0.389). A total of 127 patients (39.7%) showed PVO: 42% in non-HM and 32% in HM patients (p = 0.153). Logistic regression showed that primary attachment failure and baseline BCVA were risks factors of PVO in both groups. RRD range was also an independent risk factor in non-HM patients; however, combined SB and PPV was associated with PVO in HM patients.
The risk factors of PVO after surgical treatment of RRD differed between patients with and without HM. In HM RRD patients with unfavorable preoperative conditions, combined SB and PPV is an independent risk factor for poor post-operative vision.
