Abstract
Persistent fetal vasculature (PFV) is a congenital anomaly associated with significant surgical challenges, including a high risk of postoperative retinal detachment (RD). This study aimed to evaluate the impact of surgical approach and axial length (AL) on RD risk and visual outcomes in pediatric PFV management. A retrospective cohort study was conducted involving 76 eyes of 74 patients who underwent cataract surgery for PFV between 2014 and 2022. Patients were categorized by RD status postoperatively (14 with RD, 62 without RD). Key predictors, including surgical approach (corneal vs. pars plicata), AL, and age at surgery, were analyzed. The primary outcomes were RD incidence and final best-corrected visual acuity (BCVA). Compared to the pars plicata approach, the corneal approach was associated with a significantly lower risk of RD, as indicated by a multivariate odds ratio of 0.08 (95% CI 0.01-0.6, P = 0.011). A shorter AL increased the risk of RD (median 17 vs. 20mm, P = 0.002). The RD group showed poorer visual outcomes (P < 0.001), with a 71% loss of light perception. Surgery before 3months improved outcomes, regardless of RD. Visible ciliary processes were strongly correlated with RD (P < 0.001). Corneal surgical approach and longer AL are associated with a lower RD risk in PFV cataract surgery. Early intervention and thorough preoperative assessment of the AL and ciliary processes are crucial for optimal outcomes.
