Retrospective cohort study evaluates anatomical and visual outcomes of vitrectomy in retinal detachment cases, suggesting potential implications for treatment choices.
Key Points
This study aims to evaluate the anatomical and functional outcomes following primary pars plana vitrectomy for giant retinal tear-related retinal detachment, comparing the effectiveness of gas versus silicone oil tamponade.
Retrospective analysis of 110 eyes undergoing primary PPV for GRT-RRD between 2012 and 2024.
Comparison of outcomes between silicone oil and gas groups using univariable and propensity score matching analyses.
Single surgery anatomical success and best-corrected visual acuity were assessed using logistic and linear regression methods.
Single surgery anatomical success (SSAS) was achieved in 88.2% of eyes, and final anatomic success (FAS) in 96.3%.
After matching, male sex correlated with higher odds of SSAS (OR 4.54, 95% CI 1.75-11.75; p=0.002), while PVR grade C correlated with lower odds (OR 0.10, 95% CI 0.02-0.45; p=0.003).
In macula-on matched eyes, silicone oil was associated with worse final visual acuity (MD +0.179 logMAR, 95% CI 0.018 to 0.341; p=0.030).
