Predictors of visual outcomes and recurrence after pars plana vitrectomy for uveitis: A 3-Year longitudinal cohort study.

Following pars plana vitrectomy, best-corrected visual acuity (BCVA) improved significantly and remained stable through 36 months (P < 0.001).

Systemic corticosteroid doses and the number of immunomodulatory agents were significantly reduced at 36 months (both P < 0.001), whereas these improvements were not observed in the reference group.

Multivariable analyses identified worse baseline BCVA and higher preoperative intraocular pressure as predictors of poorer visual outcomes.

Higher preoperative corticosteroid dose (> 15 mg/day) was associated with improved visual recovery but increased recurrence risk.
