Pars plana vitrectomy in uveitis of diverse etiologies: indications and surgical outcomes.
This retrospective cohort of 32 eyes from 30 patients with uveitis reported improved visual acuity after pars plana vitrectomy, 93.8% final anatomical success among retinal-detachment cases, and no severe postoperative inflammation.

This retrospective cohort of 32 eyes from 30 patients with uveitis reported improved visual acuity after pars plana vitrectomy, 93.8% final anatomical success among retinal-detachment cases, and no severe postoperative inflammation.
Research significance
The record supports PPV as a surgical and diagnostic approach for selected uveitis complications; any pediatric-oncology value—such as facilitating diagnosis of suspected vitreoretinal lymphoma—is inferential because no pediatric subgroup, cancer-specific diagnostic yield, or oncologic outcome is reported.
Source abstract
BACKGROUND: To evaluate the indications, surgical outcomes, and diagnostic role of pars plana vitrectomy (PPV) in uveitis of diverse etiologies. METHODS: This retrospective study included 32 eyes (30 patients) undergoing 23-gauge PPV during 2019-2025. Uveitis etiology, surgical indications, and pre- and postoperative best-corrected visual acuity (BCVA) were analyzed. The primary outcome was change in BCVA, while secondary outcomes included anatomical success in retinal detachment (RD) cases, clinically meaningful visual improvement, diagnostic yield, and postoperative complications. RESULTS: The most common etiologies were idiopathic uveitis (16.7%) and suspected primary vitreoretinal lymphoma (16.7%). Main surgical indications included tractional RD (28.1%), rhegmatogenous RD (21.9%), and diagnostic vitrectomy (18.8%). Final anatomical success was achieved in 93.8% of RD cases. BCVA improvement remained statistically significant at 1, 6, and 12 months after correction for multiple comparisons, while a gain of ≥ 2 Snellen lines was achieved in 46.2% of eyes at the final follow-up visit. No severe postoperative inflammation occurred. CONCLUSIONS: PPV is a safe and effective approach for managing vitreoretinal complications and diagnostic evaluation in uveitis, with favorable anatomical and functional outcomes.
