    Abstract:
    PURPOSE: To present the outcomes of pars plana vitrectomy (PPV) in patients with infectious, non-infectious, and unidentified uveitis, focusing on visual and clinical outcomes, diagnostic yield, and surgery-related complications. METHODS: This retrospective, single-center study included patients who underwent 23-gauge PPV for the management of uveitis and had at least 6 months of follow-up. Patients were divided into infectious, non-infectious, and unidentified uveitis groups based on definitive diagnosis after surgery. Etiologies of uveitis, indications for surgery, diagnostic yield, visual outcomes, presence of cystoid macular edema (CME), immunosuppressive drugs, intraoperative and postoperative complications, and repeated vitrectomies were reviewed. RESULTS: This study included 62 eyes of 54 patients. Twenty eyes were diagnosed with infectious uveitis, 24 eyes with non-infectious uveitis, and 18 eyes with unidentified uveitis. The diagnostic yield of vitrectomy was 41.7%. Mean BCVA significantly improved at postoperative 1 month compared to baseline and remained stable at following time-points in all groups. The most common early postoperative complication was increased intraocular pressure (17%), and late complication was cataract (36%). Nine eyes underwent re-vitrectomy and the most common cause was retinal detachment with proliferative vitreoretinopathy (PVR). CONCLUSION: PPV seems to be effective in diagnosing cases of unknown origin, improving visual acuity, and reducing the need for systemic immunosuppressive drugs. PVR is the most serious complication with poor prognosis that requires repeated surgery in patients with uveitis.
