    Abstract:
    PURPOSE: To evaluate the causes and success rates of pars plana vitrectomy (PPV) in uveitis patients. METHODS: Retrospective study of the charts of 26 uveitis patients (28 eyes) who underwent PPV between the years 2008 and 2011. We examined surgical indications and success rates, based on visual outcomes, complications and diagnosis in case of vitreous biopsy. RESULTS: (1) Therapeutic PPV (TV) was performed in 36% of the eyes, (2) TV combined with epiretinal membrane (ERM) peeling in 21% and (3) diagnostic PPV (DiV) was performed in 64% of the eyes. Eight eyes (28,6%) underwent a combined cataract and vitreous surgery. Visual acuity (VA) improved in 16 eyes (57%), with a mean improvement of -0,9 log of the minimum angle of resolution (logMAR), although the effect was transient in 7% of the cases. VA remained stable in 11 eyes (39%) and decreased in 1 (4%). Post-operative complications were cystic macular oedema (CMO) in 3 eyes (11%), cataract in 5 eyes (18%) and retinal detachment in 2 eyes (7%). Diagnostic tests were performed in 18 eyes with a success rate of 55%. CONCLUSIONS: In our series of patients with uveitis, a good andstable improvement of VA was found when PPV was performed with ERM peeling while the effect on VA was more transient in the other cases. A good success rate of diagnosis was also found in DiV. However, considering the possible severe complications, diagnostic vitrectomy should be limited to selected cases.
