Abstract
Purpose:
To evaluate the causes and success rates of pars plana vitrectomy (PPV) in patients with uveitis.
Methods:
Retrospective study of the charts of 15 patients with uveitis (17 eyes) who underwent PPV between the years 2013 and 2014. PPV was performed in the Clinical Hospital of Buenos Aires, José de San Martín. Surgical procedure was throught a conventional 3 port 23 G vitrectomy. 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 70%, (2) diagnostic PPV (DiV) was performed in 30% of the eyes. Eight eyes (28,6%) underwent a combined cataract and vitreous surgery. Visual acuity (VA) improved in 7 eyes (41%), although the effect was transient in 7% of the cases. VA remained stable in 8 eyes (47%) and decreased in 2 (12%). Post-operative complications were (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 and stable improvement of VA was found when PPV was performed with ERM peeling and macular hole, 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.
