Abstract
Purpose: Comparison of pars plana vitrectomy (PPV) with immunomodulatory therapy (IMT) for patients with intermediate uveitis (IU).
Methods: A prospective, randomized pilot study was performed on patients with recalcitrant IU associated with degradation of visual acuity (VA) despite standard treatment. Outcome measures (VA, intraocular pressure, anterior chamber and vitreous cellular infiltrate) were collected.
Results: Sixteen patients (18 eyes) were randomized to the PPV IMT group. Nine of 11 eyes (82%) treated with PPV showed resolution of inflammation at follow-up, at 5.93 years. Four of 7 eyes (57%) given IMT had persistent inflammation requiring subsequent PPV. PPV patients showed greater improvement in Snellen line, IOP, and vitreous cell reduction. Three PPV patients had cystoid macular edema (CME) initially; all resolved postoperatively. CME improved in 2 of 3 eyes using IMT.
Conclusions: A higher percentage of patients treated with PPV had improvement of uveitis compared to those given IMT. A multicentered clinical trial is needed to confirm and statistically validate these conclusions.
