To evaluate the clinical course and visual results after pars plana vitrectomy (PPV) for the treatment of posterior segment complications in patients with chronic uveitis
Ophthalmology Department of the Istanbul Education and Research Hospital
Ten eyes of 8 patients with chronic uveitis who underwent PPV for posterior segment complications in the Ophthalmology Department of the Istanbul Education and Research Hospital were enrolled in this retrospective study. There were 4 females and 4 males in the study; the mean age was 46.5 years ±10.8. Four patients had Behçet"s disease, 1 patient had serpiginous chorioretinopathy, 1 patient had tuberculosis, 1 patient had toxoplasmosis chorioretinitis and 1 patient had idiopathic granulomatous uveitis. Indications for PPV were dense vitreous opacities in 3 eyes, macular pucker in 3 eyes, vitreous hemorrhage in 4 eyes. Mean follow-up time was 37 months.
Inflammation levels decreased and visual acuity improved after the surgery. After the surgery best corrected visual acuity improved in 7 eyes (70%). No significant visual improvement occurred in 1 eye (10 %). Visual acuity decreased in 2 eyes (20%). In one eye, PPV was performed with cataract surgery. Recurrence of inflammation was seen in 2 of 3 eyes who underwent PPV for macular pucker. Other postoperative complications were IOP elevation in 3 eyes, cataract occurence in 3 eyes, accumulation of deposits in front of intra ocular lens (IOL) in 3 eyes, macular edema development in 1 eye. Three eyes with preoperative clear lenses developed cataract within six months of PPV. Phacoemulsification and IOL implantation was performed these eyes. IOL exchange was performed in 1 eye who had intensive accumulation of deposits in front of IOL. Nd: YAG laser capsulotomy was performed in pseudophakic 3 eyes for the development of posterior capsule opacification.
Pars plana vitrectomy in the treatment of the posterior segment complications developed during the course of chronic uveitis is an important approach for stabilizing or improving the visual acuity.
