Abstract: :
Purpose: to investigate the indications for pars plana vitrectomy (PPV) in a reference eye hospital in Joinville, State of Santa Catarina, southern Brazil. Methods: retrospective, noncomparative, consecutive case series. Cases included all patients who performed PPV at Sadalla Amin Ghanem Eye Hospital between January 1, 2001 and June 30, 2003. Demographic data and indications for PPV were obtained from patients medical records. Results: Two hundred and forty–four patients underwent 265 PPV. One hundred and sixty were male (65,6%) and mean age was 50,4 years old (7–86 yo). One hundred and seventy–four patients (71,3 %) came from outside Joinville. Pars plana vitrectomy was indicated for treatment of rhegmatogenous retinal detachment in 113 cases (46,3%), proliferative diabetic retinopathy in 55 cases (22,5%), epiretinal membrane in 18 cases (7,4%), other causes of vitreous hemorrhage (trauma, retinal branch vein occlusion, retinal arterial macroaneurysm and Terson's syndrome) in 15 cases (6,1%), intraocular foreign body in 12 cases (4,9%) and macular hole in 12 cases (4,9%). Other diagnosis included lens displacement (7 cases, 2,9%), uveitis (6 cases, 2,5%), endophthalmitis (3 cases, 1,2%), asteroid hyalosis (2 cases; 0,8%) and malignant glaucoma (1 case, 0,4%). There were 21 reoperations and its indications included proliferative vitreoretinopathy (16 cases, 76,2%), recurrent vitreous hemorrhage (4 cases, 19 %) and endophthalmitis (1 case, 4,8%). Conclusions: Although PPV was indicated for treatment of several posterior segment eye diseases, rhegmatogenous retinal detachment and proliferative diabetic retinopathy were, by far, the most common indications for the first procedure and proliferative vitreoretinopathy was the main cause of reoperation at this tertiary eye healthcare service in Joinville, Brazil.
