Sixty-four consecutive pars plana vitrectomies were performed with the Douvas roto-extractor for anterior and posterior vitreous opacities. Eighty-four per cent of the anterior segment vitrectomy patients obtained improvement in visual acuity after surgery. Only 60% of the posterior segment patients obtained improvement in visual acuity, while only 45%

20-Gauge Transconjunctival Pars Plana Vitrectomy
Ophthalmic Surgery, Lasers and Imaging Retina, 2007<P>This article describes a transconjunctival technique for pars plana vitrectomy using 20-gauge instruments. Sclerotomies are performed directly through the conjunctiva, Tenon’s capsule, and sclera with a 19-gauge microvitreoretinal blade.

PROGNOSTIC PARAMETERS IN PARS PLANA VITRECTOMY
Acta Ophthalmologica, 1983Based on a period of introduction with the vitrectomy technic the visual acuity results in 143 consecutive cases performed between 1976 and 1980 are related to the anamnestic information, the pre‐, per‐ and post‐operative findings. In this introductional period the patients referred had longstanding retinovitreal changes, and, because of lack of ...

Endophthalmitis after Pars Plana Vitrectomy
American Journal of Ophthalmology, 1977In three cases of bacterial endophthalmitis following pars plana vitrectomy the important diagnostic findings included increased orbital pain, decreased visual acuity, and the presence of a hypopyon. Despite agressive antibiotic therapy, all three eyes became blind, and two progressed rapidly to phthisis.

Pars Plana Vitrectomy in Ocular Trauma
American Journal of Ophthalmology, 1979Visual improvement was achieved in 62% of 100 consecutive patients with ocular trauma treated by pars plana vitrectomy. Anterior segment injuries had a better prognosis than posterior segment injuries, and retinal detachment was a poor prognostic sign.

Phacoemulsification Combined With Pars Plana Vitrectomy
Ophthalmic Surgery, Lasers and Imaging Retina, 1991ABSTRACT Phacoemulsification combined with pars plana vitrectomy was performed on seven patients with both cataracts and vitreoretinal disease. Six of the seven had a posterior chamber intraocular lens (PC-IOL) placed in the capsular bag following cataract extraction.

Pars plana vitrectomy (PPV) allows the treatment of a multitude of vitreoretinal disorders involving the vitreous, the retina or the choroid. There is a multitude of possible surgical sequences: peeling maneuvers, liquid perfluorocarbone, removal of traction and media opacities, retinopexy or destructive photocoagulation, and as ultima ratio ...

Combined Phacoemulsification and Pars Plana Vitrectomy
Archives of Ophthalmology, 1990Combined phacoemulsification and pars plana vitrectomy were performed in eight eyes with cataract and vitreoretinal disease. Six eyes had tractional retinal detachment and/or nonclearing vitreous hemorrhage, one eye had a retained metallic intraocular foreign body, and one eye had a traumatic retinal detachment.

Specular Microscopy in Pars Plana Vitrectomy
Archives of Ophthalmology, 1983A prospective study of endothelial cell loss following pars plana vitrectomy and pars plana vitrectomy with lensectomy was performed in 21 eyes. Fifteen diabetic patients had either vitrectomy alone or vitrectomy with lensectomy. Six nondiabetic eyes were also included in this study. The average cell loss was between 2.3% and 3.9% in all cases.

Suprachoroidal hemorrhage during pars plana vitrectomy
Current Opinion in Ophthalmology, 2001Suprachoroidal hemorrhage is an uncommon but serious complication of pars plana vitrectomy that can be associated with a guarded visual prognosis. Risk factors for development of suprachoroidal hemorrhage during pars plana vitrectomy include high myopia, history of previous retinal detachment surgery, rhegmatogenous retinal detachment, use of ...
