OBJECTIVE To describe an optimized surgical technique for feline vitrectomy which reduces bleeding and aids posterior gel clearance in order to facilitate stem cell delivery to the inner retina using cellular scaffolds. PROCEDURES Three-port pars plana vitrectomies were performed in six-specific pathogen-free domestic cats using an optimized surgical technique to improve access and minimize s...

Aims: To compare the results of pars plana vitrectomy (PPV) and combined scleral buckling—PPV (SB/PPV) in phakic rhegmatogenous retinal detachments with inferior breaks. Methods: Randomized, prospective, clinical controlled trial of forty consecutive phakic eyes with primary rhegmatogenous retinal detachment, associated with inferior breaks and not complicated by proliferative vitreoretinopathy...

PURPOSE To assess the trends in pars plana vitrectomy surgery rates and factors affecting rate change between 2002 and 2013 in South Korea. METHODS Data from National Health Insurance Service-National Sample Cohort 2002-2013, which represents 1,025,340 samples with a sampling rate of 2.2% from the total eligible Korean population, was analyzed. RESULTS A total of 3,816 vitrectomy procedures...

purpose: to assess the clinical course, determine the efficacy and safety of oral methotrexate in the control of intraocular inflammation and evaluate the outcomes of lensectomy-vitrectomy and goniosynechiolysis in pediatric vkh-associated panuveitis. methods: in this retrospective non-comparative interventional case series, 10 patients (20 eyes) with pediatric vkh-associated panuveitis (onset ...

We aimed to compare the results of pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling, an alternative therapeutic strategy, with those of medical treatment for chronic macular edema. We conducted a review of the literature on the microscopic, anatomical, and functional reasons for performing PPV with ILM peeling in patients with diabetic macular edema (DME). We searched t...

PURPOSE To examine retrospectively the visual outcomes in patients undergoing vitrectomy for epiretinal membranes secondary to sarcoid uveitis. METHODS Eleven consecutive patients (11 eyes) with epiretinal membrane and uveitis associated with sarcoidosis underwent pars plana vitrectomy. RESULTS Nine eyes (82%) gained two or more lines of Snellen visual acuity at 1-12 months after surgery. H...

OBJECTIVE To determine the visual outcome of patients who underwent pars plana vitrectomy for dropped nucleus after phacoemulsification. STUDY DESIGN Interventional case series. PLACE AND DURATION OF STUDY LRBT Free Base Eye Hospital, Karachi, from February 2008 to January 2011. METHODOLOGY Forty-eight eyes of forty eight patients having history of dropped nucleus (soft remnant, half nucl...

BACKGROUND/AIMS This is the first nationwide prospective study to investigate the incidence and risk factors of endophthalmitis following pars plana vitrectomy (PPV). METHODS This was a prospective, nationwide case-control study. Cases of presumed infectious endophthalmitis within 6 weeks of PPV were reported via the established British Ophthalmological Surveillance Unit. The surveillance per...

Background. Primary pars plana vitrectomy (PPV) is often performed by vitreoretinal fellows. We aimed to evaluate the incidence of retinal breaks and detachments (RD) after fellow-performed PPV. Methods. We reviewed 119 consecutive cases of standard 3-port primary PPVs on 115 patients at a teaching institution from 2003 to 2006. In all cases, the primary surgeon was a vitreoretinal fellow. Pati...
