BACKGROUND Perfluorocarbon liquids are frequently used as intraoperative tools in vitreoretinal surgery and may occasionally be retained in the vitreous cavity. We report a patient who underwent pars plana vitrectomy for a giant tear after receiving blunt trauma to his right eye and sustained postoperative perfluorocarbon liquid residue in the anterior chamber in spite of an intact crystalline ...

INTRODUCTION The causative organism and treatment outcomes of post operative endophthalmitis may vary depending on several factors. OBJECTIVE To find out the causative organisms and visual outcome after an outbreak of post-operative endophthalmitis. MATERIALS AND METHODS An interventional prospective series of cases of clinically suspected endophthalmitis was studied. Eleven patients who pr...

PURPOSE The objectives were to determine by nuclear magnetic resonance imaging (MRI) the target sites of ion delivery in the eye during iontophoresis, compare transscleral and transcorneal ocular iontophoresis, and monitor the distribution of a probe ion in the anterior chamber and vitreous after iontophoretic delivery. METHODS Thirty-minute 2-mA anodal constant current transscleral and trans...

Vitreoretinal lymphoma (VRL) is a rare variant of primary central nervous system (PCNSL), mostly diffuse large B cell lymphoma, which affects the retina and/or vitreous with or without optic nerve involvement. The disease course aggressive. Up to 90% patients develop within one year. diagnosis VRL challenging due nonspecific chronic and relapsing uveitis made by anterior chamber tab aspirate bi...

PURPOSE While rearing chicks in constant light (CL) inhibits anterior segment growth, these conditions also induce excessive enlargement of the vitreous chamber. The mechanisms underlying these effects are poorly understood although it has been speculated that the enlarged vitreous chambers are a product of emmetropization, a compensatory response to the altered anterior segments. We examined t...

PURPOSE To evaluate the efficacy of a biodegradable polymeric scleral plug containing the immunosuppressive agent, FK506, in a rabbit model for experimental uveitis. METHODS The scleral plugs were prepared by dissolving poly(DL-lactide-co-glycolide; PLGA) and FK506 (weight, 8.5 mg; length, 5 mm; 1% FK506). The release of FK506 was evaluated in vitro by spectrophotometry on days 1, 3, 7, 14, 2...

OBJECTIVE To resolve the controversy surrounding the shape and relationship of posterior vitreous spaces by characterizing the connections between the premacular bursa, the area of Martegiani, and Cloquet's canal. DESIGN Comprehensive posterior vitreous maps were created using swept-source optical coherence tomography (SS OCT) in a cross-sectional study. PARTICIPANTS The posterior vitreous ...

Three cases are described of acute glaucoma following vitrectomy and silicone oil injection in proliferative vitreous retinopathy. The first case developed silicone-induced pupillary block in a phakic eye. Cases 2 and 3 developed elevated pressure in aphakic eyes with deep anterior chambers. Cases 1 and 3 were treated by laser iridectomy. Case 2 was treated by removal of silicone. The pathogene...
