BACKGROUND AND OBJECTIVE Ultra wide field technology was originally designed for use in children. The purpose of this study was to evaluate ultra wide field fluorescein angiography (UWFFA) in children. PATIENTS AND METHODS Retrospective case series of patients younger than 13 years who underwent UWFFA. Angiographic findings and their impact on diagnosis(More)
Fibronectin and laminin are clinically relevant plasmin receptors in the eye. Located at the vitreoretinal interface, they are cleaved by ocriplasmin (Microplasmin, ThromboGenics, Iselin, NJ), a novel ophthalmic medication. A series of clinical trials to study ocriplasmin for the treatment of vitreoretinal diseases such as vitreomacular traction, macular(More)
Implanting glaucoma tubes through the pars plana in the setting of a corneal transplant is becoming more common, and there are unique problems associated with such a procedure. A 42-year-old man with multiple previous eye surgeries presented with a nonfunctioning pars plana glaucoma tube. There was no view to the tube tip, but it was presumed to be clogged(More)
Topiramate is known to cause ocular side effects such as refractive changes and angle closure. We describe a patient with an electronegative electroretinogram (ERG) which may have been related to topiramate use. Electronegative ERG's have been associated with other drugs in humans as well as topiramate use in rabbits. However, this would be the first(More)
BACKGROUND Retinal cavernous hemangiomas are rare vascular anomalies, and can be associated with cerebral cavernous malformations (CCM). Distinct mutations have been reported in patients who have both CCMs and retinal cavernous hemangiomas. METHODS Fluorescein angiography, spectral domain optical coherence tomography, and genetic testing were performed on(More)
PURPOSE To report visual acuity, contrast sensitivity and color vision prior to, 1 year after, 2 years after and 3 years after iodine-125 brachytherapy for choroidal and ciliary body melanoma (CCM). DESIGN Prospective interventional case series. PARTICIPANTS Thirty-seven patients (37 eyes) with CCM. METHODS Patients had best-corrected Early Treatment(More)
BACKGROUND Conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma has been well-described, but rarely do these lesions demonstrate intraocular involvement. We report a case of conjunctival MALT lymphoma with intraocular involvement and novel spectral-domain ocular coherence tomography (SD-OCT) findings. PATIENT AND METHODS A 75-year-old woman with(More)
Introduction. Branch retinal vein occlusion (BRVO) is a common retinal vascular condition that results in intraocular inflammatory changes. Ultra wide field fluorescein angiography (UWFFA) is a retinal imaging device that can capture peripheral retinal findings. The purpose of this study was to look for peripheral findings in the fellow eye of patients with(More)
AIM The purpose of this study is to report a case of endogenous endopthalmitis caused by Scedosporium apiospermum with a favorable outcome and review previously reported cases, their treatment regimens and outcomes. METHODS An 83-year-old man with diabetes mellitus, no other immunocompromising risk factors, and a history of S. apiospermum endopthalmitis(More)
