PURPOSE To determine the feasibility of using semiautomated analysis of digital fundus images to quantify the differences in retinal vascular diameter between retinopathy of prematurity (ROP) patients with and without plus disease. DESIGN Case-control study. METHODS Thirty eyes of 15 patients with ROP were included in this study. Fourteen eyes of seven(More)
Pseudophakic cystoid macular edema (PCME) is a common complication following cataract surgery. Acute PCME may resolve spontaneously, but some patients will develop chronic macular edema that affects vision and is difficult to treat. This disease was described more than 50 years ago, and there are multiple options for clinical management. We discuss(More)
CONTEXT Recombinant human GH (rhGH) therapy in Prader-Willi syndrome (PWS) has been used by the medical community and advocated by parental support groups since its approval in the United States in 2000 and in Europe in 2001. Its use in PWS represents a unique therapeutic challenge that includes treating individuals with cognitive disability, varied(More)
Defecation rate was monitored during daily 30-min periods as 16 rats were exposed to different sequences of the following three experimental conditions: (a) a fixed-time 60-s food delivery schedule, (b) a massed-food presentation baseline, and/or (c) a no-food baseline. All food delivery was response independent. Rate of defecation increased during(More)
PURPOSE To evaluate the feasibility of using semiautomated analysis of digital fundus images to quantify effects of photocoagulation on retinal vessel diameter in retinopathy of prematurity (ROP). DESIGN Case series. METHODS Fourteen eyes of seven patients with threshold ROP and 12 eyes of six controls were included. Fundus images were captured before(More)
Four pigeons pecked keys for food reinforcers delivered by variable interval 1-min schedules during two successive 50-min sessions or one 100-min session. When 50-min sessions were conducted, they were separated by a 0-, 10- or 30-min delay, spent either inside or outside of the experimental enclosure. Responding usually increased to a peak and then(More)
PURPOSE To assess whether the rate of change of retinal vessel diameter can help identify infants at the highest risk for severe retinopathy of prematurity (ROP). DESIGN Thirty-five infants at risk for ROP were included in this prospective, longitudinal study. METHODS Images were obtained using the NIDEK NM200D noncontact camera (NIDEK Inc, Aichi,(More)
PURPOSE To suggest that sub-Tenon triamcinolone acetonide (TA) injections may be a helpful supplement in patients with scleritis. DESIGN Retrospective, interventional case series. METHODS A retrospective chart review was conducted of all patients at our institution receiving sub-Tenon TA injections for scleritis between August 2001 and August 2007.(More)
PURPOSE To report a case of persistent corneal epithelial erosion in a patient undergoing treatment with erlotinib for her lung cancer. METHODS Report of a 79-year-old woman who presented with a persistent corneal epithelial defect associated with infectious keratitis that waxed and waned for 5 months despite treatment. She had been diagnosed with lung(More)
Two experiments were conducted during which undergraduates responded during a variable-interval (VI) 60-second operant task. The first experiment consisted of either three 60-minute sessions or three 30-minute sessions. During Experiment 1 subjects were informed as to the length of the session and the number of sessions that would be conducted. During the(More)
