Mutations in the BIGH3 gene on chromosome 5q31 cause four distinct autosomal dominant diseases of the human cornea: granular (Groenouw type I), Reis-Bücklers, lattice type I, and Avellino corneal dystrophies. All four diseases are characterized by both progressive accumulation of corneal deposits and eventual loss of vision. We have identified a specific(More)
PURPOSE To compare the outcome of phacoemulsification surgery in patients with and without prior vitrectomy, adjusted for confounding factors. DESIGN Retrospective cohort study. PARTICIPANTS AND CONTROLS Thirty-one consecutive eyes undergoing phacoemulsification after pars plana vitrectomy (PPV) and 116 consecutive eyes undergoing phacoemulsification(More)
PURPOSE To investigate possible adverse effects of a yellow-tinted intraocular lens (IOL) on scotopic sensitivity and hue discrimination. SETTING Departments of Ophthalmology, Columbia University and New York University School of Medicine, New York, New York, USA. METHODS Nine patients with a yellow-tinted IOL in 1 eye and a colorless ultraviolet IOL in(More)
The purpose of this case study is to describe the studies undertaken in order to improve remote patient monitoring devices (RPM), specifically The BL Healthcare Access Tablet. Current RPM devices are expensive devices that are not well designed to reflect the needs, experiences and limitations of the user. In this paper, we propose mobile application(More)
Flexible endoscopes produce high-quality images, are small in size, and can deliver microsurgical instruments or laser probes. Early attempts at orbital endoscopy were limited by the relatively large size and poor visualization of rigid endoscopes. We performed endoscopic orbital exploration using the Olympus HYF flexible endoscope in four live dog orbits.(More)
Anterior lenticonus is an ocular abnormality that can occur in Alport's syndrome. In this study, Scheimpflug slit imaging analyses were employed for quantitative and objective evaluation of lens changes associated with Alport's syndrome. It was determined that while the apices of the lenticular protrusions are central in the vertical plane, they are nasally(More)
PURPOSE To obtain objective measurements of corneal light scattering after excimer laser keratectomy, and to evaluate the relation of light scattering to clinical haze grading and visual acuity. METHODS The authors measured best-corrected visual acuity, subjective clinical haze grade, and corneal light-scattering index in patients undergoing(More)
PURPOSE To compare the incidence of visually significant pseudophakic macular edema after uneventful phacoemulsification in patients treated postoperatively with topical prednisolone and those treated with topical prednisolone and nepafenac 0.1% suspension (Nevanac). SETTING Edward S. Harkness Eye Institute of Columbia University, New York, New York, USA.(More)
Continuous refinements in vitreoretinal surgical techniques and an increasing number of posterior segment disorders are being successfully managed with pars plana vitrectomy (PPV). This has resulted in an increase in the number of vitrectomized eyes seen by cataract surgeons. Cataract surgery in previously vitrectomized eyes has been reported to be more(More)
