AIM To determine the long term intraocular pressure (IOP) response to phacoemulsification in patients with and without exfoliation syndrome (XFS). METHODS Prospective, multicentre, cohort study with the following inclusion criteria: age over 50 years, open iridocorneal angle, and cataract. Two groups were enrolled: those with XFS and those without. The(More)
PURPOSE To determine the intraocular pressure (IOP) response to phacoemulsification cataract extraction with posterior chamber intraocular lens (PC IOL) implantation in patients with pseudoexfoliation syndrome. SETTING Eye clinics at the University of Ottawa Eye Institute, Ottawa, Ontario, Canada. METHODS A retrospective cohort study design assigned(More)
Primary vitreoretinal lymphoma is a high-grade intraocular malignancy that presents as a vitritis with creamy subretinal lesions. In cases where the vitritis is dense, the characteristic subretinal lesions can be difficult to see on clinical examination. Novel high-definition imaging techniques that allow for deeper penetration through opaque media could(More)
OBJECTIVE This study examined eating behavior in collegiate women lightweight rowers, runners, and controls. It was hypothesized that rowers would show an increased prevalence of restraint in their eating behaviors, but not probable eating disorder cases as compared with runners or controls, because they are required to make their target weight but are(More)
PURPOSE We compared the reproducibility and mutual agreement of the subfoveal choroidal thickness measurements by expert raters and an automated algorithm in enhanced depth imaging optical coherence tomography (EDI-OCT) images of eyes with nonneovascular age-related macular degeneration (AMD). METHODS We recruited 44 patients with nonneovascular AMD and(More)
Radial peripapillary capillaries (RPCs) comprise a unique network of capillary beds within the retinal nerve fibre layer (RNFL) and play a critical role in satisfying the nutritional requirements of retinal ganglion cell (RGC) axons. Understanding the topographical and morphological characteristics of these networks through in vivo techniques may improve(More)
Retinal capillary networks are critically linked to neuronal health and disease. The ability to perform accurate in vivo examination of human retinal capillary networks is therefore valuable for studying mechanisms that govern retinal homeostasis and retinal vascular diseases. Speckle variance optical coherence tomography (svOCT) is a non-invasive imaging(More)
