PURPOSE To evaluate prospectively the ability to peel epiretinal membranes and to correlate the degree of membrane peeling to anatomic success rates. DESIGN Consecutive, noncomparative, interventional case series. PARTICIPANTS One hundred ninety-three patients. METHODS The extent of membrane peeling and other intraoperative features were correlated to(More)
PURPOSE A new noninvasive laser Doppler flowmetry (LDF) probe (one emitting fiber surrounded by a ring of eight collecting fibers, 1-mm interaxis distance) was tested for its sensitivity to assess the retinal/choroidal blood flow variations in response to hypercapnia, hyperoxia, diverse vasoactive agents and following retinal arteries photocoagulation in(More)
A 68-year-old woman presented to the ophthalmology emergency clinic with a painful left eye of a few hours' duration. One month prior, the patient had presented with a central retinal vein occlusion in the same eye. Examination revealed an intraocular pressure of 32 mm Hg in the left eye with 360 degree angle closure unaltered by indentation, a patent(More)
BACKGROUND To determine the factors associated with anatomical and visual outcomes, and complications when using pneumatic retinopexy in the management of rhegmatogenous retinal detachments. METHODS On a whole, 406 patients having undergone 422 primary pneumatic retinopexies for the management of rhegmatogenous retinal detachment at a tertiary care(More)
PURPOSE Intravitreal (ITV) injection of anti-VEGFs like bevacizumab are widely used to treat neovascular AMD. However, VEGF is essential for biologic functions such as blood pressure regulation. Indeed, anti-VEGF intravenous administration is associated with hypertension. Therefore, the effect of ITV bevacizumab on retinal circulation was examined. (More)
PURPOSE We performed a qualitative and quantitative assessment of contact lens performance at 1 and 6 months among 24 patients enrolled in the Piggyback Bifocal Contact Lens Study. METHODS We fit 24 presbyopic patients with the Piggyback Bifocal Contact Lens System (i.e., a plano soft lens with a 9.4 mm cutout portion on which a bifocal RGP lens rides or(More)
Background To compare the primary anatomical outcome of pars plana vitrectomy, 360° peripheral endolaser, and 15% octafluoropropane C3F8 gas tamponade in patients with uncomplicated rhegmatogenous detachment and inferior retinal breaks, after 24-h postoperative prone positioning to similar patients with 1 week postoperative prone positioning. Methods(More)
PURPOSE Although venous air embolism is a well recognized complication within most surgical subspecialties, it has only been reported recently during eye surgery in one adult, and never before in a child. We describe the case of a 17-month-old boy who sustained a possible air embolism during repair of an open trauma of his right eye. CLINICAL FEATURES A(More)
PURPOSE To report the usage of fibrin sealant in the treatment of retinal detachment in morning glory syndrome. METHODS A case report of an 8-year-old boy with a recent, macula-off, inferior, bullous retinal detachment associated to his morning glory syndrome that was first treated by a pneumatic retinopexy. The following day, his examination revealed a(More)
Ali Dirani1* and Ghassan Cordahi1 1Department of Ophthalmology, University of Montreal, Montreal, Quebec, Canada Retinal pigment epithelial detachment (PED) is defined as an anatomical separation of the retinal pigment epithelium (RPE) from the underlying Bruch layer [1]. Serous and vascularized (fibrovascular) PED are commonly present in eyes with(More)
