PURPOSE To describe the systemic and visual characteristics and prognosis in patients with posterior ischemic optic neuropathy (PION). DESIGN Observational case series. METHODS Retrospective chart review in a multicenter setting. Seventy-two patients (98 eyes) with a clinical diagnosis of PION. Co-morbid systemic diseases and visual function were(More)
PURPOSE To evaluate optic nerve vascular density using swept source optical coherence tomography angiography (OCTA) in patients with early primary open angle glaucoma (POAG), pre-perimetric glaucoma and normal eyes. METHODS This is a prospective, observational study including 56 eyes in total and divided into 3 groups; 20 eyes with mild POAG, 20(More)
The presence of increased subarachnoid fluid around the optic nerve as measured by ultrasound has been shown to be associated with elevated intracranial pressure, as well as a number of other conditions. This finding has proved useful for distinguishing optic disc elevation secondary to papilledema from disc elevation attributable to other causes. This(More)
Visual loss in patients with encephalotrigeminal angiomatosis or Sturge-Weber syndrome usually results from secondary glaucoma or from damage to the retrogeniculate pathways by the angiomatous lesions. Optic neuropathy has not been reported as a component of this syndrome. This report describes a patient who developed bilateral optic neuropathy with(More)
PURPOSE The purpose of this study is to quantify the normal retinal thickness (RT) and retinal nerve fiber layer thickness (RNFLT), and to obtain cross-sectional area measurements of the main retinal artery and vein in the rabbit animal model using spectral domain optical coherence tomography (SD-OCT). MATERIALS AND METHODS Fifteen eyes of 15 adult(More)
