Parapapillary Deep-Layer Microvasculature Dropout in Primary Open-Angle Glaucoma Eyes With a Parapapillary γ-Zone.
Purpose To explore the clinical characteristics of parapapillary deep-layer microvasculature dropout (MvD) associated with parapapillary γ-zone in primary open-angle glaucoma (POAG). Methods A total of 150 eyes with POAG and 75 age- and axial length-matched control eyes, both having parapapillary γ-zone as determined by spectral-domain (SD) optical coherence tomography (OCT), were included. P...
متن کاملRelationship Between Juxtapapillary Choroidal Volume and Beta-Zone Parapapillary Atrophy in Eyes With and Without Primary Open-Angle Glaucoma.
PURPOSE To evaluate whether quantity of choroidal tissue directly adjacent to the optic nerve differs between eyes with and without glaucoma and whether beta-zone parapapillary atrophy influences this relationship. DESIGN Prospective cohort study. METHODS Subjects were enrolled in a longitudinal, observational study at our institution. We studied 1 eye of 63 primary open-angle glaucoma (POA...
متن کاملGonioscopic Features in Patients with Acute and Chronic Angle-Closure Glaucoma
Background: A number of ocular biometric parameters, iris hiotologic and anatomic characters have been suggested as inciting factors for converting patients with narrow angle to angle-closure glaucoma. This study was conducted to determine if there was any goniscopic difference between patients with acute angle-closure glaucoma (AACG) and chronic angle-closure glaucoma (CACG). Methods: ...
متن کاملParapapillary Atrophy: Histological Gamma Zone and Delta Zone
BACKGROUND To examine histomorphometrically the parapapillary region in human eyes. METHODOLOGY/PRINCIPAL FINDINGS The histomorphometric study included 65 human globes (axial length:21-37 mm). On anterior-posterior histological sections, we measured the distance Bruch's membrane end (BME)-optic nerve margin ("Gamma zone"), BME-retinal pigment epithelium (RPE) ("Beta zone"), BME-beginning of n...
متن کاملGlaucoma in high myopia and parapapillary delta zone
PURPOSE To examine the prevalence of glaucomatous optic neuropathy (GON) in a medium myopic to highly myopic group of patients and its association with parapapillary gamma zone and parapapillary delta zone. METHODS The retrospective observational hospital-based study included patients who had attended the Tokyo High Myopia Clinics within January 2012 and December 2012 and for whom fundus phot...
