Primary open-angle glaucoma is not associated with photoreceptor loss.
PURPOSE To determine if photoreceptors die in primary open-angle glaucoma. METHODS Retinas were examined in a masked fashion from nine standard locations of 14 eyes with documented open-angle glaucoma and from nine age-matched control eyes. The number and density of photoreceptors, as well as the area and height of the outer nuclear layer, were calculated with an automated image analysis syst...
متن کاملPrimary open-angle glaucoma
Primary open-angle glaucoma (POAG) is an idiopathic disorder in which the resistance to outflow through the trabecular meshwork gradually increases and the intraocular pressure (IOP) rises, causing irreversible damage to the optic nerve POAG is the second most common cause of vision loss in the U.S. Usually asymptomatic until advanced visual field loss has occurred; less than 50% of those...

متن کاملAssociation between p53 Codon 72 (Arg72Pro) Polymorphism and Primary Open-Angle Glaucoma in Iranian Patients
Background: Glaucomatous neuropathy is a type of cell death due to apoptosis. The p53 gene is one of the regulatory genes of apoptosis. Recently, the association between the p53 gene encoding for proline at codon 72 and primary open-angle glaucoma (POAG) has been studied in some ethnic groups. This study is the first association analysis of POAG and p53 codon 72 polymorphism in Iranian patients...
متن کاملRetinal oximetry in primary open-angle glaucoma.
PURPOSE. To determine whether retinal vessel oxygen saturation is affected in primary open-angle glaucoma (POAG) patients. METHODS. Retinal oxygen saturation in patients with POAG was measured in retinal vessels with a spectrophotometric retinal oximeter in darkness, and visual fields were obtained. Oxygen tension (Po(2)) was calculated from oxygen saturation values. Statistical analysis was pe...
