Introduction: primary open-angle glaucoma (POAG) is a chronic and progressive anterior optic neuropathy characterized by perimetric alterations pathological excavation of the disc in absence other ocular pathologies or congenital anomalies. It usually accompanied an increase intraocular pressure. Gonioscopic examination confirms that iridocorneal angle open. The term "risk factor" defined as co...

Background: Elevated intraocular pressure (IOP) is one of the most important factors for diagnosis and monitoring glaucoma. IOP currently only modifiable risk factor glaucoma, cornea transparent tissue covering front eye. It a powerful refracting surface, providing 2/3 eye's focusing power. The adult about 1/2 millimeter thick comprised 6 layers: epithelium, Bowman's membrane, stroma, Dua's lay...

purpose: to evaluate the relationship between central corneal thickness (cct) and optic disc area in patients with primary open angle glaucoma (poag). methods: the study was performed on patients with poag who were being followed at johns hopkins hospital. all patients underwent thorough eye examination, optic disc imaging with the heidelberg retina tomograph ii (hrt ii), and ultrasound corneal...
