Corneal hysteresis but not corneal thickness correlates with optic nerve surface compliance in glaucoma patients.
PURPOSE To investigate relationships between acute intraocular pressure (IOP)-induced optic nerve head surface deformation and corneal hysteresis and thickness in glaucomatous and nonglaucomatous human eyes. METHODS This was a prospective experimental study of 100 subjects (38 with glaucoma, 62 without glaucoma). Data collected included spherical equivalent, optic disc diameter, central corne...
متن کاملCorneal hysteresis in patients with glaucoma-like optic discs, ocular hypertension and glaucoma
BACKGROUND To compare corneal hysteresis (CH) measurements between patients with glaucoma, ocular hypertension (OHT) and glaucoma-like optic discs (GLD)- defined as a cup to disc ratio greater than or equal to 0.6 with normal intraocular pressure (IOP) and visual fields. The secondary aim was to investigate whether corneal resistance factor (CRF) and central corneal thickness (CCT) differ betwe...
متن کاملPeripapillary Intrachoroidal Cavitation and Optic Pit in a Case of High Myopia and Glaucoma
Purpose: To report a case of peripapillary intrachoroidal cavitation (choroidal schisis) and optic pit in a case of high myopia and open-angle glaucoma. Case report: A 30-year-old high myopic man was referred to our clinic for presumed peripapillary choroidal tumors. In funduscopy, there were two yellow-orange and slightly elevated peripapillary lesions in both eyes with indistinct margins. A s...
متن کاملThe Optic Nerve in Glaucoma
To recognize and to assess glaucomatous changes at the optic nerve, it is important to know the characteristics of the normal optic disc. As in the other biological variables, the appearance of the optic disc varies widely among healthy individuals. This fact is complicate the recognition of the pathological changes. ‘Optic Disc’ is frequently used to describe the portion of the optic nerve cli...
متن کاملPit-like changes of the optic nerve head in open-angle glaucoma.
Six patients with open-angle glaucoma and acquired pit-like changes in the optic nerve head are presented. In 1 patient evolution of the pit-like defect is documented. In all 6 patients progression of associated visual field deficits is described. It is suggested that such pit-like changes in selected patients with glaucoma may not represent congenital lesions but rather local, progressive nerv...
