Vertical ovalness of glaucomatous cupping.
نویسنده
چکیده
Slit-lamp examination and stereoscopic fundus photography were found to be helpful in differentiating between physiological and glaucomatous cupping of the disc. Vertical ovalness of any cup in the disc should raise the suspicion of glaucoma, and the magnitude of the vertical cup: disc ratio is of particular significance.

Ovalness of the optic cup and disc in the normal eye.
Observations have been made of the horizontal extent of cupping of the optic nerve head in both normal and glaucomatous eyes in an attempt to determine the factors which influence cup size in the normal eye (Armaly, I967; Armaly and Sayegh, I969; Armaly, 1969a, b; Tomlinson and Phillips, I969; Jonsas, I972) and to establish differential diagnostic criteria for glaucomatous excavation (Armaly, I...
متن کاملDifferentiating Glaucomatous from Non-Glaucomatous Optic Nerve Cupping by Optical Coherence Tomography
BACKGROUND In clinical practice, the differentiation of glaucomatous from non-glaucomatous cupping can be difficult, even for experienced observers. The purpose of this study was to evaluate the role of optical coherence tomography (OCT) in differentiating glaucomatous from non-glaucomatous optic nerve cupping in a cross-sectional pilot study. METHODS Eleven consecutive patients presenting to...

OBJECTIVE To compare the prevalence of structural and psychophysical abnormalities in normal eyes and eyes with glaucomatous optic neuropathy (GON) and normal standard automated perimetry (SAP). METHODS Complete examination, SAP, short-wavelength automated perimetry (SWAP), frequency doubling technology (FDT), scanning laser polarimetry (GDx-VCC), and optical coherence tomography (OCT) of the...
متن کاملEyes with Large Disc Cupping and Normal Intraocular Pressure: Using Optical Coherence Tomography to Discriminate Those With and Without Glaucoma
We evaluated the ability of spectral-domain optic coherence tomography (SD-OCT) to differentiate large physiological optic disc cupping (LPC) from glaucomatous cupping in eyes with intraocular pressure (IOP) within the normal range. We prospectively enrolled patients with glaucoma or presumed LPC. Participants had optic discs with confirmed or suspected glaucomatous damage (defined as a vertica...
متن کاملPrevalence of disc cupping in non-glaucomatous eyes.
This study assessed optic disc size and cupping, using a commercially available ophthalmoscope, in order to show norms of these values for clinical practice. Subjects were office-workers referred from their respective workplaces for a routine medical examination, which included eye examination. The optic disc size was classified as small, medium or large, for having a diameter < 1.0, 1.0-1.5, o...
