Central corneal thickness. Ocular correlations in normal eyes and those with primary angle-closure glaucoma.
In recent papers (Lowe, I968, I969a) it was shown that in normal eyes, lens position and thickness were coordinated with axial length and radius of corneal curvature, whereas in eyes with primary angle-closure glaucoma these correlations were lacking. Throughout adult life, lenses increase in thickness at the same rate in normal eyes and those with angle-closure glaucoma, but no change could be...
متن کاملComparison of optic nerve imaging methods to distinguish normal eyes from those with glaucoma.
PURPOSE To compare the ability of qualitative assessment of optic nerve head stereophotographs (ONHPs), confocal scanning laser ophthalmoscopy (CSLO), scanning laser polarimetry (SLP), and optical coherence tomography (OCT) to distinguish normal eyes from those with early to moderate glaucomatous visual field defects. METHODS Eighty-nine eyes (63 normal, 63 age-matched with glaucoma) of 89 su...
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.â we prospectively enrolled patients with glaucoma or presumed lpc. participants â had optic discs with confirmed or suspected glaucomatous damage (defined as a ver...
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 کاملEvolving eyes.
Despite the incredible diversity among extant eyes, laws of physics constrain how light can be collected resulting in only eight known optical systems in animal eyes. Surprisingly, all animal eyes share a common molecular strategy using opsin for catching photons, but there are a diverse collection of mechanisms with proteins unrelated to each other used to focus light for vision. However, opsi...
