Contrast Sensitivity Perimetry and Clinical Measures of Glaucomatous Damage

Optometry and Vision Science, Volume 91, Issue 11, Page 1302-1311, November 2014., 2014
ABSTRACT Purpose To compare conventional structural and functional measures of glaucomatous damage with a new functional measure—contrast sensitivity perimetry (CSP‐2). Methods One eye each was tested for 51 patients with glaucoma and 62 age‐similar control subjects using CSP‐2, size III 24‐2 conventional automated perimetry (CAP), 24‐2 frequency ...

Mechanisms of cone sensitivity loss in retinitis pigmentosa

Ophthalmic and Physiological Optics, Volume 44, Issue 3, Page 605-612, May 2024.
Abstract Purpose To explore the mechanisms of cone sensitivity loss in retinitis pigmentosa by combining two‐colour perimetry with threshold versus intensity (tvi) testing. Methods Seven subjects with autosomal recessive retinitis pigmentosa and 10 normal subjects were recruited and underwent perimetric testing of one eye using 480‐ and 640‐nm Goldman ...

Significance of Visual Evoked Potentials in the Assessment of Visual Field Defects in Primary Open‐Angle Glaucoma: A Review

Neuroscience Journal, Volume 2013, Issue 1, 2013., 2013
Visual evoked potentials is an important visual electrophysiological tool which has been used for the evaluation of visual field defects in primary open‐angle glaucoma and is an appropriate objective measure of optic nerve function. Significant correlations between the magnitude of the VEP parameters and MD of Humphrey static perimetry suggest that the

Beyond the Definitions of the Phenotypic Complications of Sickle Cell Disease: An Update on Management

The Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
The sickle hemoglobin is an abnormal hemoglobin due to point mutation (GAG → GTG) in exon 1 of the β globin gene resulting in the substitution of glutamic acid by valine at position 6 of the β globin polypeptide chain. Although the molecular lesion is a single‐point mutation, the sickle gene is pleiotropic in nature causing multiple phenotypic ...
