Psychophysical testing in glaucoma.
Glaucoma can be diagnosed as a group of conditions that share a characteristic topographic change at the optic nerve head (glaucomatous cupping) and pattern of visual loss (glaucomatous visual field defect). Usually the intraocular pressure (IOP) lies above the normal range. For a common complaint, the existence of which has been known for centuries, we ophthalmologists are not good at identify...
متن کاملPsychophysical and electrophysiological testing in ocular hypertension.
PURPOSE The purpose of this study was to compare psychophysical and electrophysiological testings in early optic nerve dysfunction in a group of clinically asymptomatic subjects with suspect ocular hypertension (OHT). METHODS Forty eyes of 40 patients with suspect OHT and asymmetrical horizontal cup/disc ratio (0.2/0.4), 22 eyes of 22 patients with open-angle glaucoma (OAG), and 40 eyes of 40...
متن کاملRelationship between electrophysiological, psychophysical, and anatomical measurements in glaucoma.
PURPOSE To evaluate the relationship between electrophysiological, psychophysical, and structural measurements in normal and glaucomatous eyes and to test the hypothesis that there is a continuous structure-function relationship between ganglion cell numbers and visual field sensitivity. METHODS Thirty-four normal subjects and 40 patients with glaucoma were examined with the pattern electrore...
متن کاملPsychophysical Detection Testing with Bayesian Active Learning
Psychophysical detection tests are ubiquitous in the study of human sensation and the diagnosis and treatment of virtually all sensory impairments. In many of these settings, the goal is to recover, from a series of binary observations from a human subject, the latent function that describes the discriminability of a sensory stimulus over some relevant domain. The auditory detection test, for e...
متن کاملTesting Contextuality in Cyclic Psychophysical Systems of High Ranks
Contextuality-by-Default (CbD) is a mathematical framework for understanding the role of context in systems with deterministic inputs and random outputs. A necessary and sufficient condition for contextuality was derived for cyclic systems with binary outcomes. In quantum physics, the cyclic systems of ranks n = 5, 4, and 3 are known as systems of Klyachko-type, EPR-Bell-type, and Leggett-Garg-...
