Vision Disorders - Physiopathology
Research News and Information
Definition of 'Vision Disorders'Visual impairments limiting one or more of the basic functions of the eye: visual acuity, dark adaptation, color vision, or peripheral vision. These may result from EYE DISEASES; OPTIC NERVE DISEASES; VISUAL PATHWAY diseases; OCCIPITAL LOBE diseases; OCULAR MOTILITY DISORDERS; and other conditions. Visual disability refers to inability of the individual to perform specific visual tasks, such as reading, writing, orientation, or traveling unaided.

OBJECTIVES: To compare the retinal nerve fiber layer (RNFL) thickness and retinal sensitivity in the normal visual hemifield of glaucomatous eyes with localized visual field loss with those of normal eyes and eyes with suspected glaucoma, and to ... Read more...
Visual impairment in the absence of dystroglycan.
19 Oct 2009 Ocular involvement in muscular dystrophy ranges from structural defects to abnormal electroretinograms. While the mechanisms underlying the abnormal retinal physiology in patients are not understood, it is thought that alpha-dystroglycan ... Read more...
Prediction of functional loss in glaucoma from progressive optic disc damage.
29 Sep 2009 OBJECTIVE: To evaluate the ability of progressive optic disc damage detected by assessment of longitudinal stereophotographs to predict future development of functional loss in those with suspected glaucoma. METHODS: The study included 639 eyes of ... Read more...
