2017-05-30 19:02:22 | BioPortfolio

Summary

To evaluate health related quality of life (HRQoL) of low-vision patients and their care givers undergoing low-vision rehabilitation program (LVRP).

Description

To conduct a pilot single-center, single blind longitudinal randomized controlled trial to evaluate health related quality of life (HRQoL) of low-vision patients and their care givers undergoing low-vision rehabilitation program (LVRP). LVRP includes functional vision assessments (low-vision refraction), prescription of a variety of visual aids including microscopes, magnifiers, telescopes, absorptive filters and electronic spectacle eyewear, large print books, and automatic self-transcending meditation plus essential skills for daily living and mobility training offered by Canadian National Institute for the Blind (CNIB) including demonstration of visual aids as well as training on proper use of visual aids.

Medical and Biotech [MESH] Definitions

Vision considered to be inferior to normal vision as represented by accepted standards of acuity, field of vision, or motility. Low vision generally refers to visual disorders that are caused by diseases that cannot be corrected by refraction (e.g., MACULAR DEGENERATION; RETINITIS PIGMENTOSA; DIABETIC RETINOPATHY, etc.).

Application of tests and examinations to identify visual defects or vision disorders occurring in specific populations, as in school children, the elderly, etc. It is differentiated from VISION TESTS, which are given to evaluate/measure individual visual performance not related to a specific population.

Defects of color vision are mainly hereditary traits but can be secondary to acquired or developmental abnormalities in the CONES (RETINA). Severity of hereditary defects of color vision depends on the degree of mutation of the ROD OPSINS genes (on X CHROMOSOME and CHROMOSOME 3) that code the photopigments for red, green and blue.

Type of vision test used to determine COLOR VISION DEFECTS.

Failure or imperfection of vision at night or in dim light, with good vision only on bright days. (Dorland, 27th ed)
