We wish to evaluate a potential training program for patients with glaucoma, to become more efficient users of prescribed low vision devices for distance and near vision tasks. We hypothesize that the devices will improve efficiency. Prescribed devices will include a stand magnifier, a handheld magnifier, spectacle magnifiers for near vision, and a handheld monocular (telescope) and a bioptic telescope (spectacle-mounted telescope) for distance vision. The success of being able to use optical devices is dependent upon training. Optical devices are currently accepted and used for patients with visual conditions that decrease their central vision. The bioptic telescope is a pair of glasses with a small telescope mounted within the carrier lens. The glasses look and feel like a normal pair of glasses, but have a black device (telescope) protruding from the top of one lens for better identifying distance objects. The spectacle magnifier is mounted in a pair of glasses also for near vision
You will be asked a series of oral questions regarding your health status and vision level of functioning (Expectations of Visual Functioning Form, NEI-VFQ, Linear Rating Scale, and Geriatric Depression Scale) in the Vanderbilt Eye Clinic. You will undergo a mobility pre-test to assess your ability to find objects in the distance as well as read . You will undergo a low vision examination in the eye clinic. You will receive the optical devices and then receive brief instructions on the use of the devices . You will then undergo a pre-training evaluation. You will receive approximately 6 training sessions with your prescribed devices for up to 1 hour each time. You will return to the Vanderbilt Eye Clinic for the post-training distance and near vision assessments with the devices . You will be asked the series of oral questions again regarding your health status and vision level of functioning .

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)
