Providing Access to the Visual Environment is a pediatric low vision grant which has the ability to provide comprehensive, interdisciplinary low vision rehabilitation services to every child in Tennessee with a vision impairment. Children, ages 3-21, with best-corrected vision of 20/50 or worse in the better seeing eye are prescribed optical devices to improve their visual functioning and trained to use the devices.
Subjects are enrolled each school year based on referrals from school systems in Tennessee, ophthalmologists, and optometrists. A total of 90 new students are enrolled each year. Students are provided a comprehensive low vision rehabilitation evaluation by a low vision optometrist and prescribed optical devices to improve distance appreciation, near reading, and other tasks based on individual needs. Students are then trained to use the devices efficiently by master's level teachers of the visually impaired. The teachers travel to the students environment (school/home/work) for the training.
Variables such as ocular disease, age, visual acuity, visual improvement with optical devices, type of optical device, and reading speed are defined for each student. Providing Access to the Visual Environment also provides...

To evaluate health related quality of life (HRQoL) of low-vision patients and their care givers undergoing low-vision rehabilitation program (LVRP).
This study will determine if the interdisciplinary team low vision rehabilitation program is more effective than basic low vision care provided by an optometrist working alone in improving...

Data on the incidence of presenting vision impairment (PVI) and spectacle coverage rate (SCR) in urban China is limited.
Vision impairment (VI), including blindness, affects hundreds of millions globally, and 90% of those with VI live in low- and middle-income countries. Cross-national comparisons are important to eluci...

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)
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
