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 .
