Use of the Frostig Figure Ground in evaluation of adults with low vision.

The Frostig Figure Ground Test can be a valuable tool in the evaluation of adult low-vision patients. It is easily administered and can give valuable information about the patient's functioning. It provides an observable assessment of the individual sensory-perceptual capacities and has the further advantage of requiring the use of eye-hand coordination. Correlations of performance in this test with other data were analyzed for 79 low-vision patients. The test appears to provide some predictive information about the patient's reading performance, accounting for one-third of the variability of reading speed.

Field "expansion" by use of binocular full-field reversed 1.3X telescopic spectacles: a case report.

Full-field reversed 1.3X telescopes were used in the treatment of a 63-year-old male retinitis pigmentosa (R.P.) patient with a 5 degree central field. The patient was highly motivated to "expand" his visual field. He was trained intensively with 1.3X, 1.7X, and 2,2X reversed telescopes prior to prescribing. Evaluations by the Orientation and Mobility staff indicated significant improvements in his functioning with the devices. The reversed telescopes expanded his field to approximately 14 degrees. Patient has been reevaluated after using the aid at home and remains enthusiastic about his successful use of the aid. This case is notable in that binocular, low-power, full-field, reversed telescopes are being used successfully for mobility, eating, and other tasks.

Training and practice effects in performance with low-vision aids: a preliminary study.

Reading speed and duration were measured for 24 low vision subjects, 12 learning to use closed circuit television and 12 learning to use optical aids. Reading speed and duration increased for both groups during 10 days of training and practice. Improvement occurred by steplike increases and plateaus. Visual acuity was not correlated with either performance measure; reading speed on the initial day of training was correlated with reading speed on the last day. The results have implications for both the prescription of aids and the training of low-vision patients.
