Psychophysical and visual evoked potential findings in hereditary optic atrophy.

24 members of families with dominant hereditary optic atrophy were investigated. Visual acuity, Goldmann perimetry, Farnsworth-Munsell 100-hue tests, and visual evoked potentials to flash and pattern-reversal were performed. All except the Goldmann perimetry showed a significant association with the presence of optic atrophy. The flash VEP showed a positive-negative-positive response in most of the affected patients.

A controlled study of the effect of sodium valproate on photosensitive epilepsy and its prognosis.

The effect of sodium valproate on photosensitive epilepsy was studied. The range of flash rates of intermittent photic stimulation to which patients were sensitive (photosensitive range) was tested prior to treatment, and the reliability of this measure established by repeated tests on 70 patients. The photosensitive range was measured on 50 patients prior to and during treatment with sodium valproate. In 27 patients photosensitivity was abolished and in a further 12 patients photosensitivity was significantly reduced. A group of 167 patients followed without treatment did not show significant improvement over a 7 year period. Sixteen patients had drug treatment withdrawn, and in 7 months their photosensitive range had returned to its predrug level.
