In 3 patients with Lafora disease specific ERGs were observed resembling closely those seen in the Schubert-Bronschein type of night blindness. In contrast to essential hemeralopia, where the b-wave is completely lacking a gradual recovery of the b-wave was recorded in Lafora disease. The recovery occurred within about 15 min of dark adaptation. ERG examinations may have diagnostic significance in patients with myoclonic epilepsy.
A hand-instrument is described, which serves the purpose of direct and indirect ophthalmoscopy. One part of the instrument, which may be used alone, is a direct ophthalmoscope; it comprises as a distinctive feature a mirror which is vertically movable. The other part is an attachment comprising magnifying lenses, a system for viewing the fundus periphery, a movable fixation target, a system for seeing the patient's eye, and a demonstration mirror. Both parts together form a light, easy-to-handle unit for monocular indirect ophthalmoscopy.
