The treatment of congenital idiopathic nystagmus by intermittent photic stimulation

An analysis is presented of the results obtained by treating 54 patients with congenital nystagmus using intermittent photic stimulation. The major beneficial effect has been to improve the visual acuity, though the nystagmus itself is sometimes reduced in amplitude or even eliminated; an unexpected bonus, in certain cases, is the improvement in stereoscopic acuity.
