  • Title: [Role of biopotentials of the retina in the study of mechanisms of the development of nystagmus].
    Author: Shamshinova AM, Snol'ianinova IL, Mats KA, Basova EL.
    Journal: Vestn Oftalmol; 1991; 107(6):46-50. PubMed ID: 1781125.
    Abstract:
    Total and local electroretinograms were studied simultaneously with registration of visual evoked potentials in 174 patients with nystagmus without pathologic shifts in the anterior section of the eyeball. Clinical and electrophysiologic findings permitting dividing the patients with nystagmus into two groups with different prognosis of the disease course: that without apparent changes in the fundus oculi with normal and subnormal parameters of the total and local ERG and that with pathologic changes in the retina and optic nerve and the corresponding electrophysiologic symptoms. Central mechanisms of nystagmus origin may be supposed in Group 1; visual function improved after pleoptic treatment. In Group 2 sensory mechanisms of nystagmus development are possible; visual functions did not improve after therapy. The mechanisms of vision deterioration in nystagmus are to be studied.
