[A method for assessing the resistance of the optic nerve to increased intraocular pressure]

The examinations have involved 62 subjects (116 eyes), of these 48 ones with open-angle glaucoma and 14 with suspected glaucoma. Vacuum compression of the eye with simultaneous recording of the visual evoked potentials (electroencephalodynamography) has been carried out. The studies have revealed increased, vs. the initial level, latent period and decreased amplitude of evoked potentials during the eye compression in 74% of patients with primary glaucoma and in 69% of subjects with suspected glaucoma. These results permit recommending electroencephalodynamography for the early diagnosis and prognosis of glaucoma.
