[Value of the ERG in the "pattern" type (PERG) in the diagnosis of glaucoma].
The authors examined 14 persons (20 eyes) aged 51-77 years with open angle glaucoma and 3 persons (5 eyes) aged 37-59 years who were suspected for this condition. The control group consisted of 23 healthy persons (30 eyes) aged 14-40 years. The PERG results were statistically worked up using the t-Student test. Full clinical examinations and PERG were performed by means of the UTAS E-1000 system of LKC (USA) production according to modified by the authors method of May and coworkers. In the observed glaucoma group the authors revealed a statistically significant reduction of the interpeak values of the PERG in comparison with the control group; this points to a lesion of the ganglion cells in the course of this disease. The modified and adapted for the UTAS E-1000 method of May and coworkers and the applied system of conductors ensured the optimal reception of the PERG signals i.e. the maximal amplitude with minimal disturbances.
