| Abstract: | Phasic and established visual evoked potentials (VEP) to homogeneous light field and chess patterns were studied in 25 patients (48 eyes) aged 1.5 months to 9 years with different stages of congenital glaucoma and in 114 age-matched healthy children. Patients with almost absolute and far progressed stages of the disease presented with gross changes of VEP to both large- and small-cell chess patterns. In patients with the initial stages of decompensated congenital glaucoma VEP to mostly large-cell chess patterns were altered. These data evidence the usefulness of examining the VEP to stimuli with low spatial frequency for the early detection of congenital glaucoma. |
