Abstract:
A light-emitting diode (LED) perimeter and forced-choice procedures are described that enable quantitative assessment of peripheral visual fields of young children. The visual fields of normal children, aged 2-5 years, and adults are compared. There are no significant differences in the extent of the LED visual field of the children and the adults. For selected neuro-ophthalmology patients, results of LED and kinetic Goldmann perimetry have been compared. The patients' LED and Goldmann fields are similar in overall extent. In all cases, field defects demonstrated by Goldmann perimetry are detected by LED perimetry. However, discrepancies in the severity of quandrantanopic defects of a patient have been discovered that may be stimulus-dependent.
