Computerized static perimetry is helpful in the diagnosis of lesions of the extrabulbar afferent visual system. Especially in cases with optic neuropathies static perimetry provides some advantages over kinetic methods: Early recognition of relative defects, especially of scotomas of low density. The results of the examination are independent of the examiner, which is very important for following up the course of diseases and the evaluation of therapeutic concepts. In some cases facilitation of classification regarding pathogenesis. Disadvantages of computer-controlled automatic perimetry are: Long duration of examinations, which cannot be tolerated by all patients with neurological diseases. False positive (pathological) findings as a consequence of tiredness of the patient or inadequate conditions of investigation.
