The Damato Multifixation Campimetry Online (DMCO) – A possible visual field test to detect neurological visual field defects

PurposeThe aim of the present study is to determine the ability of DMCO to detect visual field (VF) loss after epilepsy surgery and to determine the risk of visual field defects related to the operation.MethodsSixty patients will be tested by DMCO and Humphrey VF Analyzer (HFA). The patients will get a full eye examination to exclude eye diseases. A questionnaire will determine the subjective claims from the patients.Results16 DT Standard tests have been performed on ten eyes. HFA found that two patients had an almost complete quadrant anopsia, two had a smaller degree of quadrant anopsia, and one had no VF loss. DMCO detected the VF defect in the two patients with almost complete quadrant anopsia and not in the patients with the smaller VF loss. None of the patients perceived their VF loss before the test.ConclusionsThe preliminary results indicate an eighty percent risk of VF loss after epilepsy surgery. Our study indicates that DMCO may be a useful tool to detect neurological unrecognized VF losses.
