Can DMCO Detect Visual Field Loss in Neurological Patients? A Secondary Validation Study

Unrecognized visual field loss is caused by a range of blinding eye conditions as well as serious brain diseases. The commonest cause of asymptomatic visual field loss is glaucoma. No screening tools have been proven cost-effective. Damato Multifixation Campimetry Online (DMCO), an inexpensive online test, has been evaluated as a future cost-beneficial tool to detect glaucoma. To further validate DMCO, this study aimed to test DMCO in a preselected population with neurological visual field loss.Methods: The study design was an evaluation of a diagnostic test. Patients were included if they had undergone surgery for epilepsy during 2011-2014, resulting in visual field loss. They were examined with DMCO and results were compared with those obtained with the Humphrey Field Analyzer (30:2 SITA-Fast). DMCO sensitivity and specificity were estimated with 95% confidence intervals.Results: The cohort comprised 40 patients (25 female and 15 male) with a mean age of 39 years (range 17-60 years). The mean visual acuity was>1.0 and all eyes had an intraocular pressure
