The Ability of Healthy Volunteers to Simulate a Neurologic Field Defect on Automated Perimetry – Corrected Proof
Objective: To determine if volunteers can simulate and reproduce 3 types of neurologic field defects: hemianopia, quadrantanopia, and central scotoma.Design: Cross-sectional study.Participants: Thirty healthy volunteers new to perimetry (including automated perimetry).Methods: After informed consent, volunteers were randomized to 1 of the 3 visual field defects listed above. All visual field testing was performed on the right eye using the Humphrey Field Analyzer (HFA; Carl Zeiss Meditec, Dublin, CA) SITA Fast 24-2 protocol. Each volunteer was provided with standard new patient instructions and was shown a diagram of the defect to be simulated. Two sets of visual fields were performed on (Read more...)
