| Research Abstract |
Thirty-six patients with advanced glaucoma under 70 years old and 36 age- and driving exposure time-matched normal subjects underwent the driving simulator (DS) and standard automated perimetry with the Humphrey 24-2 Swedish Interactive Threshold Algorithm(HFA 24-2). The binocular integrated visual field(IVF) was calculated by merging the two results from the monocular HFA 24-2 test, using the patients' best point-by-point monocular sensitivity.
Four of 14 scenarios showed a significant difference in the incidence of collision between the advanced glaucoma and normal control groups. IVF sensitivity was lower in specific visual subfields in the collision-involved glaucoma patients, than in the collision-uninvolved patients. We establish methods to determine the relationship between different types and degrees of visual field impairment and MVA involvement by examining the incidence of collisions by test subjects in a DS.
