Objective: The present study is to develop and evaluate an ergonomic gaze fixation induction method for applying a visual field testing system. Background: Glaucoma which is progressive visual field defects in the ophthalmology has been screened by visual field examination. For accurate visual field testing result, it is important to fix a patient’s line of sight to a center point on visual field testing area. However, the existing visual field tester’s reliability is low because there is lack of inducing patient gaze fixation. Apparatus: To conduct the gaze fixation performance testing, the present study used a PC monitor, an input keypad, and a chin support and a visual field testing S/W applied with 24-2 threshold method (Paolo, 2006). 1<SUP>st</SUP> pilot test: The result of eye fixation performance and subjective satisfaction (7-point scale) for eye fixation targets applied with different color, alphanumeric, and shape showed no significances. 2<SUP>nd</SUP> pilot test: 5 and 10 Hz flashing dots of 0, 1, 5, and 10 Hz flashing dots as eye fixation targets had better subjective satisfactions (3-point scale) than those of the remainder. Final test: Eye fixation targets applying flash rate and shape factor including previous eye fixation targets (reference dot and flashing dot) are to be evaluated for the eye fixation performance (fixation error rate, fixation loss rate) and subjective satisfaction (easy gaze fixation, testing concentration, eye fatigue, and overall satisfaction) on 40 people (20 ~ 70 age groups). Conclusion: The flashing dot was the best gaze fixation for high testing accuracy during visual field testing. Application: The ergonomic gaze fixation induction method is expected to be used for glaucoma diagnosis with visual field examination.
