| Popis: | OBJECTIVES To develop a clinical protocol for the determination of eye dominance using an objective method (i.e., the visual evoked potential [VEP]), and furthermore to determine the correlation of these objective findings with clinical subjective tests of eye dominance to provide guidance in clinical monovision refractive correction. METHODS The Diopsys NOVA-TR system was used to record the VEP amplitude and latency of 10 visually-normal, presbyopic, adult subjects aged 50 to 70 years ((Equation is included in full-text article.)=60, SEM=0.17 years). First, eye dominance was assessed in two ways: a sensory-based "sensitivity to blur task" and a motor-based "sighting task." Next, while monocularly defocused, subjects binocularly viewed a black-and-white checkerboard (20-min arc size), pattern-reversal stimulus under 7 different test conditions: (1) baseline, (2) dominant (DE) eye blurred +1 diopter (D), (3) nondominant (NDE) eye blurred +1 D, (4) DE +2 D, (5) NDE +2 D, (6) DE +3 D, and (7) NDE +3 D. RESULTS Under nearly all conditions (22/24=92%), the amplitude and latency were significantly different from baseline with any amount of defocus (P |
