研究目的
To examine changes in ?xation stability over time during binocular and monocular viewing in patients with age-related macular degeneration (AMD).
研究成果
In patients with AMD, fixation stability stays constant over consecutive time intervals during binocular and monocular viewing with the better eye. Monocular fixational control with the worse eye is poor, but improves over time, suggesting highly adaptive ocular motor control.
研究不足
Results may have been influenced by age differences between the AMD group and the control group. Technological limitations have prevented the study of the PRL location during binocular viewing concurrently for the two eyes to a great extent.
1：Experimental Design and Method Selection:
The study involved recording fixation stability using an EyeLink eyetracker during binocular and monocular viewing conditions.
2：Sample Selection and Data Sources:
Seventeen patients with AMD and 17 controls were enrolled.
3：List of Experimental Equipment and Materials:
EyeLink 1000 eye-tracker (SR Research Ltd.), Samsung monitor (Sync Master 900 NF), IR filters (Kodak Wratten 87 IR).
4：Experimental Procedures and Operational Workflow:
Fixation stability was recorded for 15 s under binocular and monocular viewing conditions, with the fellow eye covered.
5：Data Analysis Methods:
Fixation stability was analyzed using a 68% bivariate contour ellipse area over 3 s intervals.
