Study to Establish Normal Range of Binocular Single Vision Field in Asian Adults in Singapore Using Modern Assessment Techniques for Improved Eye Care

What this Trial Is About

Researchers are studying the field of binocular single vision in adults of Asian descent in Singapore to establish new normal reference values. Current standards rely on a 1974 study by Feibel & Roper-Hall, which used a small Caucasian sample, raising concerns about accuracy for the Singaporean population due to ethnic, genetic, environmental, and measurement differences over time. This research aims to update clinical benchmarks for better diagnosis and monitoring of eye conditions locally. Participants will undergo a single assessment using the Takagi MT-325UD Projection Perimeter, where they follow a moving light stimulus while indicating when they see double images. This test maps the boundaries of their binocular single vision field. The study focuses on a robust sample of 32 Asian adults from Singapore to compare their results with the old Caucasian-based standard. During one study visit lasting up to 20 minutes, participants will complete the binocular vision test, and researchers will evaluate their visual field data. The main outcome is the field of binocular single vision in the Asian population. The study will also compare these results to the existing gold standard. Participants must meet eligibility requirements and provide informed consent. The study is observational and includes safety assessments to ensure accurate data collection.
