An Early Prospective Study of the Traq™ Device for Characterization of Binocular Ocular Function in Normal Subjects and Subjects With Recent Traumatic Brain Injury

The early prospective study of Traq™ (an investigational binocular ophthalmic neurodiagnostic device) will measure binocular ocular functions (bilateral foveal fixation, foveal binocularity, and fovea-tracked saccadic latency) in normal subjects and those with history of mild-to moderate traumatic brain injury (mTBI).

Pilot Study of Normative Range of Field of Binocular Single Vision in Adults in Singapore

The assessment and monitoring of the field of binocular single vision remains a crucial aspect of ophthalmological care, yet current clinical practice relies on normative standards established by Feibel \& Roper-Hall in 1974 that present significant limitations for contemporary application. The original study, conducted with a demographically homogeneous Caucasian population in St Louis using only "several" normal individuals, raises concerns regarding its applicability to Asian populations, particularly in Singapore, where ethnic and genetic factors may influence ocular characteristics. The limited sample size significantly increases the likelihood of Type II errors, whilst the temporal gap of over five decades introduces additional concerns regarding population changes, environmental factors, and advances in measurement techniques that have not been incorporated into current normative data. Given these substantial limitations in demographic representation, statistical power, and temporal relevance, there exists a pressing need to establish population-specific normative data for the field of binocular single vision in Singapore's adult population, which would provide more clinically relevant reference values and potentially improve diagnostic accuracy for ocular conditions in the local context.
