Introduction

Anecdotally it is a not infrequent experience in the consulting room to find that patients possess one eye that apparently has better sight than its fellow. However, with appropriate refractive correction and in the absence of amblyopia, it has been suggested that typically this inter-eye acuity difference is small and rarely exceeds 0.10 logMAR units or one chart line (Lam et al. 1996). Nevertheless, any interocular visual acuity (VA) difference obtained under clinical circumstances might influence the interpretation of obtained acuity levels and subsequent case handling in individual circumstances.
