Eccentric Viewing Position as a Predictor of Potential Level of Near Visual Acuity

Kerry Fitzmaurice, HDTS DipAppSci (Orth), DOBA

The records of clients who have undergone eccentric viewing training have been used to collect the data presented in this study. Pre and post training near visual acuity measurements are presented and in each instance the degree of eccentricity of fixation is noted. Analysis of the relationship between near visual acuity and fixation distance from the fovea is discussed. Whilst there is a trend toward decreased acuity with increased distance from the fovea other factors appear to influence this relationship. The degree of eccentricity of fixation in isolation was not found to be a good predictor of post training near visual acuity. Other factors such as client age and viability of the peripheral retina appear to be better predictors of potential level of near acuity.
