Contrast Sensitivity and Low-Contrast Visual Acuity in Children With Low Vision.

ABSTRACT:

Purpose

To investigate distance and near contrast sensitivity (CS), as well as low-contrast visual acuities (LCVAs) at 5% and 2.5% contrasts across various eye diseases causing low vision, in children aged 5 to <16 years, and to study the repeatability of these measures.

Methods

In total, 782 children (age, mean ± SD, 10.23 ± 2.75 years) with low vision, visual acuity between 0.3 and 1.3 logMAR, or visual field with mean deviation worse than 12 dB were recruited. CS was assessed with Pelli-Robson distance and near tests. Visual acuity and LCVAs at 5% and 2.5% contrast were assessed using LEA symbols. In 134 children, data were collected again in approximately 3 months for repeatability measures. Bland-Altman 95% limits of agreement (LoAs) were used to assess repeatability.
