Treatment of astigmatism-related amblyopia in 3-to 5-year-old children

Best-corrected acuity was measured for vertical and horizontal gratings and for Lea Symbols(R) recognition acuity in 3- to 5-year-old children with high astigmatism and in non-astigmatic children. There was significant amblyopia among astigmatic children at baseline. There was no evidence that eyeglass correction of astigmatism resulted in a reduction in amblyopia over a 4-month average treatment duration (although vision in astigmatic children was significantly improved immediately upon eyeglass correction, indicating that eyeglass correction did provide a visual benefit). Treatment outcome results are discussed in terms of both methodological issues and theoretical implications. (C) 2004 Elsevier Ltd. All rights reserved.
