A comparison of Min's glasses and conventional occlusion therapy in the treatment of amblyopic children: a prospective study.
Min's glasses are specially manufactured in order to enhance the satisfaction of the wearer and increase treatment effectiveness. We compared the effectiveness of Min's glasses with that of conventional occlusion therapy in amblyopic pediatric patients. We prospectively studied 60 amblyopic patients. For four to 30 months, 24 of the patients were treated with conventional patch occlusion (patch group) and 36 of them were treated with Min's glasses (glasses group). We compared the improvement in visual acuity and the treatment compliance between both groups, according to age (over six and less than six), sex, type of amblyopia, and the duration of treatment. Sixteen patients (66.7%) in the patch group and 32 patients (88.9%) in glasses group showed improvement in visual acuity (p = 0.002). The pre-treatment average log MAR acuity was 0.56 +/- 0.25 in the patch group, and 0.59 +/- 0.25 in the glasses group. The average improvement in visual acuity was a 0.17 log MAR score in the patch group, and a 0.31 log MAR score in the glasses group (p = 0.004). Compliance was 59.54% in the patch group and 83.44% in the glasses group (p = 0.012). The pre-treatment average log MAR acuity was 0.49 +/- 0.23 for children over six years of age in the patch group, and 0.58 +/- 0.28 for children over six years of age in the glasses group. For children over six years of age in the glasses group the improvement in visual acuity (0.29 log MAR score) was greater than for children over six years of age in the patch group (0.06 log MAR score) (p = 0.0003). The pre-treatment average log MAR acuity was 0.55 +/- 0.22 for female patients in the patch group, and 0.60 +/- 0.25 for female patients in the glasses group. Female patients in the glasses group also showed a greater visual acuity improvement (0.29 log MAR score) than female patients in the patch group (0.14 log MAR score) (p = 0.0028). However, there were no differences between the groups in patients less than six years of age and in male patients. In conclusion, Min's glasses were more effective than conventional treatment with a patch in improving visual acuity and encouraging compliance in pediatric amblyopic patients, especially in children over six years of age and in girls.
