[Convergence insufficiency and school difficulties (author's transl)].
124 lowgrade hypermetropic pupils aged from 6 to 9 years, with normal I.Q. showed exophoria for near vision combined with weakness of convergence and school difficulties in several disciplines. These were treated as follows: training of the physiological diplopy, training of convergence, and surgical treatment by unilateral or bilateral resection of the medial rectus (the last-mentioned method has been applied on failure of so-called "ophthalmologic home-work"). Results were satisfactory in only 19%. The subjective primary complaints, similar to asthenopy, disappeared within a few weeks (65%). The effect of ophthalmological treatment was examined by the school psychological service as to acceleration in learning. Supported by comparisable objective effects (reading- and writing tests) with 50 control persons an improvement of concentration and motivation (77% and 62%), of reading capacity (44%) and of writing capacity (42%) was obtained within a space of 6 weeks to four months. Without taking up a too great percentage of the available school time, more attention should be paid in the elementary school age to a more accurate examination of the eyes, in order to detect even minor defects.
