Late results of pleoptic treatment

Abstract

The late results of pleoptic treatment are presented in a series of 412 patients with amblyopia treated in the strabismus department of the Eye Hospital of the University of Helsinki. The result was regarded as good if visual acuity according to the Snellen chart was o 6 and vision had improved by at least IOO per cent. The series was unselected, except for the exclusion of a few cases of high anisometropia. A good primary result was obtained in 39 8 per cent. of the patients treated. In 44 per cent. of these the good vision was stable during an observation period of 2 years. Practically no relapse of amblyopia occurred after this period. A stable result was achieved in 17-5 per cent. of the whole series and a large proportion also obtained a significant improvement in visual acuity. Recurring amblyopia can usually be corrected by a further course of treatment. The authors consider that the results indicate the usefulness of pleoptic treatment in patients of school age who are suffering from amblyopia.
