[Disturbances of vertical muscle function treated with a localization method]

The studies comprised 84 patients with horizontal squint and deviation of the vertical muscles and 4 children with vertical muscles disturbance, without squint while looking straight ahead. In the majority of cases, hyperfunction of the inferior oblique and inferior rectus muscles in both eyes were observed. A short treatment with hyper-corrective prisms, set with the edge in the direction of the hyperfunctional muscles was applied. In 24 persons surgical treatment allowed to settle simultaneously hyperfunction of vertical muscles and horizontal deviations.
