[Tenoplasty by marginal scleral division (author's transl)].
The author proposes a new technique consisting of lengthening the tendon of the hyperactive muscle by means of two small superficial scleral longues positioned at two extremities of the insertion, each being 1.5 to 2 mm in width and having a length that varies according th the degree of deviation to be corrected. The tendon is cut level with the sclera, between the two scleral tongues. Results in 27 cases were favorable (residual deviation of less than 10 degrees) in 70 p. cent of cases after one tenoplasty operation and 85 p. cent after a repeat tenoplasty. The length of the tenoplasty and the effect obtained vary with the type of strabismus: for each millimetre of tenoplasty the resulting correction is 2.2 degrees in monocular strabismus, 2.7 degrees in alternating strabismus, and 3.3 degrees in residual strabismus.
