[The syndrome of congenital unilateral hyperfunction of the inferior oblique muscle: clinico-pathogenetic variants].

Examination of 21 children with unilateral congenital paresis of superior oblique muscle and of 50 children with unilateral hyperfunction of inferior oblique muscle has shown that both forms of early squint have a picture of the same syndrome of oblique muscles disfunction as a primary congenital defect of muscular balance. A constant sign of the syndrome is unilateral hypertropia of adduction, disappearing or sharply reducing in abduction of the upward deviated eye, as well as horizontal squint of a convergent type, more frequently esotropia, nonaccommodative or partially accommodative, accompanied by a V-sign. It is proposed to name this syndrome as "syndrome of congenital unilateral hyperfunction of inferior oblique muscle".

[Morphological research on different ways of joining the rectus muscles of the eye].

The paper analyses results of comparative clinico-morphological studies of two methods for ocular rectus muscles a sutural and a loop methods used in 8 rabbits (16 eyes). Histologic examination of specimens of eye made 4-6 months after surgical intervention has shown that a loop method provides preservation of the structure of muscular tissue to a much greater degree than a sutural method. The results obtained allow to consider the loop method to be a method of choice for the usage in clinical practice as being less traumatic. The effectiveness of the operation was recorded in 15 patients with monolateral convergent paralytic strabismus. The follow-up period ranged from 6 months to 2 years.

[Elucidation of the possibilities for muscle transplantation in paralytic esotropia. Electromyography of the superior and inferior rectus muscles].

The activity of superior and inferior rectus muscles of the eye in a gaze upwards, downwards, to the right, to the left and in primary position has been electrographically determined in 13 adults without disturbances in eye motility. The analysis of the results obtained has shown that there doesn't exist adducent action of these muscles as an active physiologic function. Anatomically conditioned, but practically low and weak, adducent action of the muscles, being passive by nature, can be in norm caused by the weakening of the external rectus muscle in adduction of the eye, because in horizontal moving it preserves the level of activity characteristic for primary position of the eye. One must think that after surgical correction of paralytic esotropia by methods changing the vector of action of superior and inferior rectus muscles for restoration of adduction, the desired action of the transplanted muscles is passive and low (to 6-8 degrees).

[Syndrome of the superior oblique muscle rigidity: clinico-anatomical aspects and results of treatment of 8 patients].

Tenectomy of the superior oblique muscle resulted in complete disappearance of Brown's syndrome in 7 out of 8 children operated on. In view of this, it can be a method of choice in treatment of the syndrome. There was the first clinical case of an additional abnormal attachment of the superior oblique muscle tendon to the sclera. In another patient an abnormal marked vascularization of the tendon identified histologically had the appearance of a muscular structure at the site of the tendon seen at the operation.
