[The results of simulating congenital pathology of the extraocular muscles].

The paper describes results after calculating the distribution of tensions in the cornea in case of anomalies in the action and insertion of oculomotor muscles. The calculation was made on the basis of theories of thin coats considering the gradient of corneal thickness. By the results of the calculation, the lines of equal tensions (isochroms) were built, the forms of which is well correlated with clinical results. The calculation has shown that the rounding of one of the angles of interference rhombus and its displacement towards the centre of the picture speak about either a functional deficiency of a muscle inserted into the eye ball in this place or about displacement of the point of its insertion from the limbus along the meridian of its action; displacement of one the angles of interference rhombus from the meridian speaks about displacement of the point of efforts exertion of the corresponding muscle into the same direction. The calculation made confirms correctness of our knowledge about the nature and properties of interference pictures observed on the cornea in a polarised light.

[The diagnosis and surgical treatment of congenital convergent strabismus with a vertical component].

Examination of eyes in a polarized light in 108 children and 24 adults with congenital concomitant convergent squint with a vertical component has shown displacement of internal angles of the rhombus of interference pictures from the horizontal axis, this speaking about anomaly of internal rectus muscles insertion. The patients with congenital squint were treated by two methods proposed by the author--recession of internal rectus muscles, and in case of residual deviation--partial resection of external rectus muscles. Symmetrical position was achieved in 107 children and 21 adults; stable binocular vision could be developed only in children (25.2%).

[The surgical treatment of uveal glaucoma].

The paper describes results after surgical treatment of 17 eyes with uveal glaucoma. Since conservative treatment could not achieve normalization of intraocular pressure, the following surgical interventions were made; peripheral intralamellar iridencleisis (7 eyes), sinusotrabeculectomy with basal iridectomy (4 eyes), iridocycloretraction (2 eyes), diathermocoagulation of the ciliary body (2 eyes), drainage by a silicon tube (2 eyes). Surgical complications were hyphema in 2 eyes, injury of the lens capsule in 1 eye; in 4 eyes a slight aggravation of the uveal process after the surgery was arrested by antiinflammatory therapy. Intraocular pressure normalized in 15 eyes. Visual functions increased in patients with early diagnosed and operated glaucoma; in far-advanced cases the operation removed pains, but no functional effect was achieved.

[The administration of preparations into the vorticose vein in the combined therapy of severe forms of uveitis].

The paper describes positive results after treatment of 15 patients with severe forms of uveitis by means of administering preparations into the portal vein of the eye. The method was substantiated by a series of experimental investigations. The treatment of patients with uveitis was prescribed when common therapy within a week and in some cases--a month after beginning of treatment proved to be ineffective. In 8 eyes with endogenous uveitis visual acuity rose from 0.06 +/- 0.4 at admission to 0.28 +/- 0.7 at discharge. In 4 patients with supposed enucleation of the eye the proposed method allowed to stop the inflammatory process. This method permitted to shorten the term of the patients stay at the hospital by 6.8 days. No complications during the treatment of recurrences in remote period were recorded.
