[Evaluation of the effect of Snyder-Thompson scleroplasty based on the behavior of the axial dimension of the eye ball].

A trial of evaluation of the effectiveness and durability of the effects of the surgical technique performed on the basis of the behaviour of the antero-posterior axial dimensions of the eye. Observations concerned 75 persons (129 eyes), the control group consisted of 20 persons (40 eyes) treated conservatively. Evaluating the dynamics of the pathological process in persons treated conservatively one found a considerable increase of the eye ball. In a similar time 12 months examinations carried out on the operated eyes showed statistically essential shortening of the axis of the eyes and in the time of subsequent controls (1-1.5 years after surgery) their slight elongation. The last control (after 5 years) showed a still persisting, statistically essential shortening of the eye, on the average 0.22 mm, in relation to the measurements taken before the scleroplasty.
