[To the biometric evaluation in ophthalmoplasty].
The paper gives the preliminary results of an analysis of the metric characteristics of images in 40 patients with the anomalous outline of the lid slit of varying genesis, by applying an original computer program. The program is based on the principle of automatically finding the line of the true symmetry of the face, its paired fixed points, and the orientation of an image. Computer-aided estimation of the shape and width of the lid slit, the parameters of the lids along the conventional lines shows that the measurements are of high accuracy (0.1 mm for linear values and 0.1 for angular values). The paper analyzes the effect of modified resection of the superior tarsal muscle. In a patient with aponeurotic ptosis, the uplift of the upper lid was 4.1 mm (1.9 mm higher than that obtained by a pharmacological test). In the author's opinion, the proposed procedure makes it possible to solve the problems associated with the processing, storage, and transmission of images and with the assessment of relationships of the structures of the appendage of the eye.
