[Use of a sclera-fortifying collagen plasty with trophic component in the treatment of high progressive myopia]. / Primenenie skleroukrepliaiushchei kollagenoplastiki s troficheskim komponentom v lechenii progressiruiushchei miopii vysokoi stepeni.

A modified scleroplastic operation is suggested, trophic collagenoplasty in which sclera-fortifying collagenoplasty is combined with subtenon implantation of a collagen infusion system. Using this system drugs stimulating trophic processes in the tissues of the posterior segment of the eyeball are infused within 7 to 9 days after surgery. Such operations were carried out in 42 eyes of 22 patients with high progressive myopia (8.0 to 27.0 diopters). The patients' ages varied from 30 to 57. Three months after surgery a manifest improvement of hydro- and hemodynamic parameters of the eyes, as well as of visual acuity with correction, of visual field, and of retinal light discriminating sensitivity were observed in the majority of patients (p < 0.05). The results of pre- and postoperative examinations demonstrate a high efficacy of such operations in patients with high progressive myopia combined with marked dystrophic changes in the tissues of the posterior segment of the eye.

[The characteristic interrelationships of the anterior chamber angle in myopia]. / Vzaimosviazi kharakteristik ugla perednei kamery pri miopii.

Comprehensive ophthalmologic examinations of the anterior chamber angle were carried out in 130 patients (259 eyes) aged 16 to 39 (mean age 22.9 +/- 0.55 years) with myopia of 0.5 to 13.6 diopters. Study of the pattern of gonioscopic signs distribution has shown that the most characteristic factor related to myopia development and progress is the presence of goniodysgenesis signs, namely, expressed development of ligamentum pectinatum iridis, marked anterior position of Schlemm's canal combined with a wide anterior chamber corner, and pigmentation of anterior chamber corner. Analysis of gonioscopic signs, their mutual influences and relationships with other anatomicofunctional parameters will help assess the role of these signs in the development of complicated myopia, prediction of myopia course, and differential diagnosis of its pathogenetic forms.
