Analysis of the records of the ophthalmologic pathoanatomic laboratory of the Kazakh Research Institute of Ophthalmic Diseases has shown that the incidence of developmental abnormalities due to disorders in the embryonal period and organogenesis have made up 3.7 percent of the total number of ocular tumors and 6.0 percent of benign tumors over the past 34 years. More than 60 percent of the patients with developmental defects were residents of South-Eastern Kazakhstan, equally frequently aborigens and representatives of other nationalities (41 and 43 patients, respectively), with male patients predominating (46 of 84 subjects). The patients' ages varied from 3 months to 70 years, children under 14 (50 patients) and young subjects aged 14 to 30 (24) prevailing. The most frequent developmental defects were dermoid cysts (61.9 percent) localized mainly in the orbit, less frequently dermoids and lipo-dermoids (20.2 percent) in the cornea, and dystrophic lacrimal gland in scleral conjunctiva (14.3 percent). Teratoma, brain hernia, and cystic eyes occurred in 1.2% of cases each; these conditions and dystopic lacrimal gland were histologically diagnosed.

[Congenital pathology of the eye as a main cause of impaired vision in children]. / Vrozhdennaia patologiia organa zreniia kak osnovnaia prichina snizheniia zreniia u detei.

Congenital diseases of the eyes is the most frequent cause of vision reduction in children and one of the major causes of invalidity for poor sight. The aim of the present study was analysis of the causes of congenital ocular diseases in children in Kazakhstan. Results of prophylactic examinations at some rural districts of the republic evidence that refraction abnormalities rank first in the structure of congenital ocular diseases, oculomotor system abnormalities second, and defects of the eyelids and lacrimal tract, third. Congenital diseases of the eye make up 29-42 percent of all ocular diseases in children. Hospital records evidence a 45 percent incidence of congenital diseases of the eye. Lenticular abnormalities rank first, oculomotor system pathology second, and eyelid diseases third in the structure of congenital diseases of the eyes.
