Aim. To study the effectiveness of antihypertensive operations of trabeculotomy ab externo and sinus trabeculoectomy in our modification in patients with congenital glaucoma and to justify its application. Methods. The following surgeries were performed: trabeculotomy ab externo - on 57 eyes of 51 patients, sinus trabeculoectomy - on 46 eyes of 42 children, classic trabeculoectomy - on 23 eyes of 19 patients, and trabeculoectomy with elements of intrascleral autodrainage in our modification - on 23 eyes of 23 patients. Among them, 22 patients were younger than 1 month, aged from 1 to 6 months - 30, from 6 months to 1 year - 18, from 1 to 3 years - 15 and from 3 to 5 years old - 8 patients. Results. Long-lasting hypotension was achieved in 86.95% of patients after sinus trabeculoectomy, in 80.39% of patients after trabeculotomy ab externo. The best results were obtained in patients younger than 6 months. In the older age groups, antihypertensive effect of trabeculotomy ab externo markedly decreased and was only 50% at the age of 3-5 years. The results after sinus trabeculoectomy were comparable in all age groups. Conclusions. Trabeculotomy ab externo can be recommended as an operation of choice during the first months of life in congenital glaucoma patients, based on the characteristics of the anterior chamber angle.

Purpose. Optimization of surgical treatment of secondary closed-angle glaucoma in patients with organic block of the anterior chamber angle. Material and methods. The analysis of the results of 6 AGO using autologous scleral drains treated with MMC is presented in children with an organic block of the anterior chamber angle without the phenomena of neovascularization is privided. Five children had uveal glaucoma; one child had an essential mesodermal iris dystrophy with secondary glaucoma. In all cases before the formation of autologous scleral drains, intraoperative applications of MMC were performed, followed by a plentiful washing of the operating field with normal saline solution. The duration of follow-up was from 1.5 to 7 years. Results. The operations proceeded without complications. There was a long choroidal edema on one eye in the early postoperative, stopped with the help of conservative treatment for 10 days. In the long term, on one eye in the period of exacerbation of uveitis, dislocation of autodrainages arose, which was facilitated by the appearance of exudative effusion in the anterior chamber. Later on this eye the failure of the AGO developed. On the other eyes, the intraocular pressure remained compensated, and the functions were stable. Conclusion. Treatment of drainages from the autosclera with MMC before implanting them into the anterior chamber of the eye, in patients with organic block of the anterior chamber angle, is effective against the hypotensive effect of the operation and is safe for intraocular structures while observing the processing technique.

Introduction. The retinopathy of prematurity (ROP) is a leading condition in the nosological structure of ophthalmic pathology in preterm children. A number of researchers note the increase in frequency of glaucoma development in such patients, considerably worsening the prognosis of the disease. At the same time, features of ocular hydrostatics and hydrodynamics taking into account the immaturity of the eye are studied insufficiently. The purpose of the study was to estimate the anterior chamber angle anatomy in preterm children with glaucoma depending on the cicatricial ROP severity. Materials and methods. The study group included 45 preterm children (87 eyes) aged from 6 months to 18 years with glaucoma on the background of cicatricial ROP. The control group consisted of 27 full-term children (54 eyes) with congenital glaucoma. As an addition to traditional ophthalmologic examination, iridocorneal goniography using a pediatric retinal camera was performed. Results. In children of the study group, anomalies of anterior chamber angle anatomic structure were diagnosed in the absolute majority of cases 97.7% of cases (85 eyes) and depended on the cicatricial ROP severity: at degrees 1-3 they were similar to those in congenital glaucoma in full-term children; at degrees 4-5 glaucoma was of secondary nature and developed as a result of a combination of dysgenesis signs in the anterior chamber angle. Conclusion. Cicatricial ROP of any degree is a high risk factor for the development of secondary glaucoma.

Purpose. The objective of the present study was to obtain and investigate the tissue samples taken from the anterior chamber angle of the children of different gestational age under the normal conditions and in the presence of congenital glaucoma; the secondary objective was to carry out the histological study of the pieces of tissues removed from the glaucoma patients of different gestational age undergoing hypotensive filtration surgery (sinusotrabeculectomy). Materials and methods. The anterior chamber angle histological preparations from a total of five enucleated eyes were available for the intravital investigation of the trabecular meshwork (two of them were obtained from the full-term infants and one from a premature baby). Results. The histological study of the structures of the anterior chamber angle of the enucleated eyes has demonstrated the presence in all the cases of cornea, Descemet’s membrane, trabecular meshwork, Schlemm’s canal, and iris. The morphological structure of the anterior chamber angle associated with congenital glaucoma shows up some peculiar features compared with the normal one, such as its block by the permanent fibrous membrane which penetrates deep into the trabecular meshwork that, in its turn, is formed from the rough and thickened tissue. The histological picture of the fetal eye at different gestational age exhibits the open anterior chamber angle, the well developed porous trabecular meshwork, and fragmentation of Descemet’s membrane near the trabecular meshwork. No signs of fibrous degeneration of the trabecule have been apparent. Conclusion. The intravital investigation of the trabecular meshwork has demonstrated some peculiar features that differ depending on the gestational age in birth. In the full-term babies, it is hypoplastic and covered with the rough fibrous membrane at certain places. Its histological picture is similar to that of the preparations of the enucleated eyes. In the premature babies, the trabecular meshwork is fibrous and characterized by enhanced cellularity; it undergoes fibrous degeneration that becomes apparent after the birth of the premature child (it is supposed to be related to the proliferative processes inherent in such babies).

Актуальность. Изменения угла передней камеры (УПК) играют ведущую роль в этиопатогенезе как врожденной глаукомы, так и глаукомы на фоне ретинопатии недоношенных (РН). Исследование параметров УПК у таких детей при помощи современных методов визуализации является актуальной задачей современной офтальмологии. Цель. Исследование УПК у детей с врожденной глаукомой и глаукомой, протекающей на фоне РН различных стадий, при помощи оптического когерентного томографа. Материал и методы. Обследованы 28 детей (33 глаза), среди которых 5 (7 глаз) – с врожденной глаукомой и 23 (26) – с глаукомой на фоне рубцового периода РН. РН II стадии была выявлена у 5 детей (7 глаз), III стадии – у 11 (11) и 7 детей (8 глаз) наблюдались с РН IVа стадии. Всем детям проводили исследование УПК с помощью оптического когерентного томографа Carl Zeiss Cirrus HD-OCT 5000 с использованием внешней линзы передней камеры. Оценивали ширину УПК и дистанцию трабекула-радужка (ДТР). Результаты. В группе детей с врожденной глаукомой средняя ширина УПК составила 47,29±11,93°, средняя ДТР – 607,14±117,57 мкм. У детей с глаукомой на фоне РН данные параметры составили, в среднем, 41,04±10,64° и 470,77±139,11 мкм соответственно. При этом наименьшие значения ширины УПК и ДТР были выявлены в группе детей с IVа стадией РН и составили 30,25±12,33° и 350±105,02 мкм. Выводы. В группе детей с глаукомой на фоне ретинопатии недоношенных отмечается уменьшение ширины УПК и дистанции трабекула-радужка по сравнению с детьми с врожденной глаукомой. Данная тенденция наиболее выражена в группе детей с IVа стадией РН, что, вероятно, обусловлено деформацией УПК в ходе выраженного экстраретинального пролиферативного процесса.
