The article provides a comparative analysis of the study of the diameter of the cornea in children with primary congenital glaucoma. Three methods, which are used in pediatric ophthalmology, are described. The first method is measuring the diameter of the cornea using a school ruler, the second method is using a surgical compass and the third is a new method developed with the use of a gauge in the form of glasses and a computer program. All the positive and negative aspects of methods for studying the diameter of the cornea are described in detail.
Purpose — to determine the values of central corneal thickness (CCT) in children depending on the level of intraocular pressure
(IOP) and the stage of congenital glaucoma (CG).
Material and methods. Clinical studies were carried out in the eye department of the clinic at the Tashkent Pediatric Medical In-
stitute. The study involved 18 patients (36 eyes) aged 9 to 11 years (mean age 9.3±1.6 years) with confirmed diagnosis of CG.
All patients underwent basic ophthalmologic examination prior to surgical and conservative treatment. In addition to basic meth-
ods, axial eye length and CCT were determined using an automatic non-contact tonometer/pachymeter manufactured by NIDEK
(USA).
Results. Analysis of the obtained data showed that in initial, moderate and advanced stages of glaucoma, the CCT values were sig-
nificantly lower than the age norm values. This indicates stretching of the fibrous capsule and thinning of the cornea in glaucoma.
In terminal stage CG, the CCT values practically did not differ from the age norm, but were higher than in initial, moderate and ad-
vanced stages of the disease. The noted thickening of the corneal membrane in terminal stage may be explained by edema of the cor-
neal tissue as a result of elevated IOP.
Conclusion. The age norm values of CCT should be taken into account when characterizing the severity of glaucomatous process
in children. Compared to the age norm, the cornea is significantly thinner in children aged 9 to 11 years with initial, moderate
and advanced stages of CG, and becomes significantly thicker in terminal stage, which is associated with edema caused by ele-
vated IOP.
Inflammatory diseases of the cornea are one of the most common causes of blindness worldwide. In recent years, many modern methods of treating diseases of the cornea have appeared, including, in addition to traditional conservative methods, modern surgical methods, such as autoconjunctival plasty, amniotic membrane transplantation, therapeutic keratoplasty, corneal covering with a corneoscleral flap, microdiathermocoagulation, and corneal crosslinking. A promising direction in the treatment of corneal pathology is stem cell therapy and cell therapy.
Determine the indicators of intraocular pressure (IOP) tonometry, taking into account the parameters of the central thickness of the cornea (CTC) in children with congenital infantile glaucoma (CIG). Clinical studies were conducted in the eye department of the Tashkent Pediatric Medical Institute's clinic. A total of 14 patients (26 eyes) aged 3 to 10 years with a diagnosis of CG were examined. All patients underwent basic ophthalmologic examination prior to surgical and conservative treatment. In addition to basic methods, the axial length of the eyeball was determined, and the CTC was determined on an automatic non-contact tonometer - Reichert pachymeter (USA). An analysis of the data showed: IOP in 39% of cases was considered subnormal, after correction taking into account the CTC in 11% of cases, the IOP was high. This group (11% of cases) was composed of children with a “thin” cornea at the terminal stage of CIG and high myopia. The correct interpretation of IOP indicators will help in choosing an adequate treatment and monitoring the glaucoma process. The used indicator of the central nervous system has practical significance in the interpretation of tonometry according to Maklakov 5 gr.

Purpose. To analyze optical and biometric indicators of children's eyes with various stages of congenital juvenile glaucoma (CJG) combined with myopia. Material and methods. We examined 17 patients (31 eyes) aged 11 to 17 (averagely 14.0 ± 0.2 years) diagnosed with CYG who underwent, prior to surgical or conservative treatment, a regular ophthalmological examination supplemented with the measurement of the central corneal thickness (on an automatic contactless tonometer-pachymeter by NIDEK, USA), and the index of corneal deformation (ICD) by the Shkrebets technique. Results. The analysis showed a possible correlation between 1) tonometric intraocular pressure (P) and the axial length of the eye, 2) P t and the ratio of excavation to optic disk diameter (E/ON), 3) axial length of the eye and the central corneal thickness at the terminal CYG stage, and 4) the axial length and the refraction at the initial stage of CYG. Conclusion. As the glaucomatous process progresses, children with CYG combined with myopia show an increase of myopic refraction, a decrease in fibrous membrane rigidity, pretrabecular and trabecular changes, axial elongation, increased IOP due to an imbalance between the production of intraocularfluid and its outflow, an expansion of the excavation of the optic disk and a decrease in the central corneal thickness.
По данным литературы, одним из самых распространенных вирусных заболеваний глаз является аденовирусный кератоконъюнктивит (АВКК). Сформировавшиеся в исходе АВКК помутнения (субэпителиальные инфильтраты) роговицы зачастую в значительной степени снижают остроту зрения и, соответственно, ухудшают качество жизни пациентов, в связи с чем важной проблемой является адекватное и эффективное лечение субэпителиальных инфильтратов роговицы после перенесенного АВКК.
This article presents the results of surgical treatment of purulent corneal ulcers in 17 patients by the method of autoconjunctival plasty in combination with tarsorraphy. The article describes in detail the technique of the operation and its main advantages. The authors have shown the effectiveness of the proposed method, which is expressed in the fact that in ease of purulent corneal ulcers, the proposed method allows you to preserve the anatomical integrity of the eyeball and improve the patient's rehabilitation process after surgery.
To determine the hydrodynamic parameters of the uninjured fellow eye of children with combined injuries of the organ of vision. A prospective analysis of the hydrodynamic parameters of the fellow eye according to Friedenwald was carried out in 18 patients (18 eyes) aged 3 to 10 years 2–3 and 45–50 days after primary surgical treatment (PSD) of a penetrating wound of the cornea, who were hospitalized in the ophthalmological department of the clinic Tashkent Pediatric Medical Institute. Group I included 8 (44%) children with the following diagnosis: “Combined injury of the organ
of vision. Contusion of the eyeball severe. Complex penetrating wound of the cornea. Group II included 10 (56%) patients with complex penetrating wounds of the cornea. 2–3 days after PST of the wound, group I showed a statistically significant increase in Pt by 2.04±0.03 mm Hg. compared with the control group, while 1–2 days after the first measurement and 45–50 days after PST, the indicators decreased, on average, by 4.4±0.02 mm Hg. without the use of antihypertensive drugs. Changes in the hydrodynamics of the eye in children of group II were not statistically significant. The results of the examination of children revealed a transient increase in tonometric intraocular pressure in the paired uninjured eye 2–3 days after PST of a penetrating wound of the cornea with combined injuries of the organ of vision.
The importance of ophthalmotonometry in the diagnosis of ocular pathology cannot be overestimated. Not you- There are doubts about the need for this study in patients of all age groups [1]. For example tonometry data in eyes with a cornea having a thickness in the center of more than 580 microns need to be corrected lowering (real IOP is lower than the obtained data) [2].
The article provides an analysis of patients in terms of frequency, causes and epidemiological features of non penetrating valved injuries of the cornea according to the data of the clinic of the Tashkent Pediatric Medical Institute. Comparative analysis of the treatment of non-penetrating valved injuries of the cornea in 24% of children who did not undergo surgical treatment, give good functional results and contribute to a more rapid restoration of visual functions.
This article focuses on the interests of international system actors in Central Asia in modern global processes, such as the United States and China. In particular, Frederick Starr's concept of "Greater Central Asia", the US Strategy for Central Asia for 2019-2025 and China's "One Place - One Way" project were analyzed.
Simblefaron is a scar fusion of the posterior conjunctival surface of the eyelid with the eyeball. It often develops as a complication of thermal burns of the eyes. Eye burns are severe damage to the organ of vision and occupy a significant share (6.9-30.5%) in the structure of eye injuries. The results of the study showed that the stage-by-stage surgical plastic surgery of the anterior segment of the eye performed by us, which consists in a combination of plastics of the fornix with flaps from the automucosal cavity of the mouth (lips) and transplantation of the amniotic membrane onto the surface of the cornea and conjunctiva with the capture of the limbal zone, allows you to eliminate the defect of the cornea and maintain its transparency and also contributes to the restoration of the conjunctival arches, which can significantly reduce the likelihood of developing complications of burn injury and shorten the rehabilitation period, improve the functional results of treatment.
The article presents the result of a survey of 35 patients after extracapsular extraction cataract with IOL implantation at the age of 8 months to 13 years.Patients underwent: viziometry, biomicroscopy, keratorefractometry, skiascopy, A, B-scan ultrasound, ophthalmoscopy, consultation of related specialists. The calculation of the optical power of IOL was performed using the SRK II formula. Refraction in the early postoperative period in children from 8 months to 6 years corresponded to the age range, from 6 to 13 years was presented in the form of ametropia.According to the authors , ametropia is a consequence of post-traumatic scarring of the cornea, tension of the stitches , swelling of the cornea and mistakes made at the calculation of the power of the IOL according to the formula SRK II.
The clinical, functional and biomechanical properties of the fibrous membrane of the eye in children with
primary congenital glaucoma were studied using the method of elastotonometry. The results of a study of the
clinical, functional and biomechanical properties of the eyes in 57 children with primary congenital glaucoma and
in 11 healthy children aged 8 days to 7 years in the eye department of the clinic of the Tashkent Pediatric Medical
Institute are analyzed. Research methods included clinical and functional methods and special (to determine the
rigidity of the membranes of the eye). The results of the study showed that with an increase in elastopod values,
the indicators of corneal deformation decrease as a result of pronounced corneal edema; the level of IOP in the
advanced and terminal stages indicates the weak rigid properties of the fibrous membrane of the eye. Thus, the
elastotonometry method is an objective quantitative diagnostic criterion for assessing the biomechanical proper-
ties of the fibrous membrane of the eye in children with congenital glaucoma.
The article presents the principles that are incorporated in the methods, as well as the methods themselves used to study the cornea: biomicroscopy, pachymetry, topographic keratotopography, optical coherence tomography, confocal microscopy and endothelial biomicroscopy. The use of traditional and modern high-tech methods of corneal examination allows for early and differential diagnosis in complex clinical cases, monitoring of treatment, as well as predicting the course and outcomes of corneal diseases
В данной научной работе изучались результаты больных с центральной серозной хориоретинопатией, которым было проведено лазерное микроимпульсное воздействие. В наше исследование было включено 39 человек, которых наблюдали в течение от 1 до 6 месяцев после проведенного лечения. Введение. По данным многих авторов и проведённых исследований, имеется множество заболеваний макулярной части сетчатки, в частности центральная серозная хориоретинопатия (ЦСХ), которые приводят к снижению остроты зрения, вплоть до слепоты. До настоящего времени причины возникновения ЦСХ окончательно не были установлены. При остром течении возникает идиопатическая отслойка нейроэпителия. Около в 80% случаев наблюдается самостоятельная резорбция субретинальной жидкости и прилегания нейроэпителия. В отличии от острой формы, хроническая форма встречается во взрослом возрасте, у лиц старше 45 лет и имеет двухсторонний процесс. Для этой формы характерно возникновение необратимых атрофических изменений в макуле и нарушения зрительных функций.
