“…Результатом этого стало снижение остроты зрения и нарушение бинокулярных функций. С другой стороны, как показало эпидемиологическое исследование, родители детей с миопией без РН, зная о возможных рисках развития осложнений, также не выполняют назначения офтальмологов в полном объеме [26]. Но и гиперметропия, как следует из таблицы 2, являясь более физиологичным видом рефракции в детском возрасте, при наличии анизометропии и астигматизма может привести к развитию не столь грозных, но тоже неблагоприятных рефракционных осложнений, таких как амблиопия и косоглазие.…”

The improvement in nursing routine of premature babies with low and extremely low body weight has increased their survival rate. Along with the growing number of such children, retinopathy of prematurity (ROP) occurs relatively less often and its outcome becomes more favorable. Modern approaches to the surgical treatment have led to a significant reduction in the incidence of blindness and visual disability caused by ROP. Yet, ROP remains one of the major issues in neonatal ophthalmology, often associated with refractive disorders.Purpose: to evaluate the refractive changes in children with ROP after transpupillary laser coagulation of the retina based by clinical experience.Materials and methods. We analyzed 5 clinical cases of children with ROP treated in Children's City Clinical Hospital No 1 during the period from 2013 to 2014. All patients underwent retinal transpupillary laser coagulation; its volume determined by the stage of ROP. Eye refraction data were noted at the age of 1 and 7 years. The quality of visual functions and the axial length of the eye were determined at the age of 7.Results. All patients had hyperopia of varying degrees at 1 years old. By the age of 7, one patient developed myopia, another one had emmetropia, while the rest of children had hyperopia of varying degrees. Regardless of the refractive error type, the axial length of the eye remained significantly below the age norm. The low quality of visual functions is due to the lack of full-time optical correction and irregular outpatient observation.Conclusions. Most often, hyperopia refraction in children with ROP is accompanied by a short axial length of the eye. Full-time optical correction should be prescribed, and spectacle wearing should be monitored by parents and ophthalmologists who observe the patients.

Relevance. Myopia in students can lead to various problems with vision and affect quality of life and academic achievement. Aim. To analyze factors associated with the presence of myopia among medical students to develop effective methods of prevention of this disease. Materials and methods. A non-anonymous questionnaire was conducted on myopia among medical students of the first to sixth year. The questionnaire was developed based on the analysis of published data and included the demographic information, questions concerning the medical history, family history and lifestyle. The questionnaire data were supplemented with information from recording medical forms No. 025 «Medical records of patients receiving outpatient care». The data of 323 medical students were analyzed. Descriptive and logistic regression analyses were performed. Adjusted odds ratio (aOR) and 95% confidence intervals (95% CI) for each factor were calculated. Results. The median age of students was 21 years [Q1–Q3 = 19–23], min age = 17 years, max = 31 years. According to the ophthalmologist's examination, 68.7% of students had myopia (95% CI 63.4–73.7). Healthy weight and underweight were associated with the presence of myopia compared to those who are overweight or obese: aOR 2.433 (95% CI 1.096–5.403, p = 0.029) and aOR 2.774 (95% CI 1.231–6.253, p = 0.014), respectively. The presence of 8-hour sleep is associated with a decrease in the chances of having myopia by 2,321 times (aOR 0.431; 95% CI 0.190–0.979; p = 0.044). A large number of steps per day was associated with the absence of myopia. Those who walk 10,000 steps or more per day are 7.46 times less likely to have myopia than those who walk less than 2,000 steps per day. Conclusion. We report a high prevalence of myopia in medical students. The findings suggest that health promotion, including adequate sleep and regular physical activity, can be an effective strategy to prevent the occurrence or progression of myopia and other eye complications.

Relevance. Myopia is one of the most common refractive pathologies in the world. By 2050, according to WHO 2015, more than half of the world’s population will suffer from myopia, which will lead to the risk of developing pathologies associated with the progression of myopia, such as glaucoma, macular degeneration and retinal detachment. The use of various modern methods to control myopia can slow down the progression of myopia, which potentially reduces the risks of complications. Objective: to evaluate changes in the anatomical and functional parameters of the eye (clinical refraction, axial length, accommodation functions) in children with progressive myopia corrected with glasses with Stellest lenses in different age groups. Materials and methods. The study was conducted on the basis of the Eye Microsurgery Clinic of the Stavrapol State Medical University. Glasses with Stellest lenses were assigned to 80 children aged 8 to 16 years. The average age of the children was 11 ± 0.12 years. The children were divided into three age groups: 1st – primary school; 2nd -middle school; Group 3 – senior school. After the examination, the children were selected glasses with Stellest lenses. The average period of wearing glasses with Stellest lenses was 12 months. Clinical refraction, axial length and accommodation functions were evaluated during the observation. Results. The change in refraction depended on the age of the child. The greatest increase in refraction by 0.40 ± 0.02 D was observed in the younger age group, and the smallest (0.27 ± 0.02 D) in children of secondary school age. In the group of children of senior school age, the increase in refraction was +0.32 ± 0.03 D. The axial length of the eye in children of the primary school group after 12 months of wearing glasses with Stellest lenses signifi cantly increased by an average of 0.28 ± 0.03 mm. This axial growth of the eye correlates with an increase in myopic refraction in the same group of children. In the group of children of senior school age, the growth of PZO was 0.1 ± 0.04 mm. There was an increase in the accommodation reserve, the positive relative accommodation and the relative accommodation in all groups. Conclusions. The study showed that wearing glasses with Stellest lenses helps to reduce the rate of progression of myopia and increase the accommodative functions of the eye, which improves the adaptive capabilities and performance of the visual analyzer in all age groups of schoolchildren
