Aim. Conduct a questionnaire survey of in private clinic patients to study the problems of ophthalmologic aid quality. Methods. The survey included 108 patients who filled in a specially designed questionnaire. Typological and variation analysis was performed, relative and mean statistical values were calculated; statistical significance of revealed differences was checked. Results. When choosing a private clinic, young people often rely on advertising, while the older patients - on the opinion of relatives and friends. Patients seek for paid services because they believe in a higher healthcare, with 59.3% of respondents believe that the quality of care is improved if they pay. Services of paid clinics are quite affordable for the majority of the interviewed patients (proposed service cost is moderate, transport accessibility, travelling time and admission queue time are quite acceptable). Generally, consumers gave a positive assessment of the clinic staff and its activities as a whole: the relationship with the doctor was characterized as trustful, attentive and respectful, involving a complete understanding of patient’s problems by the medical staff. Most respondents (92.6%) find their physician a specialist of high qualification. The main reasons for dissatisfaction with paid medical services are discrepancy between price and quality, low treatment effect, which is closely coupled with the staff competence and incorrect behavior of health workers. Conclusion. The conducted survey showed high satisfaction with medical services provided in a private clinic.

Aim. To analyze the incidence of central serous chorioretinopathy among the Kazans population between 2009 and 2018. Methods. A descriptive epidemiological study of the incidence of Central serous chorioretinopathy of the population of Kazan between 2009 and 2018 was conducted. It included an analysis of long-term changes in the incidence of male and female population and an assessment of the structure of morbidity by sex for the entire period and in dynamics. Testing for differences was performed using the nonparametric MannWhitney U test and Chi-square test with Yates correction. Results. 831 new cases of central serous chorioretinopathy were registered in Kazan during 20092018, the ratio of men and women was approximately 1:1. In the dynamics of morbidity, the proportion of men increased from 24.2% in 2009 to 60.7% in 2018 (р=0.000002), while the proportion of women decreased from 75.8% in 2009 to 39.3% in 2018 (р=0.000002). The long-term dynamics for 20092018 is characterized by a statistically significant increase in the incidence rate of central serous chorioretinopathy in men (p=0.004) from 3.2 per 100 000 in 2009 to 14.8 per 100 000 in 2018. During the study period, the incidence rate in women remains at the same level, varying from 5.4 per 100 000 to 8 per 100 000 (p=0.663). Men are more likely to have central serous chorioretinopathy at a younger age (р=0.0001). The median age at the time of diagnosis in women was 55 years (Q25Q75 4565 years), in men 45 years (Q25Q75 3756 years). Conclusion. From 2009 to 2018, the incidence rate of central serous chorioretinopathy among men in Kazan significantly increased in both intensive (p=0.004) and extensive indicators (p=0.000002); сentral serous chorioretinopathy in men develops at an earlier age compared with women (median age of women at the time of diagnosis was 55 years, median age of men 45 years, p=0.0001).
