 AIM: Study of special aspects in performing and interpreting the results of OCT of the macula by ophthalmologists working in the healthcare system of the Russian Federation.
 MATERIALS AND METHODS: In the anonymous survey, conducted using an original online questionnaire of 12 questions 59 respondents took part. They confirmed being ophthalmologists with experience in performing OCT and gave their consent to took part in the survey.
 RESULTS: The majority of respondents (79.6%) reported that they face the need to perform OCT without obtaining the patients clinical data. 66.1% of respondents always evaluate the correct placement of segmentation boundaries. Only 56% of the respondents always or often perform frontal (en face) scans during OCT examination of the macula. At the same time, 16.9% of specialists indicated that they did not know what segmentation boundaries are, and 8.5% noted that they did not understand the term en face scan. The principle of layer-by-layer analysis is used by 94.9% of respondents when describing images. Significant discrepancies were also revealed in the interpretation by the respondents of some parameters on specific examples of OCT scans. 71.2% of respondents have experience in using templates when describing OCT images, and 13.6% use them constantly. The proportion of specialists who consider it expedient to develop and introduce into clinical practice a standard protocol (template) for describing macular OCT images was 84.7%.
 CONCLUSIONS: Insufficient awareness of some ophthalmologists about particular principles of interpreting the results of an OCT imaging and about certain practical aspects of its application was revealed. This indicates the need in improving the quality of informational support and training of specialists. A request was received from ophthalmologists about the need to develop a standard protocol (template) for describing OCT images of the macular area with the aim of subsequent implementation into the clinical practice of the healthcare system of the Russian Federation.","PeriodicalId":496620,"journal":{"name":"Oftalʹmologičeskie vedomosti","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136033221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Changing the geometry of polymer spherical orbital implants","authors":"Dmitry V. Davydov, Nadezda A. Baranova","doi":"10.17816/ov546107","DOIUrl":"https://doi.org/10.17816/ov546107","url":null,"abstract":"BACKGROUND: Over the past decades, various polymer implants have been actively used in the rehabilitation of patients with anophthalmos to form a volumetric support stump and improve the results of cosmetic prosthetics.
 AIM: To assess clinical symptoms and features of the X-ray picture in patients with anophthalmos after implantation of polymeric spherical endoprostheses with a modified geometry.
 MATERIALS AND METHODS: The study is based on the analysis of 30 patients with anophthalmos after enucleations (23) and eviscerations (7) performed using various methods of procedure and insertion into tissues of an implant made of domestic polytetrafluoroethylene. All patients underwent a multispiral computed tomography (MSCT) of the eye sockets according to the same algorithm.
 RESULTS: On the basis of the performed studies, the fact of making a change in the geometry of the implanted spherical implants was revealed, while the parameters of the modified part of the spheres were different and ranged from 14 to 18 mm of final diameters with the initial diameters of the spheres ranging from 18 to 20 mm. A decrease in the volume of spheres with modified geometry from 0.114 to 0.651 cm3 was revealed with initial diameters ranging from 18 to 20 mm.
 CONCLUSIONS: Changes in the geometry of the orbital spheres do not improve the results of cosmetic prosthetics in patients, increase the percentage of implant exposure at different times after surgery, and increase the manifestations of anophthalmic syndrome.","PeriodicalId":496620,"journal":{"name":"Oftalʹmologičeskie vedomosti","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135995001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
