В связи с этим исследования в когортах достаточной численности и длительного периода наблюдения могут сыграть важную роль в предоставлении необходимой информации. Цель: изучить особенности помутнений хрусталика у облучённых лиц в отдаленные сроки после хронического радиационного воздействия с учетом влияния дозы облучения и нерадиационных факторов. В исследование были взяты пациенты из регистра облученных УНПЦ РМ, осмотренные офтальмологом в 2016-2018 гг. (всего 1377 человек). Ко всем обследованным применялась единая методика осмотра с фотофиксацией помутнений хрусталика. Исследование проводилось методом «случай – контроль». В рамках данной работы впервые были использованы индивидуализированные дозы облучения на хрусталик, рассчитанные по усовершенствованной версии дозиметрической системы TRDS-2016. В результате проведенного исследования в популяции облученных лиц, подвергшихся многолетнему воздействию ионизирующей радиации в малых дозах, установлено влияние дозы облучения на увеличение риска появления помутнений в задней капсуле и ядре хрусталика. Не получено достоверной статистической зависимости изменений хрусталика с увеличением дозы облучения в передней капсуле и корковых слоях, а также в изменении цвета ядра хрусталика. Также не доказано влияние принадлежности к разным национальным группам на приоритетное развитие помутнений в каких-либо слоях хрусталика.</p></abstract><trans-abstract xml:lang="en"><p>Up to now there is no clear understanding of health risk and type of dose dependence for the population chronically exposed within a range of low and average dose levels (to 1Gy). In this respect studies performed in cohorts with a sufficient number of persons can have a significant potential in providing necessary information. Objective: to study peculiarities of lens opacity in exposed persons at later time after chronic radiation exposure with due account for dose impact and nonradiation factors. The study includes patients from the URCRM registry of exposed population examined by an ophthalmologist in the period 2016-2018 (total 1,377 persons). The same technique of medical examination with photofixation of lens opacity was applied to all examined individuals. A case-control technique was used to conduct the study. Individual exposure doses to lens were calculated on the basis of TRDS-2016 for the first time within the framework of the present study. As a result of the performed study among persons exposed to long-term ionizing low-dose radiation we have determined an exposure dose impact on risk growth of opacity in the posterior capsule and lens nucleus. No reliable statistical dependence of lens change with an increasing exposure dose in anterior capsule and cortical layers as well as colour change of the lens nucleus was obtained. Belonging to different ethnical groups showed no impact on priority opacification development in any lens layers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ионизирующая радиация</kwd><kwd>случай – контроль</kwd><kwd>глаз</kwd><kwd>хрусталик</kwd><kwd>катаракта</kwd><kwd>малые дозы облучения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ionizing radiation</kwd><kwd>case-control</kwd><kwd>eye</kwd><kwd>lens</kwd><kwd>cataract</kwd><kwd>low-dose exposure</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Аклеев, А.В.
