Цель. Ознакомить врачей-офтальмологов и оптометристов с основами корнеотопографии  – важным методом оценки регулярности поверхности роговицы, нарушение которой приводит к ухудшению преломляющих свойств роговицы и снижению качества зрения. В первой части практикума (The EYE ГЛАЗ. 2020 (22), № 2) были представлены основные типы топографических карт и кератометрические данные. Во второй части предложены рекомендации по приобретению навыков получения качественных снимков, выбору цветовых карт для анализа, топографические паттерны в  норме и при патологии, а также топографические признаки кератоконуса. Заключение. Устройства на основе диска Placido  – полезный инструмент для оценки передней поверхности роговицы, подбора контактных линз и диагностики кератоконуса. Топографы на основе щелевого сканирования дополнительно дают представление о пахиметрии и задней поверхности роговицы, что позволяет провести экспертную оценку в диагностике кератоконуса на доклинической стадии.

Goal. To introduce ophthalmologists and optometrists to the basics of corneal topography. Corneal topography is the main method for assessing corneal surface regularity, the violation of which leads to a deterioration in its refractive properties and a decrease in the quality of vision. The first part of the workshop (The EYE GLAZ. 2020 (22), № 2) presented the main types of topography maps and keratometry data. In the second part, considerations are made regarding mastering the skills of capturing high-quality images and choice of color maps for analysis. Topography patterns as well as topographic signs of keratoconus are also discussed. Conclusion. Placido-based corneal topographers are a useful tool for evaluating the anterior corneal surface, fitting contact lenses and diagnosing keratoconus. Slit-scanning topographers, additionally, are capable of corneal pachymetry and analyzing the posterior surface of the cornea, which allows for carrying out a more detailed assessment and diagnosing keratoconus at preclinical stage.
