The Impact of COVID-19 on Interventional Radiology Services in the UK.

Introduction: The coronavirus disease 2019 (COVID-19) has created unprecedented challenges on the healthcare system. The aim of this multi-centre study was to measure the impact of COVID-19 on IR services in the UK.

Material And Methods: Retrospective cross-sectional study of IR practice in six UK centres during the COVID-19 pandemic was carried out.

High heritability of posterior corneal tomography, as measured by Scheimpflug imaging, in a twin study.

Purpose: Anterior corneal curvature shows significant heritability. Scheimpflug imaging also permits assessment of posterior tomography. We estimated heritability of posterior and anterior tomographic parameters.
