Assessment centreEye measures ⏵ Retinal optical coherence tomography


This category contains data on optical imaging (Coherence Tomography) of the retina. The instrument takes a 3D scan and photograph of the retina and also provides a magnified photograph of the fundus. This category includes data on whether the measurement was performed, and imaging data of each eye.

This measure was added to the assessment visit towards the end of recruitment and also carried out during the initial re-assessment phase in 2012 using the TOPCON 3D OCT 1000 Mk2. It was not part of the standard imaging protocol but was re-introduced at the end of 2022 for participants being re-imaged using the TOPCON Triton device.
