Retinal optical coherence tomography ⏴ Eye measures ⏴ Physical measures ⏴ Assessment centre

Description

This category contains data on optical imaging (Coherence Tomography) of the retina, using the TOPCON 3D OCT 1000 Mk2. This 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 is available for a subset of participants. Because of its size/nature, OCT data in UK Biobank will be accessed via a secure portal rather than directly exported to researchers.
