This research briefing presents the findings from analysis of the CVI data in England and Wales covering the period 2012 to 2013. The briefing is the fifth in a series of reports examining CVI data. The research is part of an RNIB research grant awarded to Moorfields Eye Hospital to support the ongoing analysis of CVI data.
The Certifications Office, based at Moorfields Eye Hospital in London, undertakes annual collection and analysis of epidemiological data contained on the CVI form. The work is conducted under the auspices of the Royal College of Ophthalmologists.
