EDNA: Early Detection of Neovascular Age-related macular degeneration
‘Wet’ or neovascular age-related macular degeneration (nAMD) is a leading cause of sight loss in older people. The EDNA study will evaluate five non-invasive diagnostic tests which are easily performed and routinely carried out in the NHS secondary care setting and which fall into two groups: functional and morphological.
The functional tests are visual acuity, Amsler test and self-reported quality of sight. The morphological tests are fundus examination and optical coherence tomography (OCT). The diagnostic accuracy of these tests will be assessed against a reference standard test (fluorescein angiography). The results from this prospective cohort study will be used to inform the development of a decision analytic model, which will model disease progression and the costs and consequences of using the alternative diagnostic test to monitor patients in secondary care. http://www.nets.nihr.ac.uk/projects/hta/1214207.
