How accurate are photographic surrogate markers used to detect macular oedema in the English National Screening Programme?

Early findings suggest that only 10% of patients with screen positive maculopathy require laser treatment. This suggests poor specificity of photographic surrogate markers which are used to predict the presence of clinically significant macular oedema.

The purpose of the audit is to determine how many patients who present with macular lesions at screening have macular oedema using optical coherence tomography as gold standard.
