Fundus Image Analytics

Fundus photography is a standard screening tool in diagnosing retinal diseases such as diabetic retinopathy (DR) and macular degeneration. It provides a 2D image of retinal sublayers of the macular region without depth resolution, capturing gross structural changes in the oclular fundus. In fundus images, hard exudates, microaneurysms and retinal haemorrhages are some of the clinical indicators associated with various diseases. So far, clinicians employ fundus imaging for assessing these indicators qualitatively. Accordingly, various automated techniques developed for fundus imaging have also focused on detecting diseases but not a quantitative manner. In order to improve reliability of disease management, ophthalmologists seek quantitative measures of various indicators. In response, we have been working towards developing automated tools.
