Automated fundus images analysis techniques to screen retinal diseases in diabetic patients

2011

In this Ph.D. thesis, we study new methods to analyse digital fundus images of diabetic patients. In particular, we concentrate on the development of the algorithmic components of an automatic screening system for diabetic retinopathy. The techniques developed can be categorized in: quality assessment and improvement, lesion segmentation and diagnosis. For the first category, we present a fast algorithm to numerically estimate the quality of a single image by employing vasculature and colour-based features; additionally, we show how it is possible to increase the image quality and remove reflection artefacts by merging information gathered in multiple fundus images (which are captured by ch…

Type 1 macular telangiectasia

2018

L’identification à l’examen clinique de petites dilatations anévrismales et d’ectasies paracentrales fait évoquer le diagnostic de télangiectasies maculaires. Celles-ci sont le plus souvent secondaires à une pathologie, notamment au diabète, aux occlusions veineuses, aux vascularites, à un néovaisseau choroïdien de type 3, etc. Le contexte et le reste de l’examen identifieront généralement l’affection primitive. Les télangiectasies maculaires de type 1 (MacTel 1) sont idiopathiques sans cause retrouvée. Ce sont des affections rares, en grande majorité unilatérales, touchant préférentiellement l’homme d’âge moyen (1).
