Images of the eye present the clinical with a means of diagnosing eye diseases and pathology, and following its progression.

We are using image analysis and processing tools to assist in the use of images of the cornea and retina in ophthalmology, concentrating on:

- Telemedicine

- Image compression

- Stereo-chronoscopy and Stereo-chronometry of the optic disk

- Densitometry and texture analysis of the nerve fibre layer

- Eye movements
