The function of the choroid, the middle layer of the eye globe, is to provide metabolic needs to the retina and to regulate ocular pressure and temperature. The vascular nature of the choroid makes the variations of its thickness an indication for the ocular health. Pathologies such as retinitis pigmentosa, serous chorioretinopathy, diabetic retinopathy and others cause thickening of the choroid, while its narrowing is associated with myopia, dehydration or age.

The imaging method used in this project is the EDI-OCT (Enhanced Depth Imaging – Optical Coherence Tomography), a non-invasive, non-painful and fast imaging technique that allows a good visualization of the choroidal tissue.

Main Task Goals:

To develop software tools to automatically calculate and mapping the choroidal thickness in the eye globe.
