The eye retina is the only structure in the body where vessels can be directly seen, without intrusive procedures. Imaging this structure is extremely important in the diagnosis of various pathologies, particularly diabetic retinopathy, the leading cause of avoidable blindness in the world.
Accessing the retina can be achieved through ophthalmoscopes, Optical Coherence Tomography (OCT) scans, fundus cameras, etc. The acquisition of retinal images through fundus cameras is the preferred method for the screening of common retinal pathologies. However, these devices are very expensive and tend to be bulky, limiting their use to specific places.
