The retina is the nervous tissue deputy to the visual stimulus perception. It consists of a complex network of highly organized neuronal cells. It is anatomically “hidden” and situated in back of the eye. Many diseases can affect the correct functioning of the retina. Retinal diseases can cause severe and debilitating symptoms, but some of them may go unnoticed, especially in their early stages. The Ophthalmologists can run different diagnostic tests to perform proper analysis, evaluation and appropriate management of these diseases. The Optical Coherence Tomography (OCT), the Auto Fluorescence Retinography and Computerised Visual Perimetry are the diagnostic tools most frequently used in the study and follow-up of retinal diseases.
