Age Related Diseases of the Human Retina

It is very common to encounter senile lesions of the eyes and therefore a reduction in the acuity of vision and also peripheral chorioretinal lesions, which cause severe retinal lesions such as senile retinal detachment. The interest in studying geriatric changes to vision lies in identifying the first lesions as early as possible. Not that it is possible, at least up to now, to impede the inexorable evolution of the degenerative phenomena, but an early diagnosis can at least allow us to greatly slow this process. With the passing of the years, the normal architecture of the retina undergoes modifications starting from the ora serata toward the posterior pole for a variable distance. At the posterior pole of the Bruch's membrane (drusen), lipid or calcium carbonate soap deposits and capillarosis (obliterated aneurisms) are seen. Dry and wet macular degeneration are clinical pictures often discussed in pathology. Finally, the cystoids of the macula begin with an edema with brilliant irregular foveal reflexes, which surround the macula. In the macula there may be an isolated vesicle, dark red in color, with sharply defined edges. In the periphery, the most frequent lesions are cystic degeneration and Blessig-Iwanoff holes, localized in the ora serrata (Owsley et al., 2000).
