Epidemiological aspects, development and management of prevention in ophthalmology in relation to different ages.

In the ophthalmological field, it is not always easy to adopt a primary prevention. Much more useful would be a secondary prevention program towards the affections at birth or those later developed that, if diagnosed and treated early, grant a normal visual development. Differentiated prevention can be carried out, according to various ages: at the tender age congenital glaucoma and cataract, strabism, ametropia, anisometropia (possible cause of amblyopia) have to be considered; in the adult-senile age must be prevented damages due to hypertension, diabetes, thrombosis, as well as cataract, glaucoma, uveitis, kerato-conjunctivitis and retinal detachment.
