Generality
Vitreous detachment is a condition in which the vitreous humor - that is the gelatinous substance contained in the vitreous chamber of the eye - tends to detach from the retina, to which it adheres, withdrawing towards the center of the eyeball.
Its onset is often the result of the aging process that all human beings undergo.
Due to the high diffusion that characterizes it (N.B: it seems to affect 75% of the population over 65), vitreous detachment is not considered a real morbid condition.
However, in the presence of symptoms attributable to it, it is always advisable to contact your doctor, because (even if rarely) a macular hole or a retinal detachment could result from a detachment of the vitreous humor.
The characteristic symptoms are three: vision of "floaters" or floaters, photopsia and blurred vision.
