Cataracts are
lenses that become cloudy, so the light can not penetrate, varying in degree
from slight to total opacity. In the development of cataracts associated with
the age of the patient can cause hardening of the lens, causing sufferers
suffering from myopia, yellow to brown / white gradually and the lens opacity
can reduce the perception of blue color.
Cataracts usually progress
slowly causing vision loss and potentially blinding if cataracts are too thick.
This condition usually affects both eyes, but almost always one eye is affected
earlier than the other.
A senile cataract, which
occurs in the elderly, will first occur in the lens opacity, then the swelling
of the lens and the final shrinkage with the loss of transparency entirely. In
addition, over time the outer layer of the cataract will melt and form a milky
white liquid, which can cause severe inflammation if a lens capsule breaks and
leaks occur. When not operated, cataracts can cause glaucoma.
