News » Senile cataract: how to recognize and deal with the problem
Senile cataract is a particular ocular degeneration condition due to the loss of the natural transparency of the lens. Very often, this opacification of the lens is still a phenomenon linked to aging, aging, which is why, in this case, which talks of senile cataracts and not simple cataracts.
With the passing of time, sometimes as early as age 50, your metabolism, renewal and growth of the cells tend to slow down, going to change over the years.
These processes may bring unwanted phenomena such as precisely as senile cataract, consisting of the loss of the perfect than natural lens function that allows you to focus on the retina objects.
Senile cataract: what are the causes?
The senile cataract, in addition to being often an event related to age, can result from trauma resulting from the presence of certain diseases - such as diabetes - or hereditary factors.
Even previous surgery of eye surgery or taking certain drugs (cortisones in particular) can cause cataracts.
The crystalline, positioned inside the eye, behind the iris, is a natural lens which allows to focus on the retina images depending on their distance.
It is a biconvex lens capable of changing the focus, thanks to the action of the ciliary body. The diseases mentioned above, and then age-related degeneration (in this case senile cataract), traumas and other pathologies, ranging precisely to interfere with the proper functioning of the crystalline andandone to undermine its natural elasticity and transparency.
Symptoms related to age-related cataract
Senile cataract presents different symptoms in view of the different states of evolution.
• At the initial stage, the cataract may not even be perceived at all.
• At the next incipient stage occurs dell\'opacizzazione increase in lens.
• At later stages, the cataract is defined brunescente. The dell\'opacizzazione intensity is such as to interfere in a manner very heavy on the normal passage of light within the eye.
Stage of evolution of cataract causes different visual symptoms, including:
• blurred mink;
• eye pain;
• increased sensitivity to light;
• greater difficulty in night vision;
• need extra illumination when reading;
• vision of yellowed or faded colors;
• loss of sensitivity to the contrast;
How and when to intervene
The speed with which it can develop senile cataract is very variable from individual to individual.
In addition, compared to other types of cataract, the latter gradually advances with a speed that in principle it is not easy to predict in advance.
If the cataract is at an early stage, the occurrence of refractive defects, such as a slight myopia or hyperopia, at least for a limited period of time, can be remedied by simply prescription eyeglasses.
In a more advanced stage, however, that when the blurred vision makes it difficult or even dangerous to carry out the same activities of daily living, which happens especially in the presence of senile cataracts, it is necessary to intervene with surgery.
The intervention in question provides for the elimination of the clouded lens, which does not allow the normal passage of light, and its replacement with a synthetic crystalline perfectly equal, but transparent.
