Keratoconus: diagnosis and cure 06 November, 2015 - Comments (0)

cheratocono Keratoconus is defined as a corneal distrophy that leads to a progressive thinning and reductionn of cornea. The keratoconus characteristic is the particular cornea shape, that becomes conical, from aspherical, and the bending becomes irregular, while it was regular, creating a such refractive variation to cause a remarkable drop of visus because it induces irregular astigmatism and shortsightedness.

The incidence on population is of 0.06%, so it means that 1 person on 2.000 can soffer from a symptomatic corneal variation.In the most of cases te distortion is not painful (unless serious complication do not appear) and it affects both the eyes , but, at times, it can happen only to one eye, this is the case in which it will be appropriate to check up periodically the contralateral eye .

Keratoconus easily appears in young age and it affects above all people of male sex.

How can we notice it?

The firs symptoms, that can induce to a keratoconus suspect, are a vision drop with our glasses linked to an astigmatism increase.

The best way to evaluate the keratoconus presence is to make a corneal topography, describing shape and dioptric power.

Which are the solutions?

A first approach to try to reconstruct a corneal surphace opticaplly smooth is through contact lenses . The reduction of optical irregularity and asymmetry it happens because the tear film situated between ephitelium and contact lens, compensates a lot of corneal irregularities, allowing a significant improving of visual quality, through a better correction of myopic defect and those astigmatic, but, above all, of the irregular element of astigmatism, typical of keratoconus.

A more significant and persistent solution is though surgery . Nowadays there is a non- invasive procedure for keratoconus cure: the corneal Cross Linking.

It is about a surgery that lasts about one hour and during which a Vitamin b2 solution is fixed on cornea surphace, after the removing of first ephitelial surphace layer, by a ultraviolet light, aimed to reconsolidate the lamellar tissues reduced by the distortion typical of this pathology.

This method tends to reduce the possibility of progression of pathology, making the surphace more regular and improving the possibility of a comfortable wear of contact lenses.

Vision as a primary necessity 06 November, 2015 - Comments (0)

visione bene primario

The eye is the sensory organ par excellance, it allows human beings and other living beings to communicate with external world: to see, as we have observed throughout history, has had a fundamental importance due to the surviving sense that throughout centuries allowed human being's evolution and his handing on what he had done for future generations, with the aim to preserve and provide that sense of continuity of species that is the basis of life's sense on this planet.

Maybe, for these reasons also, due to the deep anatomical- physiological relationship between eye - mind and brain, the sight organ has always been so fascinating, not only from a medical- scietifical point of view, but also keeping a mystical and misterious aurea.

Just think to what we can observe every day, to what we can appreciate,compare, to immediately realize how amazing the world of vision is and of what it respresents for us throughout our existence: think about the privilege of appreciate the colors, a physiological element almost exclusively reserved to mankind and only to some animal species as birds, reptiles, fishes, insects, but not to the most of mammals,included monkeys that keep a rudimental chromatic vision and for some speices is even absent.

Those remarks of general aspects should allow people to understand how precious is the seeing and how important is the protect the sight organ, with every effort, with every scientifical cognition and above all with every means, although through going out of severe and interpretative narrow mindedness of " sacred texts", that, as all the literary works written by man are the representation of mankind in a particular and precise historical moment, a static photo of that moment with all the limits and possibilieties that belonged to it. Evolution goes fast, to get adapted to modern times has become an hard and stimulating matter .
