Nevrita optica

Inflamarea nervului optic poarta denumirea de nevrita optica. Boala poate cauza reducerea brusca a capacitatii vizuale.

SIMPTOME

     - pierderea sau diminuarea brusca a vederii la unul din ochi
     - schimbari ale reactiei pupilei la lumina
     - incapacitatea de a distinge culorile
     - durere la miscarea ochilor

CAUZE

Cauza nevritei optice este necunoscuta. Inflamarea brusca a nervului optic, ce face legatura intre ochi si creier, poate determina umflarea lui si distrugerea stratului extern (mielina). Inflamatia poate fi cauzata ocazional de infectii virale, boli autoimune sau scleroza multipla

TRATAMENT

De obicei, nevrita optica se vindeca singura. In anumite cazuri pentru a reduce inflamatia nervului optic, sunt administrate medicamente pe baza de steroizi. Majoritatea persoanelor isi recapata aproape integral vederea in aproximativ 6 luni.

Wholesale New Era hats celebrated 90 years as a leader in the headwear industry by teaming up
with 90 graduate artists from some of Europe's most prestigious
design schools. The artists were given a blank canvas (a blank new
era hats) and asked to unleash their creativity. The winner was awarded
£10,000 with the intent of assisting their launch into their chosen
artistic career. Throughout the month of November, all 90 works of art are
touring Europe with stops in London, Berlin, Milan, Barcelona
and Paris.

While some
pieces are very wearable, others designs take a more
creative approach. Would you wear any of the designs or do you prefer
to stick with the MLB snapbacks Hats or a New Era Snapback hats ? If you could design your own blank , what would it look like?
