What is the leading cause of blindness?

Hacer frente a la ceguera: los hechos

Ser capaz de leer y escribir es de gran importancia para la sociedad. Una persona con una discapacidad visual es considerada analfabeta si él o ella no puede leer en braille, de acuerdo a la definición. Las estadísticas fueron tomadas del Instituto Braille. Debido a la importancia de la alfabetización, el Instituto Braille dedica gran parte de sus recursos para ayudar a aumentar la alfabetización en Braille en la comunidad de ciegos. El noventa por ciento de los empleados que ocupan puestos ciegos en los Estados Unidos son en Braille leer y escribir. Treinta y tres estados han promulgado leyes que promuevan la enseñanza del sistema Braille en la escuela (grados K-12).

Una persona se considera legalmente ciega si? Su agudeza de la visión central es de 20/200 o menos en el mejor ojo, aún con lentes correctoras.? Si la agudeza de la visión central es más de 20/200, pero el campo periférico es? Limitarse a un diámetro de 20 grados o menos,? Una persona se considera legalmente ciego.

Alrededor de 7,3 millones de euros (alrededor de 25 por ciento de la población) personas mayores de 65 años tienen algún tipo de trastorno de la visión. Los diabéticos son 25 tiempo más probabilidades de quedar ciego que los no diabéticos. En los Estados Unidos, hay 15 millones de personas que son ciegas o tienen algún trastorno de la visión de otros.

Las mujeres viven más que los hombres, las estadísticas de deterioro tan visuales están sobrerrepresentados en favor o en las mujeres. Uno de cada 20 niños en edad preescolar (de 3 a 5) se ve afectada por problemas de visión. Alrededor del 25 por ciento de los niños en edad escolar (6 a 17) los niños se ven afectados por problemas de visión. Setenta por ciento de las personas ciegas o deficientes visuales graves tienen más de 65 años, y de ese grupo, 50 por ciento son legalmente ciegos.

Existen ayudas para los ciegos y deficientes visuales, pero no muchas personas ciegas hacen uso de estas ayudas? Sólo el 2 por ciento de las personas legalmente ciegas utilizar un perro guía y un 35 por ciento el uso de un bastón blanco.

Las principales causas de ceguera son la edad de la degeneración macular relacionada con el glaucoma, la retinopatía diabética y las cataratas relacionadas con la edad.
