Misdiagnosis and Myopia

Untreated patients of Marfan's die at age 30: Marfan's syndrome is an autosomal disorder of the connective tissues. It affects the connective tissue of the skeletal, ocular and cardiovascular system. The patient is usually tall and thin with long digits, high arched palate and loose joints. He may also present with ocular and cardiac deformities. The diagnosis is based on the family history and co-relating all the findings. Of concern is aortic root dilatation which occurs in these patients and hence an annual echocardiogram is required. It must be discriminated from acromegaly, gigantism, fragile X syndrome and thyrotoxicosis by means of blood investigations. If untreated the patient dies at the age of 30 or 40 years. Genetic counselling for the family is needed....read more »

Article Excerpts about Myopia

When the cornea is curved too much, or if the eye is too long, faraway objects will appear blurry because they are focused in front of the retina. This is called myopia, or nearsightedness. Myopia affects over 25 percent of all adult Americans. (Source: excerpt from Facts About the Cornea and Corneal Disease: NEI)

Definitions of Myopia:

A refractive error in which rays of light entering the eye parallel to the optic axis are brought to a focus in front of the retina, as a result of the eyeball being too long from front to back; also called nearsightedness because the near point is less distant than it is in emmetropia with an equal amplitude of accommodation. - (Source - Diseases Database)

(ophthalmology) eyesight abnormality resulting from the eye's faulty refractive ability; distant objects appear blurred - (Source - WordNet 2.1)
