Arteritic Anterior Ischemic Optic Neuropathy - Symptoms and Diagnosis

Symptoms and Diagnosis

There are several constitutional symptoms of temporal arteritis that may aid in diagnosis of AAION such as jaw claudication (spasms of the jaw muscle), scalp tenderness, unintentional weight loss, fatigue, myalgias and loss of appetite. However, many cases are asymptomatic. There are also elevations in three blood tests that help identify AAION: erythrocyte sedimentation rate (ESR), C reactive protein (CRP) and platelet count (thrombocytosis). A related rheumatic disease called polymyalgia rheumatica has a 15 percent incidence of giant cell arteritis.

Prompt diagnosis is critical, since the sudden blindness in the one eye is often followed, within days, by similar sudden blindness in the second eye. Treatment may prevent further damage (see below). Any patient diagnosed with non-arteritic AION over the age of 50 must be asked about the constitutional symptoms mentioned above. Furthermore, AION patients over the age of 75 should often be blood tested regardless.

Famous quotes containing the words symptoms and and/or symptoms:

    Social movements are at once the symptoms and the instruments of progress. Ignore them and statesmanship is irrelevant; fail to use them and it is weak.
    Walter Lippmann (1889–1974)

    There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.
    Karl Marx (1818–1883)
