Headache of Ocular Origin

Author and Disclosure Information


Headaches frequently are of ocular origin, and the fact that the eyes are used from 12 to 15 hours every day makes it important that, irrespective of the location of head pain or of its severity, the eyes should he examined by a competent oculist.

Very often the patients themselves are largely responsible for the incorrect diagnosis of many headaches of ocular origin. Most people do not like to wear glasses and because of the fear that they may be found necessary, important facts concerning the history of the headaches are withheld and certain symptoms which are not referable to the eyes may be emphasized in order that glasses will not be recommended. Therefore, a complete history should be elicited, and a very thorough examination should be made.

Headaches due to disturbances of the eye usually are bilateral; however, a sufficient number of unilateral headaches and pain are of eye origin that they too must be discussed.

The most important and the most severe of the unilateral causes is local inflammation which includes such conditions as iritis, iridocyclitis, choroiditis of inflammatory origin, and acute or inflammatory glaucoma. Evidence of these conditions not always is apparent, but the pain produced is severe, stabbing and boring in character. It radiates deeply through the orbit, over the side of the head, and down the neck into the shoulder. When such pain is present, the attention of an experienced oculist is required.

Spasms of the ciliary muscle may occur following thyroidectomy, during transitory hypothyroidism,. . .
