The Ductless Glands as they Appertain to Eye Diseases and to Surgery
Any one associated with a medical organization that has much to do with people who have endocrine disturbances will be impressed by the large number of such individuals who present ocular changes. In the study of these cases it becomes of increasing interest to find that these pathologic changes in the eyes not only can but must be due to the deficiencies of the internal secreting glands.
In only a few cases is it possible to identify one gland as responsible for the ocular condition, for usually more than one is causing trouble. Until better methods of study of the endocrine glands are introduced, and better surgical operations are performed on those which are at fault, disorders of the thyroid and of the pituitary will continue to be considered as the principal causes of diseases of the eye which are amenable to surgery.
In this connection, I wish to record the recent work of Dr. G. W. Crile on the suprarenals. There is a group of cases, the symptoms of which simulate those of hyperthyroidism, in which the condition is frequently called neurasthenia or neurocirculatory asthenia. In these cases the eyes may present all the changes that are associated with hyperthyroidism except exophthalmos. Such cases appear to be benefited by the denervation of the suprarenals. (As a matter of interest, it may be mentioned that studies of the ocular tension in these cases have not as yet revealed any constant rise or fall in intraocular tension.) These cases must be. . .
