*Dr. Caccamise has very generously shared his images of patients taken while operating during the "eye season" in rural India as well as those from his private practice during the 1960's and 1970's. While the quality of his images are not up to today's higher web standards, many of his images are significant for their historical perspective and for techniques and conditions seen in settings in undeveloped areas.
Graves' Disease is the most common cause of exophthalmos in adults and is often asymmetrical. The inferior rectus and medial rectus muscles are more commonly inflamed in patients with Graves' exophthalmos. The swelling of inflamed muscles leads to proptosis, and additionally may cause strabismus. Additionally, dry eye and the risk of optic nerve compression must be addressed.
In adults, bilateral exophthalmus is most often related to ophthalmic Graves' disease.

Exophthalmos: endocrine type
Congestion of the angular and temporal bulbar conjunctival blood vessels is a frequent finding in enocrine exophthalmos. It is readily evident in this photo of a patient with a thyroid gland disorder.
