MEN 2B is characterized by medullary carcinoma of the thyroid gland, pheochromocytoma, and mucosal neuromas. Patients with MEN 2B have enlarged corneal nerves. In addition, they often have a marfanoid habitus. Conjunctival and eyelid neuromas and keratoconjunctivitis sicca may occur. Patients with MEN 2A also have been noted to have enlarged corneal nerves. Table 8-7 lists other causes of prominent corneal nerves (Fig 8-16) from either true enlargement or increased visibility.
