Симптомы, описываемые Вами со стороны глаз, также могут быть вследствие синдрома Шегрена, при котором тиреоидные нарушения возникают у каждой третьей, среди неиммунных - гипертиреоз:

58 (36%) of the 160 patients with primary SS had evidence of thyroid disease. Autoimmune thyroid disease (ATD) was diagnosed in 32 (20%) patients and nonautoimmune thyroid disease (NATD) in 26 (16%). No significant differences were found when these prevalences were compared with those in control patients. On the other hand, comparing those patients with altered hormonal profiles, patients with NATD showed mainly hyperthyroidism (10/17, 59% versus 2/20, 10% in patients with ATD, p = 0.001)... thyroid disease occurred in more than one-third of patients with primary SS; the main cause was ATD, which was present in 20% of the patients studied.
