OBJECTIVE: To test if there is an association between hypothyroidism and primary open-angle glaucoma (POAG) and the utility of routine study of thyroid function in these patients. METHODS: This study was conducted in a case-control fashion. Seventy-five consecutive patients with a previous diagnosis of POAG and 75 control patients were prospectively evaluated for hypothyroidism. The levels of thyroid-stimulating hormone and free thyroxin were measured. RESULTS: Hypothyroidism was seen in only two patients with a previous diagnosis of POAG (2.67%) and in three patients in the control group (4%). CONCLUSIONS: As the authors were not able to demonstrate the previously reported relationship between hypothyroidism and POAG, they cannot recommend the systematic screening for hypothyroidism in patients with POAG.
