Thyroid Function in Patients with Glaucoma

Abstract

The relationship between thyroid disorders and glaucoma is not clear. This study aimed at determining the prevalence of thyroid functional disorders in patients with glaucoma.Materials and Methods: 201 patients with glaucoma referring to Farabi Hospital were selected using simple non-random sampling. Intra ocular pressure (lOP) was measured and thyroid function tests (TFT) were done and the patients were divided into different groups according to their thyroid function status (hypo-,eu-and hyperthyroid). Results: Mean age of the patients was 54±17 years. Of the patients, 26.9% had open angle glaucoma (OAG), and the remaining had nonopen angle glaucoma (NOAG). Of 201 patients, 8 cases (4%) were hypothyroid and 17 cases (8.5%) were hyperthyroid. The mean intraocular pressures of the hypo-, eu-and hyperthroids were 18.l±9.3, 16.8±3.7 and 14.2±3.3 mmHg, respectively, which showed no significant difference. Mean lOP in patients with goiter was significantly lower than in those without goiter (16.0±5 vs.17.l±7 mmHg, p
