The goal of this paper was to evaluate epidemiological data of the endocrine orbitopathy in a group of 126 patients (250 eyes) during the 5-years period (1999–2004). The prevalence of endocrine orbitopathy was at the age 46.5 ± 11.4 years, predominantly in females: 5.3 times more often than in males. In most cases (94 %) and independently on the sex, hyperthyroidism accompanied the endocrine orbitopathy. Hyperthyroidism mostly (91 %) preceded the appearance of the endocrine orbitopathy. Most patients with endocrine orbitopathy had eyelid signs (91 % females and 85 % males respectively), protrusion or exophtalmos (77 % females, 75 % males). 69% patients (68 % females, 70 % males) had elevated intraocular pressure (pseudoglaucoma, primary glaucoma). During the active stage of the endocrine orbitopathy with protrusion (52 % patients), pseudoglaucoma was detected in 7 % of patients. During the inactive stage of the endocrine orbitopathy with protrusion (34 % patients), pseudoglaucoma was detected in 4 % of patients. Primary glaucoma was found in 2 % (active stage) and 1 % (inactive astage).

        Key words: endocrine orbitopathy, epidemiological data, protrusion, intraocular pressure, pseudoglaucoma.
