The objective is to determine the frequency and clinical forms of dysthyroidian orbitopathies, in order to argue the current practical diagnostic and therapeutic attitude. A retrospective study based on the analysis of 570 patient files is conduct from 2006 to 2015, in the Ophthalmology and Metabolic and Endocrine Diseases departments of the Teaching University Hospital of Brazzaville, Congo. All patients received a complete clinical and ophthalmic examination. Patients were classified according to EUGOGO staging. The hospital frequency of dysthyroid orbitopathies was 0.3% of all patients received in ophthalmology and 1.5% in Metabolic Diseases. The results indicated that 156 patients [9 males (5.8%) and 147 females (94.2%)] with hyperthyroidism had dysthyroid orbitopathy (27.3%) and 98 exophthalmia (17.2%). The mean age was 35.5 years (range: 16-72 years). The minimal impairment was dominated (61.5% of cases), including 62 patients with exophthalmia of less than 3 mm and 32 cases with soft tissue involvement. The moderate lesion was found in 38.5%, made of palpebral retraction (24 cases) and exophthalmos greater than or equal to 3 mm (36 cases). Any severe damage did’nt observed. Therapeutically, only medical treatment has been prescribed including synthetic antithyroid drugs, local lubricants and corticosteroid therapy. In conclusion, the dysthyroid orbitopathy observed in our daily practice is dominated by minimal and moderate forms. The treatment is multidisciplinary, the therapeutic modalities obey the recommendations of the European Study Group of EUGOGO.
