In a group of 50 patients with intermediary uveitis (IU) the authors evaluated the clinical finding, diagnosis with which the patients were referred to the institute and considered the problem of corticotherapy. The majority of patients was referred with a vague and inaccurate diagnosis: uveitis chronica (34%) and uveitis posterior (20%). 96% patients were treated by locally applied corticosteroids which are justified only in case of marked participation of the anterior segment of the eye. The development of posterior subcapsular cataract in 20% of the patients is according to the authors associated with overdosage of local corticotherapy. They recommend general and parabulbar corticotherapy only if cystoid oedema of the macula and oedema of the papilla develops, or in case of massive formation of an exudate on the pars plana. In patients with IU corticosteroid treatment should be indicated with great care, as complications may develop which are more serious than the disease.
