Heads: P. Brrendstrup and M . S . Norn) ENDOGENOUS UVElTlS II. Recurrence Rate BY M. S. NORNAt the onset of the first attack of uveitis it may be difficult or impossible to make a prognosis. An apparently mild iritis may in the course of a few days develop into severe fibrinous iritis, or it may preserve its mild form, but then run a prolonged course.In other cases, where, perhaps, a long series of examinations have been started immediately after the diagnosis has been made, the mild iritis is seen to subside and the eye to have recovered before any results of the examinations have been achieved.The clinical picture of uveitis can give certain prognostic hints. A nodose uveitis is taken to have a poorer prognosis than a non-nodose. Fibrinous iritis tends to run a shorter course.The different forms of uveitis show a tendency to recurrence. The recurrence rate seems to depend on the type of uveitis.Vesterdal found fibrinous iritis to be the most frequently recurring type (in 58 per cent), while subacute iritis recurred in fewer cases (37 per cent), and choroiditis in still fewer (28 per cent). Her total series comprised 350 patients.Leira employed a different clinical classification of his series of endogenous, non-purulent, ocular inflammation, including 252 cases of proper uveitis.H e noticed recurrence in no less than 82 per cent of the cases of acute iritis with associated spondylarthritis anchylopoietica (Bechterew), in 60 per cent of the group comprising chronic iritis and choroiditis, and in only 48 per cent of the cases of acute iritis without spondylitis.
