[Ocular toxoplasmosis in 1989].

The clinical aspect of congenital toxoplasmosis is sometimes typical, sometimes atypical. The advantage of the serological study of the aqueous is an early diagnosis and an early treatment for less expense. The classical treatment relies on the therapeutic association Pyrimethamine + Adiazine + corticosteroids which will be used during acute phases, at ordinary doses, but may be prolonged further over many months in difficult cases. Severe forms are those that are spontaneously severe or increased with the exclusive use of corticosteroids in previous attacks, noticeably when injected by local route, and in bilateral forms. Prevention of ocular toxoplasmosis is represented by the detection of sero-conversion in mother and treatment in the newborn. Due to the legal aspect of this procedure in France, the incidence of congenital toxoplasmosis has already decreased during the past years and will continue to diminish in the next future. However the possibility of acquired forms cannot be excluded, even in non immuno-depressed patients.
