We report a case of Fuchs' uveitic syndrome associated with toxoplasmic chorioretinis scars, and a positive Desmonts' coefficient. This allows us to emphasize ocular toxoplasmosis as a main association to be searched for clinically. In the cases in which this association is found, it would be warranted, if a high level of specific antitoxoplasmic antibodies is demonstrated in aqueous humor, to consider toxoplasmosis as one of the potential etiopathogenic factors of the Fuchs' uveitic syndrome.
