The proximal and distal click syndrome of the superior oblique tendon.

In the following case report we describe a healthy 25-year-old woman suffering from the "click" syndrome with pseudoparesis of the superior oblique muscle and a concomitant inflammatory ocular disorder. No etiology of the chorioretinitic changes or click syndrome could be ascertained. Based on the different topographic conditions present, we suggest the introduction of two new subgroups involving a proximal and a distal click syndrome.
