Abstract

The Koerber-Salus-Elschnig Sylvian aqueduct syndrome1 consists of the following findings:

1. Paresis of vertical gaze

2. Pupillary abnormalities

3. Tonic spasm of convergence on attempted upward gaze

4. Clonic convergence movements, or convergence nystagmus

5. Nystagmus retractorius

6. Vertical nystagmus on gaze up or down

7. Extraocular muscle pareses
