VA: 20/15 OU; Normal color vision; RAPD OD and fundus exam was normal. Discs were cupless, + SVP OU, flat with abundant NFL OU. Automated visual fields were full, and a PVER was normal OU. Versions were full; pursuit was interrupted by nystagmus. Saccades were rapid vertically and horizontally. A moderately large amplitude downbeating nystagmus was present in primary position, increased in amplitude on eccentric viewing, and had similar quality in all positions of downgaze. In straight upgaze the nystagmus continued with the same amplitude and direction but significantly lessened in amplitude in gaze to up and right and to up and left. A 3 pd right hypertropia was present in right gaze with a 1 pd LHT in left gaze. Brain MRI (8-8-02) revealed an extensive multilobulated cystic mass lying ventral to and within the 4th ventricle and involving the entire midbrain pretectum and tegmentum. |
