Accommodation and convergence palsy caused by lesions in the bilateral rostral superior colliculus.
OBJECTIVE
To report a patient who developed accommodation and convergence palsy caused by lesions in the bilateral rostral superior colliculus.


METHODS
Observational case report.


METHODS
A 30-year-old right-handed man experienced sudden onset of diplopia and blurred vision at near vision.


RESULTS
The patient showed accommodation and convergence palsy. Magnetic resonance imaging revealed lesions located in the bilateral rostral superior colliculus.


CONCLUSIONS
These findings suggest that the rostral superior colliculus is involved in the control of accommodation and vergence eye movements.
