We report a 30-year-old woman with neurocysticercosis, who showed convergence and convergence-retraction nystagmus, V-bobbing, and typical findings of pretectal syndrome due to shunt malfunction. The symptoms and signs improved with shunt revision. The co-development of convergence, convergence-evoked, and convergence-retraction nystagmus, and pretectal pseudobobbing in our patient indicates that these ocular movements may share common pathophysiology of imbalance in the vergence system.
