Possible Causes for Convergence Nystagmus

Parinaud Syndrome

Only 65.0% patients had the classical triad of vertical gaze palsy, convergence-retraction nystagmus and light-near dissociation. [ncbi.nlm.nih.gov]

The clinical features are: a loss of vertical gaze nystagmus on attempted convergence pseudo-Argyll-Robertson pupils: large pupils with sluggish reaction to light Bilateral [gpnotebook.co.uk]

Approximately 35-88% of patients will experience convergence-retraction nystagmus.[1][7] An example of convergence-retraction nystagmus can be seen at the following link. [eyewiki.aao.org]
