Intact sensory fusion in a child with divergence paresis caused by a pontine glioma.
OBJECTIVE
To describe a child with divergence paresis esotropia caused by a brain tumor with intact sensory and motor fusion.


METHODS
Case report.


RESULTS
A 9-year-old boy who had one episode of double vision was initially seen with a small, variably present esophoria at near vision, an intermittent 10 prism diopter esotropia at distance, and stereopsis of 80 arc seconds. A magnetic resonance imaging examination disclosed a 4.0 x 4.5-cm pontine glioma.


CONCLUSIONS
Ophthalmologists should recognize that the presence of intact sensory and motor fusion in a child with acute, comitant esotropia of the divergence paresis type does not preclude intracranial abnormality. If immediate neuroimaging is deferred, repeated thorough ocular motility examinations are warranted to detect progression.
