Acute comitant esotropia in a very young child due to combined mechanism: A case report.

We report a case of esotropia with high hyperopia in a 3-year-old female child. She was initially treated with hyperopic correction and noted to have residual esotropia, which was diagnosed as partial accommodative esotropia. Later when she presented with headache, she was diagnosed to have an intracranial tumour. To our surprise, after neurosurgical excision of tumour, her non-accommodative component of the esotropia resolved over 1 year implying that the intracranial lesion was an additional causative factor for this acute onset Accommodative esotropia. The child attained Orthophoria with the same hyperopic correction.
