Varied aetiology of acute acquired comitant esotropia: A case series

Abstract

This is an observational case series of five cases of acute acquired comitant esotropia (AACE) with diplopia, aged between 5 and 12 years. The duration of presenting complaints ranged from 4 days to 2 months. A detailed ophthalmic evaluation and neuroimaging were done on all patients. Three patients were found to have intracranial pathology. Two patients had pontine glioma and one patient had benign intracranial hypertension. One patient was diagnosed as accommodative spasm and one patient was diagnosed as having Type 2 AACE.We would like to conclude that AACE can be of a varied aetiology ranging from convergence spasm to those harboring serious intracranial diseases. We reiterate that AACE has a small but significant association with intracranial disorders. Neuroimaging is a definite need in cases which cannot be proved to be either Type 1 or 2.
