We report the case of a 7-year-old girl who presented with sudden diplopia and blurred vision. She had a constant, comitant, alternating esotropia. Ocular motility and pupillary reactions were normal. She was diagnosed to have spasm of the near reflex presenting as acute onset of esotropia. Her mother appeared very nervous and her attitude toward her daughter was very strict. We presumed that the etiology was functional. We instructed her mother to treat the daughter kindly. One month after prescribing glasses, her best corrected visual acuity was 1.2 in each eye. She was orthophoric at distance and near, and her diplopia was completely resolved. Spasm of the near reflex needs to be considered in the differential diagnosis of acute acquired comitant esotropia.
