Two Cases of Acute Acquired Comitant Esotropia

Acute acquired comitant esotropia has been used to describe a dramatic onset of a relatively large angle of esotropia with diplopia and minimal refractive errors. The authors experienced two cases of acute acquired comitant esotropia in patients with the age of 28 and 40 years. Sudden diplopia and esodeviation developed in both patients. All ophthalmologic and neurologic examinations including brain MRI showed negative results. Amount of deviation remained constant. We performed recession of both medial rectus muscles. Four weeks after surgery, both patients showed orthotropia without any complaints of diplopia.
