Two Cases of Acute Acquired Comitant Esotropia after Occlusion Therapy

PURPOSE: To describe the new type of acute comitant estropia with dual cause of fusional dysfunction due to occlusion and refractive-accommodative factors. METHODS: We experienced two case of acute, acquired comitant esotropia in the course of occlusion therapy. The patients had mild hyperopia and severe accommodative tendency. RESULTS: After strabismus surgery, the patients have orthophoria and stereopsis recovery. CONCLUSIONS: We believe that the patients with acute comitant esotropia and abrupt diplopia should undergo thorough ophthalmological, neurological evaluations. And, acute comitant esotropia might occur during the occlusion therapy for amblyopia.
