He had a history of 6 hours of smartphone usage per day. Orthoptic examination showed esotropia of 35 prism diopters (PD) at distance and 30 PD at near. Neuroimaging was normal. The patient underwent bilateral medial recession of 5.5 mm. After 8 months of follow-up, the patient was orthophoric, and full stereopsis was restored.Conclusion: Our case demonstrated the insidious onset of myopic comitant esotropia in a teenager in whom excessive smartphone use could have accelerated the onset of the disease. Augmented bilateral medial rectus recession yielded a good outcome.Keywords: myopia, esotropia, comitant esotropia, strabismus, acquired esotropia
