Abstract: Objective To observe the clinical features of acute acquired distance esotropia (AADE). Design Retrospective case series. Participants 18 AADE patients. Methods The optometry, deviation and another related ophthalmic examination were reviewed in 18 AADE patients. Continually near-distance use of eyes for long time, and outdoor activities were questionnaired. Main Outcome Measures Age, near and distance esotropia deviation, diplopia, time of near-distance use of eyes and outdoor activities each day. Results In all 18 patients, 11 cases (61.11%) were males. All patients complained diplopia. 13 cases (72.22%) had distance diplopia only, 5 cases (27.78%) had both near and distance diplopia, but more severe in distance. 13 cases (72.22%) were computer aplication related occupation. Mean age was 26.89±5.20 years. Mean diplopia period was 14.94±21.09 month. Mean time of near-distance use was 13.28±3.52 h/d. Mean time of outdoor activities was 0.77±0.43 h/d. Mean sleeping time was 7.36±0.51 h/d. Mean corrected esotropia deviation of 33 cm distance was 7.06±10.98 prism diopters(PD). Mean corrected esotropia deviation of 6 meters distance was 12.83±11.73 PD. Mean equivalent spherical(ES) refraction of both eyes was -3.81±2.11 D. Conclusion AADE can occur in myopia young adults for long time near-distance eye use and rare outdoor activities, which characterized by diplopia when look far away.
