Abstract

Purpose: To investigate changes in strabismus angles in children and young adult patients with recent onset of constant acquired comitant esotropia (ACE) following instructions on hand-held digital devices (DD).

Study design: Prospective multicenter non-randomized interventional study.

Methods: This study included subjects aged 5-35 years who developed ACE within 1 year. Subjects were divided into two groups: (i) subjects who used DD for an average of ≥120 minutes/day for junior high-school students and older and ≥60 minutes/day for primary-school students and younger (DD+); and (ii) subjects who used DD for less than that (DD-) based on the questionnaire at the study's start. During the initial visit, glasses were prescribed when necessary; verbal instructions on DD use including time reduction and viewing-distance elongation were provided. For each group, strabismus angles at the initial visit and at 3 months were compared. Cure was defined as esophoria within 8 prism diopters without symptoms.

Results: In total, 181 cases were investigated. At baseline, strabismus angles in DD+ and DD- groups were 23±14 PD and 25±15 PD at near and 25±13 PD and 27±14 PD at distance, respectively. At 3 months, they were 22±16 PD and 25±15 PD at near and 23±14 PD and 27±13 PD at distance, respectively. Only in the DD+ group, reduction in strabismus angle was observed, but this was not clinically significant. Ten and 1 subjects in DD+ and DD- groups were cured.

Conclusion: Although changes in strabismus angles were not large enough, DD use instructions were beneficial for some ACE subjects.

期刊介绍： The Japanese Journal of Ophthalmology (JJO) was inaugurated in 1957 as a quarterly journal published in English by the Ophthalmology Department of the University of Tokyo, with the aim of disseminating the achievements of Japanese ophthalmologists worldwide. JJO remains the only Japanese ophthalmology journal published in English. In 1997, the Japanese Ophthalmological Society assumed the responsibility for publishing the Japanese Journal of Ophthalmology as its official English-language publication. Currently the journal is published bimonthly and accepts papers from authors worldwide. JJO has become an international interdisciplinary forum for the publication of basic science and clinical research papers.
