Analysis of independent risk factors for acute acquired comitant esotropia

Abstract

AIM: To explore the risk factors for acute acquired comitant esotropia (AACE). METHODS: A retrospective cohort study was conducted by analyzing 83 patients (case group) with AACE who underwent strabismus correction surgery from January 1, 2021 to June 30, 2022. Totally 73 outpatient volunteers were recruited during the same period as the normal control group. The case group’s binocular vision time, near and distance esotropia angle, and near stereo vision function were recorded, and the age, gender, refractive status, and best-corrected visual acuity (BCVA) of both groups were analyzed. Additionally, multiple logistic regression analysis was conducted using an eye usage condition questionnaire to determine the independent risk factors for AACE. RESULTS: In the case group, 61 patients (73.49%) had myopia, with a mean equivalent spherical power (SE) of -3.35±3.31 D (range: +2.75 to -10.62 D) of the right eye and -2.87±3.35 D (range: +2.75 to -11.12 D) of the left eye. The average duration of diplopia in the case group was 29.83±35.72mo, of which 80 patients (96.39%) were primarily with distance diplopia. The near and distance esotropia angle after wearing glasses were 52.36±20.95 prism degree (PD) and 56.71±19.54 PD, respectively, and there was no statistically significant difference between the two (t=1.38, P=0.169). The incidence of improper glasses wearing and unhealthy eye habits in the case group was significantly higher than those in the control group (P<0.05). Close-up work without glasses [β=2.30, odds ratio (OR)=10, 95% confidence interval (CI) 2.35-42.51, P=0.002] and near work in supine position (β=1.80, OR=6.02, 95%CI 3.29-11.02, P<0.001) were independent risk factors for AACE. CONCLUSION: Patients with AACE mainly present with distance diplopia, and there is a high degree of variation in myopia. Near work without wearing glasses and in supine position are independent risk factors for AACE.

Acute acquired comitant esotropia induced by excessive digital device usage – literature review

“…Cai i wsp. przeprowadzili też inne retrospektywne badanie kohortowe, w którym grupa badawcza liczyła 83 osoby [31]. Byli to pacjenci w przedziale wiekowym od 5 do 52 lat, leczeni w szpitalu w Kuangsi w Chinach, u których zdiagnozowano AACE i wykonano operację korekcji zeza.…”

“…Ponadto czas pracy w bliży wzrokowej w ciągu dnia w grupie badawczej (5,47 ± 2,41 h) był istotnie dłuższy niż w grupie kontrolnej (4,55 ± 1,35 h, p = 0,029). Wyniki powyższego badania sugerują związek pomiędzy korekcją wady refrakcji, nawykami wzrokowymi a występowaniem AACE [31].…”
