Purpose
To evaluate visual acuity, refractive error, and angle of deviation in patients with large-angle esotropia and to investigate age related differences in the magnitude of deviation.
Methods
In this retrospective study, medical records of 370 patients diagnosed with large-angle esotropia (horizontal deviation ≥ 50 prism diopters (Δ)) between 4 and 81 years were reviewed.
n = 370 patients
Results
79.72
± 16.9 Δ
in adults, the eyes turn inward more than in children
n = 370 patients
More results
The mean age of patients was 28.9 ± 17.77 years, and 61.4% were male.
The mean horizontal angle of deviation at distance was 72.2 ± 14.08Δ.
The mean corrected distance visual acuity was 0.54 ± 0.55 logMAR in the strabismic eye and 0.14 ± 0.22 logMAR in the nonstrabismic eye (p < 0.001).
More results
The mean spherical equivalent (SE) was not significantly different between the strabismic (-0.31 ± 3.77 diopter (D)) and non-strabismic eye (-0.29 ± 3.46 D) (p = 0.9).

Conclusion
Large-angle esotropia is associated with significant visual impairments, including strabismic amblyopia, as the predominant factor, emphasizing the need for early diagnosis and individualized and timely intervention to prevent the long-term visual deficits.
