Characteristics of horizontal saccades in children with intermittent exotropia.
Purpose: To analyze the peak velocity and gain of horizontal saccades in children diagnosed with intermittent exotropia (IXT) and to compare these measurements with those obtained from children without strabismus.
Methods: Participants included children ≤12 years of age with IXT and no history of strabismus surgery and children without strabismus. The peak velocity and gain of horizontal saccades recorded using an eye tracker were analyzed.
Results: A total of 48 children (including 38 with IXT) were included. In the IXT group, the angles of deviation at near were 30.3Δ ± 13.5Δ; at distance, 30.6Δ ± 10.5Δ. Stereopsis was ≤60 arcsec in 29 patients and 80-400 arcsec in 9 patients. In the IXT group, the peak velocity and gain of the adduction saccade tended to be greater than those of the abduction saccade, but not significantly. The no-strabismus group exhibited a similar trend, with a stronger tendency in the dominant eye, reaching statistical significance.
Conclusions: Both the children with IXT and children without strabismus showed a dominance of adduction in their saccades; however, this dominance was weaker in children with IXT.
期刊介绍：
Journal of AAPOS presents expert information on children''s eye diseases and on strabismus as it affects all age groups. Major articles by leading experts in the field cover clinical and investigative studies, treatments, case reports, surgical techniques, descriptions of instrumentation, current concept reviews, and new diagnostic techniques. The Journal is the official publication of the American Association for Pediatric Ophthalmology and Strabismus.
