Insights
Children with recurrent strabismus experience significant visuomotor deficits, impacting learning and emotional well-being. These findings highlight the need for comprehensive assessments beyond visual acuity.
Area of Science:
- Ophthalmology
- Developmental Psychology
- Pediatrics
Context:
- Recurrent strabismus affects children's visual development.
- Assessing visuomotor skills, intelligence, and emotional state is crucial.
Purpose:
- To investigate visuomotor alterations, intelligence, and depression in children with recurrent strabismus.
- To correlate these findings with strabismus recurrence and severity.
Summary:
- Nine children with recurrent strabismus (mean age 6.8 years) were evaluated.
- Visuomotor tests revealed fine hand movement defects (Bender Test).
- Subnormal global intelligence (IQ 88.1) and executive function deficits were noted, alongside socialization difficulties and depressive signs.
Impact:
- Recurrent strabismus is associated with significant visuomotor impairments, stereovision loss, and cognitive/emotional challenges.
- Findings underscore the multifaceted impact of strabismus on a child's development.
- Highlights the importance of early and comprehensive intervention strategies.
Background:
We undertook this study to demonstrate the visuomotor alterations, intelligence level and depression changes in children with recurrent strabismus.
Methods:
Children with recurrent strabismus were studied with the Human Figure Test, Lauretta Bender Visuomotor Test, Intelligence Level of Weschler, WISC-R, and WPPSI. Complete exploration of strabismus was made.
Results:
We included nine children aged 6.8 years (SD 2). Overfunction of oblique muscles and dissociated strabismus were related to recurrence of strabismus. Stereovision was present in five cases previous to recurrence (rate: 170 sec of arc), and three lost this with recurrence of strabismus. Psychological test determined difficulties in socialization and signs of aggression, including data on depression and "dullness." Bender Test showed relevant defects in fine hand movement, level: 5.4 (SD 1.7). Santucci evaluation for Bender was 3.83 (SD 2.1). Correlation coefficient between values was significant for Santucci evaluation and stereovision (0.89). Global Intelligence Coefficient was 88.1 (SD 12), which was subnormal and poorer in executive function (84).
Conclusions:
We have demonstrated relevant alterations in visuomotor abilities in patients with strabismus, especially related to stereovision deficiency, effect on learning, intelligence and depression.
