Patients with strabismus performed worse than controls in a surgical peg transfer task, highlighting potential impacts on hand-eye coordination. Further research is needed to fully understand strabismus

Area of Science:

Ophthalmology
Surgical Education
Human Performance

Background:

Strabismus, a common eye misalignment, can affect binocular vision and depth perception.
The impact of strabismus on fine motor skills and surgical performance is not well-established.
Assessing hand-eye coordination in individuals with strabismus is crucial for understanding potential challenges in surgical training.

Purpose of the Study:

To compare the surgical training performance of patients with strabismus versus age-matched controls.
To evaluate hand-eye coordination using a validated surgical training module.

Main Methods:

A prospective experimental study involved 14 adult patients with strabismus (absent stereopsis) and 14 age-matched controls (normal stereopsis).
Participants completed 10 timed peg transfer trials on a validated surgical training device after standardized instruction.

A Structured Rehabilitation Protocol for Improved Multifunctional Prosthetic Control: A Case Study

Published on: November 6, 2015

Performance was assessed by comparing the mean of the best 5 scores between the two groups using the Wilcoxon rank-sum test.

Main Results:

The mean age of strabismic patients was 34.8 years and controls was 37.8 years.
Strabismic patients had a mean score of 82.5 +/- 26.7 seconds, while controls scored 64.7 +/- 23.9 seconds.
Controls demonstrated significantly better performance (p = 0.022) in the surgical training task.

Conclusions:

Patients with strabismus exhibited poorer performance in a hand-eye coordination model compared to controls.
Significant overlap in performance existed between groups, with some strabismic patients outperforming the control group mean.
Further investigation is warranted to fully elucidate the specific effects of strabismus on surgical skill acquisition and performance.
