Results.
Seventy-eight patients (89%) had ocular abnormalities. Refractive errors were found in 53 patients (60%). Strabismus including exotropia (50%), esotropia (9%), and hypertropia (9.1%) was found in 52 patients (59%). Posterior segment abnormalities were found in 19 patients (22%), cornea and lens abnormalities in 8 patients (9%), and epiblepharon in 5 patients (6%). Among 57 patients whose visual acuity could be measured, best-corrected visual acuity of the better eye was ≤20/40 in 18 patients (32%) and ≤20/200 in 3 patients (5%). Objective vision-impairing ocular abnormalities and vertical strabismus were significantly associated with poor gross motor function before orthopedic surgery.
Conclusions.
Ocular abnormalities were present in the majority of CP patients and patients with poor gross motor function were more likely to be afflicted with vision-impairing ocular abnormalities. Ophthalmologic evaluation is deemed necessary in CP patients, especially in those with poor motor function.
