Parents answered a questionnaire about the use of screens, ocular symptoms and family history of the child. Significance levels were defines as begin p≤0,05.
Results:
The results have shown that four hundred fifty-nine children were screened. Two hundred nineteen are female (47,7%) and two hundred fourty (52,3%), male. From all screened patients, one hundred were refered to specialized oftalmic evaluation. After trial completing, has been attained a prevalence value of 10,7% for myopia, 17,6% of hyperopia and 0,9% of strabismus. Strong correlation between parents and children has been undiscovered (p<0,05). From listed oftalmic complaints, headache (30,4%) and frown (10%) where most prevalent.
Conclusion:
It has been attained that the prevalence of visual acuity is 21,8%. The relation between visual acuity alteration and familiar history has been shown to be significant related. On the other side, the average time in front of television has been shown the only habit that has correlation with visual acuity reduction (p=0,028). Vision complaints, although very frequent, doesn't translate into increased probability of visual acuity alteration.
