ABSTRACT

Objective: to validate the examination procedures established by the Clinical Practice Guideline suggested for the screening of visual disorders at pediatric ages in the primary health care.
Methods: a descriptive, prospective and cross-sectional study of a sample of 633 patients aged 3-5 years was conducted at Marfan teaching pediatric hospital from February 2014 to January 2015. Two primary health care pediatricians and a psychologist performed the screening set by the clinical practice guideline; one ophthalmologist supervised and controlled the application of screening in line with the set protocol whereas the other, aided by an optometrist, made the selected tests as truth criteria. The study of the predictive capacity of the exam procedures in the suggested clinical practice guideline was based on four variables, i.e. visual acuity, stereopsis, eye alignment and fundus reflex examination. Data processing used Statistic software and Epidat 4.
Results: the overall values for sensitivity was 88.15 %, specificity 9.21 %, positive and negative predictable values reached 79.07 % and 98.57 %, respectively. The agreement force was very good, with K= 0.813.
Conclusions: the results confirm that the suggested Clinical Practice Guideline should be recommended as a valid tool to detect visual disorders at pediatric ages under the present conditions of the Cuban society.
