ABSTRACT

Introduction: the involuntary eye movements in childhood may compromise the child´s visual acuity; hence it is important to properly manage them.
Objectives: to describe the type of nystagmus and the prescribed treatment for each patient suffering the infantile nystagmus syndrome.
Methods: observational, descriptive and cross-sectional study conducted in 60 patients with diagnosis of infantile nystagmus syndrome. Age, types of nystagmus, associated refractive defects and prescribed treatments in each case were analyzed and processed with statistical analysis software SPSS for Windows, version 2.1. Mean and median; and standard deviation and interquartile range were used as central tendency and as dispersion measures, respectively.
Results: the average age of the studied patients was 5,8 years. Men predominated (56,7 % vs. 43,3 %). The sensorial nystagmus was the most frequent (80 %) and the median was 4 years and 6 months. The most common cause in this nystagmus type was papillary hypoplasia (20,8 %) in both sexes. The hypermetropic astigmatism was the most found refractive defect in these patients. The drug treatment was the most used (65 %), particularly 2 % dorzolamide eyedrop (94,9 %). The surgical treatment was used in 20 % of the patients and the most used technique was recession of the 4 horizontal rectus muscle.
Conclusions: sensorial nystagmus is the most frequent and they are fundamentally managed with drug treatment.
