ABSTRACT
Objective: to determine the existence of stereopsis in children operated on from strabismus in "Ramón Pando Ferrer" Cuban Institute of Ophthalmology.
Methods: observational, descriptive and cross-sectional study from March to October, 2011. Fifty children were randomly selected to undergo a complete ophthalmologic
exam.
Results: females (60 %) and the 3 to 4 years-old age group (32 %) prevailed. In the study group, 84 % of the patients had visual acuity of 1.0, and just 10 had stereopsis. The patients younger than 2 years old represented the highest number with postsurgical stereopsis. Most of the children were diagnosed as congenital esotropia,
but just 5 children had stereopsis added to this type of strabismus. Another type of strabismus found was the intermittent exotropia.
Conclusions: in the strabismus surgery, reaching the ocular alignment and its stability as well as the vision co-ordination in both eyes, does not attain very encouraging sensory outcomes when a child is operated on at later age. An early surgical intervention is important to improve the functional visual results, mainly before 2 years of age.
