Their subtypes are presented in Table 1. This has also contributed to the fact that over half the surgeries needed interventions in more than two extraocular muscles.

The global medical literature found frequencies ranging from 0.

Incidence and types of childhood esotropia: This number is lower than the one seen in the literaturewhich might be due to good results obtained by the first surgery, to a difficulty faced by patients in following up on their treatments due to socioeconomic issues, or to lower standards regarding esthetic results among the population under study Results of early alignment of congenital esotropia.

The prevalence of esotropia decreased with age, whereas that of exotropia increased.

Most surgical cases showed associated deviations, which renders programming and performing the parxliticos more complex. Acquired oculomotor, trochlear, and abducent cranial nerve palsies in pediatric patients.

Common forms of childhood esotropia. It has been found that children with strabismus are viewed negatively, and that surgery could lead to psychosocial benefits, even when there is no hope of improving visual function. New studies will be necessary in order to clarify this finding.

Psychosocial aspects of strabismus study. National Estrabissmos Institute; The involvement of oblique and vertical rectus muscles, the displacement of the rectus muscle, and the number of re-surgeries were also considered. Patients submitted to surgical procedures to correct strabismus including estranismos with application of botulinum toxin were included in the study, regardless of age or sex.

Retrospective cross-sectional review of medical records of patients who underwent strabismus surgery performed by the same surgeon from to Discussion It is difficult to compare the findings of the present study to other research, due to the methodological variability across the studies, to the fact that few parxliticos investigated surgical strabismus alone, 13, 14and to the lack of standardization in esttabismos classification of strabismus.

A possible explanation for this difference may be the fact that surgery is not recommended for several cases of intermittent XT, which are, however, still accounted for in population-based studies.

Although infantile ET is classically indicated as the most common type of esotropia among children, in recent studies this high prevalence has not been paralificos. The type of surgery was determined by the number of muscles operated on up to two, or more than twothe involvement of oblique and vertical rectus muscles, and muscle displacement.

Likewise, we observed that there was an increased demand for surgeries involving oblique muscles, vertical rectus muscles and displacement techniques. Prevalence and outcomes of childhood visual disorders.

Every surgical procedure performed in that period was evaluated and recorded as a case for the study. Additionally, most cases of accommodative ET may be corrected with plus lenses 11, 19 and do not need surgery, therefore not being widely represented among the subjects of this study 11,19 Regarding XT subtypes, we found trends similar to those found in other studies.

Long-term motor and sensory outcomes after early surgery for infantile esotropia. Treatment for strabismus may be either clinical, optical, or involving an association of techniques, and its purpose is to preserve and ensure adequate visual development, recover binocular vision, and establish ocular parallelism.

Revista Brasileira de Oftalmologia. Refractive Error Study in Children: Constant exotropia was the most frequent subtype of exotropia It is difficult to compare the findings of the present study to other research, due to the methodological variability across the studies, to the fact that few studies investigated surgical strabismus alone, 13, 14and to the lack of standardization in the classification of strabismus.

Epidemiology of surgical strabismus in Saudi Arabia. Among XT patients, vertical deviations Furthermore, most of the research is either population-based, or limited to a specific age bracket 13, This may either reflect a difficulty in gaining quick access to healthcare services, or a lack of qualified professionals and resources to perform an earlier surgery; further research is needed for a better understanding of this issue.

The prevalence of strabismus and amblyopia in Japanese elementary school children.

The type of surgery was determined paraliticoe the number of muscles operated on intervention in up to two muscles, or intervention in more than two muscles.

Original Articles Revista vol. This observation may demonstrate the importance of the surgeon being prepared to perform different techniques in several extraocular muscles. Strabismus was classified into three main types esotropia, exotropia, and pure vertical deviationand their subtypes.

A descriptive statistical analysis was conducted through the use of frequency distribution tables for each variable studied. Re-surgeries accounted for An association between different types of deviation was found in In addition, the study found a high rate of sensorial XT Strabismus was classified into three main types:
