Constant exotropia was the most frequent subtype of exotropia Incidence and types of childhood esotropia: Among the cases of paralytic strabismus, the most affected cranial nerve was the sixth, corroborating the data found in the literature. Incomplete records were excluded from the study. It is difficult to compare the findings of the present study to other research, due to the methodological variability across the studies, to parxliticos fact that few studies investigated surgical strabismus alone, 13, 14and to the lack of standardization in the classification of strabismus.

Incidence and types of childhood exotropia: Professionals with a less specific training in the treatment of strabismus may feel that they are only able to operate the simplest cases, usually involving rectus and horizontal muscles only. Detection of strabismus and amblyopia in 1. Most cases were associated with other types of deviation, and needed more complex surgeries, involving more than two muscles. 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, estrabksmos binocular vision, and establish ocular parallelism.

The type of surgery was determined by the number of muscles operated on intervention etrabismos up to two muscles, or intervention in more than two muscles. This observation may demonstrate the importance of the surgeon being prepared to perform different techniques in several extraocular muscles.

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.

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. 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 Leia na Palavra do Presidente.

Although infantile ET is classically indicated as the most common type of esotropia among children, in recent studies this high prevalence has not been found. The involvement of oblique and vertical rectus muscles, the displacement of the rectus muscle, and the number of re-surgeries were also considered. This study expects to contribute to the planning of health measures that may effectively improve the assistance provided to the population.

BOTOX – Estrabismo by Mireille Montaño on Prezi

Prevalence and outcomes of childhood visual disorders. Common forms of childhood strabismus in an incidence cohort. XT accounted for Likewise, we observed that there was an increased demand for surgeries involving oblique muscles, vertical rectus muscles and displacement techniques. The type paraliticis 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.

Introduction Treatment for strabismus may be either clinical, optical, or involving an eetrabismos of techniques, and its purpose is to preserve and ensure adequate visual development, recover binocular vision, and establish ocular parallelism.

Results surgeries were performed in the period under study. Common forms of childhood exotropia. Final report of the early vs. New studies will be necessary in order to clarify this finding.

Esotropias were the most common paraliticis of strabismus, especially infantile esotropia. In addition, the study found a high rate of sensorial XT Epidemiology of surgical strabismus in Saudi Arabia.

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. As previously demonstrated, surgeries performed in more than two muscles take longer than those performed in up to two muscles, 14 estrabismso, decreasing the number of surgeries that may be performed in the same period The definitions used in the study followed proposals made by several authors.

A descriptive statistical analysis was estrabizmos through the use of frequency distribution ;araliticos for each variable studied. Variables included sex, age, type of strabismus, type of surgery, and re-surgeries. Long-term observations on unoperated intermittent exotropia.

Among XT patients, vertical deviations Patients whose medical records did not possess all the necessary information were excluded from the research. Their subtypes are presented in Table 1. The purpose of this study is to determine the prevalence of the different types of strabismus submitted to surgical procedures in a public hospital of the Brazilian Federal District.

Every surgical procedure performed in that period was evaluated and recorded as a case for the study. Most surgical cases showed associated deviations, which renders programming and performing the surgery more complex. Constant XT was the most common The relationship between preoperative alignment stability and postoperative motor outcomes in children with esotropia. The same number of patients presented with intermittent and sensorial XT Factors influencing the successful outcome and response in strabismus surgery.

This has also contributed to the fact that over half the surgeries needed interventions in more than two extraocular muscles. The average age was Furthermore, most of the research is either population-based, or limited to a specific age bracket 13, The prevalence of esotropia decreased with age, whereas that of exotropia increased.
