| Summary: | Com o objetivo de avaliar a hipótese de redução da sensibilidade do hemicampo nasal do campo visual, o que aumentaria a assimetria temporal-nasal dos hemicampos, nos pacientes com estrabismo convergente de aparecimento precoce (antes de dois anos de idade) em comparação aos normais, foram estudados os dois olhos de 66 pacientes, 33 estrábicos e 33 normais, com idade que variou de 7 a 30 anos, com o método da perimetria estática, utilizando-se o programa SITA Standard, do perímetro Humphrey HFA-II Série 700.

With the objective of analysing the hypothesis that a reduction in sensitivity of the nasal hemifield, that in turn would lead to an increase in the nasotemporal asymmetry of the visual field, in patients with early onset convergent strabismus - before 2 years of age - if compared to normal patients, both eyes of 66 patients - 33 esotropes and 33 normal - were studied. Patient's age varied from 7 - 30 years. The method of examination was that of Static Perimetry utilizing the Sita Standard program, of the Humphrey perimeter HFA II 700 Series. The results depicted a clear accentuation of the nasotemporal asymmetry in esotropes if compared to normal patients. This asymmetry was due to the evident decrease of sensitivity in the most peripheral of the chosen points of study. The quantitative sum of values of sensitivity of these points exhibited an average reduction of -15,71% in relation to the normal patients. For both groups, normal and esotropes, there was no difference in values of sensitivity between the to eyes.
