ABSTRACT
PURPOSE: To compare the obliquity of the palpebral fissures of three different racial populations. METHODS: Prospective observational study. Frontal views of the palpebral fissures of three different groups of subjects (Brazilian whites, Brazilian Japanese, and Brazilian Indians from the Upper Rio Negro Basin of the Amazonas State) were acquired with a photographic camera and transferred to a Macintosh computer. Using the National Institutes of Health Image software (NIH Image), the angle formed by the inner and the outer canthi was measured for all images. RESULTS: The mean fissure angle of the Japanese (9.39 degrees) was not statistically different from the mean angle of the Indians (9.64 degrees). On the other hand, both were significantly greater than the mean angle of the whites (4.60 degrees). CONCLUSIONS: Marked fissure obliquity is found more frequently among Asians than among whites.

Upper eyelid cicatricial entropion is commonly encountered as a sequela of inflammatory conditions. The surgical correction of this defect is often difficult and frequently unsuccessful. We have used the Barbera-Carre technique with good results in 20 patients with cicatricial entropion due to trachoma. We take this opportunity to present the surgical technique and our results.
