Exclusion criteria were those with palpebral position alterations, prior palpebral surgery, and crossbreeding. Images were obtained with a digital camera, 30 cm from the frontal plane at pupil height, with the individual in a primary position and the eye trained on the camera lens. Images were transferred to computer and processed by the Scion Image program. Measurements were made of distance between medial canthi, distance between pupils (IPD), superior eyelid crease position, distance between the superior lid margin and corneal reflexes (MRD), horizontal width, height, area, and obliquity of the palpebral fissure. Data were analyzed using analysis of variance for a three factor model and respective multiple comparison tests.Results: Japanese residents and Nikkeis living in Brazil have similar measurements. Statistical differences were found for some age groups concerning distance between pupils, horizontal, and vertical fissures, palpebral fissure area, and obliquity with native Japanese presenting discretely higher measurements than Nikkeis.Conclusion: Environmental factors do not affect palpebral dimensions of Nikkeis living in Brazil.Keywords: eyelid dimensions, Japanese, Nikkeis, digital imag

Hyperbaric oxygen in the management of wound tissue necrosis after external dacrocystorhinostomy

Hyperbaric oxygen is an adjunctive treatment for promoting wound healing and reducing infection. We present an unusual case of wound tissue necrosis occurring after external dacryocystorhinostomy (ExtDCR) that was subsequently treated with hyperbaric oxygen (HBO) and advancement flaps with good outcome. HBO improves vascularization of ischemic tissues after ExtDCR for greater success after reconstructive surgery

Comments: the positional eyelids disorders and the benign lesions were the manly pathologies observed The knowledge of the oculopalpebral alterations frequence is important to prevention and in order to teach new professionals who will act in this Ophthalmology area

Cinedacryocystography in the diagnosis of lacrimal obstruction in children

Purpose: To analyze the cinedacryocystography in children with congenital nasolacrimal obstruction suspicion. Methods: The cinedacryocystographic examination was done in 143 children (58% of girls and 42% of boys) younger than 5 years old, suspected of congenital nasolacrimal obstruction. The exams were done under general anesthesia and the children were probed immediately when obstruction was detected. Results: Epiphora, discharge or both were the most common complaints. Nevertheless 11% children had undergone unsuccessfully probing once, no one had any radiologic evaluation previously. The cinedacryocystographic exam showed nasolacrimal duct obstruction in 65,73%. Permeable lacrimal vies were presented in 34,3% of the children with epiphora. The obstruction was mainly at the Arlt's sinus. Using the cinedacryocystography, it was possible to observe the lacrimal sac enlargement and alterations in the contiguous structures such as hypertrophic turbinates (91,1%), sinusitis (44,6%) and septum deviation (24,1%). Conclusion: Cinedacryocystographic evaluation provides important information about lacrimal system obstruction in children, therefore, it is useful in all children with suspected congenital lacrimal obstruction
