Eyelid colobomas are congenital defects caused by failure of fusion of the mesodermal lid folds. The timing and approach to surgical repair depend on the severity of the defect and exposure keratopathy. Tarsomarginal grafts have been well described in eyelid reconstructions following tumor excision. Descriptions of lid coloboma repair using this approach(More)
The study compared the host response to a human and a porcine acellular dermal tissue implanted in the subcutaneous space of a rat model. The human and porcine acellular grafts were surgically implanted in the subcutaneous tissue of rats (5 rats/group) and the materials were evaluated at 7, 15, 30, 60 and 180 postoperative days (PO). The histological immune(More)

PURPOSE To evaluate the frequency of lacrimal excretory system sequelae in patients treated for leishmaniasis. METHODS Forty-five leishmaniasis-treated patients (90 nasolacrimal ducts) were submitted to lacrimal excretory system(More)
PURPOSE Spontaneous eye blink activity in the primary eye position and its relationship to age and gender were assessed using digital image processing techniques to quantify blink opening and closing time. METHODS One hundred-and-eighty healthy volunteers (90 males and 90 females), divided into the age groups 0-3, 4-12, 13-20, 21-40, 41-60 and > or = 60(More)
PURPOSE To assess matrix metalloproteinase (MMP)-9 expression in pterygium lesion. METHODS A prospective randomized clinical trial was done to evaluate the expression of matrix metalloproteinase in normal and in primary or recurrent pterygia in Tenon's capsule by immunohistochemical analysis and a computerized image analysis system. The data were(More)
