BACKGROUND Solitary fibrous tumor (SFT) is a rare, benign, and very uncommon lesion in the orbit. Because of its complex and variable clinical and histological appearance the SFT is often misdiagnosed. CASES Two new cases of orbital SFT are reported, one in a man and the other in a woman, both unilateral and in the superomedial orbit. OBSERVATIONS(More)
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)
BACKGROUND This paper reports population-based data on the prevalence and causes of visual impairment among children and adults in Botucatu, Brazil. METHODS A population-based cross-sectional study was conducted involving a random start point and then systematic sampling of an urban Brazilian population in the city of Botucatu. There were approximately(More)
OBJECTIVE To present the clinical features and management in a series of patients with orbital and adnexal sarcoidosis. METHODS This multicenter retrospective study included patients with biopsy-proven noncaseating granuloma involving the orbit or adnexa and evidence of systemic sarcoidosis. Clinical records were reviewed for initial examination findings,(More)
PURPOSE To determine the prevalence and demographic associations of refractive error in Botucatu, Brazil. METHODS A population-based, cross-sectional prevalence study was conducted, which involved random, household cluster sampling of an urban Brazilian population in Botucatu. There were 3000 individuals aged 1 to 91 years (mean 38.3) who were eligible to(More)
PURPOSE Because the influence of papillomavirus (HPV) in pterygium pathogenesis is controversial, the aim of this study was to identify whether it is present in the pterygia lesions in our region. METHODS Thirty-six patients with unilateral primary pterygia were submitted to excision of pterygia and a sample of normal conjunctiva. Tissues were submitted(More)
A 56-year-old healthy man underwent left medial rectus recession and lateral rectus resection for esotropia. The next day he developed severe left periocular pain with decreased vision, an afferent pupillary defect, periorbital edema, limited ocular motility, and proptosis. Computed tomography showed fat stranding and less than 90 degrees of posterior globe(More)
PURPOSE Gelatinous polyethylene (GP) has been used as an orbital implant to evaluate volume maintenance and tissue reaction in the anophthalmic socket in a rabbit model. METHODS Twenty-eight Norfolk white rabbits underwent unilateral evisceration with placement of 2 ml GP (GP group - 16 animals) or 2 ml 0.9% sodium chloride solution (Control group - 12(More)
UNLABELLED Leishmaniasis infection may involve destruction of nasal tissues resulting in lacrimal drainage system alteration. 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 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)
