PURPOSE To evaluate normal Tenon capsule fibroblasts and from pterygia in culture when exposed to cyclosporin 0.05%. METHODS A prospective, randomized study was done, involving 20 patients with primary pterygium. Samples of normal and pterygium Tenon's capsule from the same individual were collected, cultured and exposed to cyclosporin 0.05%. RESULTS(More)
PURPOSE To evaluate the fibroblast proliferation activity of normal Tenon's capsule from primary and recurrent patients with pterygium. METHODS A randomized prospective study was performed with 41 normal Tenon's capsule fragments from 21 primary and 20 recurrent patients with pterygium. The sample was collected from the inferior cul-de-sac. Proliferation(More)
PURPOSE To evaluate the possibility of epiphora relief in congenital nasolacrimal obstruction according to the age of the beginning of epiphora complaint and treatment effectiveness. METHODS Forty children with congenital nasolacrimal obstruction underwent treatment between 1997 and 1999 and were evaluated according to: age of start of epiphora, the(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)
Age-related morphological, ultrastructural and morphometric changes in the capillaries of the superficial and deep plexuses of the rat retina were studied in animals aged from 3 to 15 months. Our results suggest that age-related morphological alterations start occurring in the retina of rats at about 12 months of age. Increased glycogen deposits,(More)
PURPOSE To evaluate a bone morphogenetic protein (BMP) implant with and without platelet-rich plasma (PRP), which is supposed to accelerate fracture consolidation in the orbit fracture treatment. METHODS Thirty-six white rabbits were subjected to orbital fracture and treated in three groups: BMP implant fracture repair (G1), BMP plus PRP implant fracture(More)
PURPOSE To assess the efficacy and safety of porous and nonporous implants for management of the anophthalmic socket. METHODS Case series meta-analysis was conducted with no language restriction, including studies from: PUBMED, EMBASE and LILACS. Study eligibility criteria were case series design with more than 20 cases reported, use of porous and/or(More)
We report three rare cases of ethmoid osteoma extending to the medial quadrant of the orbit that had singular particularities, such as occurring in women, at an unusual age group, and complaint of epiphora. The radiographic images were typical of this condition. Patients were submitted to surgery with complete resolution of the disease.
