PURPOSE: To quantify the potential cornea donor from the different units of Clinical Hospital of the UFPR. METHODS: 369 records of patients who died from april until july of 2005 in the HC-UFPR were analyzed. The medical records of each patient had been evaluated: the clinical evolution, CID-10 and hospital unit of the death. To be considered potential donor (PD) it was used as exclusion criteria the topics cited in the Manual of Transplants (2ª edition-2004) of the State Secretariat […]

PURPOSE: To analyze causes of discarded donor corneas which were collected and preserved by São Paulo Hospital Eye Bank in a period of two years. METHODS: Retrospective study based in the investigation of donor’s medical records, for clinical and ocular factors, age, death cause, serology results, body conditions, slit lamp corneal examination and endothelial cells counting. RESULTS: 1,116 corneas were donated and included in the study, 518 (46.41%) were discarded before preservation, 168 (15.05%) were not transplanted for optical purpose, […]

Objective: Analyze and identify critically the profile of patients with aphakic/pseudophakic bullous keratopathy attended at a public hospital. Methods: Retrospective analysis of 35 eyes of 35 patients with diagnosis of bullous keratopathy, which has been followed in the department of cornea and external diseases of Hospital da Piedade. The one whose pre and per operative data we did not find were excluded. This selection of patients was done from January to June of 2007. Results: As main results we found […]

Corneal transplant rejection is an immunological cellular process that attacks the donor cornea and may cause its failure. It is the most common cause of corneal transplant failure.The most common factors for rejection are corneal neovascularization, previous graft failure, anterior synechiae, large or descentered graft, intraocular inflammation and previous anterior segment surgeries. It commonly presents with hyperemia, ocular pain, corneal edema, and anterior chamber inflammation. Corneal graft rejection can be classified as epithelial rejection, subepithelial rejection, stromal rejection, endothelial rejection, […]

PURPOSE: To analyse the corneal astigmatism after transplantation as well as to demonstrate how post-surgical handling of sutures affects the refractive and visual outcome in patients submitted to cornea transplantation by keratoconus with three to six years of follow-up. METHODS: Non-controlled longitudinal observational secondary clinical study. Fifty records of patients submitted to penetrating keratoplasty between 2000 and 2002 have been reviewed, including 50 eyes of 50 patients operated under the same surgical technique by the same surgeon. Follow-up time ranging […]

PURPOSE: To assess the efficacy of topical cyclosporine .05% for preventing endothelial loss in cornea transplant. METHODS: Retrospective study of 18 eyes submitted to penetrating transplant due to keratoconus, operation carried out by the same surgeon. Patients with specular microscopy with lower than or equal to 1200 cells/mm2 belonged to the control group. The inclusion criterion was the occurrence of specular microscopy in the postoperative period over the 6- month, 1- year, and 2- year periods and the exclusion criterion […]
