ABSTRACT Objective: To characterize the morphological aspects related to the integrity of the corneas. Methods: A biomicroscopic analysis of the corneas collected from January 2019 to January 2021, by the Human Eye Tissue Bank of Hospital João XXIII, in order to identify the main changes that led to their discarding, based on the medical records analyzed. Results: Almost all variables coincided with what the literature indicates; however, stromal infiltration manifested differently. Conclusion: The main discarding factors were epithelial exposure, epithelial […]

The selection of these corneas is based on three rules: innocuousness, transparency and vitality. Each one of these concepts is considered […]

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, […]
