Characteristics of corneal donors in the Cascavel Eye Bank: impact of the anti-HBc test for hepatitis B

To describe the characteristics of human ocular tissue donors from the Cascavel Eye Bank in the State of Paraná (PR) and investigate the impact of hepatitis B serologic test positivity on discarded ocular tissues. Cross-sectional study of data collected between March 2006 and April 2007 at the Cascavel Eye Bank. Information such as age, gender, cause of death, time between death and enucleation, and serologic tests results was collected. Data were used to characterize the study population and stratified according to hepatitis B (anti-HBc) status. Mean age of donors was 54.2 ± 20.6 years and a greater proportion of men (64,7%) was observed. Mean time between death and enucleation was 3.8 ± 2.4 hours, cardiovascular diseases were the main cause of death (34.5%). Positivity of anti-HBc and HBsAg tests was 47.4% and 1.5%, respectively. Hepatitis B was the main reason for discarding corneas. Donors whose serologic tests were positive for anti-HBc had higher mean age compared to those with negative tests (p
