Abstract:
PURPOSE:To evaluate trends in the acquisition, storage, and utilization of donated corneal tissue in New Zealand, 2000 to 2009. METHODS:The New Zealand National Eye Bank records were analyzed for the decade January 2000 to December 2009. Variables analyzed included donor demographics (age, sex, and ethnicity), donor source, donor cause of death, death-to-preservation interval (DPI), corneal storage time, tissue contamination, endothelial assessment, cornea suitability for transplantation, and corneal tissue utilization. RESULTS:A total of 1268 eye donors were identified during the 10-year period. Overall, 36% (n = 457) were female and 64% male (n = 813). Median donor age was 67 years, and 23% of donors were younger than 50 years (range, 5-90 years). There was a decrease in donor age over the decade (P = 0.006). The median DPI was 18.5 hours. No relationship was identified between cornea suitability for transplantation and DPI (P = 0.28) or donor gender (P = 0.54). There was a low microbial contamination rate (1%). Human immunodeficiency virus, hepatitis B, or hepatitis C serology was positive in 48 donors (4%). Overall, 90% of corneas were suitable for transplantation with a high utilization rate (88%). A novel association was identified between male sex and lower corneal endothelial cell density (P = 0.03). CONCLUSIONS:This New Zealand National Eye Bank analysis identified trends in the acquisition, storage, and utilization of donated corneal tissue throughout New Zealand over the past decade and provides valuable additional information to the international eye bank data.
