title: Donor eyes. A comparison of characteristics and outcomes for Eye Bank and local tissue.
abstract: The Corneal Recipient Registry was begun in 1985 to collect information on all recipients of corneal grafts in the province of Ontario, Canada, and on the donors providing tissue. While most of the tissue is handled by the Eye Bank of Canada (Ontario Division), ophthalmologists in centers away from the Eye Bank often use local tissue when it is available. Comparison of the donor characteristics of local tissue with that obtained through the Eye Bank revealed that local donors were 9-10 years younger (p less than 0.01), their times to enucleation were an hour less (p less than 0.02), and they were much more likely to be the victims of trauma than the donors of Eye Bank eyes. Prognosis of the graft, assessed using life table methods, suggested that success of local eyes was 89% after 6 months, compared with 80% for Eye Bank eyes in the same period, but this was not a significant difference (p greater than 0.05). While the Eye Bank is a more common source of tissue, eyes obtained locally are more likely to represent the "ideal" tissue for many corneal surgeons.
