Avaliação de córneas doadoras em lâmpada de fenda e microscopia especular durante o período de armazenamento

Abstract: Corneal grafts from younger donors had significantly better evaluation than those of older donors. The mean time of the evaluation change was on the 5th day in 50% of the corneas, however, an expressive number of corneas suffered changes on the 6th, 7th and 8th day. Corneal graft preserved after 6 hours of death had a greater tendency to lower cell count and to decrease in evaluation grades.

“…This fact is relevant due to the high economic impact that this specific population represents to the economy of a nation, leading to a loss of immeasurable value to society (13) . The average age of donors was 37.3 years, being lower than that found in other studies (6,9,10,(14)(15)(16) . We believe that it reflects a trend of large urban centers where youngsters are progressively more related to the various types of deaths associated with external causes, from crime to car accidents.…”

“…Over the years, the quality of the tissue changes, as pointed out in the literature by Farias (23) and Pantaleão (16) . These authors show that only the tissue analysis makes it possible to rule out potential donors not only due to age (14,16,23,24) . Sometimes this small number of donors is justified by the specific type of the collection center of donor corneas (IML), and thus a bias of our sample may be demonstrated.…”

“…O banco de tecidos oculares (BTO) tem a função de captar, avaliar, preservar e distribuir córneas e outros tecidos oculares, sendo responsabilidade deste, assegurar que as córneas apresentem padrão satisfatório aos cirurgiões transplantadores (1) . Com o aumento do número de córneas doadas e armazenadas por períodos mais longos, a avaliação criteriosa torna-se procedimento indispensável e de grande responsabilidade dos bancos de tecidos oculares.…”

“…Com o aumento do número de córneas doadas e armazenadas por períodos mais longos, a avaliação criteriosa torna-se procedimento indispensável e de grande responsabilidade dos bancos de tecidos oculares. Com este enfoque, alguns dados sobre a córnea doadora como a idade do doador e causa do óbito, são pautas de dúvidas sobre a qualidade da córnea (1)(2) . Alguns trabalhos referem a idade da córnea doadora como não sendo fator determinante na qualidade da córnea (3)(4)(5) .…”
