RESUMO
Purpose: To examine the utilization patterns of cornea procured from diseased individuals ?75 years of age at an eye bank in western India. Methods: In this retrospective study, data from 1,217 eyes of 653 donors with age ?75 years were reviewed from October 2008 to December 2019. Donor age, lens status, endothelial cell count (ECD), utilization of the tissue for transplantation or non?clinical purposes (e.g., research, training/discarded), and causes of non?utilization were noted. Results: The mean age of the donors was 80.9 ± 4.6 years and the tissue utilization rate was 36.5% (445 out of 1,217 eyes). The eyes used for keratoplasty procedures had a lower donor age (79.6 ± 5.7 vs. 81.5 ± 5.1; P < 0.001), a higher endothelial cell count (2493 ± 531 vs. 2034 ± 581; P < 0.001), and were more often phakic (61% vs. 36.6%) compared to the unused group. A multivariable logistic regression analysis showed that the likelihood of tissue utilization for keratoplasty was 13% higher with every 100?cell increment in donor ECD (odds ratio [OR] = 1.13, 95% CI = 1.10–1.16, P < 0.001) and 33% lower with having a pseudophakic status in the donor eye (OR = 0.67, 95% CI = 0.52–0.87, P = 0.03). Age was not a significant determinant of tissue utilization when used in the same multivariable model. Conclusion: More than one?third of the eyes (36.5%) can be utilized even when the donors are above 75 years of age. Eyes that were more likely to be utilized for keratoplasty were phakic and had a significantly higher ECD; age was not a determinant in tissue utilization
RESUMO
Objective: To identify the causes for the discards of corneas in the ocular tissue bank from Rio Grande do Norte. Method: This was an exploratory descriptive study, with retrospective data and quantitative approach, conducted in the ocular tissue bank from Rio Grande do Norte. The information was collected by means of an instrument containing: number of collected, transplanted, and discarded corneas; causes for the discards. Results: Out of the 548 collected corneas, 78.1% were preserved and 21.9% discarded.The prevalent causes for the discards were: stromal infiltrate, positive serology, and expired validity. Conclusion: Health professionals should be prepared to decrease the loss of corneas for avoidable reasons...
Objetivo: Identificar as causas dos descartes de córneas no banco de tecidos oculares do Rio Grande do Norte. Método: estudo exploratório descritivo, com dados retrospectivos e de abordagem quantitativa,realizado no banco de tecidos oculares do Rio Grande do Norte. As informações foram coletadas por meio de instrumento contendo: número de córneas preservadas, transplantadas e descartadas; causas dos descartes. Resultados: das 548 córneas captadas, 78,1% foram preservadas e 21,9% descartadas. As causas prevalentes dos descartes foram: infiltrado estromal, sorologia positiva e validade inspirada. Conclusão: os profissionais da saúde devem diminuir a perda de córneas por motivos evitáveis...
Objetivo: Identificar las causas de los descartes de las córneas de un banco de tejidos oculares de RioGrande do Norte. Método: Estudio exploratorio descriptivo con los datos retrospectivos y enfoque cuantitativo llevado a cabo los tejidos oculares de stock de Rio Grande do Norte. La información se recogió mediante un instrumento que contiene: número de córneas trasplantadas conservadas y descartadas;causas de los descartes. Resultados: De 548 trasplantes de córnea, el 78,1% y el 21,9% fueron preservados descartado. Las causas más frecuentes de los descartes fueron: infiltrado estromal, serología positiva y la validez de inspiración. Conclusión: Los profesionales de salud deben reducir la pérdida de córneas por razones evitables...
