Résumé
Objetivo: Traçar o perfil das doações de córnea obtidas pelo Banco de Tecidos Oculares do Hospital Getúlio Vargas (BTOC-HGV), avaliar a qualidade do tecido captado e enumerar as indicações do transplante de córnea. Métodos: Estudo retrospectivo de ficha de doadores cadastrados no BTOC-HGV no período de 2008 a 2011. Foram coletados dados de idade, gênero e causa do óbito do doador, tempo de enucleação, tempo de preservação, qualidade da córnea doada, causas de descartes e indicações de transplante de córnea no BTOC. Resultados: Foram analisadas 311 fichas de doadores de córnea do BTOC-HGV. O número de doações aumentou de 9 em 2008 para 80 em 2009, 109 em 2010 e 113 em 2011. A maioria dos doadores era do gênero masculino. A média da idade dos doadores foi de 43,00 ± 16,01 anos. A maioria das córneas transplantadas (78,6%) foi óptica. Foram descartadas 7,16% das córneas ópticas, sendo a maioria por nova classificação em tectônica e detecção de sorologia positiva. O tempo de enucleação foi de 3,77 ± 2,18 horas e o de preservação foi de 6,86 ± 6,10 horas. A causa mortis mais frequente foram causas externas, seguida por doenças do aparelho circulatório, respiratório, digestivo e geniturinário. A principal indicação de transplante foi ceratopatia bolhosa, seguida por ceratocone e perfuração corneana. Conclusão: Este estudo demonstrou a existência de fatores associados à qualidade das córneas captadas pelo BTOC como idade, tempo entre a enucleação e a preservação e causa do óbito. A principal indicação de transplante foi ceratopatia bolhosa. .
Objective: To describe the profile of corneal donations obtained by Ocular Tissue Bank, Hospital Getúlio Vargas (BTOC-HGV), assess the quality of the captured tissue and list the indications for corneal transplant. Methods: Retrospective study of registered donors in BTOC-HGV in the period 2008-2011. Collected data were: age, gender and cause of death of the donor, enucleation time, preservation time, quality of the donated cornea, causes of discards and indications for penetrating keratoplasty in BTOC. Results: Were analyzed 311 records of donor cornea BTOC-HGV. The number of donations increased from 9 in 2008 to 80 in 2009, 109 in 2010 and 113 in 2011. Most donors were male. The average age of the donors was 43.00 ± 16.01 years. The majority of transplanted corneas (78.6%) was optics. Were discarded 7.16% of corneal optics, mostly by new tectonic classification and detection of positive serology. The time of enucleation was 3.77 ± 2.18 hours and preservation was 6.86 ± 6.10 hours. The most frequent causes of death were external causes, followed by diseases of the circulatory, respiratory, digestive and genitourinary systems. The main indication for transplantation was bullous keratopathy, followed by keratoconus and corneal perforation. Conclusion: This study demonstrated the existence of factors associated with quality of corneas by BTOC as age, time between enucleation and preservation and cause of death. The main indication for transplantation was bullous keratopathy. .
