Avaliação de tecido corneano processado por um Banco de Olhos de referência

OBJETIVO: Avaliar a qualidade das corneas processadas pelo Banco de Olhos de Sorocaba - SP e transplantadas fora do Hospital Oftalmologico de Sorocaba, bem como das corneas que tiveram reentrada no Banco de Olhos de Sorocaba durante o ano de 2007. METODOS: Foram contatados os oftalmologistas que transplantaram corneas captadas pelo Banco de Olhos de Sorocaba fora do Hospital Oftalmologico de Sorocaba, bem como os que utilizaram corneas reentradas, a fim de colher as seguintes informacoes: periodo desde a captacao da cornea ate o transplante, transparencia do tecido doador, tempo de transplante e falencia primaria. RESULTADOS: Trezentas e noventa e duas corneas tiveram saida do Banco de Olhos de Sorocaba ao longo do ano de 2007. Dessas, 6 retornaram ao Banco de Olhos de Sorocaba e foram transplantadas no Hospital Oftalmologico de Sorocaba, sendo que nenhuma foi rejeitada; todavia, 2 apresentaram alguma opacidade no eixo visual. Apos tentativa de reunir informacoes a respeito das 386 corneas transplantadas fora do Hospital Oftalmologico de Sorocaba, obtiveram-se dados apenas de 48 transplantes. O tempo medio desde a captacao ate o transplante foi de 5,5 dias (1-13 dias), e o de seguimento medio pos-operatorio, de 9,8 meses (4-15 meses). Tres corneas desenvolveram falencia primaria, 3 evoluiram com opacidade no eixo visual, 1 apresentou ceratite infecciosa que necessitou de transplante tectonico; 1 paciente faleceu e 1 perdeu seguimento. As demais 39 corneas apresentavam-se transparentes. CONCLUSAO: Por causa das dificuldades de reunir as informacoes dos pacientes transplantados em outros hospitais, torna-se dificil definir a qualidade das corneas liberadas pelo Banco de Olhos de Sorocaba. Assim, outras analises como as desse estudo sao necessarias a fim de definir mudancas e rumos para estudos futuros sobre selecao e conservacao das corneas doadas. PURPOSE: To evaluate the quality of the corneas processed by Sorocaba Eye Bank (BOS) - SP and transplanted out of the Ophthalmology Hospital of Sorocaba (HOS), as well as the corneas that had re-entered in the BOS, being transplanted or not in the HOS, during the year of 2007. METHODS: Ophthalmologists that transplanted corneas processed by BOS outside of the Ophthalmology Hospital of Sorocaba were contacted, as well as those who had used re-entried corneas, to collect the following information: period from eye enucleation until transplant, transparency of the donated tissue, time of transplant and primary failure. RESULTS: During the year of 2007, Sorocaba Eye Bank distributed three hundred and ninety-two corneas for outside HOS. From these, six had returned to BOS and had been transplanted in the Ophthalmology Hospital of Sorocaba. From those, none was rejected; however, two presented some opacity in the visual axis. After attempt to congregate information regarding the 386 transplanted corneas outside HOS, data of only 48 keratoplasty were available. The average time from the enucleation until the keratoplasty was of 5.5 days (1-13 days), and of postoperative average follow-up, 9.8 months (4-15 months). Three corneas had developed primary failure; three presented opacity in the visual axis; one presented infectious keratitis, requiring therapeutic keratoplasty; a patient died and another one lost follow-up. The other 39 corneas did not present any problems until the time this study was ended. CONCLUSION: Because of the difficulties to congregate informations of the patients transplanted in other hospitals, it is difficult to define the quality of the distributed corneas by Sorocaba Eye Bank. Thus, other analysis are necessary in order to define changes and new directions for future studies on selection and preservation of donated corneas.
