COVID-19 is a disease that can be asymptomatic or characterized by cough, shortness of breath, and fever, causing pneumonia in some cases that can lead to death. There is currently no evidence that coronaviruses can transmit by transplanting tissue, cells, or transfusions, so measures in response to this are precautions, motivating continuous regulatory updating for the corneal tissue management procedure and corneal transplantation, based in the criteria adopted by various associations. This provides the security of obtaining corneal tissue through strict eligibility criteria supported by guidelines issued and studied, thus guaranteeing the protection of recipient patients. You must perform RT-PCR both in the donor (before death and up to 24 hours after death) as in the recipients. Although at the moment there is a temporary suspension of organ and tissue donation and transplantation programs nationwide and only corneal transplants are considered in urgent situations, the evaluation of the conditions in which the gradual start of the normal activity of corneal donations-procurement and transplant activity, minimizing the risk to recipients and health personnel involved.
Introducción: la pandemia de COVID-19, originada por SARS-CoV-2, ha generado un decremento en los programas de donación. La posibilidad de trasmisión es alta, por ende no se dispone de tejido corneal fresco. El objetivo de este artículo fue documentar los resultados terapéuticos al usar tejido corneal preservado en glicerina, en pacientes sometidos a trasplante corneal de urgencia. Material y métodos: estudio retrospectivo y descriptivo. Se documentó la evolución clínica de los casos atendidos por trasplante de córnea. Se incluyeron los expedientes de pacientes que hubieran sido sometidos a trasplante corneal de urgencia utilizando tejido corneal en glicerina. Se utilizó el programa estadístico SPSS y Excel. Resultados: un total de 19 pacientes; 13 (68.4%) fueron varones y seis (13.5%) mujeres. La principal indicación fue la úlcera corneal infecciosa en siete (36.8%) y perforadas en seis (31.5%). 17 casos (89.4%) lograron la conservación de la integridad ocular. Las complicaciones incluyeron glaucoma en uno (5.3%) y lisis de tejido corneal en tres (15.7%). Conclusiones: el tejido corneal preservado en glicerina es una buena opción para los trasplantes de córnea de urgencia, al mantener la integridad ocular y salvar el globo ocular cuando no se dispone de tejido corneal fresco.Palabras clave: trasplante de córnea, tejido corneal preservado en glicerina, tejido corneal fresco.
