ABSTRACT
Abstract

Objective:

To evaluate the clinical effectiveness of amniotic membrane transplantation for ocular surface reconstruction.

Methods:

Prospective study including 23 eyes of 21 patients who underwent amniotic membrane transplantation at Hospital de Clínicas da Universidade Federal do Paraná (HC-UFPR) and at Cirurgia e Diagnose em Oftalmologia do Paraná (CDOP) clinic, located in Curitiba, PR, Brazil, from may 2015 to july 2019. The amniotic membrane was collected from elective and term cesarean delivery, and conserved in preservation medium and glycerol 11, stored at -80° Celsius. The membrane was fixed on the ocular surface with 10-0 nylon, 8-0 vicryl, biological glue or a combination of these materials.

Results:

The ocular surface reconstruction was successful in 22 eyes (95.6%). Failure was observed only in 1 case (bullous keratopathy) in which the condition was maintained postoperatively. Patients' age ranged from 11-82 years, with a mean age of 37.4 years. There was a higher incidence in males (66.6%). A difference was perceived in the distribution of the affected eye (which was greater in the right eye - 65.2%). As for the previous ophthalmic surgery history, 12 of the 23 eyes had a positive history (52.2%). It was observed that all patients who had preoperative visual acuity assessed showed improvement or maintenance of corrected visual acuity. In the postoperative period, complications associated with the underlying disease were observed, although not particularly related to the amniotic membrane transplantation. There were not any cases of postoperative infection.

Conclusions:

There was an improvement in the general state of the ocular surface in almost all of the cases in which the transplant was performed. Therefore, the amniotic membrane can be considered a good alternative for reconstructing the ocular surface, as a single or supporting treatment.
RESUMO
Resumo

Objetivo:

Avaliar a eficácia clínica do transplante de membrana amniótica na reconstrução da superfície ocular.

Métodos:

Estudo prospectivo incluiu 23 olhos de 21 pacientes que realizaram transplante de membrana amniótica no Hospital de Clínicas da Universidade Federal do Paraná (UFPR) e na clínica de Cirurgia e Diagnose em Oftalmologia do Paraná (CDOP), localizados em Curitiba, PR, Brasil, no período de maio de 2015 a julho de 2019. A membrana amniótica foi captada a partir de parto cesárea eletivo e a termo, conservada em meio de preservação e glicerol 11 e armazenada a -80° Celsius. A membrana foi fixada na superfície ocular com fio nylon 10-0 ou vicryl 8-0 e/ou cola biológica.

Resultados:

A idade dos pacientes variou de 11-82 anos, com média de 37,4 anos. Houve maior incidência no sexo masculino (66,6%). Ocorreu diferença na distribuição do olho acometido (maior no olho direito - 65,2%). Quanto à história de cirurgia oftalmológica prévia, 12 dos 23 olhos tinham história positiva (52,2%). Observamos que nos pacientes em que foi possível a avaliação da acuidade visual pré-operatória, todos apresentaram melhora ou manutenção da acuidade visual. No pós-operatório foi observado complicações associadas à doença de base e não propriamente ao transplante de membrana amniótica. Não foram registrados casos de infecção pós-operatória.

Conclusão:

Houve melhora do estado geral da superfície ocular em quase totalidade dos casos em que o transplante foi realizado. Portanto, a membrana amniótica pode ser considerada uma boa alternativa para reconstrução da superfície ocular, como tratamento único ou coadjuvante.
