ABSTRACT
ABSTRACT

Purpose:

To evaluate the clinical results of patients treated by amniotic membrane transplantation (AMT) following excision of conjunctival and limbal tumors.

Methods:

A total of 14 eyes of 14 patients who underwent AMT after total lesion-free tumor excision and perilesional cryotherapy were evaluated.

Results:

The excised tumors comprised 7 conjunctival intraepithelial neoplasia, 5 conjunctival nevus, 1 primary acquired melanosis, and 1 squamous cell carcinoma. Limbus was involved in 10 cases, whereas cornea was involved in 6 cases. The average measurement of the tumor base was 14.8 mm (range 6-20 mm, SD 16 mm). The mean follow-up time period was 17.5 months (range 6 -60 months, SD 20 months). Complete healing occurred in eight eyes, but limbal cell deficiency developed in two eyes. Four cases had recurrence and were treated with the same surgical and medical procedures; during follow-up after recurrence, superficial peripheral vascularization and corneal scar were noted to have developed.

Conclusions:

AMT was effective for reconstruction of tissue defect after excision and cryotherapy of limbal and conjunctival tumors. In most of these cases, complete healing was achieved with a smooth, stable, and translucent surface.
RESUMO
RESUMO

Objetivo:

Avaliar os resultados clínicos de pacientes tratados com transplante de membrana amniótica (TMA) após a excisão de tumores conjuntival e limbar.

Métodos:

Foram avaliados 14 olhos de 14 pacientes submetidos a transplante de membrana amniótica após excisão total de tumor e crioterapia perilesional.

Resultados:

Os tumores que foram excisados podem ser classificados como neoplasia intraepitelial conjuntival em 7, nevus conjuntival em 5, melanose adquirida primária e carcinoma espinocelular em 1 caso cada. O limbo foi envolvido em 10 casos e a córnea foi envolvida em 6 casos. A medida média da base do tumor foi de 14,8 mm (6-20, DP 16). O tempo médio de seguimento foi de 17,5 meses (6-60, DP 20). A cicatrização completa ocorreu em 8 olhos e deficiência de células limbares ocorreu em 2 olhos. A recorrência foi diagnosticada em 4 casos e tratada com o mesmo procedimento cirúrgico e médico e, após essa recorrência, a vascularização periférica superficial e a cicatriz corneana desenvolveram-se em 4 casos durante o seguimento.

Conclusões:

O transplante de membrana amniótica é um método eficaz para a reconstrução do defeito do tecido após a excisão de tumores limbares e conjuntivais com a combinação de crioterapia. Na maioria destes casos, a cicatrização completa pode ser conseguida com uma superfície lisa, estável e transparente.
