Amongthem, 4 cases(4 eyes)were male and 8 cases(8 eyes) female, ranging in age between 26and 51 years[mean(41 ± 3)years]. Three eyes recurred once, 5 eyes twice, and 4 eyesthree before. Eleven of 12 cases (11/12 eyes)with frequently recurrent Mooren's ulcerunderwent lamellar keratoplasty combined amniotic membrane transplantation(AMT).One patient who had entire corneal ulceration accepted AMT alone.Results: Follow-up time is 12 to 29 months, [mean (23 ± 6) months]. Before AMT, therecurrent frequency of Mooren's Ulcer of all cases after corneal surgery was 1 ～ 7 months[mean(3 ± 2)months]. Nine of 12 eyes with lamellar keratoplasty combined AMT did notrecur within the observation period; 2 eyes recurred 11 months after the surgery. Threemonths postoperatively, neovascularization was observed, which made it nearly impossibleto decipher between amniotic membrane and its nearby conjunctiva, only at the junctionof the transplant can some trails be observed. One case with entire AMT alone showedgraft resolution and neovascularization in 1 month.Conclusion:AMT combined with lamellar keratoplasty and lesion excision may delayrecurrence of Mooren's Ulcer, reduce its recurrent frequency. Besides the effects ofdecreasing inflammation, it may have immunological insulating function as well. Thisconclusion should be proven by further clinical comparative study of much moresamples.展开更多
