To study the clinical outcomes, time span of healing of various ocular surface disorders with amniotic membrane graft.
A total of 41 patients, presenting to cornea clinic were included in the study and divided into five groups depending on the type of diagnosis: Group 1, with either >2 weeks of Persistent epithelial defect following cataract/retinal/glaucoma surgeries or Shield ulcers, Group 2 with >4 weeks of Non healing corneal ulcers, Group 3 with chemical injuries, Group 4 with Epithelial defects following keratoplasty, and Group 5 is the miscellaneous group.
The mean age of the study subjects was 50.0 years. Overall mean duration between clinical presentation and AMT was 23.59 (30.7) days, a median 16 days (IQR; 2-26 days). Failure rate was high in Group 5 (n = 3: 30.0%) and Group 2 (n = 3: 27.3%). Time taken for epithelial closure was slower in groups 1 and 5 patients. The average time taken for reabsorption of AMG was 14.98 days. The complications included repeat AMG was in four eyes (9.75%), and graft displacement was noted in four eyes (9.75%) required resuturing, three eyes required TPK (7.31%), and one eye underwent evisceration (2.43%) following severe corneal melt secondary to neurotropic ulcer. The mean log MAR visual acuity improved from 1.52 to 1.26 at the 3 months.
Understanding on timespan for healing of ocular surface disorders with AMG is needed to assess the prognosis of the disease, preoperative counselling for repeat procedures, and the compliance with regard to follow up.
研究羊膜移植治疗各种眼表疾病的临床疗效和愈合时间。
共纳入 41 例就诊于角膜科的患者,根据诊断类型分为五组:第 1 组为白内障/视网膜/青光眼手术后持续性上皮缺损或盾状溃疡超过 2 周;第 2 组为非愈合性角膜溃疡超过 4 周;第 3 组为化学伤;第 4 组为角膜移植术后上皮缺损;第 5 组为其他。
研究对象的平均年龄为 50.0 岁。总体上,从临床症状出现到 AMT 的平均时间为 23.59(30.7)天,中位数为 16 天(IQR;2-26 天)。第 5 组(n=3:30.0%)和第 2 组(n=3:27.3%)的失败率较高。第 1 组和第 5 组患者的上皮愈合时间较慢。羊膜吸收的平均时间为 14.98 天。并发症包括 4 只眼(9.75%)需要再次行 AMG,4 只眼(9.75%)发生羊膜移位需要重新缝合,3 只眼需要行穿透性角膜移植术(7.31%),1 只眼因神经源性溃疡导致严重角膜融解后行眼内容剜除术(2.43%)。3 个月时平均 logMAR 视力从 1.52 提高到 1.26。
了解羊膜移植治疗眼表疾病的愈合时间对于评估疾病预后、术前重复手术咨询以及随访依从性非常重要。
