We have been performed amniotic membrane transplantation in 18 patients (20 eyes) with 23 operations (3 eyes were regrafted). One month after operation, 90% of the eyes had exellent result, 10% were good. Three months following the transplantation of amniotic membrane, 10 of 17 eyes had excellent result, in 4 of 14 eyes, the symblepharon was reduced. 6 months after the procedure showed that 9 of 14 eyes had excellent result and only 1 eye had recurrence. The sudy showed that human amniotic membrane is good material for reconstruction ocular surface in severe symblepharon. In the eyes with successful transplantation, ocular surface was covered with a soft, thin membrane with vascularization as natural conjunctiva. The material can be easily taken at anytime. The procedure can be applied in every ophthalmological department of provincial hospitals.

PURPOSE: To evaluate the effect of amniotic membrane and additional use of 2% methylcellulose(Methocel(R)) in reducing the postoperative adhesions following strabismus surgery. METHODS: Twenty white rabbits (40 eyes) were divided into 4 groups: control group C (12 eyes), trial group A (12 eyes), trial group B (12 eyes), and normal group N (4 eyes). In group C, the superior rectus was detached and scleral scratching was done to provoke a fibrotic reaction, and then, the superior rectus was reattached to the original insertion site. In group A, the above procedure was done and in addition, the superior rectus was covered with two-folded amniotic membrane. In group B, the same procedure was done as in group A and in addition, Methocel(R) was coated between the muscle and adjacent tissues. Eight weeks later, we divided each group into two subgroups. In one group, we examined the degree of adhesion by the blunt dissection between the muscle and adjacent tissues, and in the other group, the histologic findings with a light microscope between the muscle and adjacent tissues. RESULTS: The adhesion degree on the blunt dissection and histologic examination was significantly reduced in groups A and B. But no statistically significant difference between groups A and B was shown in the postoperative adhesion. CONCLUSIONS: From these findings, it is expected that the use of amniotic membrane may reduce the postoperative adhesion after strabismus surgery and theadditional use of Methocel(R) may not be useful.

Successful treatment of late-onset leakage of filtering bleb often requires conjunctival advancement or conjunctival graft with the risk of bleb failure. The authors performed amniotic membrane transplantation in two patients with Seidel-positive late-onset leakage of filtering bleb. In one patient, amniotic membrane transplantation(AMT)was performed twice. In the patient who underwent AMT twice, the bleb became Seidel-negative within 5 weeks of second AMT. However, it became Seidel-positive again within next 7 weeks. In the other patient, the bleb leak was partially resolved within 4 weeks, but became exuberant again within the next 4 weeks. In our experience, AMT had only a limited benefit in treating Seidel-positive bleb leaks. However, its initial success suggests that further studies are necessary to better understand the role of amniotic membrane in bleb leak and to develop a potential therapeutic modality for treating late-onset filtering bleb leak.

PURPOSE: We report the clinical efficacy of amniotic membrane transplantation which dyed by Chinese-ink and Davidson marking dye in patients of bullous keratopathy. METHODS: We performed permanent amniotic membrane transplantation in 23 eyes with bullous keratopathy during the period of October 1998 to May 2002. Simple amniotic membranes were transplanted in 9 eyes, Chinese-ink dyed amniotic membranes in 10 eyes, and Davidson marking dyed amniotic membranes in 4 eyes. RESULTS: 23 eyes were successfully transplanted by amniotic membrane. Most of patients with photophobia, pain, cosmetic problem had been satisfactory effects in Chinese-ink and Davidson marking dye groups and Davidson marking dye groups noted longer staining than Chinese-ink group. CONCLUSIONS: We suggest that dyed amniotic membrane transplantation may be effective method to release pain, photophobia, and cosmetic problem by stabilization of corneal surface than previous simple amniotic membrane transplantation in bullous keratopathy.
