Purpose:
To compare the surgical results of vitrectomy with untreated or pretreated lyophilized human amniotic membrane grafts covering in treating retinal detachment related to posterior retinal breaks above chorioretinal atrophy in pathologic myopia.
Methods:
Nineteen patients with retinal detachment related to macular hole (MH) located above macular atrophy and/or posterior paravascular retinal breaks (PRBs) located above patchy chorioretinal atrophy in pathologic myopia were included. The eyes of these patients underwent vitrectomy with untreated lyophilized human amniotic membrane covering (n = 10) or perfluorocarbon liquid (PFCL)-assisted pretreated lyophilized human amniotic membrane covering (n = 9; grafts were pretreated in 0.125% indocyanine green and 50% hypertonic glucose solution for 15-20 minutes). The closure of the MH or PRBs, reattachment of the retina, and best-corrected visual acuity were measured postoperatively.
Results:
Postoperatively, graft dislocation or shift was only found in two eyes (20%) in the untreated group. The closure rate of the MH or PRBs was 80% (8/10) and 100% (9/9) in the untreated group and the pretreated group, respectively. The occurrence rate of excessive gliosis was 40% and 11% in the untreated group and the pretreated group, respectively. In both groups, best-corrected visual acuity was improved and the retinal reattachment rate was 100% at the final visit.
Conclusion:
Perfluorocarbon liquid-assisted pretreated lyophilized human amniotic membrane graft covering was effective in treating retinal detachment related to MH and/or PRBs situated above macular atrophy or patchy chorioretinal atrophy in pathologic myopia. This technique appeared to reduce graft dislocation or shift, promote the closures of MHs/PRBs, and reduce the occurrence of gliosis.
