Inverted internal limiting membrane flap technique for macular hole retinal detachment of high myopia / 中华眼底病杂志

ABSTRACT

The reattachment rate,macular hole (MH) closure rate,visual acuity improvement and redetachment rate of MH retinal detachment (MHRD) of high myopia are not satisfactory owing to long axis oculi,posterior scleral staphyloma and macular atrophy.At present,minimally invasive vitrectomy surgery combined with the internal limiting membrane flap technique has become popular in the treatment of MHRD,as it can promote MH closure,and significantly improve the outcome of MHRD.However if this method can improve the postoperative visual function is still controversial.The advantage of this technique is that the loosened internal limiting membrane is applied to cover the MH surface to form a scaffold structure similar to the basement membrane.It can stimulate Müller cell gliosis more effectively,and promote tissue filling in the MH which results in MH closure.It can also promote retinal reattachment and reduce the likelihood of retinal redetachment.This technique is expected to be a standard surgical method for the treatment of MHRD of high myopia in the future.The inserted internal limiting membrane flap technique is relatively easy to perform,induces stable flaps by simple procedures,and can be an essential complement procedure of the inverted internal limiting membrane flap technique.In order to reduce the recurrence rate in the future,it is necessary to further define the indications of different surgical methods and the predictive effects of MH healing mode on the success rate and visual function recovery.
