The clinical effect of amniotic membrane patching in the treatment of recurrent macular hole associated with retinal detachment of high myopia / 中华眼底病杂志

ABSTRACT

Objective:To evaluate the safety and efficacy of amniotic membrane patching in the treatment of recurrent macular hole associated with retinal detachment of high myopia (MHRD).Methods:A prospective study. From March 2018 to January 2020, 11 patients (11 eyes) of recurrent macular hole associated with MHRD at the First Affiliated Hospital of Zhengzhou University were enrolled. Among them, there were 3 males (3 eyes), and 8 females (8 eyes). The average age was 63.64±5.82. The axis length (AL) was 29.10± 0.59 mm, and the logarithm of the minimum angle of resolution best corrected visual acuity (logMAR BCVA) was 2.23±0.57. Patients previously received pars plana vitrectomy (PPV) combined with internal limiting membrane stripping surgery, which was more than 1 time. All eyes underwent standard pars plana three-channel 23G PPV combined with amniotic membrane covering and silicone oil filling. The silicone oil was removed 6 months after surgery. Follow-up time was up to 3 months after silicone oil removal surgery. 1, 3, and 6 months after the operation, the same equipment and methods were used to conduct relevant examinations before the operation to observe the closure of the macular hole, retinal reattachment and changes in logMAR BCVA. The logMAR BCVA before and after surgery was compared by paired t test. Results:At 1, 3, and 6 months after the operation, the retinas of all eyes were anatomically repositioned, the macular holes were well closed, and the amniotic membrane was attached to the retina. At 3 months after the silicone oil removal operation, there was no recurrence of macular hole in all eyes; logMAR BCVA was 1.35±0.32. No serious complications occurred during and after surgery in all eyes.Conclusion:Amniotic membrane patching is a safe and effective method for recurrent macular hole associated with MHRD.
