Changes in retinal sensitivity following inverted internal limiting membrane flap technique for large macular holes
PURPOSE: The aim of this study was to evaluate the effect of inverted internal limiting membrane (ILM) flap technique and measure the retinal sensitivity using microperimetry-1 (MP-1) test in patients with large macular hole (MH). MATERIALS AND METHODS: We enrolled patients undergoing surgery for id...

MATERIALS AND METHODS: We enrolled patients undergoing surgery for idiopathic MHs from January 2016 to October 2019. Only patients having a minimum diameter of idiopathic MH exceeding 500 μm were included in this study. All patients underwent complete preoperative ophthalmologic examinations, optical coherence tomography (OCT), and best-corrected visual acuity (BCVA) measurements. Postoperative OCT and BCVA were evaluated at least 3 months postoperatively. In addition, these patients also received MP-1 pre- and postoperatively for retinal sensitivity measurement. RESULTS: Totally ten patients (ten eyes) were included for analysis. The mean retinal sensitivity within central 12° and 40° was statistically improved after surgery (P < 0.05). The number of absolute or relative scotoma (stimulus values ≤4 dB) within central 4° showed a significant reduction postoperatively. There was also a significant increase in visual acuity postoperatively. CONCLUSION: Patients with large MH have a great successful rate by receiving inverted ILM flap technique. In our study, all MHs of ten eyes were closed postoperatively. The results also demonstrated that ILM flap technique improves both the functional and anatomic outcomes.http://www.e-tjo.org/article.asp?issn=2211-5056;year=2021;volume=11;issue=3;spage=273;epage=279;aulast=Huanginverted internal limiting membrane flap techniquelarge macular holemicroperimetermicroperimetry-1retinal sensitivityvitrectomy |
