Ghoraba HH, Mansour HO, Elsayed MAA, et al. - In this retrospective series, researchers sought to assess the risks that might be correlated with recurrent macular hole retinal detachment (Re MHRD) after silicone oil (S.O) removal in myopic patients with open flat macular hole (MH). According to results, 10 of 48 eyes (20.8%) with open flat MH developed recurrent MHRD after S.O removal. Univariate logistic regression analysis showed that MH at the apex of PS, MH minimum diameter, hole form factor (HFF) and MH index (MHI) were significant risk factors for recurrent MHRD after S.O removal in myopic patients with open flat MH. If there is a large 'flat open' MH located at the apex of PS or with HHF or MHI of less than 0.9-0.5, it has a high chance of recurrent MHRD after S.O removal.
