Objective:
To evaluate the risks that might be associated with recurrent macular hole retinal detachment (MHRD) after silicone oil (S.O) removal in myopic patients with open flat macular hole (MH).
Methods:
In this retrospective series, we assessed the different factors that might be associated with recurrent MHRD after S.O removal in 48 eyes with open flat MH that underwent S.O removal after successful MHRD repair. We divided the enrolled eyes into 2 groups: group 1 included 38 eyes with flat open MH and flat retina after S.O removal, and group 2 included 10 eyes with flat open MH and recurrent MHRD after S.O removal.
Results:
Ten of 48 eyes (20.8%) with open flat MH developed recurrent MHRD after S.O removal. Univariate logistic regression analysis revealed 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.
Conclusions:
If there is a "flat open" MH that is large, located at the apex of PS, or with an HHF or MHI <0.9-0.5, there is a high chance of recurrent MHRD after S.O removal.
