    Dec 21, 2019 · In the case of gas filling, a MH smaller than 400 μm was enough to achieve successful anatomic healing without the need for the prone position . This finding may depend on the hydration theory that the subfoveal subretinal fluid is pumped out by the retinal pigment epithelium quickly, once traction is relieved . However, for MHs larger than 400 μm, although the tangential force was removed by ILM peeling, the MH was also difficult to heal.
