Four types of developmental pathway of LMH. A (Type 1): The LMH develops via disruption of the inner lining of an intraretinal cyst from vitreo-foveal traction. B (Type 2): The formation of foveoschisis causes the inner medial wall of the fovea to rupture. C (Type 3): The rupture of a taut and flat ERM leads to an intraretinal cyst. The rupture of the cyst causes LMH. D (Type4): The development of a fovea-sparing ERM in macular area elevates the macula, which subsequently causes tissue loss in fovea and forms the LMH without forming an intraretinal cyst. At the bottom of each column is B-FAF image, showing hyper-auto fluorescence signal, as supportive evidence for LMH
