Epiretinal proliferation (EP) is thought to be glial cell proliferation arising from the inner retina, seen in cases of lamellar or full-thickness macular holes (FTMH). Embedding EP within the macular hole is considered supportive for FTMH closure and functional recovery. We report a recurrent case of FTMH that was successfully closed after primary vitrectomy with the EP embedding technique. In the primary surgery, internal limiting membrane (ILM) peeling was avoided to reduce the potential risk of retinal nerve fiber layer damage associated with glaucoma. The FTMH was successfully closed, with complete recovery of macular layer structures. However, over one year later, the FTMH reopened, slightly dislocated from the position of the embedded EP scar. The reopened FTMH was closed again after the second surgery using the ILM inverted flap technique. This case indicates that macular hole closure with EP might not sufficiently support the tissue repair of FTMH as a new hole can form if tangential traction of the ILM remains.
