Abstract:

Idiopathic macular hole（IMH） is one of the common fundus diseases that cause central vision loss in patients. In recent years, with the advancement of surgical techniques，the postoperative closure rate improved gradually. The postoperative visual function was influenced by many factors, such as the height of macular hole(H), base diameter(BD), minimum linear diameter (MLD), preoperative hiatal morphology, operation method, hole-closed mophology and macular structure etc. Intraoperative factors, such as internal limiting membrane peeling, inner membrane flap and staining methods can also affect the closure rate and visual outcome.(Int Rev Ophthalmol, 2018, 42:  159-163)
