Abstract: Munchausen syndrome,  a kind of factitious disorder,  belongs to mental illness. It mainly refers to the syndrome in which the patient,  by imitating or creating physical symptoms or signs,  pretends to be a sick personfor the purpose of seeking medical help and getting attention. Clinical presentation of Munchausen syndrome can start with ocular symptoms or only involve ocular tissue. The form is various,  such as intraocular foreign bodies,  ocular pain without causes,  spontaneous dislocated eyeball and rupture of eyeball caused by self-injury. In severe cases vision loss,  enucleation and other adverse outcomes can be caused. Most ophthalmic clinicians have low recognition and vigilance for Munchausen syndrome,  so there are great challenges in its early diagnosis and treatment. (Int Rev Ophthalmol,  2021,  45: 560-564)
