[A case of morning glory syndrome associated with contractile movement of the optic disc and subretinal neovascularization].

We report a rare case of morning glory syndrome with choroidal neovascular membrane and contractile movement of the optic disc. A 12-year-old healthy boy was first seen in April 1992 with a chief complaint of transient visual loss in his left eye for 3 months. The diagnosis of morning glory syndrome was made by the characteristic optic nerve head. His visual acuity was 1.2 in both eyes. In August 1994, retinal hemorrhage associated with choroidal neovascular membrane was observed in the macula of his left eye, resulting in a decrease of visual acuity to 0.4. In October 1994, we observed contractile movement in the morning glory optic disc. Using a scanning laser ophthalmoscope (SLO), we could observe the disc contracting for approximately 2 seconds and then dilating again over a 20-second period. The contractile movement was not evoked by exposure to a strong light or by the Valsalva maneuver. However, it seemed to be induced by digital massage of the eyeball.
