A case of myelodysplastic syndrome (MDS) who suffered alternating proptosis was reported. A 57-year-old Japanese man with MDS developed acute painful left proptosis with eyelid edema, conjunctival injection, visual disturbance, and restriction of eye movements. This lasted for 3 weeks. Computerized tomography (CT) showed swelling of the lateral and medial rectus muscles and the optic nerve, as well as a retrobulbar mass. Later, a similar painful right proptosis with severe conjunctival chemosis developed. CT showed only bilateral mild optic nerve swelling. The visual acuity of the right eye decreased to null even after remission of the proptosis. The patient died due to myocardial infarction and underwent autopsy. The right optic nerve stroma was found to be increased over that of the left. Cellular infiltration was noted in the left optic nerve and the retrobulbar connective tissue. This self-limiting and relapsing proptosis was apparently related to MDS. This is only the second MDS case with such severe ophthalmological symptoms reported in the literature.

D005654	Fundus Oculi	The concave interior of the eye, consisting of the retina, the choroid, the sclera, the optic disk, and blood vessels, seen by means of the ophthalmoscope. (Cline et al., Dictionary of Visual Science, 4th ed)	Fundus of the Eye,Ocular Fundus,Fundus, Ocular

D014792	Visual Acuity	Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.	Acuities, Visual,Acuity, Visual,Visual Acuities
