Background
- an inflammatory, demyelinating condition highly associated with multiple sclerosis (MS)
- presenting feature of MS in 15 to 20 percent of patients and occurs in 50 percent at some time during the course of their illness
Diagnosis
- acute, usually monocular, visual loss-usually monocular (90%)
- vision loss (over hours to days; peaking within 1-2 wks)
- eye pain (92%), often worsened with eye movement
- afferent pupillary defect-visual field defect (typically central scotoma)-papillitis (33%)
- with hyperemia and swelling of the disk, blurring of disk margins, and distended veins-photopsias (30%) (flickering or flashes of light) often precipitated with eye movement
- loss of color of vision out of proportion to the loss of visual acuity is specific
