Case 3-27. Vitreomacular Traction
An 87-year-old woman with age-related macular degeneration had a visual acuity of 20/80 in her right eye (A), A partial posterior vitreous detachment was noted with an area of vitreous traction along the superotemporal vascular arcade.
A linear scan (B; white line on A) through the macula displayed retinal thickening and a large cyst in the fovea above an apparently intact photoreceptor layer A reflective membrane appeared to be exhibiting traction on the superior macula. The high reflectivity of this membrane was more consistent with preretinal fibrosis than the posterior hyaloid. A second vertical tomogram temporal to the fovea (C; black line on A) demonstrated the vitreoreti-
nal traction that was observed clinicallv.
