Case 4-7. Epiretinal Membrane
An 84-year-old man had a visual acuity of 20/200 in his left eye associated with the clinical diagnosis of an epiretinal membrane in the macular area. Dilated ophthalmoscopy (A) showed straightening of the retinal arterioles superior to the fovea.
The OCT scan (B) showed the presence of a highly reflective membrane on the surface of the retina. The neurosensory layer of the fovea appeared to be disrupted, and small areas of minimal backscattering were observed within the neurosensory retina corresponding to macular edema. A vitreal displacement of the choroid and retina was also apparent, either due to the presence of macular edema or traction of the epiretinal membrane on the retina.

Case 4-8. Epiretinal Membrane and Macular Edema
A 75-year-old man had macular edema associated with an epiretinal membrane in his right eye (A). His visual acuity was 20/100 through a pinhole.
A vertical OCT tomogram (B) was acquired through the macula- The membrane appears in the image as a thin, reflective band just anterior to the neurosensory retina and attached to the macula. A moderately sized, non-reflec- A
tive cyst was visible directly in the fovea and a diffuse increase in retinal thickness was noted which reached a maximum of 480 \Lm in the fovea.
