Epiretinal Membrane and Pseudohole: Caught in the Act

Occasionally, an epiretinal membrane (a thin sheet of fibrous tissue) will form on the inner limiting membrane interface on the retina, contract over time and form what looks for all the world like a macular hole. These require no treatment unless acuity is poor enough- then in the skilled hands of a vitreoretinal surgeon the epiretinal membrane can be peeled off. 

Here are some great images of this membrane and the resultant pseudohole which we were able to image in the practice recently. It required no attention at present, but we'll watch it regularly. 

The Zeiss Cirrus HD-OCT allows us to cut sections through the imaged tissue to explore the retina in 3-D.
