Membrane on the back Side of the ILM Causing Pucker-like Distortions

Bernd Kirchhof
Even though the ILM stains homogenously the ILM is distorted like in a pucker. The explanation is that the causative membrane resides on the back side of the ILM and bridges to the retina, possibly glial tissue. Thus ILM is a substrate and precondition for membrane formation not matter on which side of the ILM membranes develop.
