The cupping theory was mistakenly introduced in the 1850s. One hundred years later, instead of confirming the cupping theory, we introduced a cup-to-disc ratio parameter which inferred that the original (birth) cups begin enlarging as the disease progresses. However, the original cups of various sizes from 0.00 to 0.9 are actually the central meniscus of Kuhnt (fibrous remnants of Bergmeister’s papilla) which lie superficially on the nerve fiber layer of the disc, and have no relevance to this disease. There is no cupping in primary open-angle glaucoma. The lamina cribrosa is sinking resulting in the peripheral-to-central axotomy of nerve fibers at the scleral edge.

Thanks for your interest and comment. The term "cupping" in this talk (and in the English-speaking ophthalmology world) simply refers to the physical change (enlargement of the cup-to-disc ratio) of the ONH in glaucoma. I have actually never heard of a "cupping theory." I'm curious. Can you point me to a reference that talks about cupping theory?
