Excerpt
In 1925 [

5]. The basic premise is that in raised CSFP, the lamina cribrosa bows forward to cause optic disc edema, while a fall in CSFP would cause the reverse, i.e., a bowing back of the lamina cribrosa and cupping. To assess the scientific rationale behind this notion, one has to consider the following fundamental relevant issues. …
