WebMar 1, 2024 · There is a consensus that the SD-OCT is the most sensitive way of identifying buried optic disc drusen. En face SD-OCT is especially effective at detecting peripapillary wrinkles and outer retinal creases, both of which are common and distinctive signs of optic disc edema that rule out pseudopapilledema. WebOnce papilledema is diagnosed, it is often difficult to determine whether a reduction in optic nerve edema is due solely to improvement in the status of the nerve or whether this represents concomitant loss of axons and viable retinal ganglion cells, leading to a poor visual outcome.

WebHistopathology of papilledema suggests that PHOMS might correspond to the lateral bulging or herniation of distended axons into the peripapillary retina. Thus, PHOMS shouldn't be diagnosed as ODD, unless there was histopathological evidence to the contrary[1].
