Abstract
Cilioretinal arteries were noted to accompany pits of the optic disc in 16 of 25 cases (64%). Fourteen of the 16 cases were found to have 2 cilioretinal arteries (86%). The cilioretinal arteries were directly related to the pit of the disc and emerged either from the bottom or the margin of the pit in a proportion of 86%. This finding reinforces the assumption that the optic disc pit belongs to the same spectrum of congenital anomalies which also includes optic disc coloboma, megalopapilla and morning glory syndrome. A fluorescein angiography study showed hyperfluorescence of the pit in 12/16 cases and in particular in all the cases in which both cilioretinal arteries emerged from the pit. Hypofluorescence was noted in 7/9 cases in which the pit was not associated with cilioretinal arteries. Our findings could support the view that hyperfluorescence of the pit, which is not a constant phenomenon, mostly depends on the presence of cilioretinal arteries emerging from the pit.
