All measurements are expressed as a percentage of thereference length which is in this study the distance between dorsum sellae and the torcula herophili. The distancebetween dorsum sellae and medial choroidal artery as a percentage of reference length is designated as measurementA and that of lateral choroidal artery is measurement B. Measurement C is a percentage of interchoroidal distanceto the reference length. Normal value of measurement A is 47.8%+3.43, B 56.0%+3.83 and C 8.2%+2.62 Discussion onchanges in pathologic state is added.
