FIG 5. Plot of enhancement in 44 optic nerves (37 patients). Each horizontal line represents the area of enhancement in a single nerve. The distance from zero on the x-axis to the left end of the line represents length (if any) of nonenhancing nerve adjacent to the globe. The length of the line itself represents the extent of enhancement. The 5 enhancing nerves in patients with optic neuropathy due to cat scratch disease are at the bottom (bold lines). The other 39 enhancing nerves with optic neuropathy from other causes are above these (thin lines). The one patient with false-positive findings is marked as a short thin line just above the patients with cat scratch disease.
