[Computer controlled analysis of the optic papilla in patients with anterior ischemic optic neuropathy].
BACKGROUND
In patients with non-arteritic anterior ischaemic optic neuropathy disc parameters have been measured with a largely objective method (Optic Nerve Head Analyzer). We wanted to find out, whether the measurements of different disc parameters allow an assertion of predisposition to AION.


METHODS
Measurements have been done with the Optic Nerve Head Analyzer (ONHA). In 25 patients with AION disc area and neuroretinal rim area was measured in the nonaffected fellow eye. The results were compared to those of 19 healthy subjects. In 12 of the 25 patients the disc structure of the AION-eye was measured over time with an average of 4 measurements in 16 months.


RESULTS
1) Disc area and neuroretinal rim area of the AION-eyes do not differ significantly from those of the healthy subjects. 2) Disc area and neuroretinal rim area of the healthy fellow eyes of the AION patients were not significantly different from those of the healthy subjects. 3) Measurements of disc parameters over time did not show significant differences between the parameters of the beginning of AION and after 16 months.


CONCLUSIONS
Measurements of disc area and neuroretinal rim area with the Optic Nerve Head Analyzer do not allow assertions of predisposition to AION.
