[Sensory physiology and biomorphology of the optic papilla: analysis of correlation in normal persons]
1DFG-Klinische Forschergruppe Glaukome (Na 55/6-2), Universität Erlangen-Nürnberg.
Background:
The aim of the present study was to investigate whether the morphological variability of the optic disc has an influence on sensory test procedures.
Patients And Methods:
In 52 eyes of 52 normal persons psychophysical (perimetry, color vision, contrast sensitivity) and electrophysiological (pattern-ERG and pattern-VEP) tests and planimetric papillometry were performed. A correlation analysis was made between sensory tests and area of optic disc (1.79 to 5.2 mm2) and neuroretinal rim.
Results:
There was no significant correlation between perimetry, color vision, pattern-ERG, pattern-VEP, spatio-temporal and temporal contrast sensitivity on the one hand and optic disc area or neuroretinal rim area on the other.
Conclusion:
Results of psychophysical and electrophysiological tests do not have to be corrected with respect to the neuroretinal rim area.
