[Early glaucomatous changes in neuroretinal rim shape].
OBJECTIVE
To assess the differences in neuroretinal rim shape in ocular hypertensive patients (normal white-white automated perimetry) with and without perimetric injury in the short wave length automated perimetry (blue-yellow).


METHODS
72 eyes from 72 hypertensive ocular patients with normal achromatic automated perimetry examination were included. Forty eyes had normal short wave length automated perimetries while 32 subjects presented an abnormal condition. The neuroretinal rim morphology was quantified by means of a planimetric study from the papillary images obtained with confocal laser scanning.


RESULTS
The subjects with abnormal blue-yellow perimetry showed a decrease in the neuroretinal rim area in the inferior and temporal positions. The differences were significant (p<0.05) at the 9 o'clock position (below the middle line) and almost significant (p<0.10) at the 10 o'clock position.


CONCLUSIONS
There are differences in the neuroretinal rim shape in ocular hypertensive subjects with normal achromatic perimetry according to whether there are abnormalities in the blue-yellow perimetry.
