It is known that changes in pattern electroretinogram (PERG) and optic disk morphology may both precede the onset of visual field damage in glaucomatous disease. However, the relationship between PERG and optic disk morphometry in ocular hypertension (OHT) has not yet been evaluated in detail. This study of PERG amplitude in a group of OHT patients indicates its significant correlation with various optic disk morphometric parameters, in particular, those of optic disk sectors considered at risk for early glaucomatous damage. Analysis of individual data points to the possibility that, while functional abnormalities may often precede optic disk morphologic changes, in a much lower number of cases it seems to be the other way around.
