Optic disc pallor and visual field defect in exfoliative and non-exfoliative, untreated ocular hypertension

In a prospective study of untreated ocular hypertension 117 eyes were non-exfoliative and 20 eyes exfoliative. The percentage of optic disc pallor was significantly larger in the exfoliative than in the non-exfoliative group, whereas no significant differences were found in IOP or in the visual field.
