The visual fields of 40 high myopic eyes (-8.25D to -28.0D) with primary open angle glaucoma (POAG) were compared with those of 208 hyperopic, emmetropic and myopic eyes (+3.75D to -8.0D) with POAG and those of 88 high myopic eyes (8.25D to -28.0D) without POAG. Enlargement of the blind spot and minimal changes in the paracentral region were common findings in high myopic eyes without POAG. However defects in the peripheral portion of the visual field were rare in those eyes, so that such defects should be considered as glaucoma defects. The glaucomatous visual field defects were more progressive in higher myopic eyes. In high myopic eyes with glaucoma, it was not unusual that an extension of the visual field defects into fixation occurred at a relatively early stage.
