Myopia and glaucoma.

2,528 visual fields of patients with glaucoma were examined. All atypical nerve fibre bundle defects (NFBD) were selected and all myopes. Myopic defects are a) enlargement of the blind spot, occurring in 18% to 30% of the myopic eyes depending in the degree of myopia, b) super-temporal refraction defect (2-6%) and c) irregular defects due to myopic choroidal dystrophy. Atypical NFBD were found in only a few non-myopes but in a large number of myopes. Temporal NFBD occurred in 16% and cecocentral NFBD in 9 to 18% of myopic glaucoma (MG). It is difficult to predict the existence of an atypical defect from optic disc evaluation.
