[Visual field defects and fluorescein angiography in acute anterior ischemic optic neuropathy (author's transl)].

Typical visual field defects were found in 86 acute anterior ischemic optic neuropathies occurring in 71 patients. These field defects suggest a separate vascular supply of the upper and lower half of the disc and of the maculo-papillar bundle. A sub-division into four sectors can be inferred in the upper half of the disc. Fluorescein angiography showed sectorial differences of the capillary filling and leakage in some cases. This pattern was however poorly correlated with the localisation of the field defects.
