[Visual field defect in eyes with branch retinal artery occlusion].

There have been few clinical studies that analyzed quantitatively the visual field defects observed in eyes with branch retinal artery occlusion. In the current report we retrospectively studied Humphrey static perimetric results in 7 eyes and Goldmann kinetic perimetric results in 8 eyes with branch retinal occlusion. All but one eye showed altitudinal-like field defects. The static perimetric results demonstrated large difference between sensitivities in each pair of upper and lower measured points adjacent to the horizontal line nasal to Mariott's scotoma, which indicated a steep slope between the defective field and the normal area. The defective field showed either absolute scotoma or sensitivity loss of 20 dB or larger.
