title: Modification by fluoangiography of color vision in diabetic patients.
abstract: Fluoangiography causes in diabetics a temporary increase of the number of errors when reading Birch and SPP II pseudoisochromatic plates, especially in case of macular edema and for tritan plates. Other experiments show that this change is more due to an increased filter effect by the fluorescein accumulation than to the increase of glare by the flashes for photography. Measurements of the foveal spectral increment threshold sensitivity curves does not show impairment of the blue mechanism by fluoangiography; on the contrary the green and red mechanisms become less sensitive.
