  • Abstract
  • Look Inside

A 49-year-old male presented with diplopia and hyperemia in his left eye. He had been involved in traffic accident 3 months before and had received decompression surgery for left optic canal fracture. We diagnosed him as traumatic carotid-cavernous sinus fistula. Laser speckle flowgraphy showed decreased circulation in the optic disc, the choroid and the retina. It also showed increased pulsation of retinal veins. Therapeutic embolization of the fistula was followed by improved intraocular circulation, decreased pulsation of retinal vein and improvements in visual acuity, visual field and critical fusion frequency. The findings suggest that the visual disturbance was associated with imparied intraocular circulation.
