Case ReportsColor Doppler image of central retinal artery of eyes with an intraconal mass.
Retinal ischemia secondary to hypoperfusion of the central retinal artery is recognized as one factor that may contribute to the development of loss of vision in eyes with intraorbital tumors. We study intraorbital tumors which produce motility disturbances and visual problems by color Doppler imaging to evaluate this factor. ⋯ Intraconal tumors could produce increased pressure in the optic nerve sheath and the optic nerve tissue which could be associated with impaired retinal and optic nerve blood flow and the subsequent amaurosis encountered with intraorbital tumors.
