A "stroke in the eye" is not a medical diagnosis. It is a 'composite lay term" that might include: central or peripheral retinal vein or artery occlusion, arteritic or non-arteritic ischemic optic neuropathy, retinal artery emboli, even brain stroke with secondary peripheral visual field loss, idopathic or secondary optic neuritis. So you would need to post a precise diagnosis in order to offer helpful information. Best thing would be to get a second opinion from a university dept of ophthalmology or see a neuro-ophthalmologist.
