Eye pain and homonymous hemianopia

Pain in the eye may be a symptom of a vascular accident in the parieto-occipital area of the brain and is associated with homonymous hemianopia. In five of our patients and in one patient described in the literature, the pain was localized on the side of the lesion, was not severe and was noticed only after the visual field defect had become apparent. Three of these patients had an associated defect of opticokinetic nystagmus. This referred pain is presumed to be mediated through the dural branches of the ophthalmic division of the trigeminal nerve.
