Phantom eye syndrome: Its prevalence, phenomenology, and putative mechanisms

This study presents data on the clinical characteristics and possible mechanisms of the phantom eye syndrome in 112 patients after removal of one eye. The prevalence of phantom eye pain was 26%, nonpainful phantom sensations 29%, and visual hallucinations 31%. Headaches and preoperative eye pain were associated with the presence of phantom experiences. These results suggest that pain is an important cofactor for the development of phantom eye phenomena.
