The somatosensory system is capable of functional reorganization following peripheral denervation or training. Studies on human amputees with phantom limb pain provided evidence that these reorganizational changes are modulated through nociceptive input.
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
The phantom eye syndrome refers to phantom phenomena, such as phantom pain in the eye and visual hallucinations, after the removal of an eye (enucleation, evisceration).
