INTRODUCTION: The visual sensations many @entity1 experience during @entity231 surgery under local anaesthesia have received little attention until recently. This paper reviews the recent studies on this phenomenon, discusses its clinical significance and suggests novel approaches to reduce its negative impact on the surgery. METHODS: Literature review. RESULTS: Many @entity1 who have @entity231 surgery under retrobulbar, peribulbar or topical anaesthesia experience a @entity227 in their operated eye during surgery. These visual sensations include perception of light, movements, flashes, one or more colours, surgical instruments, the surgeon's hand/fingers, the surgeon and changes in light brightness. Some @entity1 experience transient no light perception, even if the operation is performed under topical anaesthesia. The clinical significance of this phenomenon lies in the fact that approximately 7.1% to 15.4% of @entity1 find their visual experience frightening. This fear and @entity148 may cause some @entity1 to become uncooperative during surgery and trigger a sympathetic surge, causing such undesirable effects as @entity101 , @entity591 , @entity6475 on the heart, @entity10441 and acute @entity4697 attack. Several approaches to reduce the negative impact of @entity1 ' visual experience are suggested, including appropriate preoperative counselling and reducing the ability of @entity1 to see during surgery. CONCLUSIONS: The findings that some @entity1 find their intraoperative visual experience distressing have a major impact on the way ophthalmologists manage their @entity231 @entity1 . To reduce its negative impact, surgeons should consider incorporating appropriate preoperative counselling on potential intraoperative visual experience when obtaining informed consent for surgery.
