Central retinal artery acclusion following peribulbar anesthesia for pterygium excision

ME Gyasi, RA Kodjo, WM Amoaku


Pterygium is a common ocular surface pathology in tropical environments. In the early stages, it may be managed medically with topical anti-inflammatory
agents and ocular lubricants. However as the disease progresses, surgical excision becomes necessary and several anaesthetic methods may be used to assist this. We share our experience of a 30-year old woman who
underwent uneventful pterygium excision using peribulbar lignocain injection with adrenaline. She developed sudden blindness due to central retinal artery
occlusion with macular infarction. While peribulbar anaesthesia is generally safe, a remote risk of retinal vascular accident exists and its routine use should be done with caution. Where possible topical anaesthesia with or without intra-lesional injection be employed.
