A 65-year-old man suffered an injury to the right eye, caused by a stone which ricocheted while using a weed cutter in his garden at home. He had not been wearing eye protection. At initial assessment when he presented to the hospital 17 hours following the injury, his visual acuity was nil perception of light (NPL). He had a corneal perforation and early signs of endophthalmitis, including mucopurulent discharge and anterior uveitis, were already present. A CT scan showed no intraocular foreign body. Answer the questions and then compare them with how the team approached the situation. See article on page 44.
