A 15-year-old man presents to the Emergency Department (ED) complaining of blurred vision in the right eye, floaters, and mild headache.
He is otherwise well and has normal vital signs. Systems review is unremarkable, and he has no past medical or ocular history, nor immunosuppression. He is up to date with all his childhood immunisations and reports no other symptoms/ injuries.
Cranial nerve exam is normal, and there is no focal neurological deficit. On slit lamp examination there is some mild vitreous inflammation, as well as raised intraocular pressure. Fundoscopy reveals focal retinitis, with a pigmented retinal scar. You are about to request further investigations, when he tells you that he has been spending a lot of time with his pet cat recently, as he is going away on a family holiday soon.

That’s really a good one.
Interesting but useful rarity. Had to be toxoplasma once the cat was mentioned; everyone who was around in the 90s saw Trainspotting.
