What is happening in this aged grey pony’s eye? The clue is in the ‘aged’ and the ‘grey’!
There is some dorsal corneal neovascularisation but also a darker arae underlying that in the iris. Its difficult to see on that picture and my photo-slit-lamp wasn’t playing ball, so here is an ultrasonogram showing the coropra nicra at the pupil margin nicely but also a mass more peripherally in the iris – an intraocular melanoma I’m sure. Not causing a problem so we’ll just leave it be I think!
