Poor Fresia the goat has developed this horrible eye. What do you see here, what would be your diagnostic plan and how might you treat what you find?
There is conjunctival thickening and hyperaemia, conjunctival and corneal ulceration, corneal oedema and a hypopyon. The differential list is probably endless so I’ll put you out of your misery and tell you that the goat has a conjunctival associated lymphoid tissue lymphoma. We exenterated the globe but the same tumour occurred in the fellow eye (as shown here) followed by a fatal asphyxiation from bronchial lymphoid tissue lymphoma – the mucosal lymphoid tissue lymphomas having homing receptors that take them to every mucosal site, so systemic therapy is a must.
