Here is a closer view of the retina, showing the haemorrhagic foci in more detail. What other tests would you do, more invasive than a simple blood count?
A bone marrow aspirate showed these nasty neoplastic cells, confirming the diagnosis of multiple myeloma. The dog has done well on cytotoxic drugs, although the internists have had quite a job to curtail his neoplastic disease without making him more myelosuppressed. As an ophthalmologist I’m more than happy to have flagged up his disease status by examining his retina and leave them to the tricky therapeutic decisions!
