A Clinical Case from the Archives : 03/12/2006

This poor guinea pig always seems to have one eye somewhat closed. What might be the reasons for this?

Well lots of guinea pigs get hay awns in their conjunctival sacs as foreign bodies, or allergic or infectious conjunctivitis. But look at this eye in a bit more detail and see the dull lustreless cornea with deposits on its surface. The animal has dry eye and a Schirmer tear test of 0mm/min in this eye and 4mm/min in the other (a pretty normal level for these animals). We’re trying topical cyclosporine out which might seem a bit pricey but hopefully the pain relief will be worth it!
