A 7-month-old DSH cat is presented with a 2-month history of waxing and waning inappetence, lethargy, and some weight loss. The owner has noticed that both of the eyes look abnormal.
| Question | Answer | Article | |
| What abnormalities are visible? | There is obvious hyphaema (blood in the anterior chamber) which has clotted, suggesting a high fibrin content. The remaining view of the aqueous chamber is slightly hazy due to aqueous flare. The iris blood vessels are very prominent suggestive of an intense vasculitis. A focal deposit is visible on the anterior lens capsule and is likely to be a persistent pupillary membrane. The pupil has slightly irregular margins. |
