- The study examined the effectiveness of optical coherence tomography (OCT) for assessing iris pigmented lesions in cats, focusing on 18 cats with varying diagnoses including melanosis and feline diffuse iris melanoma (FDIM).
- OCT successfully measured iris thickness and computed the ratio of pigmented lesions to normal iris, showing that the ratio was significantly higher in early FDIM cases compared to those suspected of melanosis.
- The findings suggest that OCT can identify early-stage FDIM features, but more research is needed to confirm these results and assess the reliability of OCT in differentiating between iris melanosis and FDIM.
A 7.5-year-old intact male Japanese macaque was presented for evaluation of vision loss. After a complete ophthalmic examination, the patient was diagnosed with hypermature cataract in both eyes.
