An ocular examination can diagnosis uveal cysts. Cysts with a dense appearance may be mistaken for melanoma. Examination with a slit-lamp biomicroscope allows the cyst to be transilluminated so the veterinarian can determine that the cyst is hollow. Cysts can vary in size, shape, and number. Some patients need to have their eyes dilated to see the number, location and size of the cysts.
Laser coagulation can be used to remove particularly large cysts if necessary; otherwise, no treatment is needed. If glaucoma or melanoma is found, these diseases will require treatment.
