I've been trying to get this shot for months, and finally succeeded!
If you're a regular here, you might remember that Benny sees an animal eye doctor twice per year. He has cataracts in both eyes and his right eye has glaucoma. The glaucoma has caused some interesting pigmentation in his eye that appear as brown areas. You can see it in his photo here. Click on the photo to biggify and get a better view.
The doctor has told us that sometimes, the pigmentation can be cancerous. Thankfully, the coloring has stabilized and doesn't seem to be a problem. The only "cure" would be to remove the eye, which we don't want to do unless there is no other choice.
He is due for another check up soon, and we'll update you on what the doc says.
