### Patient: Doctor, I've been experiencing knee cramps or spasms lately and my eyes are burning and itching. I'm also seeing double.
### Doctor: Based on your symptoms, you might have chorioretinitis. It is an inflammation of the retina and choroid which can cause double vision and burning or stinging of the eyes. The knee cramps or spasms may be unrelated to the condition. We'll need to do some further tests to confirm the diagnosis.
