<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been having knee cramps or spasms and an itchiness in my eye. What could be wrong?  <response>: You might have Chorioretinitis, an inflammation in the eye that can cause itchiness or blurred vision, and it can also cause muscle spasms or cramps. I suggest you get an eye exam to confirm the diagnosis.
