I wish there was an easy answer to "is this part of Lupus" but since Lupus can attack any part of the body almost anything can be a part of Lupus. My first question to you is... Are you on Plaquinil? If so then you need to go have a plaquinil eye exam at an ophthalmologist. Many of us have eye issues but you need to rule out the plaquinil causing it before anything else.
Hope this helps!
