Tdrell...I have a follow up with eye doctor Tuesday morning. I will ask for an eye culture. She is convinced it’s an infection from the MAC. The red ring formation around the iris is textbook sign similar to Ocular TB infection. The steroids helped with pain and redness but I’m left with a strange white spot where the red ring was and a little pain left. She said to continue with ethambutol as she is pretty sure it’s not from the drug. Pulmonologist said to stop the Ethambutol but said the eye doctor would know more if I decide to continue with the medication. Frustrating...this whole experience seems to be a roller coaster ride of ups and downs.
