<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi Doctor, I have been experiencing redness and itchiness in my eyes for the past few days. I think I might have conjunctivitis.  <response>: I see. Based on your symptoms, I agree that you may have conjunctivitis due to bacteria. I will prescribe you with either Gentamicin Ophthalmic, Ciprofloxacin Ophthalmic, Tobramycin Ophthalmic, Erythromycin Ophthalmic, Dexamethasone-Tobramycin Ophthalmic or Bacitracin Ophthalmic, depending on the severity of your infection.
