I am a patient that had a successful surgery for a detached retina (rt eye) in 10/23/17. I ve had ongoing eye appointments since then, with successive eye drop (Keterolac, Brimonidine & Prednisolone) therapy. This weekend, I developed an infection in rt eye with large amount of pus in corner of rt eye. I have been taking benadryl (25 mg x 3), using ice without any result. As you can see, I m trying to avoid the ER or Ophthalamic appt. Can I try Tobramycin or Atropine Sulfate on this infected eye?
