After my 4th TCH treatment I started having problems with my right eye. My vision would get very blurry and I would see "ghosts" of everything - worse at night. I have needed glasses for some time now, but this was sudden and severe. Even wearing my glasses I couldnt' read or see distance well enough to drive at night. Then, after two days it cleared up and i was back to my regular vision. It has happened four or five times since then (over about 7 months). They thought it was chemo related, but I finished chemo on 5/30 and it is still happening about once a month. I have had repeated eye exams by an opthomologist and no one can find a reason. No one mentioned it as a possible side effect of Herceptin. I hope it is - if so, maybe it will quit once I finish Herceptin in 2/08. Keep us posted. I would love to hear whatever you find out.
