Since Monday, I noticed that my vision was strange. I wrote it off as a headache, fatigue, or my imagination. Until this morning. I was in the kitchen trimming some chicken for homemade chicken noodle soup for lunch for the guys, and I realized that the chicken was blurry. Now, since an issue with a scopolamine patch (you can google the side effects regarding vision) post-surgery in 2006, I've worn reading glasses; however, I don't normally wear glasses to do anything else. This was weird. Then I realized that everything else around me was blurry. This evening, I asked Billy to Google the two medications I'm on for my migraines and cluster headaches (lithium and Topamax). BINGO!

IMPORTANT DRUG WARNING
Dear Healthcare Professional:
We have updated the prescribing information for TOPAMAX® to provide new information about an ocular syndrome that has occurred in patients receiving topiramate. This syndrome is characterized by acute myopia and secondary angle closure glaucoma. This information is based on postmarketing experience in more than 825,000 patients.
As of August 17, 2001 there have been 23 reported cases: 22 in adults and 1 in pediatric patients. It is generally recognized that postmarketing data are subject to substantial under-reporting.
Symptoms have typically occurred within the first month of therapy, with patients reporting an acute onset of decreased visual acuity and/or ocular pain. Eye examination revealed myopia, redness, shallowing of the anterior chamber and elevated ocular pressure, with or without pupil dilatation. Supraciliary effusion may displace the lens and iris anteriorly, secondarily causing angle closure glaucoma.
If patients develop this syndrome, the primary treatment to reverse symptoms is discontinuation of TOPAMAX as rapidly as possible, according to the judgment of the treating physician. Other measures, in conjunction with discontinuation of TOPAMAX, may be helpful.
The following has been added to the TOPAMAX prescribing information:
Under WARNINGS
Acute myopia and secondary angle closure glaucoma
A syndrome consisting of acute myopia associated with secondary angle closure glaucoma has been reported in patients receiving TOPAMAX. Symptoms include acute onset of decreased visual acuity and/or ocular pain. Ophthalmologic findings can include myopia, anterior chamber shallowing, ocular hyperemia (redness) and increased intraocular pressure. Mydriasis may or may not be present. This syndrome may be associated with supraciliary effusion resulting in anterior displacement of the lens and iris, with secondary angle closure glaucoma. Symptoms typically occur within 1 month of initiating TOPAMAX therapy. In contrast to primary narrow angle glaucoma, which is rare under 40 years of age, secondary angle closure glaucoma associated with topiramate has been reported in pediatric patients as well as adults. The primary treatment to reverse symptoms is discontinuation of TOPAMAX as rapidly as possible, according to the judgment of the treating physician. Other measures, in conjunction with discontinuation of TOPAMAX, may be helpful.
Elevated intraocular pressure of any etiology, if left untreated, can lead to serious sequelae including permanent vision loss.
Did you catch the part about 23 out of 825,000, and that was back in 2001? I'm playing the freaking lottery. I'm tired of being in the minority. Heck, just being a woman and getting cluster headaches, I'm beating the odds. I'm sure it must be a sign that I should play the lottery, right?

I've got to smile. I've already had the half hour of pure bawling from just being so over all this. I'm just so emotionally tired at this point. Tired of these headaches. Tired of feeling like crap. Tired of feeling like I'm totally useless to my family. I sure didn't need this.
From what I read, it seems like this should reverse itself once the medication is stopped. I sure hope so. If you read this and wanted to throw a prayer two my way, it wouldn't hurt my feelings.
I have a call in to the neurologist this morning. Of course, my incredibly wonderful neurologist is out of the office until Monday (and FWIW, my incredibly knowledgeable g.p. who prescribed oxygen for me prior to seeing the neurologist is off on Thursdays!), but his associate is in, and I left a message with the nurse, so hopefully, I'll hear something soon. I read you're not supposed to stop Topamax cold turkey. What they heck is THAT going to be like this weekend? LOL Oh, the joy of all this craziness. Thank you for letting me vent, my new friends. I'll let you know if we find out anything new.
Or if I win the lottery.
