We all know that with plaquenil comes annual (if not semi-annual) visits to the opthamologist. It seems that the use of plaquenil can cause (although it is rare) temporary pigment changes to the macula of the retina. It's my understanding (and my direct experience) that these changes are temporary...and that with discontinued use of the medication, the changes are reversible. I can't speak to the exact percentage of people on plaquenil whose eyes are affected, but despite the fact that it is very, very low...I'm one of the people that make up that percentage.
I started plaquenil shortly after I was diagnosed, and took it for about 4 years. I was on 400mg for the majority of the time, but was on a dosage of 600mg for a period of time. In fact, I was on that higher dosage when I was taken off of it due to the pigment changes that my opthamologist noted in my annual checkup. (In fact, when my rheumatologist increased my dosage to 600mg/day, my opthamologist increased my checkups to every six months. I might have even gone every three months for a spell!)
That said, my eyes return to normal, or so says my opthamologist (I couldn't tell any difference) after I discontinued the drug, and I stayed off of the drug for about 3 years, using Cellcept in its place. With both of my doctors' blessings, I opted to go back on plaquenil in order to get pregnant in 2007 - and have been on it ever since, with no problems at all.
So as of today, my eyes are hanging in there with plaquenil. But I don't want to get too far ahead of myself, because my opthamologist has just ordered two new tests, both of which are new to me.
The first, which I had last week, is called an OCT test, or an optical coherence tomography test. It actually scans the retina and allows my opthamologist to view both the retina and the macula (the small, sensitive area of the retina that gives central vision) in 3D to determine changes or alterations in the eye. Seems like it's all the rage in regard to eye exams these days...so glad my eyes and I could be so en vogue.
I was hopeful that this newfangled test (super common in testing for age-related macular degeneration, or AMD, but new to me) would be enough for this round of eye exams, but alas, it's not going to be that easy. (Never is when it comes to my eyes and lupus!) Turns out the eye assistant who ran the OCT test wasn't able to get a very crisp, clear picture of my eyes - my left eye in particular. Not sure why not - it's a question I have in to the doctor, but in any case, my doctor wants to step it up to another eye exam, called an ERG, or an electroretinography. I'll let you read about it here - it looks a little awkward to me, but as the literature says, I'll kick things off by "assuming a comfortable position."
Hmmm. I'll have to keep you posted on that one.
As always, feel free to chime in on this one. Always looking to hear from others who've been down this same road!
