    Hydroxychloroquine retinopathy was followed for 5 years to 8 years in patients off the drug for as long as 20 years. Ellipsoid zone length, autofluorescence images, and visual acuity stabilized in mild retinopathy. Severe retinopathy retinal pigment epithelial damage progressed steadily, much like retinal dystrophies. Is there really a scarcity in cases, though? New information shows that hydroxychloroquine retinal toxicity occurs 7.5 percent of the time, which is not that rare. 3. In those patients who are affected, their daily dose and duration of use varied widely. Chloroquine and hydroxychloroquine bind to melanin in the retinal pigment epithelium RPE and cause damage to the macular cones outside of the fovea. The drugs inhibit RPE lysosome activity, reduce phagocytosis of shed photoreceptor outer segments causing an accumulation of outer receptor segments.

    I have Chloroquine retinopathy deposits on the macula in both eyes after taking Hydroxychloroquine Sulphate for three and a half years for RA. I wasn't offered an eye test at the hospital before starting on this drug, but I was going to Boots Opticians to have an annual eye exam and digital retinal photo. Advanced hydroxychloroquine toxicity presents as a bullseye maculopathy. Since retinal toxicity is usually irreversible, early detection of retinal toxicity and cessation of the offending agent is the best treatment. Corneal toxicity presents as an intraepithelial deposition of the drug into the cornea, which rarely affects vision. Chloroquine has a very high volume of distribution, as it diffuses into the body's adipose tissue. Chloroquine and related quinines have been associated with cases of retinal toxicity, particularly when provided at higher doses for longer times. Accumulation of the drug may result in deposits that can lead to blurred vision and blindness.
