Plaquenil infection Hydroxychloroquine 200 mg tablet Synthesis of chloroquine Chloroquine quinine in a dt This study reports on abnormalities on optical coherence tomography OCT due to hydroxychloroquine HCQ toxicity using data from 10 patients with chronic retinopathy but normal Humphrey visual field testing. The OCT alterations included attenuation of the parafoveal ellipsoid zone and loss of a clear continuous interdigitation zone. Dence of hydroxychloroquine maculopathy. Table.

Although hydroxychloroquine retinal toxicity is thought to be rare, recent studies suggest it may have a higher prevalence than previously recognized. A large study examining patients with more than 5 years of HCQ use were evaluated with 10-2 visual fields or spectral-domain optical coherence tomography SD OCT. Plaquenil (hydroxychloroquine) belongs to a group of medicines called quinolines. Please review the following URL and make sure that it is spelled correctly.

Plaquenil is used to treat or prevent malaria, a disease caused by parasites that enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia. Plaquenil Uses, Dosage & Side Effects -. Hydroxychloroquine Plaquenil Toxicity and Recommendations.. The optical coherence tomography angiography findings of.. Hence, it is imperative that we become familiar with recognizing the spectrum of HVF and SD-OCT findings associated with Plaquenil retinal toxicity. Of note, SD-OCT, in combination with Humphrey visual field testing, is critical for the early detection of Plaquenil retinal toxicity. Chloroquine and hydroxychloroquine belong to the quinolone family. They are related drugs with similar clinical indications for use and similar manifestations of retinal toxicity, although their therapeutic and toxic doses differ. Optical coherence tomography OCT is a noninvasive, transpupillary, retinal imaging technology, which uses near-infrared light to produce high-resolution cross-sectional images. It is suggested for diagnostic use as an alternative to standard excisional biopsy and to guide interventional procedures.
