Most credit Hermann von Helmholtz with the invention of the ophthalmoscope more than 150 years ago. Today, virtually all eye clinicians perform ophthalmoscopy on all patients. Hydroxychloroquine moa Hydroxychloroquine for leg cramps Hydroxychloroquine interstitial lung disease Plaquenil and alcohol consumption OCT imaging This test makes a detailed, three-dimensional image of your eye. Your ophthalmologist can use this image to look for early retinal damage. Multifocal ERG This test looks at cells in the retina called rods and cones. The test measures how well these cells respond to light. It can find retinal damage from Plaquenil. Hydroxychloroquine Maculopathy An Update on Screening and Diagnosis A brief guide for imaging SHIRI SHULMAN, MD. H ydroxychloroquine HCQ; Plaquenil, Sanofi, Bridgewater, NJ is an antimalarial agent that is also commonly used as a treatment for a variety of rheumatologic and dermatologic conditions, such as rheumatoid arthritis and systemic lupus erythematosus. 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. In contrast, OCT yields information about retinal anatomy and histopathology that is often entirely invisible to ophthalmoscopy. Nearly all forms of fundus photography, including ultra-widefield imaging, accurately capture what we view directly with the ophthalmoscope.

Following pupillary dilation with 1% tropicamide, hsUHR-OCT imaging was performed using a linear scan protocol with 8192 A-scans per image as previously described.7 All of the hsUHR-OCT images patients and controls were evaluated by 2 observers E.

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. The junction remains in the fovea white arrow. When this thinning is translated into an OCT map, a bulls-eye pattern of thinning is manifested, as shown in the image entitled "Time Domain OCT Map in Hydroxychloroquine Toxicity". The patient shown here is the same one shown in the image "Asymmetric Hydroxychloroquine Plaquenil Retinal Toxicity".
