To characterize structural changes of HCQ retinopathy with SD-OCT after drug cessation. Setting: Private practice and academic institution. Patient Population: Patients at New England Eye Center and Ophthalmic Consultants of Boston in Boston, MA diagnosed with HCQ retinopathy and followed after drug cessation. Chloroquine resistant malaria treatment in children Adverse reactions plaquenil Can plaquenil help with hot flashes SD-OCT is capable of detecting characteristic macular changes of HCQ toxicity. These typical macular abnormalities include loss of the parafoveal ellipsoid zone EZ, parafoveal thinning of the outer nuclear layer ONL and inner plexiform layer IPL, the “flying saucer” sign, and peripapillary nerve fiber layer thinning 12–14. Few. Aug 29, 2014 Several risk factors may increase the likelihood of retinal toxicity from Plaquenil such as, age of greater than 60 years, daily dose more than 6.5 mg/kg; use of the drug more than 5 years, obesity, preexisting retinal disease and, renal or liver failure. Because early toxicity changes can be revealed on SD-OCT, it is prudent to perform a baseline screening of patients taking Plaquenil. Multifocal ERG has the ability to detect early macular dysfunction, so it should be included as part of baseline screening. A maximum daily dose of Plaquenil of 5.0mg/kg real weight is recommended. Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Retrospective clinical data review by the Boston Image Reading Center.

How to Succeed in Plaquenil Screenings. Plaquenil-Induced Toxic Maculopathy - Decision-Maker PLUS. Bull’s Eye Retinopathy Early macular toxicity can cause stippling or mottling of the RPE Next, granular pigmentation and loss of the normal foveal reflex can occur It’s believed but not proven that if early macular changes are detected and the medication is stopped, any toxicity that has occurred can be reversed.1 If the maculopathy continues to progress, concentric zones of. Plaquenil-induced toxicity usually will not occur before five years of taking the drug. “Eye damage due to Plaquenil is not common,” he says. “Rarely will anybody who has good vision and minimal symptoms develop loss of central vision or ability to read if annual screening is done and visual are symptoms reported as soon as they occur so the medication can be stopped if toxicity occurs. Although the incidence of macular toxicity is infrequent with Plaquenil use at a dosage of 200mg or 400mg q.d. its visual impact can be devastating. 2,3 The associated classic retinal toxicity is described as a bull’s eye maculopathy ring of depigmented retinal pigment epithelium that spares the foveal area.
