    Plaquenil and thinning outer nuclear layer of retina

    Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine. In the United States, hydroxychloroquine is most often used for its anti-inflammatory effects in rheumatology and dermatology.

    The choroidal vasculature supplies the outer one-third of the inner nuclear layer, outer plexiform layer, outer nuclear layer, photoreceptors, and RPE. Because of this division of the blood supply to the retina, ischemic choroidal vascular lesions and ischemic lesions attributed to the retinal vasculature produce different histologic pictures. Parafoveal thinning of the outer nuclear layer follows, before retinal pigment epithelium damage is visible. Careful screening with multiple tests can detect toxic damage before prominent loss of the outer nuclear layer. The outer nuclear layer is thinner in eyes with pachychoroid pigment epitheliopathy than eyes with uncomplicated pachychoroid and eyes of healthy subjects. The degenerative process of pachychoroid spectrum diseases may begin with retinal pigment epithelium alterations before subretinal fluid accumulation.

    While early toxicity may be asymtomatic, patients with more advanced stage of toxicity may complain of color vision changes or paracentral scotomas. Its toxic effects on the retina are seen in the macula.

  7. Along with it comes thinning of the outer nuclear layer ONL, which is where the cell bodies of the photoreceptor cells reside. Vision loss from RP can also come from CME cystoid macular edema which is something to keep in mind for your RP patients. You can treat this with topical dorzolamide. Retinal detachment

    The outer nuclear layer or layer of outer granules or external nuclear layer, is one of the layers of the vertebrate retina, the light-detecting portion of the eye. Like the inner nuclear layer, the outer nuclear layer contains several strata of oval nuclear bodies; they are of two kinds, viz. rod and cone granules, so named on account of. Conclusion HCQ toxicity resulted in significant outer retinal layer volumetric thinning compared with controls. Quantitative assessment of outer retinal parameters and EZ mapping on SD-OCT may become a useful biomarker to identify and monitor HCQ toxicity. Aug 08, 2018 This relative thinning of outer retinas was caused by a thinning of two specific portions of the outer retina the outer nuclear layer ONL and ellipsoid zone EZ.
