    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.

    Hydroxychloroquine Plaquenil and chloroquine cause ocular toxicity to various parts of the eye such as the cornea, ciliary body, and retina. Chloroquine can also induce cataract formation; however, no reports of hydroxychloroquine and cataract have been reported 1. 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. 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.

    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.

  4. The inner retinal layers are significantly thicker and hyperreflective from the acute infaract. After the initial acute phase of the retina artery occlusion, the swollen inner retinal layers will start to atrophy. OCT scans will display thin inner retinal layers with fairly normal outer retinal layers.

    Outer nuclear layer ONL thinning was present in 100 % and observed as a focal indentation in the parafoveal ONL when compared to peripheral ONL thickness. Disruption of the parafoveal interdigitation zone IZ was recorded in 88 % and reduced reflectivity of the parafoveal EZ band in the absence of definitive disruption was observed in 50 %. Spectral-domain optical coherence tomography demonstrating advanced hydroxychloroquine retinopathy with parafoveal loss of the external limiting membrane, disruption of the outer ellipsoid zone, thinning of the outer nuclear layer and disruption to the underlying retinal pigment epithelial layer A. 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.

    The experts suggested the drug be included in the next version of the treatment guidelines and applied in wider clinical trials as soon as possible, Sun Yanrong, deputy head of the China National Center for Biotechnology Development under the Ministry of Science and Technology (MOST), said at a press conference.

    Rheumatoid Arthritis Treatment Options Johns Hopkins. Rheumatoid arthritis is a chronic disorder for which there is no known cure. Fortunately in the last few years, a shift in strategy toward the earlier institution of disease modifying drugs and the availability of new classes of medications have greatly improved the outcomes that can be expected by most patients.

    Chloroquine drug Britannica Chloroquine is administered orally as chloroquine phosphate. It also can be given by intramuscular injection as chloroquine hydrochloride. Chloroquine is effective against susceptible strains of the malarial parasites Plasmodium vivax, P. ovale, and P. falciparum, as well as certain parasitic worms and amoebas.
