    Tamoxifen maculopathy


    Crystalline deposits and neurosensory retinal cavitary changes can develop in both tamoxifen retinopathy and nonproliferative idiopathic macular telangiectasia type 2 (Mac Tel2). Mac Tel2 is typically differentiated from tamoxifen retinopathy based on the presence of late leakage and mid-phase telangiectatic vessels on fluorescein angiography (FA) and the presence of hyperautofluorescence. Unlike Mac Tel2, tamoxifen retinopathy is known to be a progressive disease and the cessation of tamoxifen results in resolution of retinopathy. We report a unique case of nonproliferative Mac Tel2 in a 36-year-old Hispanic woman with tamoxifen use and the vision outcome 30 months after cessation of tamoxifen. The FA and optical coherence tomography angiography findings of this patient support the diagnosis of Mac Tel2, but her cessation of tamoxifen led to partial reversal of the topographic findings and improvement in visual acuity. This patient is also unique in the unusually young age of presentation for Mac Tel2. Karger AG, Basel Tamoxifen retinopathy usually manifests as crystalline maculopathy with or without cystoid macular edema (CME) [1, 2]. Our case supports that there are common pathways in the pathogenesis of tamoxifen retinopathy and Mac Tel2, and tamoxifen use could potentially accelerate foveal atrophy in patients with Mac Tel2. With the introduction of optical coherence tomography (OCT), structural changes in the fovea evidenced by loss of outer retinal layers or cavitation of inner retinal layers or outer retinal layers have been described [3-7]. Chloroquine and its derivative, hydroxychloroquine sulfate, which have been useful in treating malaria and in larger doses, collagen-vascular disease, cause a cumulative dose-related pigmentary retinopathy. Inhibition of critical enzymes & interference with the metabolic functions of retinal pigment epithelium (RPE) & photoreceptors. Both drugs apparently have a selective affinity for melanin, so it gets concentrated in RPE & uveal tissue & is retained for long periods, even after its usage is stopped. Accumulation of pigment laden cells in outer retinal layers 3. The earliest histopathologic change, even before RPE damage, appears to be membranous cytoplasmic bodies in ganglion cells and degenerative changes in photoreceptor outer segments. Damage & reduction of photoreceptors It increases with daily dose & duration & varies from 1-28% without any predilection for any particular age, sex or race. Symptoms: can be asymptomatic Earliest symptoms - difficulty in reading/ fine tasks due to central / paracentral scotomas Gradually these enlarge & involve fixation, reducing visual acuity later. Other symptoms- metamorphopsia, red-green haloes, cycloplegia, amblyopia, photophobia, flickering of yellow lights. Ocular signs cornea – vortex keratopathy - consists of grayish or golden brown corneal epithelial deposits.

Tamoxifen-induced ocular complications are very rare. A post-menopausal woman, diagnosed and treated case of carcinoma of left breast, on follow-up presented with history of gradual diminution of vision in both eyes of 3 months duration. Patient was on tamoxifen therapy 20 mg daily for the last 2 years. Fluorescein angiography, ocular coherence tomography confirmed the diagnosis.

It is an amphiphilic agent that can accumulate in lysosomes and cause oxidative damage. Unter Therapie mit Tamoxifen tritt bei 0,6–12% der behandelten Patienten eine Schädigung okulärer Strukturen auf. Diese zeichnet sich klassischerweise durch einen ausgeprägten Visusverlust bei kristallinen glitzernden Einlagerungen in die Makula mit Makulaödem oder durch kristalline Einlagerungen in die periphere Retina aus. Wir berichten über eine 55-jährige Patientin mit seit 10 Monaten bestehender Visusreduktion (OD und OS cc 0,2) bei Mammakarzinom und ossärer Metastase, die seit 7 Jahren eine Tamoxifentherapie (20 mg/Tag) erhielt. Funduskopisch bestand beidseits eine Papillenexkavation von 0,5 bei bekanntem primär chronischem Offenwinkelglaukom (PCOWG). In der optischen Kohärenztomographie (OCT) des rechten Auges zeigte sich ein zystoides Areal im Foveabereich mit fokaler lamellärer Disruption der Photorezeptorschicht ohne Anhalt für Makulaödem oder -verdickung. In der 30-II-Perimetrie des rechten Auges zeigte sich mit einer „mean deviation“ (MD) von 6,2 d B ein glaukomtypisches bogenförmiges Absolutskotom ohne Verbindung zum blinden Fleck. Das Gesichtsfeld des linken Auges war unauffällig (MD 1,1 d B).

    With the costs of medication rising, consumers are on the lookout for discounts on the drugs they need. PSM’s Timothy Mackey offered CNN some helpful tips on how to ensure the online pharmacy you are doing business with is a legitimate source of medication. From generic drugs to prescription drug coupons and prescription assistance programs,… [...] The internet is full of online pharmacy websites selling prescription medications at discounted prices, but most of those pharmacy websites are unlicensed, uncertified drug distributors. Food and Drug Administration does not recommend that people buy their drugs from Canadian pharmacies however, according to the Arizona Republic. [...] On October 13, a USA Today article featured a report released from the antivirus company Mc Afee. The medicines they sell are manufactured and sold outside government regulation, and because they’re unregulated, consumers who purchase them can never be sure what it is they are buying. [...] With the economic recession people have been looking for ways to save money and some have even resorted to visiting Mexican and Canadian pharmacies to buy prescription drugs. They found that 70 percent of spam in September was from websites advertizing “Canadian pharmaceuticals.” Further, the only thing that made it “Canadian” was the word Canadian and the maple leaves on the spammers’ web page. and the Drug Importation Debate – As the debate surrounding the possible ban on the repackaging of medicines in Europe simmers to a boil, here in the United States the potentially dangerous practice of ordering prescription medicines via the Internet is mushrooming. The increase in counterfeit drug spam may be due to the rising fears surrounding H1N1 flu, as well as the intensity around the topic of healthcare costs. Enticed by the promise of cheaper drugs and convenience by buying online, patients are largely unaware of the risks that come with online pharmacies. These risks can range from receiving products with too much, too little or no active ingredients, to being exposed to counterfeit products, which in some rare cases have been found to contain rat poison, boric acid and even inkjet cartridges! Nearly every day, there are new reports of counterfeit drugs flooding the world’s prescription drug market. VIPPS PharmacyChecker Blog Are All Canadian Pharmacies Rogue Online Pharmacies?
