Treatments available for this disease rely mainly on copper chelators (D-Penicillamine and trientine salts) and zinc salts. 2014 Nov 4. (Dictionary of Eye Terminology, 3rd edition; Barbara Cassin, Sheila A.B. What is it? Furthermore, abnormal ocular motility may be observed even in the absence of abnormalities in brain MRI. (163 patients), KFR was detected in 66.3% of the patients and more frequently in those with neurological symptoms than those with hepatic symptoms (85.5% vs. 52.1%, p < 0.001) [25] (Table 1). Assoc. Li X., Ye T., Li Y., Zhang X. Moreover, the decoppering therapies could treat REM sleep behavior in patients with WD, reducing the copper overload in the subcoeruleus region responsible for REM [55]. Wilson Disease Association When the ring is not visible in subjects with WD, changes to the corneal microstructure are insignificant [26]. Exchangeable copper: A reflection of the neurological severity in Wilsons disease. On a color scale, it appears as a green/green-yellow/yellow/yellow-orange band. the contents by NLM or the National Institutes of Health. Other manifestations involving retinal and visual systems, eye mobility or other structures of the eye have been described with various frequencies. 2008 Jun;47(6):2089-111. 2007 Feb 3;369(9559):397-408. Review. Artificial intelligence for anterior segment diseases: Emerging applications in ophthalmology. Disclaimer. On the other hand, to assess the accuracy of IVCM in detecting KFR, Zhao et al. Anterior segment optical coherence tomography (AS-OCT) could be used for the detection of KFR. The incidence of KFR also varies according to the age of the diagnosis. 8600 Rockville Pike At presentation, the visual acuity was 6/24 and 6/18 in the right and left eye, respectively. See this image and copyright information in PMC. Careers, Unable to load your collection due to an error. 3 Department of Ophthalmology, Rothschild Foundation Hospital, 75019 Paris, France. Innes J.R., Strachan I.M., Triger D.R. The KFR appears on a grey scale as a hyper-reflective layer at the level of Descemets membrane in the peripheral cornea (Figure 3). From this review of the literature, it appears that ophthalmological involvement is frequent in WD patients, in particular for the KFR and, to a lesser extent, sunflower cataracts. Accessibility . Jang H.J., Kim J.M., Choi C.Y. New methods like AS-OCT and Scheimpflug imaging are alternatives to traditional SLE. In a study published by Kara et al., 22 patients with WD (mean age 29 years old) were compared to 22 age- and sex-matched controls [64]. Guillaud O, Dumortier J, Couchonnal-Bedoya E, Ruiz M. Diagnostics (Basel). Diagnosis and follow-up under decoppering treatment of these ocular findings are generally easily performed with slit-lamp examination (SLE). 2008;47:20892111. Nevertheless, no case series have been published yet to assert this association. Copper deposition in the lens leads to a sunflower or 'sunburst' cataractconsisting of a greenish central disc in the anterior capsule with spoke-like radial cortical opacities. and transmitted securely. Wilson's disease - Symptoms and causes - Mayo Clinic BCVA was reduced in the right eye (OD, hand motion) and normal VA in the left eye (OS). The child was managed with systemic D-penicillamine and a low-copper diet. Unlike SLE, these examinations are not operator-dependent, and the images can be sent to an experienced ophthalmologist improving the speed and sensitivity of the diagnosis. Wilson Disease Association is a Section 501(c)(3) nonprofit. KFR was observed at the periphery of the cornea as a hyper-reflective area, the extent of which was concordant with KFR severity on SLE. Slit lamp image of the right eye (A) diffuse illumination and (B) slit illumination showing greenbrown copper deposition at the level of DM (K-F ring) (highlighted by red arrows). compared 52 WD patients with KFR (mean age 24.8 years) with 52 healthy controls (mean age 25.0 years) [34]. Brownish-yellow ring visible around the corneo-scleral junction (limbus). Provenance and peer review: Not commissioned; externally peer reviewed. They suggest that video-oculography could be a sensitive electrophysiological marker of brainstem dysfunction in WD patients. Lancet. Wilsons disease in children with blindness: An atypical presentation. Negahban K., Chern K. Cataracts associated with systemic disorders and syndromes. AS-OCT and other techniques like RNFL measurement are easily accessible, even in an ophthalmology practice outside the hospital. Degirmenci C., Palamar M. Evaluation and grading of KayserFleischer ring in Wilson disease by Scheimpflug camera. Wilson's disease, also known as hepatolenticular degeneration, is an autosomal recessive genetic disorder of copper metabolism leading to copper accumulation in many tissues, mainly the liver, brain, cornea and kidney. Couchonnal E., Lion-Franois L., Guillaud O., Habes D., Debray D., Lamireau T., Brou P., Fabre A., Vanlemmens C., Sobesky R., et al. Ocular manifestations may be the first presenting symptoms of Wilsons disease which must be recognised to prevent fatal outcomes. rmeci A, Bayraktar , Ik AO, avu B, Akas R, stemihan Z, Sardal MK, Akyz F, Bek F, Kaymakolu S, zgi B, Demir K.

Wilsons Disease in Children: A Position Paper by the Hepatology Committee of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition. (Dictionary of Eye Terminology, 3rd edition; Barbara Cassin, Sheila A.B. Pediatr. You can have one faulty gene without having the disease. Sign of Wilson's disease. In the pediatric population, the cornea and the lens clarity were also impacted. confirmed that WD patients have a lower RNFL thickness than healthy controls [48]. An official website of the United States government. Nevertheless, it is puzzling that KFR is more frequent in neurological patients (like in adults) but more early in hepatic patients. Accessibility Sunflower cataracts usually do not impair vision, cannot be seen with the unaided eye or with an ophthalmoscope, and require slit-lamp evaluation for detection [23]. 2003 Jun;37(6):1475-92. Scheimpflug tomography and PHR were used to measure the changes in corneal and lens transparency. Accessibility It is a reversible sign and may disappear under treatment. However, new techniques are available for the precocious detection of ocular findings due to WD and may be of great value for non-experimented ophthalmologists and non-ophthalmologists practitioners. Symptoms are typically related to the brain and liver. -, Kelly C., Pericleous M. Wilson disease: More than meets the eye. The sunflower cataract in Wilsons disease: Pathognomonic sign or rare finding? It is usually bilateral [3] but a unilateral case was reported in 1986 [11]. sharing sensitive information, make sure youre on a federal official website and that any information you provide is encrypted Wilson's disease is a genetic disorder in which excess copper builds up in the body. Before Sunflower cataract is another classical ocular manifestation of WD, the frequency of which varies widely in the literature (between 2 and 20%) [10]. This research received no external funding. Bethesda, MD 20894, Web Policies The literature search was conducted systematically following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (http://www.prisma-statement.org, accessed on 1 February 2022). Moreover, we also describe new techniques used for their detection and follow-up. KayserFleischer ring; Wilsons disease; copper; eye involvement; sunflower cataract. Nevertheless, the utilization of those methods to assess therapeutic efficacy needs further evaluation. Rukunuzzaman M., Karim M.B., Rahman M.M., Islam M.S., Mazumder M.W. The ophthalmologic manifestations of Wilsons disease. Scheimpflug images of the posterior 60 m and anterior 120 m of the peripheral cornea were compared to SLE as a gold standard. ( A ): Retinal nerve fiber layer (RNFL) analysis, MeSH 2003 Aug;38(2):536. Nevertheless, the daily use of LSCM is still limited by its price on one hand, and the necessity of thorough training to interpret properly the imaging results on the other hand [32]. Am. Many ophthalmological manifestations have been described and new techniques are currently available to improve their diagnosis and to follow their evolution. Patients often have a low serum ceruloplasmin, low copper levels, increased urinary excretion of copper, and increased concentration of copper in the liver. In a study by Tribl et al., four patients with WD and REM sleep behavior disorder were described, three of which presented with REM sleep behavior disorder as the first initial symptom of the disease. In WD eyes, the corneal densitometry values were higher in the posterior total diameter (p < 0.037) and the total thickness of 1012 mm (p < 0.032), than in control eyes. Moreover, it is also useful in children and non-cooperative patients because the imaging process involves fixation for only a few seconds without exposure to bright light [36]. Ala A, Walker AP, Ashkan K, Dooley JS, Schilsky ML. Double Corneal Ring: Report of Simultaneous Coincidence of Kayser-Fleischer Ring and Fleischer Ring in a Keratoconus Patient Prior to Appearance of Wilsons Disease. Wiebers DO, Hollenhorst RW, Goldstein NP. 2023The Arizona Board of Regents on behalf ofThe University of Arizona. Wilson's Disease: Symptoms, Causes, Treatment, and Outlook - WebMD Nevertheless, the association between keratoconus and WD is not certain and could be a pure coincidence. Latency of visual evoked potentials (PEV) and electroretinography (ERG) were prolonged in WD patients MRI+ compared to WD patients MRI (p < 0.001 and p < 0.001, respectively). A case of glaucoma was reported in an 18-yo patient who presented with both forms (hepatic and neurologic form) of WD [61]. Characteristics of neurological Wilsons disease without KayserFleischer ring. 2020 Oct;237(10):1237-1239. doi: 10.1055/a-0898-3923. No significant difference was found in RNFL or CMT between WD patients MRI and controls. Some have a mask-like facies and pseudobulbar symptoms. A significant statistical correlation between the presence of KFR, and the clinical neurological manifestations, brain magnetic resonance imaging (MRI) or the toxic free copper (so-called exchangeable copper) was found in some studies [6,27]. Pentacam HR Scheimpflug imaging is a device that can provide three-dimensional image representations of the anterior segment, which may be useful for screening narrow angles. A systematic literature review was performed on PubMed to identify case reports and studies that treat WD and its eye involvement. Hepatobiliary malignancies are a significant risk, occurring in more than 1 percent of patients. A recent study performed by Langwinska-Wosko et al. The iris is the colored part of your eye. Since 2016, AS-OCT studies demonstrated a better Se and Sp to diagnose KFR compared to SLE. Erratum in: Hepatology. Imaging Kayser-Fleischer Ring in Wilson Disease Using In Vivo Confocal Microscopy. Kayser-Fleischer rings are dark rings that appear as circles around the irises of your eyes. Wilsons disease is rare. To the best of our knowledge, this is the first systematic recent review of the literature with regard to ophthalmological involvement in WD. Rapid eye movement (REM) sleep behavior disorder is also described in WD. Copper chelation therapy may cause fading and even disappearance of the corneal copper over time. official website and that any information you provide is encrypted Most people with Wilson's disease are diagnosed between the ages of 5 and 35, but it can affect younger and older people, as well. doi: 10.1055/s-2007-971173. These values were significantly correlated with the duration of the disease and the liver copper content (p = 0.012 for corneal densitometry and p = 0.018 for lens densitometry, respectively). Although copper accumulation begins at birth, symptoms of the disorder only appear later in life. Wilson disease (WD) is a rare inherited disorder in which an excessive amount of copper accumulates in the body. An Indian team has also shown prolonged latencies in PEV and ERG in WD patients with neurological manifestations compared to controls and the improvement of PEV and ERG latencies after treatment of WD [46].

Inclusion in an NLM database does not imply endorsement of, or agreement with, It consists of a ring-shaped copper deposit in the anterior chamber angle within the internal corneal layer of the Descemets membrane, at the Schwalbes line (Figure 2) [3,4]. The ocular manifestations of Wilsons disease include Kayser-Fleischer ring (K-F ring) and sunflower cataract. The disease consists of a continuous copper accumulation in many tissues and requires life-long treatment. EDS found consistent peaks for copper and sulfur in all of these electron-dense granules.

Other organs such as kidney, pancreas, heart and even joints may also be involved. They compared 58 WD patients mean age 38.7 years, with or without brain lesions on MRI (39 MRI+ and 19 MRI, respectively) and 30 healthy controls (mean age 39.6 years). Zinc and/or copper chelating agents such as D-penicillamine or trientine have long been used with benefit but the treatment must be used throughout life. In most .
