METHODS This retrospective observational case series involved reviewing clinical histories of patients with the onion sign. Imaging studies analyzed included spectral-domain optical coherence tomography, color and red-free photographs, near infrared reflectance, fundus autofluorescence, and blue-light fundus autofluorescence. RESULTS A total of 22 eyes of 20 patients with sub-RPE hyperreflective bands were identified. There were 15 women and 5 men with a mean patient age of 76 years (range, 60-92 years). Snellen best-corrected visual acuities ranged from 20/25 to counting fingers, with a median of 20/80. Two patients had bilateral involvement, and 3 of 17 eyes had multifocal onion signs in the same eye. All eyes had neovascular age-related macular degeneration, with type 1 (sub-RPE) neovascularization. In all patients, the onion sign correlated with areas of yellow-gray exudates seen clinically that appeared bright on red-free and near infrared reflectance imaging. No specific fundus autofluorescence or blue-light fundus autofluorescence pattern was identified. CONCLUSIONS The onion sign refers to layered hyperreflective bands in the sub-RPE space usually associated with chronic exudation from type 1 neovascularization in patients with age-related macular degeneration. With an associated bright near infrared reflectance, these bands may correspond to lipid, collagen, or fibrin. Because the onion sign colocalizes to areas of exudation that are known to consist of lipoprotein, we propose that this finding may represent layers of precipitated lipid in the sub-RPE space. To our knowledge, this is the first report of lipid detected in the sub-RPE space on clinical examination.</p>","PeriodicalId":8303,"journal":{"name":"Archives of ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1001/archophthalmol.2012.2491","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30834040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the widespread adoption of SD-OCT in diagnosing and monitoring retinal disease, ORT has become a more commonly recognized occurrence in eyes with focal disruptions of the outer retina related to multiple diagnoses. These structures appear to represent rearrangement of the photoreceptor layer in response to injury, in which surviving photoreceptors form new lateral connections with neighboring cells. Most commonly, ORT is observed in eyes with choroidal neovascularization due to diagnoses such as neovascular AMD, pseudoxanthoma elasticum, multifocal choroiditis, and central serous chorioretinopathy, but it has also been described in nonneovascular disorders such as AMD with geographic atrophy, retinal detachment, Bietti crystalline retinopathy, and retinitis pigmentosa. In eyes undergoing treatment with intravitreal anti–vascular endothelial growth factor, ORT is typically found in areas in which, prior to treatment, there had been substantial intraretinal fluid that presumably damaged the outer retinal architecture. This case illustrates the relative stability of ORT during a multiyear follow-up period. Eye-tracked and curved en face SD-OCT was helpful in documenting this stability. We have observed similar stability in many eyes with ORT, most commonly in eyes receiving long-term intravitreal anti–vascular endothelial growth factor therapy for neovascular AMD. As described previously, the volume of presumed fluid within the ORT structures may transiently fluctuate in response to intravitreal anti– vascular endothelial growth factor, but the number and distribution of the structures typically remain constant. This particular case illustrates a gradual but slow decrease in the size of the ORT structures, presumably due to progressive photoreceptor atrophy. The stability of ORT during years of follow-up further supports the concept that these structures themselves are not a sign of ongoing neovascular activity. Awareness of ORT is important so that its presence is not mistaken for a sign of leakage, potentially leading to unnecessary treatment.","PeriodicalId":8303,"journal":{"name":"Archives of ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1001/archophthalmol.2012.1802","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"31114961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
