Methods: The participants comprised of 30 age-matched normal eyes as controls (Group 1), 19 with early-AMD eyes (Group 2), 14 with intermediate-AMD eyes (Group 3) and 29 with advanced (neovascular) AMD eyes (Group 4). All subjects underwent routine ophthalmologic examination. The choroid images, which included the subfoveal choroidal thickness images, obtained using Spectral-Domain Optical Coherence Tomography (and the technique of Enhanced Depth ImagingEDI). All of the participants volunteered in this study and remained anonymous due to the protection of their personal data. Results: 92 eyes with age greater than 65 years old were included. The mean subfoveal choroidal thickness was 260.93 ± 46.54 μm in age-matched normal eyes, 255.10 ± 44.85 μm in early AMD eyes, 230.92 ± 45.70 μm in intermediate AMD eyes and 206.82 ± 44.43 μm in advanced (neovascular) AMD eyes. There were statistically significant differences in the measurement results Original Research Article Pateras and Kalogeropoulou; OR, 14(3): 6-17, 2021; Article no.OR.68428 7 between the 4th Group with the 1st Group (P<0.0001) and 2nd Group (P=0.0006) respectively, meaning that SFCT was greater in normal and early AMD eyes. Conclusion: Decreasing subfoveal choroidal thickness was demonstrated in the progression of AMD, especially in the advanced AMD eyes compared to normal or early AMD eyes.","PeriodicalId":51846,"journal":{"name":"4or-A Quarterly Journal of Operations Research","volume":"21 1","pages":"6-17"},"PeriodicalIF":2.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86944264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: It is a Prospective cross-sectional study of 94 patients diagnosed with SLE and Sjogren’s syndrome. All patients underwent: 1. History taking 1. Visual acuity assessment using standard illuminated Snellen chart 2. Slit lamp examination with dry eye tests 3. Fundus examination The findings were recorded in the proforma and subsequent analysis was done using SSPS software. Results: DED prevalence was 51.1% overall, 42% among SLE and 66.66%in Primary Sjogren’s syndrome. Severity of DED was noted to be more in Primary sjogren’swith 33.33% having severe DED. Conclusion: DED overall prevalence in connective tissue disorders is significant, highest being in Sjogren’s. The findings highlight the severity of DED in rheumatoid arthritisgreater to when compared with other connective tissue disorders.
