However, minimal data are available in the literature on corneal characteristics in myopic Malay school children including the difference between the low myopic group and the moderate myopic group. Therefore, this study aims to determine the corneal characteristics of myopic Malay school children and their associations with axial length. Methods A total of eighty-four data samples were extracted from forty-two myopic Malay school children. Measurements of the central corneal thickness (CCT), corneal curvature, corneal diameter, and axial length were measured using Lenstar LS900, a non-contact optical biometer. Data were later stratified by the spherical equivalent refraction (SER) into a low myopic group and a moderate myopic group, and paired t-test were employed to determine the differences in the corneal characteristics between these two groups. Univariate and multivariate linear regressions were performed to identify factors that are significantly associated with axial length. Results There was no significant difference in the CCT, corneal curvature and corneal diameter between the low myopic group and the moderate myopic group (t82=0.015, P=0.99), (t82=−0.802, P=0.43) and (t82=−0.575, P=0.57), respectively. Pearson univariate correlation analysis found that axial length significantly correlated with corneal curvature (r=−0.765, P<0.001) and corneal diameter (r=0.614, P<0.001) but no significant correlation found with CCT (r=0.046, P=0.68). Multiple regression analysis showed that axial length was significantly associated with a flatter corneal curvature (P<0.001), older age (P<0.001) and larger corneal diameter (P=0.02). Conclusion This study reported the corneal characteristics in myopic Malay school children and its associations with axial length. Results of this study can serve as a reference value for the myopic Malay schoolchild population.","PeriodicalId":505255,"journal":{"name":"Clinical Optometry","volume":"30 1","pages":"107 - 114"},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140789954","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}

Methods: Her guardian consented to IRB-approved study outside typical FDA enrollment guidelines for CureSight dichoptic therapy. Acuity (EVA) and stereopsis was by PEDIG protocols. Results: A 6-year-old rural Alaska native girl in foster care had previously been diagnosed with anisometropic amblyopia and treated with spectacles and patching but had poor compliance with BCVA 0.9–1.0 logMAR. She demonstrated exceptional creativity and hyperactivity but had no other medical issues. Atropine was prescribed in addition to her spectacles +5.50+1.00x90 and +0.50+1.00x90, but the patient discovered the rare “Spectacle Flip” method that sabotaged therapeutic impact. She had EVA enrollment acuities of logMAR 0.9 right and −0.1 left with stereo 400 seconds of arc. After just one month dichoptic therapy 1.5 hours 6 days per week, acuity improved to logMAR 0.7 and −0.1 with stereo up to 140 second of arc. Four months later acuity was 0.6 right and −0.2 left. Stereoacuity improved from 400 to 200 arc seconds. Conclusion: Even when conventional compliance methods fail, dichoptic therapy with eye-tracking has the novel and unique potential to improve amblyopia treatment compliance with real-time monitored fixation compliance and confirmation of correct spectacle wear. Clinical Trial Registration: NCT06165705. Plain Language Summary: Dichoptic therapy with eye-tracking improved compliance and achieved de novo acuity and stereo gains in a girl with severe refractory anisometropic amblyopia compounded by the rare complication of topical atropine therapy called “spectacle-flip sabotage”","PeriodicalId":505255,"journal":{"name":"Clinical Optometry","volume":"114 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140089595","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}
