We investigated the changes in accommodative behaviour and binocular vision functions of Malay myopic children who participated in a myopia control trial utilising spectacle lenses (n = 40). This article presents baseline accommodation and binocular vision measurements. The mean (± SD) age, spherical equivalent measured by cycloplegic autorefraction, and axial length (AL) for the right eyes were 10.00 ± 1.47 years, -3.02 ± 1.20 D, and 24.42 ± 0.93 mm, respectively. All participants had good distance and near visual acuities with high-contrast charts (100%), which were significantly better than low-contrast charts (10%) (<i>p</i> < 0.001). The mean (± SD) accommodative lag at baseline was 1.14 ± 0.35 D, while monocular and binocular accommodative amplitudes were 15.35 ± 2.07 D and 16.82 ± 2.27 D, respectively. Malay schoolchildren in this study were more esophoric at near compared to distance, with an accommodative-convergence over accommodation (AC/A) ratio of 5.64 ± 0.66 ∆/D. A higher degree of myopia was found to be associated with a longer AL (<i>r</i> = -0.49, <i>p</i> < 0.05) and higher esophoria at near (<i>r</i> = -0.46, <i>p</i> < 0.05). These baseline measures are consistent with data from other studies showing that myopic children have a high accommodative lag, an elevated AC/A ratio, a longer AL, and are more esophoric at near. The measures reported herein will serve as a basis for examining changes that occur within 12 months of wearing myopia control spectacle lenses.</p>","PeriodicalId":43701,"journal":{"name":"Clinical Optometry","volume":"16 ","pages":"45-52"},"PeriodicalIF":1.7,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10893784/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139973864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even though remote eye exams are becoming increasingly frequent, comprehensive tele-eye care exams are still limited by the lack of published data. The aim of this study is to compare a comprehensive tele-eye care exam with a gold standard in-person primary eye care exam with an emphasis on refractive measurements, ocular health assessment, confidence level of the eye care providers and patient satisfaction. Methods: Sixty-six participants underwent two comprehensive eye exams performed by two eye care providers. One was a gold standard in-person exam, while the other was a remote exam performed by an eye care provider through videoconference. An overall patient satisfaction survey and a questionnaire for visual comfort with a trial frame from each modality were completed and the eye care providers scored their confidence level for each test. Exam results and diagnoses were compared between both modalities. Results: Tele-refraction has a good to excellent agreement with in-person subjective refraction in terms of sphero-cylindrical power and best corrected visual acuity. There was no statistically significant difference for visual comfort between both modalities. The agreement between in-person and remote exams for ocular health assessment ranged from fair to almost perfect, but there was a low prevalence of ocular pathologies within the study sample. The confidence level of the eye care providers and patient satisfaction were statistically higher in-person. Conclusion: Tele-eye care appears to be statistically and clinically non-inferior to in-person eye exams, especially for refraction, but the low prevalence of ocular pathologies somewhat limits the comparison of its efficacy for ocular health assessment. More studies on comprehensive tele-eye care exams are needed.","PeriodicalId":43701,"journal":{"name":"Clinical Optometry","volume":"8 9","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139394282","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}

This article focuses on the Medmont Meridia™, a state-of-the-art multipurpose diagnostic device with corneal topography and cutting-edge features. Corneal topography is pivotal in the early diagnosis of corneal disorders, determining baseline ocular surface assessment, helping in contact lens fitting, and monitoring ocular health over time. The Medmont Meridia boasts Placido-disc-based imaging with extensive corneal coverage. Furthermore, the Meridia accurately measures the horizontal visible iris diameter, pupil diameter, and palpebral fissure width, which assists in making contact lens parameter decisions. Additionally, it offers sagittal height data for scleral lens design and first lens selection, streamlining the fitting process. Beyond its topography capabilities, the Meridia excels as a comprehensive dry eye assessment tool. With features like tear meniscus height, tear film surface quality, and meibography capabilities, it aids in diagnosing dry eye and monitoring its progression. The device also provides customizable dry eye reports with integrated grading scales and questionnaires, making dry eye management, patient education, and compliance more accessible. In conclusion, the Medmont Meridia consolidates a multitude of examination tools in a single instrument, enhancing practice efficiency and elevating patient care and communication.
