To guide patients and clinicians in the subject it would therefore be valuable to have a list of available products and their content. The purpose of this study was to investigate the ocular nutritional supplements available on the Scandinavian market and how their doses relate to current evidence. A list of nutritional supplements for ocular health available on the Scandinavian market was compiled by structured internet searches, and the products and their contents were compared with current evidence and legislated upper tolerable levels. Out of 104 products on the Scandinavian market, only two products reached the Age-Related Eye Disease Study 2 (AREDS2)-formula at the recommended dose. One additional product reached the same formula if the recommended dose was exceeded. As only two nutritional supplements for ocular health on the Scandinavian market reached the AREDS2-dose at recommended dose, clinicians offering such substances need to have knowledge not only about the substances but also of the doses. In the future it would be welcome if the health claims for nutritional supplements were based on placebo-controlled intervention studies, to avoid ineffective products.","PeriodicalId":222252,"journal":{"name":"Scandinavian Journal of Optometry and Visual Science","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121200817","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}

The aim of the study was to explore case finding of dry eye disease (DED) in optometric practice. A cross-sectional study examining dry eye symptoms and signs in 186 patients (18–70 years of age) attending a routine eye examination, with DED defined according to the criteria of the Tear Film and Ocular Surface Society Dry Eye Workshop II. Standard statistical tests were used, and clinical diagnostics were explored using sensitivity, specificity, and receiveroperating curve (ROC) statistics. Fifty-six patients were contact lens wearers, and they were significantly younger than the non-contact lens wearers (mean age 35 (SD = 1) versus 48 (± 2) years). The mean best corrected visual acuity (BCVA) in the better eye was 1.0 (± 0.1) (decimal acuity). There was no difference in BCVA between contact lens wearers and non-contact lens wearers. The mean Ocular Surface Disease Index (OSDI) score was 22 (± 19), and 138 patients had at least one positive homeostasis marker. Eighty-six had DED, 52 had signs without symptoms, and 23 had symptoms without signs of DED. The sensitivity and specificity of OSDI in detecting any positive homeostasis marker were 62% and 54%, respectively. In all, 106 patients had meibomian gland dysfunction (MGD), of which 49 were asymptomatic. In a ROC analysis, an OSDI ≥ 13 showed a diagnostic ability to differentiate between patients with a fluorescein breakup time (FBUT) < 10 seconds and a fluorescein breakup time ≥ 10 seconds, but not between patients with and without staining or MGD. The majority of patients had dry eye signs and/or dry eye symptoms. Routine assessment of FBUT and meibomian glands may enable case finding of DED in optometric practice.","PeriodicalId":222252,"journal":{"name":"Scandinavian Journal of Optometry and Visual Science","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115900190","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}

These symptoms have been linked to the use of digital devices. However, there is little knowledge related to this topic in adolescents, who spend increasingly more time using digital media. The aim of the study was to investigate eyestrain, headache, and musculoskeletal symptoms in relation to the use of tablets and smartphones in healthy adolescents with normal vision. Fifty healthy adolescents aged 11 – 13 years (mean = 12.1 (SD = 0.53)) with normal vision and development participated. A vision examination was performed by an authorised optometrist and an interview questionnaire measuring eyestrain, headache, and musculoskeletal symptoms in relation to screen use was filled out. In addition, screen time, ergonomics, participation in sports, and outdoor time were obtained. Forty-nine (98%) of the 50 children used a smartphone and 17 (34%) used a tablet. Overall, 12% to 41% experienced symptoms of headache, neck pain, tiredness and/or tired eyes while using smartphones and tablets. Nine (18%) experienced at least one symptom often or always while using their device. Musculoskeletal pain and headache were significantly associated with vision and eyestrain. Tablet use was associated with increased symptom scores compared to smartphone use. Increased screen time and shorter viewing distance were associated with eyestrain, headache, and neck pain. Children with neck- shoulder- and back pain were significantly (2.1 hours) less physically active than children without these symptoms. Most adolescents with good health and vision had no symptoms while using smartphones and tablets. However, a significant proportion still experienced symptoms of headache, neck pain, tiredness and tired eyes, and these symptoms were associated. Symptoms increased with screen time, shorter viewing distance and reduced participation in sports. This suggests that even healthy children with good vision may develop vision symptoms and musculoskeletal pain. Awareness should be raised among parents, teachers, eye care- and health care personnel, of the importance of good visual ergonomics and physical activity to promote health in adolescents.","PeriodicalId":222252,"journal":{"name":"Scandinavian Journal of Optometry and Visual Science","volume":"105 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122296653","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}

The purpose of this study was to quantify the frequency of vision anomalies, frequency of eye examinations, and use of corrective eye wear in adolescents in Norway, and to explore whether such vision anomalies affect reading test results or frequency of headaches. A cross-sectional study was performed in 436 adolescents (42.0% males) aged 16–19 years living in South-East Norway. Cycloplegic autorefraction, habitual stereoacuity, and habitual monocular amplitudes of accommodation were measured, and all participants reported the frequency of eye examinations, the use of spectacles and/or contact lens wear, and the frequency of headaches. Reading comprehension and decoding skills were evaluated for a subgroup of the participants (189 participants, 34.4% males) by their performance in national reading tests. Vision anomalies were defined as having refractive errors, poor habitual stereoacuity, or poor habitual amplitude of accommodation in at least one eye. Overall, 44.0% were classified as having a refractive error, and a total of 61.9% were measured to have vision anomalies. More frequent headaches were associated with poor habitual amplitude of accommodation when adjusted for sex (p = 0.04). The frequency of poor reading comprehension was higher in the group of adolescents with vision anomalies (n = 109, 31.2%) compared with those with no vision anomalies (n = 80, 18.8%; p = 0.05). Of those with vision anomalies, 33.5% had never had an eye examination, and 63.9% reported not wearing a correction. In Norway, there is no mandatory vision screening after 4 years of age. The results here show that a nation-wide programme of regular eye examinations and proper treatment of vision anomalies for all children and adolescents in Norway should be considered. Identifying and treating children with common eye problems in primary and secondary school will improve educational attainment and increase each child’s chances of succeeding in further education.","PeriodicalId":222252,"journal":{"name":"Scandinavian Journal of Optometry and Visual Science","volume":"248 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131404976","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}

She had not experienced any visual symptoms, and no recurrent infections had occurred as far as she knew. She has a scotoma in her nasal visual field that her optometrist detected by a coincidence when she was in her twenties. The corresponding visual field defect is smaller and less deep than what may be expected from the structural appearance of the scar.
