{"title":"Vision care in concussion and traumatic brain injury: unmet needs.","authors":"Kenneth J Ciuffreda,&nbsp;Barry Tannen,&nbsp;Penelope S Suter","doi":"10.2217/cnc-2020-0009","DOIUrl":"https://doi.org/10.2217/cnc-2020-0009","url":null,"abstract":"The world of concussion and traumatic brain injury (TBI) entered a new dimension with the advent of the Iraq and Afghanistan wars, which have persisted over the past 2 decades [1]. This was later further echoed and amplified by the sports concussion ‘epidemic’ [1]. The effect of both occurrences drew much needed attention to the medical condition of concussion/TBI both diagnostically and therapeutically [1], with one emphasis being on the visual sequelae persisting in at least 20% of the patients [2]. Despite this renewed and on-going attention, at least two areas currently have unmet needs: acute concussion detection and clinical intervention for visual sequellae of severe TBI. The first area of unmet need – namely improved detection and diagnosis of acute concussion – is critical to prevent additional closely spaced, additive concussions [3], especially in our youths. Over the past decade or so, many subjective and objective diagnostic tests have been proposed [4,5]. A subjective test has been the King-Devick oculomotor-based test [6]. The King-Devick test has proven to be a sensitive, noninvasive test, with well-established normative data, which can be administered in the sports field and perhaps in the military theater. However, it is somewhat cumbersome to use, requires several minutes to explain, administer and score, relies heavily on having prior baseline testing done for pre/postcomparison and is best performed by either an experienced professional or a semi-experienced individual in a quiet setting. An objective test is dynamic pupillometry [7–10]. This approach is very rapid (taking about 5 s), noninvasive and easily administered in the sports field or military theater by relatively inexperienced personnel. Additionally, the quantitative results are immediate and have well-established normative data. Unfortunately, despite being a good potential vision biomarker for acute concussion [11] as well as other phases of TBI (e.g., subacute and chronic) [7–10], dynamic pupillometry has not been embraced by many. We suggest that dynamic pupillometry be the first line of diagnostic defense and, if the result is borderline, then the King-Devick test should also be used to improve diagnostic capability (i.e., specificity and sensitivity). Alternatively, both can be used if circumstances permit, which is optimal. The second area of unmet need is the wider, more aggressive use of simple, therapeutic visual interventions in the severe TBI population [12–14]. Vision care in this population remains a grossly underserved, orphan area. There are many reasons for this, with a likely primary one being the relative difficulty in interacting with this population in the presence of considerable physical, cognitive, attentional and/or language processing deficits, in addition to their constellation of visual dysfunctions. Although this group only accounts for approximately 20% of the overall TBI population [1], it is this subgroup for which the visual system ","PeriodicalId":37006,"journal":{"name":"Concussion","volume":"5 3","pages":"CNC77"},"PeriodicalIF":0.0,"publicationDate":"2020-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7506479/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38447375","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}
