“…In previous studies which assessed clinical tests of heterophoria measurement, the Maddox rod 17 was found to be the most reliable method and the modified Thorington 18 was considered the most repeatable. Red lens NPC is more sensitive in identifying convergence disorders.…”

Introduction: Alcohol ingestion has a significant effect on speech, vision and coordination. The legal limit for driving under the influence in South Africa is 0.05% blood alcohol concentration (BAC), whilst intoxication is considered to occur at 0.10% BAC. The aim of our study was to investigate the effect of acute alcohol ingestion of 0.05% and 0.10% blood respiratory alcohol concentration (BrAC) on heterophoria.Methodology: The effect of alcohol ingestion on the oculomotor systems of 31 subjects was the basis of this quasi-experimental quantitative study. Various parameters were compared before and after the ingestion of 10% alc red wine. The Alcoscan ALP-1 breathalyser test was used as an indicator of BrAC. Heterophoric, fusional vergence and near point of convergence (NPC) measurements were measured during an experimental phase at 0.05% and 0.10% BrAC levels and a control phase at a 0% BrAC.Results: Mean changes in heterophoria for distance showed an increase of 1.13∆ ± 1.34∆ and 2.19∆ ± 1.70∆ towards esophoria at a BrAC of 0.05% and 0.10% respectively. At near, the results showed a mean increase of 0.84∆ ± 1.75∆ and 0.97∆ ± 1.70∆ towards exophoria at a BrAC of 0.05% and 0.10% respectively. There was a further mean decrease in the positive and negative fusional vergences as well as receded NPC break and recovery measurements at 0.05% and 0.10% BAC.Conclusion: It can be concluded that a BrAC of 0.05% has a minimal effect on heterophoria. However, at a BrAC of 0.1% there is a significant effect on heterophoria, fusional vergences and the NPC. This may or may not be clinically significant.

“…While the Von Graefe method shows poor repeatability, clinical far phoria has a better repeatability than its, in principle more precise, laboratory counterpart. Earlier findings indicate that phoria is a particularly unstable oculomotor parameter.…”

Although different optometric tests of accommodation and vergence rely on the same basic principles, the results of this study indicate that clinical and laboratory methods actually involve distinct components. These differences, which are induced by methodological choices, must be taken into account, when comparing studies or when selecting a test to investigate a particular oculomotor component.

O uso exacerbado do sistema visual em sua sincinética, promove diversos distúrbios e sintomas no usuário de telas e excesso de atividades escolares, na atualidade. A preocupação com fatores estéticos do passado, em casos de estrabismo, atualmente são superadas por problemas de neurodesenvolvimento e aprendizagem, promovidos pelos excessos visuais. Observa-se na literatura, os malefícios do excesso de exposição à écrans e a astenopia digital. Desvios latentes são notados e podem provocar embaçamento da visão, fadiga da musculatura ocular, desinteresse e falta de concentração à leitura. A fadiga percebida nos músculos extrínsecos oculares é uma das responsáveis pelas forias, esses desvios provocam diversos efeitos neusosensoriais indesejados. As técnicas de aferição são diversas e com variações. Maddox, Torrington e Howell serão foco de discussão que terá como objetivo mensurar forias e sua compensação, evitando a sintomatologia. Através de revisão de estudos publicados e artigos, demonstra-se a importância da propedêutica e condutas optométricas frente a desvios.
