Importantly, they also found that the drop shows no short-term structural effects on the eye, with only temporary changes in blood flow inside the retina.&nbsp;<\/p>\n\n\n\n<p>Ostrin\u2019s latest research is&nbsp;<a href=\"https:\/\/link.springer.com\/article\/10.1186\/s40662-026-00477-1\" target=\"_blank\" rel=\"noreferrer noopener\">published in the journal<\/a>&nbsp;<em>Eye and Vision<\/em>.&nbsp;It adds to a growing body of vision research from David Berntsen,&nbsp;Golden-Golden Professor of Optometry&nbsp;at the University of Houston,&nbsp;who is&nbsp;co-leading a&nbsp;<a href=\"https:\/\/www.uh.edu\/news-events\/stories\/2025\/september\/09182025-berntsen-atropine-drops-study.php\" target=\"_blank\" rel=\"noreferrer noopener\">national $25 million NIH-funded clinical&nbsp;trial<\/a>&nbsp;to delay the development of myopia in children by using the atropine drops.&nbsp;<\/p>\n\n\n\n<p>Low concentration atropine is widely prescribed to slow&nbsp;myopia&nbsp;progression in children, yet its short-term retinal and choroidal effects&nbsp;remain&nbsp;incompletely understood. Ostrin&#8217;s new study evaluated short-term effects of a range of low atropine concentrations on the length of the eye, the blood vessels in the retina and the thickness of the retina and choroid, which sits just behind the retina. These are important measurements because longer eye length is associated with myopia and as it gets longer, the retina and choroid are stretched.&nbsp;&nbsp;<\/p>\n\n\n\n<p>\u201cThese findings indicate that a single instillation of atropine does not alter axial length or retinal or choroidal thickness over 24 hours but may transiently affect superficial retinal perfusion in a time-dependent manner,\u201d said Ostrin.&nbsp;&nbsp;<\/p>\n\n\n\n<p>In the double-masked, randomized study, twenty healthy adults received a single instillation of either a placebo or atropine in the right eye during five separate sessions. Researchers then checked the eye structure, thickness, and length in the central retina both one-hour and 24-hours later.&nbsp;&nbsp;<\/p>\n\n\n\n<p>\u201cCharacterizing these short-term effects is important for a better understanding of the physiological responses to atropine in clinical and research settings,\u201d said Ostrin who previously&nbsp;<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/40492989\/\" target=\"_blank\" rel=\"noreferrer noopener\">published research<\/a>&nbsp;results of a study investigating the short-term effects of a range of low-dose atropine concentrations on the pupils of young adults. In that study, she found&nbsp;similar results&nbsp;with a single drop of atropine inducing significant changes in the pupils.&nbsp;<\/p>\n\n\n\n<p>Together, the studies&nbsp;indicate&nbsp;that atropine induces early functional and vascular effects in the eye, in the absence of structural change.&nbsp;&nbsp;<\/p>\n\n\n\n<p>\u201cBy linking objective ocular responses with subjective visual experience, this work advances our understanding of how atropine works and supports more precise, evidence-based, and individualized approaches to myopia management,\u201d said Ostrin.&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A single low-dose atropine eye drop can produce daylong effects in managing myopia, or nearsightedness.<\/p>\n","protected":false},"author":3,"featured_media":6737,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[526,1256,1483,800,19,20],"class_list":["post-11164","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-newsmakers","tag-eye-care","tag-eye-exams","tag-eye-injury","tag-eye-care-product","tag-health","tag-wellness"],"_links":{"self":[{"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/posts\/11164","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/comments?post=11164"}],"version-history":[{"count":1,"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/posts\/11164\/revisions"}],"predecessor-version":[{"id":11165,"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/posts\/11164\/revisions\/11165"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/media\/6737"}],"wp:attachment":[{"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/media?parent=11164"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/categories?post=11164"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/zestmag.com\/online\/wp-json\/wp\/v2\/tags?post=11164"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
