It is commonly used for <strong>eye examinations<\/strong>, <strong>treatment of uveitis<\/strong>, and sometimes in <strong>myopia control in children<\/strong>. However, due to its pharmacological effects, there are specific situations where its use is contraindicated.<\/p>\n\n\n\n<p>The <strong>main contraindication<\/strong> is <strong>angle-closure glaucoma<\/strong>, also known as <strong>narrow-angle glaucoma<\/strong>. In this condition, the <strong>anterior chamber angle<\/strong> (the space between the cornea and the iris where aqueous humor drains) is <strong>already narrow<\/strong>. Atropine causes <strong>pupillary dilation (mydriasis)<\/strong>, which can <strong>push the iris forward<\/strong> and <strong>further narrow or completely close<\/strong> this angle. When the angle closes, <strong>intraocular pressure (IOP)<\/strong> rises dramatically, potentially causing <strong>sudden vision loss, eye pain, nausea, and headache<\/strong> \u2014 a medical emergency requiring immediate treatment.<\/p>\n\n\n\n<p>Using atropine in these patients can <strong>trigger an acute angle-closure glaucoma attack<\/strong>, which may lead to <strong>irreversible vision loss<\/strong> if not promptly managed. That\u2019s why <strong>screening patients for angle-closure risk<\/strong> (often with a slit-lamp or gonioscopy) before using mydriatics like atropine is critical.<\/p>\n\n\n\n<p>Other considerations for caution or relative contraindication include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hypersensitivity to atropine or its components<\/strong><\/li>\n\n\n\n<li><strong>Elderly patients<\/strong>, who are more susceptible to angle-closure<\/li>\n\n\n\n<li><strong>Very young children<\/strong>, where systemic absorption can lead to anticholinergic toxicity<\/li>\n<\/ul>\n\n\n\n<p>In summary, <strong>topical atropine should not be used in patients with angle-closure glaucoma or at high risk for it<\/strong>, as it can precipitate a dangerous rise in intraocular pressure and potential vision loss. Proper eye examination and patient history are vital before prescribing atropine.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>when is the use of topical atropine in the eye contraindicated?
