An acute glaucoma attack can cause irreversible damage within a few hours if not treated urgently.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-453ce37f484017dac2790d6289e6b51c\" style=\"color:#71cc98;font-size:25px\"><strong><strong><strong><strong><strong>Alert! Symptoms of acute glaucoma<\/strong><\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p>Recognizing the symptoms of acute glaucoma is key to acting in time. The most common include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Intense eye pain, which may radiate to the head.<\/li>\n\n\n\n<li>Blurred vision or sudden vision loss.<\/li>\n\n\n\n<li>Perception of halos or flashes around lights.<\/li>\n\n\n\n<li>Redness of the affected eye.<\/li>\n\n\n\n<li>Nausea and vomiting, in some cases.<\/li>\n<\/ul>\n\n\n\n<p>These symptoms can be mistaken for a migraine or an eye infection, so it is essential to see an ophthalmologist if you suspect anything.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-35b6b2b5f521b8337afcd8a856712e14\" style=\"color:#71cc98;font-size:25px\"><strong><strong><strong><strong><strong><strong>Causes behind acute glaucoma<\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p>Acute glaucoma usually occurs when the drainage angle between the iris and the cornea closes, preventing the outflow of aqueous humor. This causes a rapid buildup of fluid inside the eye and a sudden increase in eye pressure.<\/p>\n\n\n\n<p>This phenomenon, known as angle closure, can be associated with:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Anatomical abnormalities in eyes with a narrow anterior chamber.<\/li>\n\n\n\n<li>Pupil dilation, for example, in dark environments or when using certain medications.<\/li>\n\n\n\n<li>Intense physical or emotional stress.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-1a773fc69fcac2d6b282420830d159ee\" style=\"color:#71cc98;font-size:25px\"><strong><strong><strong><strong><strong><strong>Risk factors for acute glaucoma<\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p>Although anyone can experience an acute glaucoma attack, certain factors increase the risk:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Age: From the age of 50, the likelihood of developing this type of glaucoma increases due to anatomical and functional changes in the eye associated with aging.<\/li>\n\n\n\n<li>Female sex: Women have a greater anatomical predisposition to a narrow angle, which raises the risk compared to men.<\/li>\n\n\n\n<li>Family history: Having first-degree relatives with glaucoma increases the risk of developing it.<\/li>\n\n\n\n<li>Hyperopia: Hyperopic eyes tend to be smaller, which contributes to a narrower angle between the iris and the cornea.<\/li>\n\n\n\n<li>Predisposing ocular anatomy: People with a narrower anterior chamber or reduced drainage angle have a higher risk of angle closure, especially in situations that cause pupil dilation.<\/li>\n\n\n\n<li>Use of medications: Certain drugs, such as anticholinergics or decongestants, can cause pupil dilation and trigger an acute attack in predisposed individuals.<\/li>\n<\/ul>\n\n\n\n<p>Identifying these factors during an eye exam allows for early intervention and prevention of complications.Detectar estos factores en una revisi\u00f3n oftalmol\u00f3gica permite anticiparse y prevenir complicaciones.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-008a9bad7c33765825ddd48ed2967be3\" style=\"color:#71cc98;font-size:25px\"><strong><strong><strong><strong><strong><strong>Urgent diagnosis of acute glaucoma<\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p>When acute glaucoma is suspected, diagnosis must be quick and accurate. The ophthalmologist will assess intraocular pressure, examine the condition of the optic nerve, and inspect the angle of the anterior chamber using techniques such as gonioscopy.<\/p>\n\n\n\n<p>Additional tests like tonometry or ocular scans may also be used to confirm the diagnosis and evaluate the extent of the damage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-e4e6f9690e2784f9ef04e6bb64fb50c3\" style=\"color:#71cc98;font-size:25px\"><strong><strong><strong><strong><strong><strong>Immediate treatment of acute glaucoma<\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p>The treatment of acute glaucoma must begin urgently to prevent permanent damage. In the initial phase, oral or intravenous medications are administered to rapidly reduce intraocular pressure.<\/p>\n\n\n\n<p>Once the condition is stabilized, the next step is to perform a laser iridotomy: a procedure that restores the flow of aqueous humor through a small opening made in the iris.<\/p>\n\n\n\n<p>In some cases, surgery may be necessary, especially if the angle remains closed or if there are other complications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-b1a69f1464eb089731981294cd9bff81\" style=\"color:#71cc98;font-size:25px\"><strong><strong><strong><strong><strong>Possible complications of acute glaucoma<\/strong><\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p>If not treated promptly, acute glaucoma can cause irreversible damage to the optic nerve and lead to severe vision loss or even blindness.<\/p>\n\n\n\n<p>In addition, repeated episodes can result in a chronic form of glaucoma, with progressive vision deterioration, even if the initial attack was brought under control.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2560\" height=\"1707\" src=\"https:\/\/miranza.es\/wp-content\/uploads\/2025\/06\/Glaucoma-2-scaled.jpg\" alt=\"\" class=\"wp-image-244435\" srcset=\"https:\/\/miranza.es\/wp-content\/uploads\/2025\/06\/Glaucoma-2-scaled.jpg 2560w, https:\/\/miranza.es\/wp-content\/uploads\/2025\/06\/Glaucoma-2-300x200.jpg 300w, https:\/\/miranza.es\/wp-content\/uploads\/2025\/06\/Glaucoma-2-1024x683.jpg 1024w, https:\/\/miranza.es\/wp-content\/uploads\/2025\/06\/Glaucoma-2-768x512.jpg 768w, https:\/\/miranza.es\/wp-content\/uploads\/2025\/06\/Glaucoma-2-1536x1024.jpg 1536w, https:\/\/miranza.es\/wp-content\/uploads\/2025\/06\/Glaucoma-2-2048x1365.jpg 2048w\" sizes=\"auto, (max-width: 2560px) 100vw, 2560px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-4774acb7ec155882ff6967724d5877aa\" style=\"color:#71cc98;font-size:25px\"><strong><strong><strong><strong><strong>Prevention and follow-up of acute glaucoma<\/strong><\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p>Preventing an acute glaucoma attack is possible by identifying risk factors and ensuring proper follow-up.
