Even if your eye pressure is normal, doctors will look for signs of Glaucoma, such as visual field loss, changes in the optic nerve, or some other changes.<\/p>\n\n\n\n<p>They may use various tests, including visual field tests to check for blind spots and imaging tests to examine the optic nerve. Doctors can also check blood flow to the optic nerve to detect any circulation-related issues.<\/p>\n\n\n\n<p>Also read: If you want to learn about these tests in detail, please refer to our article on <a href=\"https:\/\/wowrxpharmacy.com\/de\/blog\/eye-care\/glaucoma-test\/\">The Comprehensive Guide to the Glaucoma Test<\/a>.&nbsp;<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"normaltension-glaucoma-treatment\">Normal-Tension Glaucoma treatment<\/h2>\n\n\n<p>Managing NTG requires the same approach as treating Glaucoma. <a href=\"https:\/\/wowrxpharmacy.com\/de\/blog\/eye-care\/glaucoma-treatment\/\">Glaucoma Treatment<\/a> options typically include eye drops, laser therapy, or surgery to protect the optic nerve and lower eye pressure.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"eye-drops\">Augentropfen<\/h3>\n\n\n<p>Eye drops are often the <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC10458083\/#:~:text=IOP%2DDependent%20Therapies%3A%20The%20Drugs,hypotensive%20eye%20drops%20%5B68%5D.\" target=\"_blank\" rel=\"noopener\">first-line<\/a> treatment for NTG. These medications help lower eye pressure and protect the optic nerve. Common types of <a href=\"https:\/\/wowrxpharmacy.com\/de\/blog\/eye-care\/glaucoma-eye-drops\/\">eye drops for Glaucoma<\/a> include Prostaglandin analogs, which increase fluid drainage from the eye, and beta-blockers, which reduce fluid production. Using eye drops regularly as prescribed is essential for managing NTG and preventing further vision loss.<\/p>\n\n\n<div style=\"margin-top: 30px;margin-bottom: 30px;\" id=\"wowrx-1798547177\"><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"830\" height=\"266\" decoding=\"async\" src=\"https:\/\/wowrxpharmacy.com\/wp-content\/uploads\/C5-Banner.png\" aria-label=\"Releif your eye from Glaucoma with Careprost\" alt=\"Releif your eye from Glaucoma with Careprost\" class=\"wp-image-31857\"\/><\/figure><\/div>\n\n\n<h3 class=\"wp-block-heading\" id=\"surgery\">Operation<\/h3>\n\n\n<p>Surgery may be recommended by doctors if eye drops are ineffective in lowering eye pressure or if the condition worsens. Surgical options aim to create a new drainage pathway for fluid to exit the eye, helping to lower pressure. One common procedure is <a href=\"https:\/\/www.hopkinsmedicine.org\/health\/wellness-and-prevention\/trabeculectomy#:~:text=Trabeculectomy%20is%20a%20type%20of,glaucoma%20by%20lowering%20eye%20pressure.\" target=\"_blank\" rel=\"noopener\">Trabeculectomy<\/a>, where a small opening is made in the eye to facilitate fluid drainage. Surgery is only considered when other treatments have not provided sufficient control.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"laser-treatment\">Laser treatment<\/h3>\n\n\n<p>Laser treatment can also be an effective option for managing NTG. Procedures such as <a href=\"https:\/\/glaucoma.org\/treatment\/laser\/slt#:~:text=Selective%20Laser%20Trabeculoplasty%20(SLT)%20is%20a%20form%20of%20laser%20treatment%20that%20lowers%20the%20pressure%20and%20helps%20glaucoma%20patients%20by%20applying%20laser%20energy%20to%20the%20eye%E2%80%99s%20drainage%20tissue%2C%20starting%20a%20chemical%20and%20biological%20change%20in%20the%20tissue%20that%20can%20lead%20to%20better%20fluid%20drainage%20out%20of%20the%20eye.\" target=\"_blank\" rel=\"noopener\">Selective Laser Trabeculoplasty<\/a> (SLT) help improve fluid drainage by using a focused beam of light to target specific areas of the eye&#8217;s drainage system. This treatment is often less invasive than surgery and can be a good choice for patients who need additional pressure reduction alongside eye drops or when surgery is not an option. Regular follow-ups with doctors are crucial to monitor the effectiveness of laser treatment and ensure ongoing eye health.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"conclusion\">Abschluss<\/h2>\n\n\n<p>Normal-Tension Glaucoma (NTG) is a unique and often misunderstood eye condition that can silently threaten your vision. Unlike other forms of Glaucoma, NTG occurs with normal eye pressure, making it challenging to detect and diagnose. It has optic nerve damage and visual field loss, and it may not present noticeable symptoms until it&#8217;s in advanced stages.&nbsp;<\/p>\n\n\n\n<p>Regular eye check-ups and follow-ups are important for early detection of NTG. Treatment for NTG primarily focuses on lowering eye pressure through prescription eye drops, laser treatments, or, in some cases, surgery. With early detection and appropriate treatment, it\u2019s possible to protect your vision and maintain good eye health.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"frequently-asked-questions\">H\u00e4ufig gestellte Fragen<\/h2>\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list\">\n<div id=\"faq-question-1722584720522\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">What is the cause of Normal-Tension Glaucoma?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>The exact cause of NTG is not fully clear.

It typically becomes more prevalent as people get older, with a higher risk after age 40.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1722584725544\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">What is the best treatment for Normal-Tension Glaucoma?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>The primary treatment for NTG is to protect optic nerve damage and lower intraocular pressure. This is usually achieved through eye drops, laser therapy (such as selective laser trabeculoplasty), or surgery in some cases.\u00a0<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1722584726600\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">Who is at risk of NTG?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>Several factors increase the risk of NTG, including age, family history of Glaucoma, certain medical conditions like high blood pressure, and specific optic nerve characteristics.
