Night blindness has passed into the medical literature as nyctalopia.<\/p>\n<p>The disease, known as <strong>chicken black<\/strong> among the people, can occur for many different reasons. However, it has been particularly characterized by retinitis pigmentosa.<\/p>\n<h3><strong>What Causes Night Blindness (Chicken Black)?<\/strong><\/h3>\n<p>Night blindness can be caused by a problem with the ability of the cells in the retina to see in dim light, or it can occur as a result of a vitamin deficiency or another eye defect. Problems in the rod-shaped cells in the retina layer of the eye that enable black and white vision are an important cause of night blindness.<\/p>\n<p><strong>Some of the factors that cause night blindness can be listed as follows:<\/strong><\/p>\n<ul>\n<li>\n<h4><strong>Age:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>As the person ages, the pupils may lose their ability to dilate and narrow somewhat. Insufficient dilation of the pupils in the dark or in dim light results in a decrease in the amount of light entering the eye. This causes night blindness. In addition, the transparency of the transparent layer called the cornea, which covers the surface of the eye, decreases with age. This negatively affects the contrast sensitivity of the eyes in the dark.<\/p>\n<ul>\n<li>\n<h4><strong>Presbyopia:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>Presbyopia is an eye defect that occurs with age. In this defect, there is a decrease in the eye&#8217;s ability to focus and adjust to light changes.<\/p>\n<ul>\n<li>\n<h4><strong>Myopia:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>Night vision may also be impaired in myopia with farsightedness.<\/p>\n<ul>\n<li>\n<h4><strong>Eye Blood Pressure (Glaucoma):<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>Eye pressure or glaucoma is an increase in intraocular pressure. In glaucoma, which affects peripheral vision, the vision problem becomes especially evident in the dark and while driving.<\/p>\n<ul>\n<li>\n<h4><strong>Some Drugs Used in Eye Blood Pressure:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>Eye pressure medications that constrict the pupils can cause a decrease in the amount of light entering the eye, resulting in impaired night vision.<\/p>\n<ul>\n<li>\n<h4><strong>Cataract:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>Cataract is a condition in which vision becomes blurred due to a decrease in the transparency of the lens of the eye inside the eye. Cataracts cause difficulty in driving, especially when driving at night, as the headlights of oncoming vehicles cause discomfort to the eyes.<\/p>\n<ul>\n<li>\n<h4><strong>Diabetic Retinopathy:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>Diabetic retinopathy, a condition caused by the damage of diabetes to the retina layer at the back of the eye, can cause serious vision loss. The Diabetic retinopathy, one of the leading causes of retinal blindness in adults aged 20 to 64 years, can develop permanent and total blindness if left untreated.<\/p>\n<ul>\n<li>\n<h4><strong>Retinitis Pigmentosa:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>A rare genetic disease in which dark pigment collects in the retina. This changes the way eyes respond to dim light. In the disease, retinal photoreceptor cells, namely rods that provide black and white vision and cone cells that provide color vision, begin to deteriorate. Therefore, there is no cure and eventually progresses to permanent blindness.<\/p>\n<ul>\n<li>\n<h4><strong>Vitamin A or Zinc Deficiency:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>Vitamin A and zinc deficiency can trigger night blindness. Although rare, not getting enough vitamin A in the diet can affect night vision. Since zinc helps the body absorb vitamin A, its deficiency can also cause night blindness. Night blindness caused by vitamin A or zinc deficiency causes symptoms that can be prevented or treated.<\/p>\n<ul>\n<li>\n<h4><strong>Keratoconus:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>The thinning and tapering of the cornea, the outermost layer of the eye, is called keratoconus. Keratoconus progresses over time, causing deterioration in night vision.<\/p>\n<ul>\n<li>\n<h4><strong>Exposure to The Sun:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>Sun exposure without proper eye protection can temporarily impair night vision.<\/p>\n<p>Night blindness, which is usually caused by the sun, resolves within two days. It is possible to prevent this situation by wearing sunglasses that protect against ultraviolet rays.<\/p>\n<ul>\n<li>\n<h4><strong>Complications Following LASIK Eye Surgery:<\/strong><\/h4>\n<\/li>\n<\/ul>\n<p>LASIK eye surgery is a method of correcting distance or near vision defects using laser. Although rare, patients who have had LASIK eye surgery may have impaired night vision after surgery. The most common complaint is glare or halos around lights at night.<\/p>\n<h3><strong>What are The Symptoms of Night Blindness (Chicken Black)?<\/strong><\/h3>\n<p><span class=\"diff--UX1Av\">When<\/span> night blindness <span class=\"diff--UX1Av\">i<\/span>s caused by hereditary retinitis pigmentosa, the symptoms and <span class=\"diff--UX1Av\">pro<\/span><span class=\"diff--UX1Av\">gr<\/span>e<span class=\"diff--UX1Av\">ssion<\/span> of the <span class=\"diff--UX1Av\">con<\/span>di<span class=\"diff--UX1Av\">tion<\/span> <span class=\"diff--UX1Av\">c<\/span>a<span class=\"diff--UX1Av\">n<\/span> vary <span class=\"diff--UX1Av\">signi<\/span>f<span class=\"diff--UX1Av\">ic<\/span>a<span class=\"diff--UX1Av\">n<\/span>t<span class=\"diff--UX1Av\">l<\/span><span class=\"diff--UX1Av\">y b<\/span>et<span class=\"diff--UX1Av\">ween<\/span> <span class=\"diff--UX1Av\">individuals due <\/span>to <span class=\"diff--UX1Av\">i<\/span>t<span class=\"diff--UX1Av\">s <\/span>in<span class=\"diff--UX1Av\">heri<\/span>t<span class=\"diff--UX1Av\">e<\/span><span class=\"diff--UX1Av\">d<\/span> n<span class=\"diff--UX1Av\">a<\/span><span class=\"diff--UX1Av\">tur<\/span>e<span class=\"diff--UX1Av\">.<\/span><\/p>\n<p><span class=\"diff--UX1Av\">Wh<\/span>i<span class=\"diff--UX1Av\">l<\/span>e night blindness<span class=\"diff--UX1Av\">,<\/span> <span class=\"diff--UX1Av\">also <\/span>kn<span class=\"diff--UX1Av\">own<\/span> <span class=\"diff--UX1Av\">as &#8220;chicken blindness,&#8221;

In addition, chicken black disease can cause problems in seeing different colors in some patients.<\/p>\n<h3><strong>Which Vitamin Deficiency Is Night Blindness (Chicken Black) Occur?<\/strong><\/h3>\n<p>Vitamin A deficiency can cause night blindness. Vitamin A, also known as retinol, is a molecule located in the light-sensitive area of \u200b\u200bthe retina and plays a role in turning nerve messages into pictures. In vitamin A deficiency, problems may occur in this transformation and night vision is affected.<\/p>\n<p>Diseases such as pancreatic insufficiency, cystic fibrosis; It may predispose to a deficiency of vitamin A, a fat-soluble type vitamin. Therefore, people with these diseases are also at risk for night blindness. Night blindness is a disease caused by vitamin deficiency. Getting enough vitamin A along with the diet is very important in preventing night blindness.<\/p>\n<h4><strong>Foods rich in vitamin A can be listed as follows:<\/strong><\/h4>\n<ul>\n<li>Carrot<\/li>\n<li>Melon<\/li>\n<li>Pumpkin<\/li>\n<li>Mango<\/li>\n<li>Spinach and other dark green leafy vegetables<\/li>\n<li>Liver-like red meat products<\/li>\n<li>Milk<\/li>\n<li>Egg<\/li>\n<\/ul>\n<h3><strong>How is Night Blindness (<a href=\"https:\/\/www.turkeyistanbulmedical.com\/\" target=\"_blank\" rel=\"noopener\">Chicken Black<\/a>) Diagnosed?<\/strong><\/h3>\n<p>Together with the general eye examination, if the retinal findings of the disease are established, we can diagnose the disease by performing a fundus examination.<\/p>\n<p>Here, we can list the three prominent findings as increased pigmentation in the retina, thinning of the vessels and pale vision in the optic nerve.<\/p>\n<p>In cases where these findings are not seen, other diagnostic methods are applied. In addition, the disease can be easily diagnosed by genetic analysis.<\/p>\n<h3><strong>How is The Night Blindness (Chicken Black) Test Performed?<\/strong><\/h3>\n<p>A straightforward and consistent field test has been designed to assess the dark adaptation time of the eyes.

It refers to the inability or difficulty to see clearly in low light or darkness, such as in a dimly lit room or while driving at night.<\/p>\n<p>Commonly referred to as &#8220;Chicken Black&#8221; (Tavuk Karas\u0131) in some cultures, it occurs when the &#8220;rods&#8221;\u2014the light-sensitive cells in your retina\u2014fail to function properly. While it doesn&#8217;t mean you are completely blind at night, it significantly impairs your visual transition from bright environments to dark ones.<\/p>\n<\/p><\/div>\n<\/details>\n<p>    <!-- Question 2 --><\/p>\n<details class=\"faq-item\">\n<summary>What are the main causes of Night Blindness?<\/summary>\n<div class=\"faq-content\">\n<p>Night blindness can be caused by various factors ranging from nutritional deficiencies to genetic conditions. <\/p>\n<h4><strong>The most common causes include:<\/strong><\/h4>\n<ul>\n<li><strong>Vitamin A Deficiency:<\/strong> One of the most common causes worldwide, as Vitamin A is essential for transforming light into nerve impulses in the retina.<\/li>\n<li><strong>Cataracts:<\/strong> Clouding of the eye&#8217;s lens makes it difficult to see in low light.<\/li>\n<li><strong>Glaucoma:<\/strong> Increased eye pressure can damage the optic nerve, affecting peripheral and night vision.<\/li>\n<li><strong>Retinitis Pigmentosa:<\/strong> A genetic disorder where dark pigment accumulates in the retina, creating &#8220;tunnel vision&#8221; and severe night blindness.<\/li>\n<li><strong>Usher Syndrome:<\/strong> A genetic condition that affects both hearing and vision.<\/li>\n<li><strong>Nearsightedness (Myopia):<\/strong> Severe nearsightedness can make night vision blurry.<\/li>\n<\/ul><\/div>\n<\/details>\n<p>    <!-- Question 3 --><\/p>\n<details class=\"faq-item\">\n<summary>Is Night Blindness curable or treatable?<\/summary>\n<div class=\"faq-content\">\n<p>The treatability of night blindness depends entirely on its cause. If the condition is <strong>acquired<\/strong>, it is often treatable. If it is <strong>genetic<\/strong>, management is the primary goal.<\/p>\n<ul>\n<li><strong>Treatable:<\/strong> If caused by cataracts, surgery can restore vision. If caused by Vitamin A deficiency, supplements and dietary changes usually resolve the issue. Nearsightedness can be corrected with a new prescription for glasses or contacts.<\/li>\n<li><strong>Manageable but not Curable:<\/strong> Genetic conditions like Retinitis Pigmentosa currently have no definitive cure, although low-vision aids and certain therapies may help slow the progression.<\/li>\n<\/ul><\/div>\n<\/details>\n<p>    <!-- Question 4 --><\/p>\n<details class=\"faq-item\">\n<summary>What are the early symptoms of Night Blindness?<\/summary>\n<div class=\"faq-content\">\n<p>Recognizing the signs early can help in diagnosing the underlying cause. <\/p>\n<h4><strong>Symptoms include:<\/strong><\/h4>\n<ul>\n<li>Excessive squinting or eye strain in low light.<\/li>\n<li>Difficulty navigating through a dark house, even with familiar surroundings.<\/li>\n<li>Significant delay in vision recovery after being blinded by oncoming headlights while driving.<\/li>\n<li>Trouble seeing stars on a clear night.<\/li>\n<li>Blurred vision when transitioning from a sunny outdoors to a dimly lit indoors.<\/li>\n<\/ul><\/div>\n<\/details>\n<p>    <!-- Question 5 --><\/p>\n<details class=\"faq-item\">\n<summary>Can you drive at night if you have Nyctalopia?<\/summary>\n<div class=\"faq-content\">\n<p>It is <strong>not recommended<\/strong> to drive at night if you suffer from significant night blindness. Nyctalopia reduces your ability to judge distances, see pedestrians, and react to sudden changes in the road environment.<\/p>\n<p>The glare from oncoming headlights can temporarily &#8220;wash out&#8221; your vision for several seconds, which is extremely dangerous at high speeds. If you suspect you have night blindness, you should consult an ophthalmologist for a comprehensive eye exam before getting behind the wheel after sunset.<\/p>\n<\/p><\/div>\n<\/details>\n<p>    <!-- Question 6 --><\/p>\n<details class=\"faq-item\">\n<summary>How is Night Blindness diagnosed by a doctor?<\/summary>\n<div class=\"faq-content\">\n<h4><strong>To diagnose the cause of your night vision issues, an eye specialist will perform several tests, including:<\/strong><\/h4>\n<ul>\n<li><strong>Phoropter Test:<\/strong> To check for nearsightedness or refractive errors.<\/li>\n<li><strong>Slit-lamp Exam:<\/strong> To look for cataracts or structural damage in the front of the eye.<\/li>\n<li><strong>Retinal Exam:<\/strong> To check for signs of Retinitis Pigmentosa or glaucoma.<\/li>\n<li><strong>Blood Tests:<\/strong> Specifically to measure Vitamin A and glucose (diabetes) levels.<\/li>\n<\/ul><\/div>\n<\/details>\n<\/div>\n<p>&nbsp;<\/p>\n","protected":false},"featured_media":9442,"template":"","blog_articles_category":[169],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v18.1 (Yoast SEO v18.4.1) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What is Night Blindness (Chicken Black)? - Plastic surgery in Istanbul<\/title>\n<meta name=\"description\" content=\"Night Blindness is a problem of reduced vision and visual acuity that occurs at night or in poor light conditions.
