People with more serious viral or bacterial strains of this disease might experience eye discharge in the morning.Īnyone who has these warning signs should visit their doctor for a check-up to determine what’s causing this disease, if it is a virus or bacteria then conjunctivitis is quite contagious. Thankfully, most cases of conjunctivitis can be treated with rest, medication, and plenty of water. In addition to red eyes, conjunctivitis sufferers usually experience itchy eyes, increased tears, and eye pain. The main difference between conjunctivitis and Subconjunctival Hemorrhage is that with conjunctivitis, allergens, bacteria, or viruses are the cause of the blood vessel inflammation. Like subconjunctival hemorrhages, conjunctivitis adversely affects the blood vessels in the conjunctiva. To relieve eye discomfort associated with pingueculae, it’s a good idea to use re-wetting drops, place wet compresses over your eyes, and limit electronic screen time.Ī condition somewhat related to subconjunctival hemorrhage is known as conjunctivitis. In most cases, pingueculae are caused by prolonged exposure to UV rays and are more common after the age of 70. Therefore, it’s highly recommended anyone prone to developing these spots wear UV-blocking sunglasses whenever outdoors. While pingueculae may be irritating and unsightly, they aren’t normally a cause for concern. These degenerative nodules of the conjunctiva present as yellowish spots that are composed of hyaline and elastic tissue, and proteins and they tend to occur close to the nose.
Most likely your doctor will take a sample of your blood and check your liver function.Īnother common condition that causes yellow discolouration to appear in the sclera is pingueculae.

If you notice a yellow pigment starting to form on your eyes, then you should consult a medical professional ASAP. Another common reason for scleral icterus has to do with some forms of the hepatitis virus. Since bilirubin is produced mainly in the liver, it’s no surprise that people who develop scleral icterus often have liver issues. The most common reason people develop scleral icterus has to do with an increase of the yellowish chemical bilirubin in the bloodstream. Which is derived from the French word “jaune,” which means yellow. One of the more common scleral disorders is officially known as scleral icterus, but you’ve probably heard it referred to as “yellow eyes.” As the nickname suggests, this disorder causes the whites of your eyes to turn yellow.Ī common way to describe this yellowing of the eyes (and sometimes skin) is jaundice. Below, we’ll go over the more common scleral and conjunctival eye disorders. Most true scleral conditions aren’t household names, but there are a few worth mentioning. Interestingly, the more familiar conditions people assume affect the sclera actually affect the clear conjunctiva such as conjunctivitis. Since this layer is transparent, you can easily see signs of injury or stress appear on the conjunctiva as if they were on the sclera. Due to its toughness, the sclera is also of great help in protecting the eyes from damage due to direct trauma. Both of these thin and transparent tissues have many blood vessels of their own.Īs for the sclera’s functions, it’s really only designed to help the eyes maintain a healthy spherical shape. Indeed, the sclera gets most of its nutrients from two clear tissues above it known as the episclera and the conjunctiva.
Surprisingly, the sclera has almost no blood vessels of its own, which means it has to rely on nearby structures for nutrients. In some areas, the sclera has a thickness of about 1 mm, which makes it one of the thickest connective tissues in the eye. Scientists say the sclera is mostly made up of tiny fibers and a special protein called collagen. When you look in a mirror, the sclera encompasses all the area around your corneas and travels back to the optic nerve. You’ll also learn some of the more common diseases associated with this significant portion of the eyes.Īs mentioned above, the best way to describe the sclera is as the “whites” of the eyes. In this piece, we’ll explain exactly what the sclera is and how it supports healthy vision. Interestingly, a quick look at the colour of your sclera could tell you a lot about your overall health. While damage to the sclera usually won’t affect your vision, there are a few sclera conditions everyone should know about.

The full sclera wraps around the eye from the cornea all the way back to the optic nerve. Technically, the sclera that we see around the cornea is known as the anterior sclera and it only forms a portion of this incredible connective tissue. Sclera is a scientific term used to describe what most people call the “whites” of the eyes.
