Why is the sclera important?
The sclera is the main protective wall of the eye. Along with the cornea, it encloses the intraocular structures to protect them from injury and is important for maintaining the structure of the globe and the intraocular pressure.
What does the sclera protect?
The sclera, along with the intraocular pressure (IOP) of the eye, maintains the shape of the eyeball. The tough, fibrous nature of the sclera also protects the eye from serious damage — such as laceration or rupture — from external trauma.
Is white sclera good?
The white part of the eye that serves as a protective layer is called the sclera, which covers over 80% of the eyeball’s surface. A healthy sclera should be white. If it becomes yellow or discolored, an underlying condition may be present. Here are some reasons why your sclera might turn color.
Does the sclera protect the eye?
The sclera is tough and fibrous, protecting the interior components of the eye from injury, and makes up the exterior coating of the eye. The sclera forms the entire visible white exterior of the eye, while the iris is the colored portion inside the anterior chamber of the eye.
Is sclera all white?
The sclera, as separated from the cornea by the corneal limbus. In humans, and many other animals, the whole sclera is white, contrasting with the coloured iris, but in some other mammals the visible part of the sclera matches the colour of the iris, so the white part does not normally show.
Why do eyes turn white when blind?
A blind person may have no visible signs of any abnormalities when sitting in a chair and resting. However, when blindness is a result of infection of the cornea (the dome in front of the eye), the normally transparent cornea may become white or gray, making it difficult to view the colored part of the eye.
