What are scleras in cats? - briefly
The scleras in cats are the tough, white outer layers of their eyes that provide structural support and protection. Unlike humans, cats' scleras are often less visible due to their large irises and pupils.
What are scleras in cats? - in detail
The sclera in cats is the tough, fibrous outer layer of the eye that provides structural support and protection to the delicate internal components of the eyeball. Composed primarily of collagen and elastic fibers, the sclera maintains the eye’s shape and safeguards it from external damage. In cats, the sclera is typically white or off-white, though it is often less visible compared to humans due to the cat’s prominent iris and the positioning of their eyelids. The sclera extends from the cornea at the front of the eye to the optic nerve at the back, forming a continuous protective barrier. It also serves as an attachment point for the extraocular muscles, which control eye movement, enabling cats to track prey and navigate their environment with precision. While the sclera itself is not directly involved in vision, its integrity is essential for maintaining the eye’s overall health and functionality. In some cases, changes in the sclera’s appearance, such as discoloration or redness, can indicate underlying health issues, including inflammation, infection, or systemic diseases. Understanding the sclera’s role in feline ocular anatomy is crucial for recognizing potential eye problems and ensuring the well-being of cats.
