Similarities Between Sclera and Conjunctiva
- Sclera and conjunctiva are both components of the eye.
- Both structures serve as protective layers of the eye.
- Sclera and conjunctiva are vascularized tissues.
Difference Between Sclera And Conjunctiva
The human eye is a crucial body part consisting of several structures, including the iris, pupil, cornea, sclera, and conjunctiva. The conjunctiva and sclera are two essential components of the eye’s defense system. The conjunctiva is a thin layer of tissue that lines the eye and eyelids and helps maintain a balanced tear film while also providing protection against foreign objects and infections. The sclera, on the other hand, is a sturdy connective tissue composed of collagen and elastin that surrounds and gives the eye its shape. The sclera connects to the cornea at the front of the eye and joins with choroidal tissue at the back of the eye via the optic nerve. Maintaining the integrity of both the conjunctiva and sclera are vital for the overall health of the eye, as abnormalities or inflammation can lead to significant disruptions in the ocular system.
