Conjunctiva vs. Cornea

By Jaxson

Main Difference

The main difference between Conjunctiva and Cornea is that the Conjunctiva is a Outer covering of sclera and Cornea is a part of the eye

  • Conjunctiva

    The conjunctiva lines the inside of the eyelids and covers the sclera (the white of the eye). It is composed of non-keratinized, stratified squamous epithelium with goblet cells, and also stratified columnar epithelium. The conjunctiva is highly vascularised, with many microvessels easily accessible for imaging studies.

  • Cornea

    The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea, with the anterior chamber and lens, refracts light, with the cornea accounting for approximately two-thirds of the eye’s total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. The cornea can be reshaped by surgical procedures such as LASIK.While the cornea contributes most of the eye’s focusing power, its focus is fixed. Accommodation (the refocusing of light to better view near objects) is accomplished by changing the geometry of the lens. Medical terms related to the cornea often start with the prefix “kerat-” from the Greek word κέρας, horn.

  • Conjunctiva (noun)

    A clear mucous membrane that lines the inner surface of the eyelid and the exposed surface of the eyeball or sclera.

  • Cornea (noun)

    The transparent layer making up the outermost front part of the eye, covering the iris, pupil, and anterior chamber.

  • Conjunctiva (noun)

    the mucous membrane that covers the front of the eye and lines the inside of the eyelids.
