  2. Parts of the Eye Parts of the Eye ● Anterior and Posterior Chambers ● Front Section (anterior segment) ○ Conjunctiva ○ Anterior chamber is between the cornea and the ○ Cornea ○ Iris iris ○ Posterior chamber is ○ Pupil between the iris and the lens ○ Ciliary body ○ Crystalline lens ○ Aqueous Humor

  3. Parts of the Eye Parts of the Eye ● Cornea ○ Conjunctiva ○ Front of the eye ■ Thin layer ○ Transparent ■ Protection ○ Rich supply of nerve fibers ○ Sensitive ○ Tears

  4. Cornea Parts of the Eye ● Iris ○ Heavily pigmented ○ Eye color ● Pupil ○ Hole ● Ciliary Body ○ Zonules ○ Increased pressure

  5. Iris and Pupil Parts of the Eye ● Crystalline Lens ○ Biconvex lens ○ Hardening ○ Cloudy

  6. Crystalline Lens Parts of the Eye ● Aqueous Humor ○ Viscous liquid ○ Prevents the eye from collapsing

  7. Parts of the Eye Parts of the Eye ● Vitreous Humor ● Back Section (posterior segment) ○ Jelly-like material ○ Vitreous Humor ○ Water, proteins, and ○ Choroid collagen ○ Sclera ○ Clumps - floaters ○ Optic Nerve ○ Retina ○ Macula ○ Central Retinal Artery ○ Central Retinal Vein

  8. Parts of the Eye Sclera and Choroid ● Choroid ○ Thin ○ Nourishment for the retina ● Sclera ○ “White of the eye” ○ Exterior and interior ○ Strong ○ Protection

  9. Optic Nerve and Retina Parts of the Eye ● Optic Nerve ○ Photoreceptors ○ Natural blind spot ● Retina ○ Thin multilayer tissue ○ Rods and Cones

  10. Parts of the Eye Parts of the Eye ● Macula ● Central retinal artery ○ Central part ○ Supplies the retina ○ Sensitive ● Central retinal vein ○ Heavy workload, retinal problems ○ Main blood vessel ○ Oxygen
