MLSHAPPL: Eye

• Eye


  Organ used for vision
• The Eyeball is composed of the three parts

  • Fibrous Tunic
  • Vascular Tunic
  • Nervous Tunic
• Sclera


  The "white of the eye" that surrounds the iris and pupil
• Choroid


  Brings oxygen and nutrients to the eye
• Retina


  Lines the back of the eye, contains light-sensitive cells that convert light into electrical signals which are then transmitted to the brain through optiv nerve
• Anterior Chamber


  • Provides nutrients to the cornea and lens
  • Maintains intraocular pressure
  • Helps refract light as it enters the eye
• Posterior Chamber

  • Supports the lens and maintains its shape
  • Contributes to the overall refractive power of the eye
• Vitreous Chamber


  • Provides structural support to the eye
  • Helps maintain the eye's shape
  • Transmits light to the retina
• Aqueous Chamber


  • Maintain Ocular pressure, having the same amount of fluid entering and leaving in the front of the eye
  • Influence in circadian cycle
  • Ensure that the eye remains inflated and maintains it shapes
• Vitreous Humor


  • A gel-like substance filling the inner chamber of the eye
  • Helps maintain the eye's shape and supports the retina
• Ciliary Body


  • Lens adjustment
  • Aqueous humor production
  • Eye function
• Zonular Fibers


  Lens movement by changing the eye's focus and accommodation
• Lens


  • A clear structure behind the iris
  • Further focuses light or images onto the retina
• Cornea


  • The clear outer layer of the eye, sitting on top of the iris and pupil
  • Helps focus light, producing a clear image on the retina
  • Acts as an additional protective layer for the eye
• Iris


  • The colored part of the eye
  • Regulates the amount of light entering the eye by adjusting the size of the pupil
• Pupil


  • Adjusts its size in response to changes in light
  • Constricts in bright light, dilates in dim light
• Ora Serrata


  Marks the junction between the posterior, photosensitive optic region of the retina and the non visual region
• Retinal Artery and Vein


  • Supplies the inner two-thirds of the retina
  • Returns blood from the retina to the heart
• Optic Nerve


  Carries information about what we see and transmitting it to the brain for it to interpret
• Macula Lutea


  Provide maximum visual acuity, central vision and color vision
• Fovea Centralis


  Responsible for enabling sharp visual details, such as recognizing face and reading
• Optic Disc


  Represents the beginning of the optic nerve and the point where the axons of retinal ganglion cells come together
• Eye Conditions

  • Cataract - Cloudy area in the lens of the eye, caused by aging
  • Glaucoma - A group of eye disease that can cause vision loss and blindness
• Pupil Conditions

  • Miosis - Constriction of the pupil
  • Mydriasis - Dilation of the pupil
