Uveitis

Cards (59)

  • What is the term for the middle vascular layer of the eye?
    Uvea
  • Name the three structures within the uvea.
    Choroid, ciliary body, and iris
  • What is the function of the optic nerve?
    It transmits visual information from the retina to the brain.
  • What transparent structure forms the outer most layer of the eye?
    Cornea
  • What are the three main layers of the eye and their general functions?
    • Sclera: Outer protective layer
    • Uvea: Middle vascular layer
    • Retina: Innermost sensory layer
  • Which layer of the eye contains the photoreceptors responsible for vision?
    Retina
  • What is the choroid responsible for in the eye?
    It provides blood supply to the retina.
  • What is the ciliary body responsible for?
    It produces aqueous humor and adjusts the lens shape for focus.
  • What is the function of the iris?
    It controls the size of the pupil to regulate light entry into the eye.
  • What is the cornea responsible for in the eye?
    It acts as a transparent protective barrier and refracts light into the eye.
  • How does the eye focus on objects at different distances?
    • The ciliary body adjusts the lens shape
    • Changing the lens curvature changes refractive power
    • This process is called accommodation
  • What is the pupil?
    The adjustable opening in the iris that controls the amount of light entering the eye.
  • What is the vitreous humor?
    A gel-like substance that fills the posterior cavity of the eye, maintaining its shape and supporting the retina.
  • What is the function of the lens?
    It focuses light rays onto the retina.
  • Which layer of the eye is the outermost tough white protective layer?
    Sclera
  • What is uveitis?

    Inflammation of the uvea in the eye
  • What parts make up the uvea?
    The iris, ciliary body, and choroid
  • How is uveitis classified based on the affected parts of the eye?
    By anterior, intermediate, and posterior uveitis
  • What are the symptoms of anterior uveitis?
    Pain and red eyes
  • What does intermediate uveitis affect?
    The vitreous and retina
  • What can posterior uveitis potentially cause?
    Visual loss
  • What are common causes of uveitis?
    Autoimmune diseases and infections
  • What can severe cases of uveitis lead to?
    Vision impairment
  • What is the role of the ciliary body?
    Produces fluid and changes lens shape
  • What is a common symptom of uveitis?
    Eye pain
  • How is uveitis diagnosed?
    Through a comprehensive eye examination
  • What is a slit-lamp examination used for?
    To view the eye's structures
  • What is the purpose of corticosteroid eye drops in uveitis treatment?
    To reduce inflammation
  • What can untreated uveitis lead to?
    Serious complications
  • What is panuveitis?

    Inflammation across all three parts of the uvea
  • How do autoimmune diseases contribute to uveitis?
    They cause the immune system to attack the uvea
  • What are floaters in relation to uveitis?
    Spots in vision caused by vitreous inflammation
  • What is the function of the choroid?
    Provides oxygen and nutrients to the retina
  • Why is early detection of uveitis important?
    To prevent serious complications
  • How does the treatment for uveitis vary based on its cause?
    It may include corticosteroids or antibiotics
  • What is photophobia?

    Sensitivity to light
  • What is the role of regular eye exams in uveitis?
    For early detection and treatment
  • What are the types of uveitis and their characteristics?
    • Anterior uveitis: Affects iris and ciliary body; symptoms include pain and redness.
    • Intermediate uveitis: Affects vitreous and retina; symptoms include blurred vision and floaters.
    • Posterior uveitis: Affects choroid and retina; can lead to visual loss.
    • Panuveitis: Involves inflammation across all three parts.
  • What are the common symptoms of uveitis?
    • Eye pain
    • Redness
    • Sensitivity to light (photophobia)
    • Blurred vision
    • Floaters
    • Swelling
    • Watering eyes
    • Eye discharge
  • What are the treatment options for uveitis?
    • Corticosteroid eye drops or injections
    • Dilating eye drops
    • Antibiotics or antiviral medications
    • Immunosuppressive drugs for severe cases
