  3. Accessory Structures of the Eye • Eyelids and Eyelashes

  4. Accessory Structures of the Eye • Lacrimal Apparatus

  5. Word Analysis and Definition • Make the following terms plural: - orbit - canthus - duct

  6. Word Analysis and Definition • Pronounce and define the meaning of the word: conjunctiva kon-junk-tie-vah • Add the suffix -itis to the term and define it: conjunctivitis

  7. Word Analysis and Definition • Identify the suffixes of the following words and define the terms: - ophthalmologist - logist - periorbital - al - purulent - ulent

  8. Disorders of the Accessory Glands • Conjunctivitis

  9. Disorders of the Accessory Glands • Chalazion • See figure 4.5 page 102 of the text

  10. Disorders of the Accessory Glands • Blepharitis • See Figure 4.6 page 102 of the text.

  11. Disorders of the Accessory Glands • Dacryostenosis - blockage • Dacryocystitis - infection

  12. Disorders of the Accessory Glands • Ptosis

  13. Word Analysis and Definition • Identify the root and combining forms of the following terms and define them: - blepharoplasty blephar-root o-combining form - photophobia phot-root o-combining form

  14. Extrinsic Muscles of the Eye • Stereopsis

  15. Extrinsic Muscles of the Eye • Strabismus

  16. Extrinsic Muscles of the Eye • Esotropia - congenital esotropia - accommodative esotropia

  17. Extrinsic Muscles of the Eye • Exotropia • Amblyopia

  18. Word Analysis and Definition • Explain the difference(s) between the following sets of terms: - esotropia vs. exotropia - ophthalmologist vs. optometrist - extrinsic vs. intrinsic

  19. Special Senses of the Eye and Ear Lesson 4-2: The Eyeball and Seeing

  20. The Eyeball and Seeing • Eyeball

  21. The Eyeball and Seeing • Keynote: “ The cornea protects the eye, and by changing shape, provides about 60% of the eye’s focusing power. The pupil controls the amount of light entering the eye. The lens changes its shape to focus rays of light onto the retina.”

  22. The Eyeball and Seeing • Keynote: “Both the cornea and lens refract light rays. Neither has a blood supply which compromises healing from injury or disease.”

  23. Word Analysis and Definition • Write the term, pupil, in the plural and adjective forms: - plural = pupillae - adjective = pupillary

  24. Word Analysis and Definition • Place the structures in order from the outside of the eyeball to the innermost portion of the eyeball: - retina - lens - iris - cornea - pupil

  25. Word Analysis and Definition • Answer: Place the structures in order from the outside of the eyeball to the innermost portion of the eyeball: - outermost: cornea iris pupil lens - innermost: retina

  26. The Eyeball and Seeing • Eyeball - retina

  27. The Eyeball and Seeing • Keynote: “Rods of the retina perceive only dim light, and not, color. Cones of the retina perceive bright light and color. Rods and cones are called photoreceptor cells.”

  28. The Eyeball and Seeing • Eyeball - segments of the eye

  29. Word Analysis and Definition • Describe the relationship between the following three terms: - macula lutea - fovea centralis - visual acuity

  30. The Eyeball and Seeing • Visual Pathway

  31. The Eyeball and Seeing • Visual Pathway - refraction

  32. Word Analysis and Definition • The following terms deal with image perception. Explain the differences in the terms: - emmetropia - hyperopia - myopia

  33. Word Analysis and Definition • From the following elements, identify the one that is a root: - ation - opia - ism - hyper

  34. The Eyeball and Seeing • Disorders of the Anterior Eyeball - conjunctivitis - corneal abrasion - scleritis - uveitis

  35. The Eyeball and Seeing • Disorders of the Anterior Eyeball - glaucoma

  36. The Eyeball and Seeing • Disorders of the Anterior Eyeball - cataracts

  37. Word Analysis and Definition • What do the following terms have in common? - abrasion - allergen - pollutant

  38. The Eyeball and Seeing • Diseases of the Retina - macular degeneration

  39. The Eyeball and Seeing • Diseases of the Retina - retinal detachment “shadow invasion”

  40. The Eyeball and Seeing • Diseases of the Retina - diabetic retinopathy

  41. Word Analysis and Definition • Define the meaning of the following root elements: - crani - leuko - coagul - blast

  42. The Eyeball and Seeing • Ophthalmic Procedures - examination of the retina - color vision • See Figure 4.28 page 116 of the text.

  43. The Eyeball and Seeing • Ophthalmic Procedures - distance vision

  44. The Eyeball and Seeing • Ophthalmic Procedures - near vision

  45. Word Analysis and Definition • Your optometrist tells you your far vision is 20/20. This measurement was measured by which testing method? - Ishihara color system - Jaeger reading card - Snellen letter chart - tonometer

  46. Special Senses of the Eye and Ear Lesson 4-3: The Ear and Hearing
