  2. Summer 2007 First Day of School 2004

  3. Goals for the Term • Solid base of knowledge • Comfort with Ocular terminology • Basics of tissue structure & function • At the end of the course you can give yourself a 3D guided tour of the eye and orbit within your mind’s eye.

  4. Exam Schedule & Grading • Midterm 37% • Lab work sheets & hw (4%) • Quizzes: Four each 5.5% (22%) • and Final Exam 37% • some of Final is review There will be 4 or 5 Lab sessions, attendance is mandatory

  5. Sources of information • The Human Eye structure and Function by Clyde Oyster • Hand-outs, outlines including additional figures. • CD’s of power point presentations for out of class review Come to Class

  6. Texts and Supplements • Oyster (you buy this one) The Human Eye • Williams & Warwick Functional Neuroanatomy of Man(copy provided) • Snell & Lemp:Clinical Anatomy of the Eye (copy of selected figures provided)

  7. Broad-based learning • Power point presentations • Almost all lectures available on CD • Hand out outline the lecture • Study Guides • When all else fails: RTB Read the Book Go to Class

  9. Any Questions? How do I get this thing off my finger?

  10. Visual system Overview

  11. Overview • When the structure seems complicated , think FUNCTION • Imaging : OPTICAL CLARITY • Information processing: pathways, adaptation • Mobility: balance, strength, speed, MECHANICS • Biological System: respiration, pain, protection

  12. Rostral (toward top of head - rooster) Caudal (toward tail) cauda equina - horses tail Anterior - front - ventral Posterior- back - dorsal (dorsal fin) Medial (midline) {Nasal} Lateral away from midline (Temporal) Central - Peripheral- away from center Terminology

  13. Reference planes How do you know this is a diagram of the right eye?

  15. Basic components of eyeball

  16. Eyeball: Optical Pathway • Cornea • Anterior Chamber • Iris/Pupil • Posterior Chamber • Lens • Vitreous • Retina Figure by Snell & Lemp

  17. Eyeball: Layered tissues • Protective epithelium • Cornea/Sclera • Choroid • RPE • All to protect/nourish the nervous tissue of retina/optic nerve

  18. Uvea: uveal layer is shown in red: It consists of the iris, ciliary body and choroid From Williams & Warwick

  19. Neuronal function
