Vision (English)

Visual defects are amongst the most common human problems. They range from the relatively trivial, such as inability to focus light accurately and colour - blindness, to very serious conditions that can lead to blindness. With the increasing incidence of type 2 diabetes, together with an aging population, serious eye diseases are increasing in frequency and importance. Thus some knowledge of the anatomy and physiology of the eye is essential for nurses.

There are a total of fifteen short exercises in the Vision experiment:

1. The human eye
2. The blind spot
3. Macular vision
4. Visual acuity
5. Disorders of visual acuity
6. Convergence of gaze
7. Accommodation (focusing)
8. Saccadic masking
9. Mechanical stimulation of the retina
10. The positive after-image
11. The negative after-image
12. Retinal blood vessels
13. Visual information
14. Optical illusions
15. Color blindness

Interspersed throughout these exercises are five patient case studies that demonstrate some of the physiology presented.
