Study Guide

Objective

The student are able to
tell the following about a person whose vision cannot be significantly improved by using conventional spectacles or contact lenses. The goal is that the person can utilize the remaining vision using magnifying aids and imaging techniques: (1) definitions of low vision and blindness; (5) light and lighting, (6) peripheral vision aids, (7) eccentric viewing and "steady eye strategy", (8) environmental adaptation (9) clinical procedures (10) studies in subjects with severe visual impairment (11) ) use of complicated aids, eg telescopes mounted on eyeglass lenses (12) filter glasses
The student are able to tell
(1) Effects of aging on vision and ability to work, (2) Age-related changes in perception (not related to vision), (3) Eyelid correction in cases of aphakia and pseudo-phakia, (4) Psychological effects of vision loss, (5) Clinical management of ageing patients with multisensory loss (6) Assessment of the need for referral and consultation with other disciplines

SKILLS
The student able to
evaluate the vision of the visually impaired and the elderly
recommend vision aids for the visually impaired and the elderly
