CHAPTER 16

Assessing Eyes

Chapter Overview

Assessment of vision provides important information about the client’s ability to interact with the environment

because healthy eyes are essential for vision and to perform activities of daily living. Vision informs our lives,

permits mobility, and assists learning. People without vision are handicapped indeed. Changes in vision often

occur gradually and go unrecognized by clients until a severe problem develops. Thus, an accurate history and

exam are essential to detect any abnormalities. Clients may be anxious about their eyes being examined. Therefore

it is imperative to explain in detail what you will be doing and answer any questions the client may have. This

chapter reviews the structures and functions of the eye and the tests and techniques used by nurses to evaluate a

client’s visual acuity.

Chapter Learning Objectives

1. Describe the structures and function of the eyes.

2. Discuss the risk factors for cataracts and ways to reduce those risk factors.

3. Interview a client for an accurate nursing history of the eyes and vision.

4. Perform a physical assessment of the eyes and visual acuity correctly using inspection, visual testing, and the

ophthalmoscope.

5. Dierentiate between normal and abnormal ndings of the eyes and visual acuity.

6. Describe the ndings frequently seen when assessing the older client’s eyes and visual acuity.

7. Analyze the data from the interview and physical assessment of the eyes and visual acuity to formulate valid

nursing diagnoses, collaborative problems, and/or referrals.

What action should the nurse take when testing a client's near vision?

Explanation: To test near visual acuity, the nurse should have the client hold the chart 14 inches from the eyes. The Snellen chart should be kept at eye level, 20 feet away on the wall when testing for distant vision.

When assessing a client's eye what would you assess first?

Assessment of Visual Acuity: The first part of the eye exam is an assessment of acuity. This can be done with either a standard Snellen hanging wall chart read with the patient standing at a distance of 20 feet or a specially designed pocket card (held at 14 inches).

What eye function is the nurse preparing to assess when the patient is asked to stand 20 feet from a specific chart?

The visual acuity test is used to determine the smallest letters you can read on a standardized chart (Snellen chart) or a card held 20 feet (6 meters) away.

What test would the nurse use to assess the boundaries of the client's peripheral vision?

Perimetry is used to measure the peripheral and central visual fields of each eye in a more detailed and sophisticated manner.
