Physical assessment - Eyes: Nursing

Assessment of the eyes should be completed as part of a comprehensive client assessment or as part of a focused exam when a client is experiencing ocular issues, such as eye pain or blurred vision. This assessment gives the nurse information about vision and general eye health while helping to identify ocular problems at an early stage, such as glaucoma or cataracts. Assessment of the eyes includes several tests which will examine the eye itself as well as screen for ocular diseases or systemic diseases that manifest through the eye, like diabetes or liver disease. Let’s review the process of completing an eye assessment.

Okay, the supplies you’ll need for the eye assessment include a Snellen or Sloan chart, a Rosenbaum or Jaeger near vision card, a penlight, and an eye cover. You should prepare for the eye exam by ensuring you have adequate light, and that your client is comfortable in either a standing or sitting position.

Before getting started, explain the procedure to your client and be sure to answer any questions they might have before obtaining verbal consent. Then, perform hand hygiene and collect your supplies.

Now, locating the anatomical landmarks of the eyes and surrounding tissue will help guide your assessment. These landmarks include the upper eyelids and lower eyelids, eyebrows, the inner canthus and the outer canthus, pupil, lacrimal sac, conjunctival sac, and iris.

Alright, the methods of ocular assessment include inspection and palpation as well as a series of visual tests.

First, you should inspect the external eyes and the surrounding structures, starting at the eyebrows and moving downward. Eyelashes and eyebrows should be evenly distributed. Eyelids should be able to close and open all the way, and upper eyelids should extend equally over both eyes.

If an upper eyelid droops and partially covers the eye, ptosis is present, which may be due to neuromuscular weakness from conditions such as myasthenia gravis or damage to cranial nerve III.

The surrounding structures of the eyes should be without edema, puffiness, lesions, drainage or nodules.

Raised, misshaped, yellow lesions on the surrounding eye tissue, called xanthelasma, may indicate abnormal lipid metabolism.
