this Intermediate Med-Surg episode, we explore Chapter 22 of Lewis’s Medical-Surgical Nursing, covering the structure and function of the visual system along with how to assess and manage common visual problems. From normal anatomy to conditions like cataracts, glaucoma, macular degeneration, and retinal detachment, we review what nurses need to know for accurate assessment and safe patient care. You’ll also learn how to recognize signs of eye trauma and perform targeted evaluations, including pupil checks, acuity tests, and IOP measurements. This is a practical guide for anyone reviewing sensory perception or preparing for clinicals in adult health.
