When the nurse is gathering history from a client newly diagnosed with glaucoma, the client reports the following statement to the nurse. Which statement would be consistent with the client's diagnosis?
Explanation & Rationale
Choice A rationale Seeing distant objects better than close ones is a sign of hyperopia, or farsightedness, rather than glaucoma. In hyperopia, the light focuses behind the retina instead of on it. While this involves a change in visual acuity, it does not relate to the increased intraocular pressure or optic nerve damage seen in glaucoma. Glaucoma primarily affects peripheral vision first, leaving central vision intact until the advanced stages. Choice B rationale Tearing and itching are characteristic symptoms of allergic conjunctivitis or dry eye syndrome. These symptoms are caused by environmental irritants or an inflammatory response on the ocular surface. They do not indicate the internal pathological changes associated with glaucoma. Glaucoma is often a silent disease that progresses without surface irritation, making regular intraocular pressure screenings essential for early detection and prevention of permanent vision loss. Choice C rationale Difficulty matching colors, particularly blue and yellow, is often associated with the formation of cataracts or certain types of retinal disease. As the lens yellows with age or opacities develop, color perception can be significantly altered. While glaucoma can eventually affect color vision as the optic nerve sustains damage, it is not the hallmark early symptom reported by clients. Color vision deficits are more indicative of lens or retinal issues. Choice D rationale Seeing halos around lights and experiencing peripheral vision loss are classic signs of glaucoma. Increased intraocular pressure, often exceeding the normal range of 10 to 21 mmHg, causes damage to the optic nerve fibers. This damage manifests as tunnel vision, where the client can see straight ahead but loses the ability to see objects or people to the side. The perception of halos is frequently associated with acute angle-closure episodes.
