## 문제

A nurse is assessing a 70-year-old client for risk factors related to eye problems. Which finding would be most concerning and require immediate follow-up?

During a routine health assessment, the nurse identifies several potential risk factors for eye problems in an older adult client.

## 보기

1. Family history of glaucoma
2. Occasional use of reading glasses
3. Sudden onset of flashing lights and floaters **✔ 정답**
4. History of diabetes mellitus for 10 years

**정답: 3**

## 해설

Sudden flashing lights and floaters suggest retinal detachment, an emergency needing immediate follow-up. Other options are chronic risk factors requiring monitoring but not urgent action.

Clinical Reasoning Analysis

This question tests your ability to prioritize ocular symptoms in an older adult based on the urgency of the underlying pathology. While all options represent valid considerations in eye health, the key is to distinguish between chronic risk factors and acute presentations that signal a time-sensitive, vision-threatening emergency.

Option 1 (Family history of glaucoma) and Option 4 (History of diabetes mellitus for 10 years) are significant chronic risk factors. A family history is a well-established, non-modifiable risk for primary open-angle glaucoma, and a 10-year history of diabetes substantially increases the risk for diabetic retinopathy. However, these are conditions that require scheduled, comprehensive dilated eye exams for monitoring and early intervention, not immediate emergency department triage. Option 2 (Occasional use of reading glasses) describes a normal age-related change, presbyopia, which is an expected finding and not a cause for concern.

Option 3 (Sudden onset of flashing lights and floaters) is the most concerning finding and requires immediate follow-up. This symptom complex is a classic, high-risk presentation strongly suggestive of a posterior vitreous detachment (PVD) or, more critically, a retinal tear or detachment. The pathophysiology involves the vitreous humor liquefying and contracting with age, pulling away from the retina. This traction mechanically stimulates the retina, which the brain interprets as flashes of light (photopsia). If the vitreous pulls too forcefully, it can tear the retina, allowing fluid to seep underneath and separate the sensory retina from the retinal pigment epithelium. The sudden appearance of floaters often represents blood (from a torn vessel), pigment cells, or condensed vitreous fibers. A retinal detachment is a medical emergency where the window for surgical repair to preserve sight is measured in hours to days.

A recent prospective study analyzing over 12,500 eye emergency visits has provided robust, evidence-based support for this prioritization. The multivariate analysis identified that the specific symptom of "flashing lights" (photopsia) was statistically significantly associated with a final diagnosis requiring emergency-level care [1]. This confirms that when a patient reports this acute symptom, it serves as a high-risk clinical feature that should immediately raise the triage nurse's index of suspicion for a vision-threatening retinal event. The sudden onset is the critical differentiator from the gradual, progressive nature of the other listed risk factors. A delay in assessment and treatment could lead to permanent vision loss, making this the absolute priority for immediate follow-up [1].

## 임상 시나리오

Sudden Onset Flashes & Floaters: Emergency TriageRule Out Retinal Detachment Immediately
A report of sudden, painless onset of flashing lights (photopsia) and a new shower of floaters in an older adult is a retinal detachment until proven otherwise. This is a time-sensitive ocular emergency.

The classic triad of symptoms includes photopsia, a sudden increase in floaters, and a peripheral visual field defect often described as a "curtain coming down." Immediate ophthalmology referral is required to prevent permanent vision loss.

CautionDo not delay evaluation for a full history. Instruct the patient to avoid strenuous activity and keep the head still. Chronic risk factors like diabetes or glaucoma family history require monitoring but are not emergent in the absence of acute vision changes.

## 핵심 개념

- **Posterior Vitreous Detachment (PVD)** — Age-related separation of the vitreous humor from the retina, often causing floaters and flashes, and can lead to retinal tear.
- **Retinal Detachment** — A medical emergency where the retina pulls away from its supportive tissue, characterized by sudden painless vision loss, flashes, and a curtain-like shadow.
- **Photopsia** — The symptom of seeing flashes of light, caused by mechanical stimulation of the retina, often from vitreous traction.
- **Floaters** — Small, shadowy shapes that appear in the field of vision, caused by clumps of cells or debris in the vitreous humor.
- **Presbyopia** — Age-related loss of the eye's lens elasticity, leading to difficulty focusing on close objects, a normal and expected finding.
