## 문제

A 3-year-old toddler is diagnosed with strabismus (crossed eyes). The parents are concerned about their child's condition and ask the nurse about treatment options. What is the most appropriate nursing intervention to discuss with the parents?

## 보기

1. Recommend waiting until the child is older since many children outgrow strabismus naturally
2. Explain the importance of early treatment to prevent amblyopia and promote proper visual development **✔ 정답**
3. Suggest using an eye patch on the stronger eye for 12 hours daily without medical supervision
4. Advise the parents that surgery is the only effective treatment option for strabismus

**정답: 2**

## 해설

Early intervention is crucial in pediatric strabismus to prevent amblyopia and ensure proper binocular vision development. Other options like waiting, unsupervised patching, or surgery-only approaches are inappropriate.

## 심화 해설

Strabismus in a 3-year-old child is a critical developmental issue that requires prompt intervention, not a wait-and-see approach. The most appropriate nursing intervention is to explain the importance of early treatment to prevent amblyopia and promote proper visual development.

Understanding the Pathophysiology and Risks

When a child has strabismus, the eyes are misaligned and do not focus on the same point simultaneously. The developing brain receives two different visual images, which can cause confusion and diplopia (double vision). To adapt, the child’s brain will actively suppress the image from the deviating eye to create a single, clear picture. If this suppression continues during the critical period of visual development, which extends to approximately 7-9 years of age, the neural pathways from the misaligned eye to the visual cortex fail to develop properly. This results in amblyopia, a functional reduction in visual acuity in an otherwise structurally healthy eye. Amblyopia becomes irreversible if not treated early, making it a primary concern in pediatric strabismus [1]. Furthermore, strabismus impairs binocular vision and depth perception, which are essential for fine and gross motor skill development [1,4].

Why Early Intervention is Critical

The goal of treatment is not merely cosmetic alignment but the restoration of functional vision. By explaining the urgency, you help parents understand that delaying treatment can lead to permanent vision loss from amblyopia. Research on visual motor integration (VMI) in children with horizontal strabismus demonstrates that even without amblyopia, these children can exhibit significant deficits in visual perception and motor coordination compared to their peers without strabismus [4]. This underscores that the condition itself, through disrupted binocular input, can affect a child's ability to perform tasks like writing, catching a ball, and navigating their environment. Early treatment aims to realign the eyes and retrain the brain to use both eyes together, fostering proper visual pathway development and preventing these functional deficits [1,4].

Analyzing the Incorrect Options

- Option 1: Recommending a "wait and see" approach is dangerous. Strabismus does not resolve naturally and the risk of developing irreversible amblyopia increases the longer it goes untreated. The critical window for visual development demands immediate action [1].

- Option 3: While patching the stronger eye is a common treatment for amblyopia, suggesting it be done for a rigid 12 hours daily without medical supervision is inappropriate and potentially harmful. Occlusion therapy requires a specific prescription from an ophthalmologist based on the child’s visual acuity, age, and degree of amblyopia. Prolonged, unsupervised patching can induce occlusion amblyopia in the stronger eye or disrupt developing binocular vision [1].

- Option 4: Surgery is not the only effective treatment. Management is individualized and can include eyeglasses to correct refractive errors, occlusion therapy (patching), atropine penalization, prism therapy, or botulinum toxin injection, as evidenced by the comparative analysis of treatments for esotropia . Surgery is one important option, often considered when non-surgical methods fail to achieve alignment, but presenting it as the sole solution is factually incorrect and may cause undue parental anxiety .References (research sources)

## 임상 시나리오

Pediatric Strabismus: Early InterventionPreventing Amblyopia and Preserving Binocular Vision
The critical period for visual development extends to approximately 7-9 years of age. During this time, uncorrected strabismus forces the brain to suppress the image from the deviating eye to avoid diplopia, leading to irreversible amblyopia.

Treatment goals are functional, not just cosmetic. Options include corrective glasses, occlusion therapy (patching the stronger eye), atropine drops, and surgery. The specific regimen must be prescribed and monitored by an ophthalmologist.

CautionNever recommend a "wait-and-see" approach for a child with suspected strabismus. Delaying evaluation risks permanent vision loss. Patching therapy without medical supervision can induce amblyopia in the patched eye.

## 핵심 개념

- **Strabismus** — Misalignment of the eyes, causing them to point in different directions, which can lead to diplopia and amblyopia if untreated.
- **Amblyopia** — A functional reduction in visual acuity in a structurally normal eye due to abnormal visual development in childhood, often resulting from untreated strabismus.
- **Diplopia** — Double vision, a symptom caused by the brain receiving two different images from misaligned eyes.
- **Binocular Vision** — The ability to combine visual inputs from both eyes into a single, three-dimensional image, which is essential for depth perception.
