What is Macular Degeneration?
Macular degeneration is a progressive disease in which the central retina deteriorates. The dry (atrophic) form brings atrophic pigment epithelial changes and slow, mild central vision loss. The wet form brings subretinal neovascularization that leaks, hemorrhages, and scars, producing significant central vision loss.
Nursing Care Plans and Management
Nursing Problem Priorities
- Recognize and assess macular degeneration.
- Monitor visual changes.
- Educate the patient about the condition.
- Support optimal visual function.
Nursing Assessment
Assess for the following:
- Blurred central vision
- Distorted or wavy lines
- Dark or empty areas in central vision
- Difficulty recognizing faces or reading fine print
- Decreased color perception
- Straight lines that look crooked or wavy
- Visual hallucinations (rare)
Nursing Interventions and Actions
1. Assessing Visual Acuity and Optimizing Visual Function
Assess the patient's ability to see and perform activities. This is your baseline for tracking change.
Assist with diagnostic procedures and explain each one:
- Indirect ophthalmoscope. Fundus exam through a dilated pupil reveals gross macular changes.
- Amsler grid. Monitors central visual field loss; teach the patient to use it at home.
- IV fluorescein angiography. Sequential photographs show leaking vessels as the dye fills the subretinal neovascular net.
Send the patient to an ophthalmologist at least yearly. Yearly exams catch progressive loss and complications.
Give plenty of light, and kill the glare. Older eyes need twice as much light as younger ones. Position lighting to avoid reflections off walls and reading material, and keep a night light in the room since older eyes adjust slowly to changes in light level.
Use large-print materials and visual aids when teaching.
Explain laser surgery for the wet type. It can help if done early. Only about 20% of patients gain any visual improvement when it is done later.
2. Preventing Injury
Lost central vision and age-related changes raise the risk of falls and collisions, and the disease itself keeps the macula deteriorating.
Assess the degree of visual impairment. Severity drives the plan.
Connect the patient to low-vision aids. Optical aids improve quality of life for patients with good peripheral vision.
Make the room safe: adequate lighting, furniture against the walls, no loose rugs or clutter.
Keep glasses and the call bell within reach.
Teach the patient and family to keep the environment safe. Sunglasses cut glare, and bright contrasting colors in furnishings improve visual discrimination.
Frequently Asked Questions
What is macular degeneration? It is a progressive disease in which the central retina deteriorates. The macula controls sharp, straight-ahead vision, so as it breaks down the patient loses the center of their visual field (National Eye Institute).
What is the difference between dry and wet macular degeneration? The dry (atrophic) form brings atrophic pigment epithelial changes and slow, mild central vision loss, and it is the more common type. The wet form brings subretinal neovascularization that leaks, hemorrhages, and scars, producing significant and faster central vision loss.
What vision is lost and what is preserved? Macular degeneration takes the center of vision and leaves the edges. Faces blur, straight lines bend, and reading gets hard, but peripheral vision usually stays, which is what the nurse builds the safety plan around.
What are the warning signs to assess? Blurred central vision, distorted or wavy lines, dark or empty areas in central vision, difficulty recognizing faces or reading fine print, decreased color perception, and straight lines that look crooked. The Amsler grid helps the patient monitor central field loss at home.
What are the nursing priorities? Education, low-vision support, and keeping the patient safe and connected to eye care. The patient should see an ophthalmologist at least yearly to catch progressive loss and complications.
How do you keep a patient with macular degeneration safe at home? Provide plenty of glare-free light (older eyes need about twice as much light as younger ones), keep furniture against the walls, remove loose rugs and clutter, keep glasses and the call bell within reach, use sunglasses to cut glare, and use bright contrasting colors in furnishings to improve visual discrimination.
