Macular Degeneration: Causes, Symptoms, and Home Care Solutions

Brian Callahan • October 2, 2023

According to Johns Hopkins Medicine, risk factors for Age-Related Macular Degeneration include being 50 and older, smoking, having high blood pressure and eating a diet high in saturated fat. 


Macular degeneration is a prevalent eye condition that affects millions of people around the world, including those in the New York metropolitan area, including Manhattan, Queens, Brooklyn, Nassau County, and Suffolk County. As a leading provider of home care services in New York, 7 Day Home Care is committed to raising awareness about macular degeneration, its impact, and the importance of early detection and care.


In this article, we will discuss its causes, symptoms, risk factors, and the role of home care in managing this condition. We will also provide valuable statistics to lend a greater perspective on the prevalence and significance of macular degeneration in our communities.


What is Macular Degeneration?

Macular degeneration, also known as age-related macular degeneration (AMD), is a progressive eye disease that primarily affects older adults. It damages the macula, a small but crucial part of the retina responsible for central vision. The macula enables us to see fine details and perform essential tasks like reading, recognizing faces, and driving.


Prevalence of Macular Degeneration

Macular degeneration is a widespread condition in the United States, and its prevalence is expected to increase as the population ages. Here are some key statistics:

  • According to the National Eye Institute (NEI), approximately 11 million people in the U.S. have some form of AMD, making it the leading cause of vision loss in individuals aged 50 and older.
  • The prevalence of AMD is expected to reach nearly 22 million by 2050 due to the aging population, as reported by the American Academy of Ophthalmology (AAO).

These statistics highlight the importance of understanding AMD and its potential impact on individuals and communities, including those served by 7 Day Home Care.


Types and Causes of Macular Degeneration

There are two main types of macular degeneration: dry AMD and wet AMD. Understanding the differences between these types and their causes is essential for effective management.

  • Dry Macular Degeneration

Dry AMD is the more common form of the disease, accounting for about 90% of cases. It develops when the macula thins and breaks down over time, leading to vision loss. The exact cause of dry AMD is still under study, but it is believed to involve a combination of genetic and environmental factors.

  • Wet Macular Degeneration

Wet AMD, although less common, is more severe and can cause rapid and severe vision loss. It occurs when abnormal blood vessels grow beneath the retina and leak blood and fluid into the macula. This leakage damages the macula and can lead to distorted or blurry vision. Wet AMD is often considered more challenging to manage.


Risk Factors

Certain risk factors increase an individual's likelihood of developing macular degeneration. Some of these include:

  • Age: As the name suggests, AMD is age-related, with the risk increasing significantly after the age of 50.
  • Family history: A family history of AMD can increase the risk.
  • Smoking: Smoking has been identified as a significant modifiable risk factor for AMD.
  • Race and ethnicity: Caucasians are at a higher risk of AMD than African Americans and Hispanics.
  • Obesity: Being overweight or obese can increase the risk of developing AMD.
  • Cardiovascular disease: Conditions like high blood pressure and high cholesterol are associated with a higher risk of AMD.


Prominent Statistics on Risk Factors

Let's take a closer look at some key statistics related to the risk factors for macular degeneration:

  • The American Academy of Ophthalmology reports that the risk of AMD increases with age, affecting an estimated 14% of those aged 85 and older.
  • A study published in JAMA Ophthalmology found that smoking is associated with a two-fold increased risk of developing AMD.
  • According to the National Eye Institute, individuals with a family history of AMD are at a higher risk, with a fourfold increased likelihood of developing the condition.
  • Obesity has also been linked to AMD, with a study published in JAMA Ophthalmology revealing that obese individuals have a 44% higher risk of developing early AMD compared to those with a healthy weight.

These statistics underscore the importance of addressing modifiable risk factors, such as smoking and obesity, through lifestyle changes and interventions to reduce the risk of developing macular degeneration.


Symptoms of Macular Degeneration

Recognizing the early signs and symptoms of macular degeneration is crucial for early diagnosis and intervention. Both dry and wet AMD may present with different symptoms.


Symptoms of Dry Macular Degeneration

Dry AMD typically progresses slowly, and its symptoms may include:

  • Blurred or fuzzy central vision.
  • Difficulty recognizing faces.
  • Reduced ability to read or perform tasks that require fine detail.
  • Increased sensitivity to light and glare.
  • Need for brighter light when reading or performing close-up tasks.

Symptoms of Wet Macular Degeneration

Wet AMD can lead to more sudden and severe symptoms, including:

  • Distorted or wavy central vision.
  • Dark spots or blank areas in the central field of vision.
  • Rapid loss of central vision.
  • Visual hallucinations (rare).

Prompt recognition of these symptoms is essential for timely medical intervention, which can help slow down the progression of the disease.


Diagnosis and Treatment

Early diagnosis and appropriate treatment are vital in managing macular degeneration. Regular eye exams by an ophthalmologist are essential for early detection.


Diagnosis

Diagnosing AMD typically involves the following:

  • A comprehensive eye exam: This includes a dilated eye examination, visual acuity tests, and imaging tests such as optical coherence tomography (OCT) and fluorescein angiography.
  • Amsler grid test: A simple at-home test that helps individuals monitor changes in their central vision.

Treatment

While there is no cure for macular degeneration, several treatment options are available to manage the condition and preserve vision:

  • There may be medications available through your doctor or health care professional which can slow the growth of abnormal blood vessels in wet AMD and reduce leakage.
  • Laser therapy: Laser treatment can sometimes be used to destroy abnormal blood vessels.
  • Low vision aids: Devices like magnifiers and electronic reading machines can help individuals with AMD make the most of their remaining vision.

The choice of treatment depends on the type and severity of macular degeneration and should be discussed with a qualified eye care specialist.

3 Things Most Families Don’t Know About Long-Term Care Insurance

By Brian Callahan 7 Day Home Care • October 6, 2025
3 Things Most Families Don't Know About Long-Term Care Insurance Most long-term care insurance policies don’t start paying automatically. To activate your benefits, the insured must typically need help with two or more Activities of Daily Living (ADLs)—like bathing or dressing—or have a documented cognitive impairment such as dementia. Coverage often applies only when care is provided by a licensed home care agency, n ot a private aide. Correct documentation, nurse assessments, and timely claim filing are the keys to receiving benefits smoothly. 7 Day Home Care is a licensed New York home care agency that specializes in helping families use and maximize their private long-term care insurance benefits. Many seniors and their loved ones don’t realize that most private long-term care insurance policies—such as those from Brighthouse, Genworth, CNA, MetLife, New York Life, John Hancock, Lincoln Financial, Bankers Life, UNUM and Mutual of Omaha—require that care be provided by a New York State licensed home care agency with registered nurse supervision to qualify for reimbursement. At 7 Day Home Care, every caregiver is a certified home health aide (HHA) trained and overseen by experienced RNs, ensuring full compliance with insurance and Department of Health standards. The agency assists families with policy verification, nurse assessments, care plan creation, claim preparation, and direct billing, eliminating the confusion and delays that often accompany long-term care insurance claims.

Why Cancer Spreads Despite Treatment: How It Reprograms Your Body’s Support System

By Brian Callahan 7 Day Home Care • September 17, 2025
Why Cancer Spreads Despite Treatment: How It Reprograms Your Body's Support System Cancer spreads despite treatment because it doesn’t act alone — it reprograms the healthy cells, tissues, and immune defenses around it to form what doctors call the tumor microenvironment . Instead of fighting cancer, nearby fibroblasts, blood vessels, and immune cells are “hijacked” to feed the tumor, deliver oxygen, and even shield it from the immune system’s attack. This support network also helps cancer create escape routes through new blood vessels, allowing it to spread to distant organs. Because cancer changes the very environment in which it grows, simply shrinking or removing the main tumor may not be enough - the surrounding support system must also be dismantled. This is why modern treatment often combines surgery, chemotherapy, immunotherapy, and targeted drugs that block blood vessel growth or “wake up” immune cells, giving patients a better chance to stop cancer from coming back. For cancer patients and their families, having a professional home care agency like 7 Day Home Care can dramatically improve quality of life and treatment outcomes. Our certified home health aides, supervised by experienced registered nurses, are specially trained in in-home ca ncer care, meaning they can safely manage medication schedules, monitor for side effects, and recognize early signs of infection or complications. This level of support reduces avoidable hospital visits, keeps treatment on track, and provides peace of mind for family caregivers. In addition, our team helps with daily activities, prepares nutrient-rich meals tailored to treatment needs, and ensures a safe home environment that minimizes fall risk. Emotional well-being is just as important as physical health, which is why our caregivers offer companionship and education, helping families feel confident and supported through every stage of treatment. Choosing highly experienced home care means patients can live and recover in the comfort of their own homes, surrounded by loved ones, while receiving professional oversight that aligns with their oncologist’s plan - a powerful combination for healing and hope.

Social Isolation and Dementia: Protection Guide

By Brian Callahan 7 Day Home Care • September 12, 2025
Social Isolation and Dementia: Protection Guide Planning ahead to manage loneliness and dementia risk offers enormous benefits for families, both emotionally and practically. By creating a proactive social engagement plan early — before severe cognitive decline sets in — families can help their loved ones maintain memory, communication skills, and independence for longer, which can delay the need for facility-based care. Early planning allows families to set up routines, identify meaningful activities, and arrange professional companionship or home care services that keep seniors connected and mentally stimulated. This foresight not only improves the senior’s quality of life and emotional well-being but also reduces caregiver stress, prevents crisis-driven decisions, and minimizes costly hospitalizations. Getting ahead of social isolation is one of the most powerful steps families can take to protect brain health and preserve dignity for aging loved ones.
