Macular Degeneration

Macular degeneration is a medical condition that affects the central portion of the retina, known as the macula. This results in a loss of vision in the center of the visual field, making it difficult to see fine details or perform tasks that require sharp vision, such as reading and driving.

The condition can be classified as either dry or wet, with the former being more common in which the macula becomes thin and brittle leading to the loss of vision. Wet macular degeneration is more severe and occurs when abnormal blood vessels grow in the retina and leak blood and fluid leading to irreversible loss of central vision.

Detecting and treating macular degeneration early can prevent its progression, which is a major cause of vision loss in people over 60 years old. More than 30% of adults aged 75 or older have advanced or intermediate age-related macular degeneration.

Risk factors for Macular Degeneration

Aging increases the risk of macular degeneration. Genetics and environment may also elevate risks like a genetic variant known as complement factor H. Females with light skin or eye color are more vulnerable. Half the cases of blindness from macular degeneration arise from this deficiency. The risk of advanced macular degeneration increases with age for all patients.
Other factors that may increase the risk of developing macular degeneration include:

  • Obesity
  • Smoking
  • High-fat diet
  • Elevated cholesterol levels
  • Prolonged sun exposure
  • High blood pressure
  • Certain medications

Patients can minimize their risk of macular degeneration by exercising, eating a diet rich in Omega-3 fatty acids, and getting regular eye examinations.

Types of Macular Degeneration and their symptoms

Macular degeneration can be classified as either dry (non-neovascular) or wet (neovascular).

Dry macular degeneration is a common condition that causes gradual changes to the central vision of patients. Some symptoms include shadowy areas in the central vision, fuzzy and distorted vision, difficulty perceiving colors, difficulty seeing fine details, and blind spots in the central vision. In its advanced stages, macular degeneration can cause patients to develop larger and larger blind spots, making it difficult to recognize faces, drive, or read.

Wet macular degeneration is a more severe form of disease that can occur if the dry form advances. Patients with wet macular degeneration may experience straight lines appearing wavy or crooked, and central vision loss can occur rapidly, sometimes even in a matter of days or weeks.

If you are diagnosed with macular degeneration, it may be necessary to make many lifestyle changes as the disease progresses. While patients may lose the ability to drive or read, they usually retain peripheral vision, which enables them to manage their day-to-day activities independently.


Macular degeneration is a very serious eye condition that affects people as they age. It is an irreversible condition that can result in permanent loss of central vision over time. This is why early detection and diagnosis of macular degeneration is so important for preserving a person’s vision.

Our eye health professional can detect early signs of the disease in your eyes before noticing any symptoms during a regular eye examination. This is one reason why it’s important to see your eye doctor regularly, regardless of whether you think you have problems or not.

Our eye health professional can detect the early signs of macular degeneration through a variety of tests, including:

  • Eye examination: During an eye examination, our eye doctor may look at your macula and retina to detect signs of damage or disease.
  • Amsler Grid test: The Amsler Grid test is a simple test that allows our eye doctor to evaluate your central vision. During this test, you will look at a grid of lines and squares and indicate any areas where the lines appear distorted or wavy.
  • OCT imaging: Optical coherence tomography (OCT) is a non-invasive imaging test that creates high-resolution images of the retina. This test can detect signs of damage to the retina and macula.

Once a diagnosis is confirmed, treatment can begin right away, helping to prevent the progression of the disease. Some treatments may include medication or laser therapy.

It’s important to understand that macular degeneration is an irreversible condition, and while treatments can slow its progression or manage its symptoms, there is no known cure. Therefore, early detection and treatment are essential to preventing permanent vision loss.


The best treatment method for each patient with macular degeneration is based on the severity of the condition, the type, and how much vision has been lost. Here are some possible treatments:

  • Wet macular degeneration: This type of macular degeneration can be treated using intraocular injections of vascular endothelial growth factor. This treatment has been proven effective in stopping the growth of abnormal blood vessels which are the hallmark of this condition. Patients typically receive monthly injections into the vitreous of the eye to control the damaging effects of wet macular degeneration.
  • Photodynamic Therapy: Another approach to treating wet macular degeneration is photodynamic therapy. This treatment method focuses on eliminating newly developing abnormal blood vessels by using a combination of light-sensitizing medication and laser therapy.
  • Dry macular degeneration: Vitamin and mineral supplements, such as zinc and Vitamin C, may help to clear out toxic substances, slowing the progression of dry macular degeneration in some patients.

Regardless of the type of macular degeneration, it is crucial for patients to seek regular medical treatment and care to manage the condition and prevent permanent vision loss. The earlier the condition is diagnosed and treatment initiated, the better the outcome will be for the patient.
