Macular degeneration refers to a spectrum of conditions that result in severe loss of central vision. These conditions can range from macular changes to the eyes, new blood vessel formation, and scarring.

Naturopathic Assessment

Causal Factors

In order to stimulate the innate ability of the body to heal the causes of disease must be identified and addressed. With macular degeneration, the causes are variable and include lifestyle and external factors. A detailed assessment is required to determine which factors are contributing to macular degeneration.

Lifestyle

  • A diet low in vitamin A and E and high in salt is association with increased risk of macular degeneration.[1]
  • Alcohol consumption increases the risk of developing age-related macular degeneration.
  • Poor posture can be found to increase the risk of macular degeneration formation.

Environmental

  • Sunlight
  • There is a link between ultraviolet exposure and macular degeneration.[2]
  • Free radicals, which are highly reactive chemicals that cause oxidation and are also natural byproducts of metabolism.[3]

External

  • Smoking may increase the risk of developing macular degeneration.[4]
  • Trauma
  • Trauma such as a blow, cuts, radiation, or intense hot/cold is associated with increased risk.

Medical Interventions

  • Prescription Medications
  • Eye drops containing steroids can increase the risk of macular degeneration.

Physiology

  • Age
  • The risk of macular degeneration increases with age, particularly in individuals over 50.[5]
  • Age-related macular degeneration has been found to run in families.[6]

Diagnostic Testing

The diagnosis of macular degeneration is generally based on the age of the patient and the clinical presentation of signs and symptoms. The Amsler grid test may be used to detect central visual field deficits. Further opthalmoscopic examination may reveal the presence of drusen (yellow pigmentation) or blood at the site of the macula.

Related Symptoms and Conditions

Individuals with the following conditions have an increased risk of macular degeneration.[7]

Characteristics

Macular degeneration can be classified as two types: Atrophic (dry) macular degeneration, and Exudative (wet) macular degeneration.

  • Atrophic or dry macular degeneration accounts for 90% of cases, and is characterized by thinning and loss of tissues underlying the macula.
  • Exudative or wet macular degeneration occurs with leakage of fluid from blood vessels, which eventually leads to scarring. It is associated with more profound and rapid loss of vision.

Common Symptoms

Common signs and symptoms of macular degeneration include:

  • Early presentation of decreased reading acuity or decreased night vision.
  • Loss of central vision
  • Distortion of vision
  • Field loss, also referred to as central scotoma
  • Drusen, or yellowish deposits on the macula which can be hard, soft, large(>125mcm), or small
  • Macular pigmentation in surrounding areas
  • Hemorrhage at macula

Naturopathic Treatment

The goal of naturopathic treatment is to support and work in tandem with the healing power of the body and to address the causal factors of disease with individual treatment strategies.

It is always advisable to work with a naturopathic doctor before engaging in any treatment plan.

Home Care

Home Care strategies include:

  • Yearly eye exams are important in order to monitor the progression of the condition.
  • Wear UV-protecting sunglasses and hats if spending a lot of time in intense sunlight.
  • If you have the start of macular degeneration you may find that magnifying glasses, closed circuit television, and large-print reading material are beneficial.

Lifestyle

Lifestyle recommendations include:

  • Address any dietary triggers
  • Ensure you drink adequate water.
  • Practice eye exercises daily.
  • In general, regular exercise is important to increase blood flow and oxygen to the eyes. It can also help rebalance postural muscles, thereby helping to maintain proper alignment of the spine
  • Obtain adequate sleep to give your eyes a good rest.
  • Take regular computer breaks every 30-40 minutes.

Naturopathic Therapies

The prescribing of naturopathic therapies requires the guidance of a naturopathic doctor as it depends on a number of factors including the causal factors, a person's age, prescription medications, other conditions and symptoms and overall health. It is always advisable to work with a naturopathic doctor prior to taking any natural therapies.

Naturopathic Therapies for macular degeneration include:

.

  • Hot/cold water applications can be useful for macular degeneration
  • Naturopathic manipulation may be beneficial, especially if the macular degeneration is due to postural misalignment
