Vision of Macular Degeneration and Stargardts

Age-related macular degeneration, often called AMD or ARMD, is the leading cause of vision loss and blindness among Americans who are age 65 and older. Because people in this group are an increasingly larger percentage of the general population, vision loss from macular degeneration is a growing problem. Conditions like Macular Degeneration and Stargardts often affect a significant number of individuals. (http://www.allaboutvision.com/conditions/amd.htm)

Stargardts is very similar to Macular Degeneration but occurs in younger ages…

While macular degeneration generally is associated with aging eyes, an inherited form known as Stargardt’s disease can affect children and young adults.

Stargardt’s disease — also called fundus flavimaculatus or Stargardt’s macular dystrophy (SMD) — affects approximately one in 10,000 people and is characterized by central vision loss early in life. (Some researchers believe a distinction should be made between Stargardt’s disease and fundus flavimaculatus, because they say each describes a different variant of the eye disease.) http://www.allaboutvision.com/conditions/stargardts.htm

 Vision of Stargardt Disease and Age-Related Macular Degeneration (AMD) share some similarities but also have distinct differences:

Similarities of Macular Degeneration and Stargardts:

1. Affect the Macula: Both conditions impact the macula, the central part of the retina responsible for sharp, detailed vision.
2. Vision Loss: Both lead to central vision loss, making tasks like reading and recognizing faces difficult.

Differences of Macular Degeneration and Stargardts:

1. Age of Onset:
   • Stargardt Disease: Typically begins in childhood or adolescence³.
   • AMD: Usually affects older adults, typically over the age of 65².
2. Cause:
   • Stargardt Disease: An inherited genetic disorder caused by mutations in the ABCA4 gene¹.
   • AMD: Primarily related to aging and other risk factors like smoking and diet².
3. Types:
   • Stargardt Disease: Only one type, caused by genetic mutations¹.
   • AMD: Two main types – dry (more common) and wet (less common but more severe)².
4. Progression:
   • Stargardt Disease: Progresses slowly and can vary widely in severity¹.
   • AMD: Dry AMD progresses slowly, while wet AMD can cause rapid vision loss².

Understanding these differences and similarities can help in managing and treating these conditions effectively.

Currently, there is no cure for either Stargardt Disease or Age-Related Macular Degeneration (AMD). However, there are treatments available that can help manage the symptoms and slow the progression of these conditions:

Is there a Cure?

Stargardt Disease:

• No Cure: There is no cure, but research is ongoing.
• Management: Patients are advised to protect their eyes from UV light and avoid vitamin A supplements, which can worsen the condition.

Age-Related Macular Degeneration (AMD):

• Dry AMD: No cure, but lifestyle changes like a healthy diet, quitting smoking, and taking specific vitamins (AREDS2 formula) can slow progression.
• Wet AMD: Treatments include anti-VEGF injections, laser therapy, and photodynamic therapy, which can help slow vision loss and, in some cases, improve vision.

Research is ongoing for both conditions, with hopes for more effective treatments and potential cures in the future.
