Understanding Drusen: The Yellowish Deposits in Your Eyes
As we get older, drusen may appear in our retina. This can affect our vision. Drusen are yellowish spots found in the eyes of people over 50, often linked to age-related macular degeneration (AMD).
Definition and Basic Characteristics
Drusen look yellowish and are found in the macula, key for central vision. Drusen on the retina can signal AMD, a serious condition that can cause vision loss if not treated.
Drusen form when the retina’s waste removal system fails. Normally, the retina cleans up waste. But when it can’t, waste builds up, creating drusen.
- Drusen can vary in size and number.
- They are more common in older adults.
- The presence of drusen can be an indicator of ARMD drusen.
Where Retinal Drusen Form in the Eye ?
Drusen form between the retinal pigment epithelium and the choroid, a layer of blood vessels and connective tissue. This spot is close to photoreceptor cells, vital for vision.
The buildup of drusen in the macula can cause Retinal drusen diseases, leading to vision issues. Knowing where drusen form and their nature is key for early detection and treatment.
In summary, drusen are yellowish spots caused by the retina’s waste system failing. They are a big worry for older adults and can signal AMD. Spotting drusen early is important for timely medical care.
The Formation Process of Retinal Drusen
Recent studies have uncovered how drusen form, showing the retina’s role in waste removal. Drusen are yellowish spots that build up in the eye, mainly in the macula. They are linked to age-related macular degeneration (AMD).
The growth of Retinal drusen diseases is tied to the retina’s waste removal system. If this system fails, waste builds up, causing drusen spots.
The Retina’s Waste Processing System
The retina has a complex system for removing waste. This system is key to keeping the retina healthy and preventing drusen buildup.
Research found that changes in the AKT2 protein affect lysosome function. Lysosomes break down and recycle waste. Their malfunction can lead to drusen eye disease.
AKT2 Protein and Lysosome Function
The AKT2 protein is vital for lysosome function. Studies have shown that AKT2 changes can affect lysosome waste processing. This leads to drusen buildup.
Understanding what are drusen in the eye and their formation is key to treating Retinal drusen diseases. By studying recent research, we can learn more about drusen formation. This helps us find new ways to treat these diseases.
Common Types of Retinal Drusen Diseases
Drusen are yellowish deposits in the retina. They can be classified into different types based on their look and where they are. Knowing these types helps doctors diagnose and treat eye problems better.
Soft Retinal Drusen
Soft retinal drusen are bigger and have fuzzy edges. They are linked to a higher risk of Age-related Macular Degeneration (AMD). Their presence shows a big problem with the retina’s waste removal.
Hard Retinal Drusen
Hard retinal drusen are smaller and have clear edges. They are usually not as serious but need to be watched by eye doctors.
Reticular Pseudodrusen
Reticular pseudodrusen look like a net on scans. They are linked to a higher risk of AMD and can speed up the disease.
Pachydrusen
Pachydrusen are big and often linked to other eye problems. They show there might be other issues that need to be fixed to save your vision.
In summary, knowing the types of drusen like soft, hard, reticular pseudodrusen, and pachydrusen is key. Regular eye checks and new imaging tools help spot and track Retinal drusen diseases.

People often need more light to read. They might also see things distorted because of drusen.
Progression of Vision Changes Over Time
How vision changes with drusen varies. Some see vision slowly get worse. Others notice changes faster.
It’s important to watch drusen closely. This helps understand how they affect vision. It also helps manage vision problems better.
The Connection Between Drusen and Age-Related Macular Degeneration
Age-related macular degeneration (AMD) often starts with drusen, yellowish spots under the retina. These spots are a key sign of AMD and raise the risk of getting it.
Drusen as an Early Sign of AMD
Drusen are an early sign of AMD. Large drusen show a higher risk of AMD getting worse. People with large drusen are more likely to lose a lot of vision.
Drusen are not just age spots. They are important for checking retinal health. The size, number, and where drusen are can tell us a lot about AMD risk. For example, soft drusen are more linked to AMD than hard ones.
Progression from Drusen to AMD
Going from drusen to AMD is complex. It involves genetics, environment, and age. As drusen grow, they can harm the RPE, a key part in AMD.
Several things can make drusen turn into AMD, including:
- Age: AMD risk goes up with age.
