Today we’re tackling an important topic: macular degeneration. This eye condition can have a significant impact on your quality of life, but with the right care and management, you can mitigate its effects.
What is macular degeneration?
Macular degeneration is an eye disease that affects the macula, the central part of the retina responsible for central vision. This condition causes a progressive loss of central vision, making everyday tasks such as reading, driving, or recognizing faces difficult.
There are two main types of macular degeneration:
Age-related macular degeneration (AMD)
This is the most common form, mainly affecting people over 60 years of age. It can be of the "dry" or "wet" type, depending on the changes observed in the macula.
Juvenile macular degeneration
Much rarer, this form generally manifests itself before the age of 60 and can have genetic causes or be linked to other medical conditions.
What are the symptoms of macular degeneration?
The first signs of macular degeneration can be subtle and go unnoticed. Here are the main symptoms to watch for:
- Blurred or distorted vision in the center of the visual field
- Difficulty distinguishing fine details
- Need more brightness for reading or performing tasks
- Distortion of straight lines
- Blind spots in central vision
It is important to consult an ophthalmologist as soon as these symptoms appear, because early diagnosis can make all the difference in the management of the disease.
What are the risk factors?
Several factors can increase the risk of developing macular degeneration:
- Age: the main risk factor, AMD mainly affecting people over 60 years old
- Family history: Some forms of the disease may have a genetic component
- Smoking: Smokers have a higher risk of developing AMD
- Exposure to blue light: Light emitted by screens, light bulbs and the sun can damage the macula
- Obesity and cardiovascular problems: These conditions are also associated with increased risk
How is macular degeneration diagnosed?
During your visit to the ophthalmologist, several examinations will be carried out to establish a precise diagnosis:
- Eye exam: measurement of visual acuity, Amsler test (distortion detection)
- Fundus examination: observation of the macula using an ophthalmoscope
- Medical imaging: angiography, optical coherence tomography (OCT) to visualize structures of the eye
These tests will allow your ophthalmologist to determine the type and stage of macular degeneration, in order to put in place the most appropriate treatment.
What treatments are available?
Treatment for macular degeneration depends on the type and stage of the disease. The main treatment options include:
For dry AMD
- Nutritional supplements: Certain vitamins and minerals may slow the progression of the disease
- Lifestyle changes: quitting smoking, protection against blue light
- Experimental therapies: cell therapy, gene therapy under study
For wet AMD
- Intravitreal injections: administration of anti-angiogenic drugs to stop the growth of abnormal blood vessels
- Photodynamic therapy: using a photosensitive drug and light to destroy blood vessels
- Surgery: In some cases, surgery may be considered.
It is important to follow your ophthalmologist's recommendations and actively participate in your care to obtain the best results.
How to live with macular degeneration?
Although macular degeneration can have a significant impact on your daily life, there are many strategies you can take to adapt and maintain your independence:
- Use of visual aids: magnifying glasses, reading glasses, screen magnification systems
- Adapting your environment: adequate lighting, high contrasts, organization of spaces
- Learning compensation techniques: reading using peripheral vision, using voice for everyday tasks
- Psychological support: sharing experiences with other people affected, cognitive therapy
With the right care and support, you can continue to live a fulfilling life despite the challenges posed by macular degeneration.
