Also known as AMD (Age Macular Degeneration) or ARMD (Age-related Macular Degeneration). It is a medical condition which may result in blurred or no vision in the center of the visual field. It generally occurs in old age people. In Macular degeneration the patient does not maintain central vision. Central vision means when you focus straight ahead, the centre of your vision or the point you want to see is not clear or is blurred.
Macular degeneration is a painless eye disease which affect the Macula of the eye. The macula is the small area at the centre of the retina responsible for what we see straight in front of us, at the center of our field of vision. The macula is very important as it gives us the vision needed for detailed activities such as reading and writing, and the ability to appreciate colour.
In macular degeneration following problems are faced by the patient.
- reading and writing becomes difficult
- colours appears vibrant
- familiar faces becomes unrecognized
Causes of Macular Degeneration:
The macula is the small area at the centre of the retina responsible for what we see straight in front of us, at the centre of our field of vision. The macula is very important as it gives us the vision needed for detailed activities such as reading and writing, and the ability to appreciate colour. By the passage of age the light sensitive cells starts breaking down. This process occurs very slowly and go through years to reach on its extreme position. Therefore the main factor which cause Macular degeneration is age. However there are some other causes which cause Macular degeneration.
- High blood pressure
- A diet enriched with unsaturated fats
- Lack of exercise
etc can cause Macular degeneration. There are two types of Dry Macular Degeration and Wet Macular Degeneration.
Wet Macular Degeneration:
Wet macular degeneration is a chronic eye disease that causes blurred vision or a blind spot in your visual field. It’s generally caused by abnormal blood vessels that leak fluid or blood into the macula.
Dry Macular Degeneration:
Dry macular degeneration is an other common eye disorder which is often found in people over 60 years. It generally starts from one eye and then develops into the other eye too. Over time it worsens your vision and you become unable to recognize the faces.
