People who are over forty will find that their vision declines gradually.
It is true that people may suffer from many kinds of aged related eye problems.
In particular, the situation will be much worse when they become much older.
For example, AMD (age-related macular degeneration) is one of such problems.
Some people will find that there are some yellow deposits bellow their retina - these deposits are called Drusen, which can be found on in those aged people and early sufferers of AMD.
The appearance of these yellow deposits will do no harm to eyes, but can indicate the worsening of eye condition as they expand in number and sizes.
If Drusen multiplies on and on, people may get AMD, which can be fallen into two types, namely wet AMD and dry AMD.
And sufferer's eye sight will also be affected in the mean time.
On the whole, Drusen can also be categorized into two groups, and can indicate the emergence of certain AMD.
Soft drusen means the emergence of wet AMD.
These deposits are results of damaged blood vessels in the eyes.
These blood vessels often leak blood to eye tissues and make retina swollen.
And the result can be very serious, like permanent blindness.
Therefore, Wet AMD is one of the most radical and horrible eye problems that can occur within very short time.
Usually, these deposits can be well detected via professional eye exams.
If these deposits appear, AMD might be there, but not absolutely.
That's to say, Drusen can not always indicate the emergence of AMD- these deposits can be found in the eyes of many aged people with perfect eye sight.
Any way, it is of vital importance for aged people to receive regular eye exams.
Doing so can really detect some potential eye diseases at early stage if the symptoms become obvious only when condition worsens.
