How much do you know about diabetic retinopathy and cataract,
00:05
two common eye diseases in Malaysia?
00:08
Diabetic retinopathy is a microvascular complication that occurs in the retina.
00:15
The retina is the nerve of the eye.
00:17
And when I say microvascular, it means it affects tiny blood vessels in the eye.
00:21
The eyeball is so small, thus the blood vessels in the retina are also very fine.
00:26
Uncontrolled diabetes narrows the blood vessels and impedes oxygen flow to the nerve cells.
00:33
We usually see diabetic retinopathy in those who have uncontrolled diabetes,
00:38
when their sugars are constantly high.
00:40
At risk are those with type 1 or type 2 diabetes, as well as those who smoke or are pregnant.
00:49
Signs and symptoms would be blurry vision,
00:51
floaters, dark string-like objects moving in their vision, fluctuating vision.
00:57
Within a day, if they have sudden clear vision,
01:01
and after a meal everything becomes blurry and foggy for a couple of hours,
01:05
that is a sign of diabetes.
01:08
Or they find that their glasses suddenly are not clear, and then they go and get them changed,
01:12
and then again it becomes not clear.
01:14
So frequent change in glasses is also another sign of possible diabetes.
01:18
Prevention measures include controlling blood sugar, cholesterol and blood pressure levels,
01:25
as well as following a healthy diet and lifestyle.
01:29
As with any disease, early intervention is best,
01:33
so make it a point to screen for diabetic retinopathy alongside a comprehensive eye examination.
01:41
We all have a natural lens, and if that becomes cloudy for any reason,
01:47
then it's called a cataract.
01:48
Those who are at risk of developing a cataract are aged between 50 and 65,
01:54
or have diabetes which can speed up the progression of a cataract,
01:58
or have suffered a significant injury to the eye.
02:02
You are more prone to developing a cataract early if you have recurrent eye inflammation,
02:08
or if there is a chronic use of oral steroids.
02:11
Signs and symptoms include cloudy vision, sensitivity to light,
02:16
and frequently having to change one's glasses due to unclear vision.
02:21
These tend to come on gradually.
02:24
The only way to remove a cataract? Surgery.
02:27
With cataracts, a lot of patients come in late because they are afraid of surgery,
02:33
or they think there is no need for that.
02:35
But then that leads to them being homebound,
02:38
and not being able to do what they like, like playing golf, going for their walks,
02:43
or driving out to meet their friends.
02:45
That could lead to depression or self-isolation.
02:49
Cataract surgery now is very simple.
02:51
My advice would be to just see a doctor and get it done if it's necessary.
02:55
