Glaucoma

Went to CGH's eye specialist and was suspected for Glaucoma.
Going back for e follow up in a month time.
hopefully it's not...

I've missed cell group meeting for the third time.
Down with a very very bad flu.
And now this news startled me.
I really don't want to miss church service this sunday.
I miss-ed them...

God, provide me with a healthy body.
Take away all the viruses in me.

Amen

Glaucoma
Glaucoma accounts for 40% of blindness in Singapore. It is an eye disease where the fluid pressure within the eyeball is too high and damages the optic nerve, which carries visual impulses from the eye to the brain. This pressure build-up occurs because of an imbalance between the production and drainage of fluid within the eyeball.

Glaucoma is damaging to sight because the raised pressure can injure the delicate nerve fibres contained in the retina and the optic nerve at the back of the eyeball.
The vast majority of cases develop slowly, and the patient is normally not aware of the gradual loss of sight until very late in the disease when vision is seriously affected.

Different Types Of Glaucoma

Primary Open-Angle Glaucoma
This accounts for the majority of glaucoma cases in most countries. It affects the elderly and middle-aged. Relatives of people with glaucoma have a higher risk of having the disease as it may be inherited. The glaucoma progresses slowly and is often not noticed by the patient, as there are usually no symptoms like pain or redness. Peripheral (ie side) vision and night vision are gradually affected first. Central reading vision is affected only very late.

Acute Angle Closure
This form of glaucoma usually affects middle-aged and elderly Chinese women in Singapore. Due to a sudden blockage of the fluid outflow channel, there is a rapid, drastic rise in the fluid pressure within the eye. This results in eye pain, redness, headache, nausea and vomiting. Blurred vision and coloured rings around lights are accompanying symptoms.

Chronic Angle-Closure Glaucoma
Like Primary Open-Angle Glaucoma, this form of glaucoma progresses gradually, and often goes unnoticed for a long time. It results from progressive blockage of the drainage channels of the eyeball, and a slow prolonged rise in pressure.

Secondary Glaucoma
This is sometimes caused by inflammation of the eyeball or when a cataract becomes too advanced and swollen. Other causes are tumours, injuries and surgery to the eyeball.
