Types of Glaucoma:

-Open Angle Glaucoma:
The most common type, usually happen gradually with no pain in most of the cases due to gradual increase resistance in the draining site ( Trabecular Meshwork) leading to increase in the eye pressure.

The eye pressure fluctuates during the day which makes the diagnosis a challenge early stages and necessitates full optic nerve evaluation by your Doctor.

- Close angle Glaucoma:
The iris tissue occlude the drainage site (Trabecular Meshwork) leading to sudden rise of eye pressure. The vision can be suddenly blurry with headache and eye pain. This is an emergency and can lead to blindness if the eye pressure is not treated right away. People with Far Sightedness (Hyperopia) and people of Far East descent are of increased risk of developing this type f glaucoma.

-Testing Optic Nerve Fibers:
Assessment of the optic nerve is essential in diagnosis and in monitoring glaucoma to detect any progression. This can be done by clinical exam of the optic nerve and by highly specialized equipment called optical Coherence Tomography.

- Visual Field Testing:
Peripheral visual field test will detect any “non seeing spots" in the peripheral field that the patient may not be aware of in early stages. The test is done by a “computerized Perimeter" that project blinking spot of light in different locations and the patient should respond by pushing a button when he/she sees the lights. This test needs to be repeated every 6-12 months.

Laser Trabeculopalsy (ALT- SLT):
It is a laser done to the Trabecular Meshwork (the Drainage site) to improve the facility of the fluid out flow and lowering the pressure. 2 types of lasers are done either ALT or SLT. It is done for open angle Glaucoma.

Laser Iridotomy:
This laser is recommended for Closed angle Glaucoma, this laser open a tiny hole in the iris to improve the out flow of the Aqueous to the Trabecular Meshwork (the drainage site).

Trabeculectomy:
It is a surgery to create a drainage path under a flap in the sclera (white outer coat of the eye) to drain Aqueous Humor so lowering the eye pressure. As result of the surgery filtration Bleb will be made from the drained Aqueous superiorly in the Conjunctiva (The thin membrane that cover the sclera) under the upper lid.

Setons (Glaucoma Drainage Device Surgery):
Glaucoma Drainage Device is a small clear elastic tube placed into the eye and connected to a reservoir that is placed outside the eye underneath the conjunctiva (The thin membrane that covers the sclera “the white outer coat of the eye "). It is usually placed superiorly under the upper lid.
