Cyclodiode Laser Treatment
This kind of laser therapy uses heat to permanently reduce the production of aqueous humour from the ciliary body (tissue behind the iris). Although effective, it can have unpredictable side effects and is generally reserved for end-stage glaucoma when all other treatments have failed.
Laser Peripheral Iridotomy (LPI)
Laser iridotomy cuts a tiny hole in the peripheral iris, to reduce a person’s risk of angle closure glaucoma.
This can be a stand-alone procedure, or used with other surgical treatments. It lowers fluid production inside the eye in a much more controlled fashion than cyclodiode laser.
Glaucoma surgery is used to lower eye pressure when laser or medications are not effective. Surgery can either rejuvenate your eye’s natural drainage system, or create an entirely new plumbing system for the eye.
Let’s start with the traditional glaucoma surgeries, trabeculectomy, and glaucoma tube shunts. These drain aqueous humour into a fluid-filled bubble behind your upper eyelid known as a ‘bleb’.
During trabeculectomy surgery, an opening is created in the eye, and the white sclera is fashioned into a pressure-sensitive valve. This allows fluid to slowly drain from the eye. Although newer techniques have now emerged, trabeculectomy is still a common glaucoma surgery.
Glaucoma drainage tube shunts
These are silicone implants approximately the size of a 20 cent coin. These implants shunt fluid from the eye to behind the upper eyelid, through a hollow tube
