YAG laser peripheral iridotomy is a treatment used to treat angle closure.
Angle closure is a condition which obstructs the natural drainage channels in your eye and causes the pressure in your eye to rise.
In the healthy eye, the fluid called aqueous humour flows freely into the front of your eye through the pupil then drains away through channels called the trabecular meshwork.
If you have angle closure this means that the coloured part of the eye, the iris, can move forward and obstruct the drainage channels meaning that the fluid can not escape from the eye.
This build up of fluid means your eye pressure (called intraocular pressure) increases injuring and damaging your vision.
We use YAG laser peripheral iridotomy to create a small hole in your iris to form a permanent small passage which allows the excess fluid to escape. The laser is used to push the iris tissue backward to unblock the drainage channels.
