Glaucoma – Laser Therapy
There are many laser therapy options available, depending on the type of glaucoma you have.
These are described in this section
Selective laser trabeculoplasty (SLT)
This is a laser procedure which allows fluid to drain more effectively through the trabecular meshwork (the area where it is supposed to drain out of the eye).
The procedure can be completed in the clinic rooms, and requires only anaesthetic drops. Usually it is performed over two sessions, to reduce the amount of inflammation in the eye.
These sessions may be spaced a week apart. Often, the intraocular pressure is lowered sufficiently to stop one of the IOP lowering medications if you have already started on drops. This can also be used as a first line treatment, instead of using drops, if that is your preference and your type of glaucoma is suitable for treatment via this method.
Laser peripheral iridotomy (PI)
This is a treatment where a tiny, microscopic hole is made in the iris (the coloured part of the eye), to prevent fluid getting trapped behind the iris, causing the IOP to become very high.
This procedure can be performed in the clinic room, with anaesthetic drops. Typically, you will require anti-inflammatory drops for 1 week after the procedure.
This procedure is indicated for patients who are at risk of having an episode of angle closure, due to the anatomical structure of their eye. Following your examination, Dr Oakley will be able to advise you if this applies to you.
Cyclodiode
This is a laser procedure which works to decrease the amount of fluid produced by the eye, and therefore lower the IOP. It is done in the procedure room in the clinic or in theatre, and requires a short acting local anaesthetic block.
Typically, it will take 4 weeks to take effect, so any glaucoma medications you have been using will need to be continued during this time.
