ALT and SLT (Selective Laser Trabeculoplasty) are
laser treatments of the drain of the eye to reduce the
pressure. Their effect of pressure lowering is excellent
but may last for only 2-3 years. Laser iridotomy is a
laser procedure used to prevent angle closure glaucoma.
Surgical management of glaucoma is generally reserved
for those cases that cannot be controlled by glaucoma
drops or laser therapy. Procedures such as
Trabeculectomy, Goniotomy, Tube Shunts, Viscocanalostomy,
and microshunts work by creating a shunt to enhance the
fluid out flow thereby lowering intraocular pressure.
One of the most common methods for lowering eye
pressure is cataract surgery. While this does not work
in all cases, studies have shown that cataract surgery
alone lowers intraocular pressure by as much as 30%.
