Main Document What is an Aging Associated Disease An aging associated disease is a disease that is seen with increasing frequency with increasing senescence. Age associated diseases are to be distinguished from the aging process itself because all adult humans age, but not all adult humans experience all age-associated diseases.

Share Your Story Laser therapy There are several forms of laser therapy for glaucoma. Laser iridotomy see the section above on angle-closure glaucoma involves making a hole in the colored part of the eye iris to allow fluid to drain normally in eyes with narrow or closed angles.

Argon laser trabeculoplasty and selective laser trabeculoplasty SLT are laser procedures performed only in eyes with open angles. Laser trabeculoplasty does not cure glaucoma, but may be done instead of increasing the number of different eyedrops, or may be recommended when a patient is already using multiple eyedrops maximal medical therapy.

In some cases, it is used as the initial or primary therapy for open-angle glaucoma. This procedure is a quick, relatively painless, and safe method of lowering the intraocular pressure. With the eye numbed by anesthetic drops, the laser treatment is applied through a mirrored contact lens to the angle of the eye.

Microscopic laser burns to the angle allow fluid to better exit the drainage channels. Laser trabeculoplasty is often done in two sessions, weeks or months apart. Unfortunately, the improved drainage as a result of the treatment may last only about two years, by which time the drainage channels tend to clog again.

There are different types of laser trabeculoplasty including argon laser trabeculoplasty ALT and selective laser trabeculoplasty SLT.

American Academy of Neurology Journals

ALT is generally not repeated after the second session due to the formation of scar tissue in the angle. SLT is less likely to produce scarring in the angle, so, theoretically, it can be repeated multiple times. However, the likelihood of success with additional treatments when prior attempts have failed is low.

Thus, the options for the patient at that time are to increase the use of eyedrops or proceed to surgery. Laser cyclo-ablation also known as ciliary body destruction or cyclophotocoagulation is another form of laser treatment generally reserved for patients with severe forms of glaucoma with poor visual potential.

This procedure involves applying laser burns to the part of the eye that makes the aqueous fluid ciliary body. This therapy destroys the cells that make the fluid, thereby reducing the eye pressure.

This type of laser is typically performed after other more traditional therapies have failed. Cyclocryopexy is the use of freezing, rather than laser, to achieve a similar purpose of reducing aqueous production.

Glaucoma surgery Trabeculectomy is a delicate microsurgical procedure used to treat glaucoma.

In this operation, a small piece of the clogged trabecular meshwork is removed to create an opening and a new drainage pathway is made for the fluid to exit the eye.

As part of this new drainage system, a tiny collecting bag is created from conjunctival tissue. The conjunctiva is the clear covering over the white of the eye.

This bag is called a "filtering bleb" and looks like a cystic raised area that is at the top part of the eye under the upper lid. Trabeculectomy is the most commonly performed glaucoma surgery.

If successful, it is the most effective means of lowering the eye pressure. Aqueous shunt devices glaucoma implants or tubes are artificial drainage devices used to lower the eye pressure.

They are essentially plastic microscopic tubes attached to a plastic reservoir. The reservoir or plate is placed beneath the conjunctival tissue.

The actual tube which extends from the reservoir is placed inside the eye to create a new pathway for fluid to exit the eye. This fluid collects within the reservoir beneath the conjunctiva creating a filtering bleb. This procedure may be performed as an alternative to trabeculectomy in patients with certain types of glaucoma.

Shunts used today are either valved Ahmed type or non-valved Baerveldt type. Mini shunts without a reservoir are also used to improve safety and reduce the post-surgery chance of pressures that are too low.

In the past few years, minimally-invasive glaucoma surgery MIGS has been under development and is more frequently used as a surgical procedure. Various devices such as the Trabectome, the IStent, the CyPass Micro- Stentthe Xen glaucoma implant, the Hydrus Microstent, the InnFocus Microshunt, viscocanaloplasty, and gonioscopy-assisted transluminal trabeculotomy GATT have been either approved for human use or are in advanced clinical trials.

These provide alternative surgical procedures used to lower eye pressure. These procedures are directed at creating openings in the trabecular meshwork, the drainage ring in the wall of the angle of the eye.Research Goal C: Improve our understanding of Alzheimer's disease, other dementias of aging, and the aging brain.
