It may be used to treat open angle glaucoma. It is a temporary solution, not a cure. For a more clearer understanding you may see the visual shown above. We will be very happy to receive your feedback about the visual.
So let us understand what is going on in the visual from a technical point of view. And as you get to know the entire story we are sure that you would revert to see the visual again.
A 50 μm argon laser spot is aimed at the trabecular meshwork to stimulate opening of the mesh to allow more outflow of aqueous fluid. Usually, half of the angle is treated at a time. Traditional laser trabeculoplasty utilizes a thermal argon laser. The procedure is called Argon Laser Trabeculoplasty or ALT.
A newer type of laser trabeculoplasty exists that uses a "cold" (non-thermal) laser to stimulate drainage in the trabecular meshwork. This newer procedure which uses a 532 nm frequency-doubled, Q-switched Nd:YAG laser which selectively targets melanin pigment in the trabecular meshwork cells, called Selective Laser Trabeculoplasty or SLT.
Studies show that SLT is as effective as ALT at lowering eye pressure. In addition, SLT may be repeated three to four times, whereas ALT can usually be repeated only once.
Nd:YAG Laser peripheral iridotomy (LPI)
It may be used in patients susceptible to or affected by angle closure glaucoma or pigment dispersion syndrome.
During laser iridotomy, laser energy is used to make a small full-thickness opening in the iris. This opening equalizes the pressure between the front and back of the iris correcting any abnormal bulging of the iris. In people with narrow angles, this can uncover the trabecular meshwork.
In some cases of intermittent or short-term angle closure this may lower the eye pressure. Laser iridotomy reduces the risk of developing an attack of acute angle closure. In most cases it also reduces the risk of developing chronic angle closure or of adhesions of the iris to the trabecular meshwork.
Doesn't this sound interesting? However simple the description might be, the process is not that simple. It may seem to you as a child's play to leak a swollen balloon with a pin prick but the reality is not so. It requires professional hands at their highest efficiency level.
Diode laser cycloablation
It lowers IOP by reducing aqueous secretion by destroying secretory ciliary epithelium.
Laser assisted NPDS is the performance of NPDS with the use of a CO2 laser ystem. The laser-based system is self-terminating once the required scleral thickness and adequate drainage of the intra ocular fluid have been achieved. This self-regulation effect is achieved as the CO2 laser essentially stops ablating as soon as it comes in contact with the intra-ocular percolated liquid, which occurs as soon as the laser reaches the optimal residual intact layer thickness.
Laser treatments are improving at a very brisk rate but the main problem lies with it, that still now it is not error free. Although all surgeries involve a certain amount of risk, you should consult their doctors before undergoing a laser surgery. Depending upon the complication of the disease you may go for a laser treatment and get cured.
