Abstract
Argon laser is the most famous type of lasers.
Argon laser radiation was generated by incidence of photons on an
activated argon gas atoms. Activation was achieved by increasing
the gas temperature to a certain degree. The resulting
radiation are in the same wave length and coherence.
Retinal pigment epithelium and haemoglobin absorbe argon laser
irradiation very well. So. Argon laser has a great effect on
differ(nt diseases of the retina and blood vessels. It is
effective in any part of the retina except the macula
In macular diseases. argon las’ar usage as a

situation.
Argon laser irradiation was effective in anterior and
segments of the eye. We deal now with anterior
diseases.
Argon laser decreases the postoperative recurrence rate of the
pterygium. put it can be used from th2 s~art as a treatment of
pte~ium At the cornea. it can photocoagulate penetrating
neovessels which result from different corneal diseases or after
keratoplasty.
Argon laser can eliminate retrocorneal plaque. Vitreous band
which is attached to corneal wound can be cut by argon laser
Argon laser has a great role in treatment of different types of
glaucoma. It can treat primary type (acute or chronic) or
secondary type, even malignant type.It has a prophylactic role to
prevent neovascular glaucoma. It can also reopen occluded
filteration fistulae.

Argon laser can cut the posterior synaechiae.
It reforms updrown pupil to be centralized. If the sphincter of
the iris was fibrosed by long usage of miotics. Argon laser can
dilate the pupil and improve visual acuity.
It can treat iris and ciliary body cysts. IridocycIitic
membrane can be photocoagulated by argon laser before surgical
incision to avoid bleeding .
Cyclodialysis cleft can also be treated by argon laser
photocoagulation to avoid the hypotony.
Complications of argon laser are very little.as local lens
opacities. temporary iridocyclitis and temporary increase in
intraocular pressure. The complications are easy to control.
