In ophthalmology, argon laser technology is used to perform a type of treatment called photocoagulation.
Photocoagulation is a treatment technique based on the use of a strong light source with predetermined wavelengths for tissue coagulation, where the target tissue absorbs light energy that turns into thermal energy, so this type of laser belongs to what is known as a thermal laser.
When the target tissue temperature exceeds 65 ° C, the nature of its proteins changes, and the so-called coagulated necrosis appears.
With the question of Dr. Muhammad Hantira - Honorary Assistant Professor - Department of Ophthalmology - Umm Al-Qura University - Saudi Arabia
Explain that the effectiveness of photocoagulation depends on how the light beam penetrates into the eye contour and how it is absorbed by the target tissue - the light is first absorbed by the tissues that contain melanin, xanthophyll pigment, and hemoglobin. The effectiveness of the photocoagulation zone depends on the intensity, duration and size of the light stroke used.
As Dr. Hantira explained:
Photocoagulation is treated with local anesthesia with a special contact lens suitable for the type of treatment and the eye area to be treated.
The argon laser technology is indicated for the following conditions:
• Glaucoma for iridectomy and trabeculoplasty.
• Vascular diseases of the retina, especially in diabetic retinopathy, where optical coagulation is of critical importance to prevent disease progression and blindness.
• Photocoagulation is also used in deep vein thrombosis and aneurysm processes.
• Cases of retinal vasculitis
• In all clinical cases that may lead to retinal ischemia, which can lead to what may in turn cause serious intraocular complications.
• In cases of vitreous haemorrhage and retinal detachment.
• Degenerative diseases in the peripheral retina and the presence of holes or tears at the level of the retina may lead to retinal detachment if not treated - and the argon laser is very important for its prevention.
• Diseases of the placenta, such as tumors, tumors of the blood vessels and lymph membranes.
