Photocoagulation

Photocoagulation is the destruction of tissue by heat that comes from a light source illuminating that tissue. In some eye diseases, photocoagulation is used to destroy the diseased retina (for example, as a result of a complication of diabetes mellitus - diabetic retinopathy). In addition, it is often used in cases of retinal detachment to create adhesions between the retina and the choroid to strengthen the retina.

Retinal photocoagulation is usually performed using an argon or diode laser. The laser beam is directed directly to the areas of the retina that need treatment. Under the influence of laser radiation, local heating and destruction of pathologically altered retinal tissue occurs.

Thus, photocoagulation is an effective method for treating a number of serious retinal diseases, allowing patients to preserve and improve their vision.

Photocoagulation: the use of laser radiation to treat eye diseases

Photocoagulation is a method of treating eye diseases that uses laser radiation. It is based on the destruction of tissue under the influence of heat, which comes from a light source illuminating this tissue. Photocoagulation is used for some eye diseases to destroy the diseased retina.

One example of a disease for which photocoagulation can be used is diabetic retinopathy, which is a complication of diabetes mellitus. This disease causes damage to the retinal blood vessels, which can lead to retinal detachment and loss of vision. Photocoagulation can be used to destroy damaged areas of the retina to prevent retinal detachment and preserve the patient's vision.

In addition, photocoagulation can be used in cases of retinal detachment to create adhesions between the retina and the choroid to strengthen the retina. This technique is usually performed using an argon or diode laser.

Photocoagulation is a safe and effective method for treating eye diseases. It can help prevent the development of complications and preserve the patient's vision. However, as with any medical procedure, there are risks and side effects that must be considered by the doctor when prescribing such treatment.

Overall, photocoagulation is an important treatment for eye diseases that can help patients maintain their vision and improve their quality of life. If you are experiencing vision problems, consult your doctor to find out which therapy may be most effective for you.

Photocoagulation is an effective method of tissue destruction based on the action of intense light. It has become widely used in ophthalmology to treat various eye diseases, including retinal diseases such as diabetic retinopathy. In some cases, photocoagulation is used to strengthen a weakened retina after a detachment. This is possible due to the property of light energy to damage connective tissue.

The mechanism of action of photocoagulation is based on the principle of light absorption. It works by placing high-power visible or infrared radiation into the photoactive zone of the tissue, which absorbs light. As heat is generated in this area, it can lead to the destruction of affected cells and the restoration of physiological tissue.

For the photocoagulation procedure, an argon or diode laser is usually used. The argon laser is more powerful and provides greater depth of penetration, but has a higher risk of burning healthy areas. On the other hand, a diode laser source heats healthy tissue less and has fewer side effects. Treatment is usually carried out on the pupil, less often on the anterior or posterior chamber of the eye, using a special instrument - a laser microscope.

Photocoagulation is an effective treatment method that helps prevent the irreversible consequences of many pathological processes in the retina and reduce the risk of vision loss. However, as with any treatment method, there are limitations and side effects that may occur during the photocoagulation process. This may be due to incorrect treatment, insufficient experience of doctors, or the individual characteristics of the patient. In this regard, before photocoagulation, it is necessary to conduct a full diagnosis and consultation with an ophthalmologist.
