Introduction
Ophthalmology has developed very quickly in recent years by its achievements are the use of lasers in the treatment of retinal diseases. In this article we will look at the mechanisms of action, application, Advantages of laser coagulation, Its importance in modern ophthalmic practice.
The essence of laser coagulation
Laser coagulation involves the use of a focused laser beam, which generates heat, that can selectively affect the tissues of the eye. Laser abbreviation - stands for Light Amplification of Stimulated Emission of Radiation The main purpose of this technique is to, To cause controlled thermal damage to certain areas, leading to coagulation of blood vessels, sealing retinal breaks or destruction of anomalous tissue. Laser accuracy allows ophthalmologists to perform delicate procedures with minimal side damage to surrounding tissues.
Mechanism of action
Laser produces a concentrated ray of light, which is absorbed by special chromophores in target tissue. When laser energy is absorbed, it turns into heat, By causing denaturation or coagulation of proteins in the fabric. This reaction can lead to different results, in particular:
- Photocoagulation: Laser causes localized retinal tissue burns, closing blood vessels, bleeding.
- Panretinal photocoagulation: The "pattern" of laser burns is applied to the retina for the treatment of proliferative diabetic retinopathy and other diseases.
Application in ophthalmology
Laser coagulation has a wide range of use in ophthalmology, including for the treatment of diseases such as:
- Diabetic retinopathy: one of the main causes of blindness in adults, The course of this disease can be effectively monitored by laser photocoagulation to reduce retinal edema and prevent further proliferation of vessels.
- Ruptures and retinal detachment: Laser coagulation can be used to create a scar tissue around the retinal breaks, efficiently sealing and preventing The progression of retinal detachment.
- Age-related macular degeneration (AMD): In some cases, laser therapy can help destroy blood vessels with pathology and slow down vision loss.
- Treatment of glaucoma: Laser procedures, such as selective laser trabeculoplasty (SLT), can improve fluid outflow from eye, helping to reduce intraocular pressure.
- Vascular diseases: In diseases such as the occlusion of retinal vessels, Laser treatment may be useful to prevent such complications as macula swelling.
Advantages of laser coagulation
The use of laser coagulation in ophthalmology has several advantages:
- Precision: The use of a laser allows manipulations accurately and purposefully, minimizing damage to the surrounding healthy tissues.
- Minimum invasiveness: Many procedures can be performed on an outpatient, often without general anesthesia.
- Shortened recovery time: After laser intervention, patients usually recover faster, compared to traditional surgical methods.
- Effective results: proved, that laser coagulation is effective for stabilizing or improving vision in various eye diseases.
Visnovok
Laser coagulation made a revolution in the field of ophthalmology, providing effective and accurate treatment options for various retinal diseases. Since technology continues to develop, scope and effectiveness of laser treatment, probably, will expand, which will further improve the result from the procedure. People with retinal diseases laser coagulation offers an opportunity to preserve and restore vision. Regular ophthalmologist examinations and early intervention remain decisive to provide best possible results for patients, which are faced with these problems.
