Laser coagulation in ophthalmology: revolutionary approach to eye treatment

Лазер для ППЛК

Вступ

Офтальмологія останніми роками розвивається дуже швидко Одним із її досягнень є застосування лазерів у лікуванні захворювань сітківки. In this article we will look at the mechanisms of action, застосування, переваги лазерної коагуляції, 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. Точність лазерів дозволяє офтальмологам виконувати делікатні процедури з мінімальним побічним пошкодженням навколишніх тканин.

Механізм дії

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, закриваючи кровоносні судини, що кровоточать.
  • Панретинальна фотокоагуляція: «візерунок» з лазерних опіків наноситься на сітківку для лікування проліферативної діабетичної ретинопатії та інших захворювань.

Застосування в офтальмології

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: при таких захворюваннях як оклюзія судин сітківки, лазерне лікування може бути корисним для запобігання таким ускладненням як набряк макули.

Переваги лазерної коагуляції

The use of laser coagulation in ophthalmology has several advantages:

  1. Precision: The use of a laser allows manipulations accurately and purposefully, мінімізуючи пошкодження навколишніх здорових тканин.
  2. Мінімальна інвазивність: багато процедур можна виконувати амбулаторно, часто без загальної анестезії.
  3. Скорочений час відновлення: After laser intervention, patients usually recover faster, compared to traditional surgical methods.
  4. 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.
