What is photocoagulation?
Photocoagulation is a type of laser surgery that is used to treat the retina department. This treatment involves the use of an argon laser, which converts a high -intensity light beam that seals tears in the retina tissue. Laser treatment can also prevent the growth of abnormal blood vessels, which is a common side effect of retinal separation. Photocoagulation for the treatment of separate retina may prevent further loss of vision and abnormalities of the retina.
There are three main types of retinal department. The first, rhegmatogenic ward, develops because of age because the liquid sloping body in the middle of the eye reduces how ages. This can cause the retina to separate from the disciplinary body, causing visual impairment.
The second type is called the traction department of the retina. In addition, it is common in people with diabetes due to inflammation mediated by glucose combined with poor circulation. The third type of retina department is called an exudative connection and is the result of a liquid accumulation between the retina and choriDEM, a structure that is located under the retina. When the fluid accumulates, it can cause the retina disconnection. This type of separation is usually caused by cancer or inflammatory disorders.
Photocoagulation can be used as treatment for all three types of retinal departments. Argon laser is used in this type of treatment. This laser closely focuses the beam of light, which is then directed to a part of a separate retina at the rear of the eye. The beam of light is focused on a specific location where the retina is separated. When the light beam reaches the retina, the light is absorbed by cells and then converted to thermal energy. Healing seals a separate retina. This treatment usually takes thirty minutes or less.
When preparing for the treatment of photocoagulation, the patient is given eye drops to the NUMB eye and expand the pupil. The treatment is generally painless, but eye drops are necessary because some patients are sensitive to laser light.Once treatment is over, the patient may leave immediately. It should keep the eye covered for several hours due to increased sensitivity to light. In addition, the patient should provide transport of houses because the medicines given before treatment can reduce the driving ability.
Photocoagulant therapy is associated with few risks and this type of treatment is generally more successful than other treatment for retinal separation. Most separate retina may be successfully treated with one laser therapy session, but in some cases a second session may be required. Successful treatment will improve the patient's vision within six months of the procedure.
