Retinal laser photocoagulation
Laser photocoagulation of the retina is applied in case of peripheral and central dystrophies of the retina, vascular affections, and some types of tumors. Laser photocoagulation of the retina stops the development of dystrophy and prevents retinal detachment. It is also effective in prevention of progressing changes in the eye fundus.
This type of treatment has no alternative as far as the following disorders are concerned: changes on the retina, “latticed” degeneration of the retina, “snail trace” dystrophy, vascular disorders of the eyes, e.g. diabetic changes on the retina associated with diabetes mellitus, thrombosis of the central vein of the retina, angiomatosis, age-related macular dystrophy, vascular pathology of the veins (diabetic retinopathy, thrombosis, etc.).
Laser photocoagulation of the retina is performed on an out-patient basis with the application of local drop anaesthesia which is easily tolerated by patients of different age groups. It does not exert heavy loads on the heart, vessels and other organs.Laser photocoagulation of the retina takes between 15 and 20 minutes. After a short rest and examination by the doctor, the patient returns home and keeps to the daily routine.
The treatment principle is based on the laser impact which results in sharp increase of the temperature and provokes coagulation of the tissue. This makes surgery a bloodless operation. The laser is an extremely precise instrument and is used to ensure an attachment of the retina to the uvea (i.e. consolidation of the retina). For the procedure a special lens with an antireflecting coating is placed onto the eye of the patient. This lens allows laser rays to fully penetrate into the eye. Laser light is transferred through special light guides and this enables the surgeon to control the course of the operation through a stereomicroscope, aim and focus the laser beam.
The advantages of laser photocoagulation
- The consolidation of the retina by laser allows to avoid opening of the eye bulb; the operation is non-contact which excludes any infection.
- Thanks to special features of laser treatment, it is a bloodless operation.
- This method of treatment does not require general anaesthesia, resulting in less stress on the organism.
- Laser treatment is an out-patient procedure and there is no rehabilitation period.
