The aim of laser treatment is the creation of adhesionsbetween the retina and the underlying choroid. For this purpose, coalescers lasers, which cause the formation of local retinal mikroozhogov (lazerkoagulyatov).
Laser treatment is used
In order to prevent retinal detachment(Prophylactic laser photocoagulation). Laser coagulation is used for the delimitation of hazardous retinal dystrophies (especially "lattice" and "snail trail"). For their identification requires a thorough examination of the periphery of the fundus in a maximum mydriasis (dilated pupils at the maximum). Such a study should be carried out at least once in 6 months, in patients with an increased risk of retinal detachment (myopia, retinal detachment in the presence of the next of kin, transferred last surgery on the organ of vision and others.).
For the purpose of distinguishing the existing detachmentretina (therapeutic laser photocoagulation). As a rule, otgranichitelnaya laser photocoagulation can be applied in the case of a local flat retinal detachment, in cases where the conduct radical surgery for some reasons it is impossible (for example, in severe general condition of the patient).
In order to further coagulation of the rupture zone after surgery for retinal detachment.
Retinal laser photocoagulation procedure is carried out under thelocal anesthesia (after instillation of anesthetic solution). In the eyes set a special contact lens (Goldmann three-mirror lens), which allows to focus the laser light on any portion of the fundus.
Implementation of retinal laser photocoagulation
The rupture zone or local retinal detachment delimited several rows lazerkoagulyatov.
In order to form a solid chorioretinal adhesions (adhesions between the choroid and retina) takes time - about 10-14 days. The absence of progression of retinal detachment, it spread abroad coagulates serves as a basis to consider this a successful laser coagulation.
During the excessively "hard" laser photocoagulationlarge area of the retina zones may develop the following complications: exudative retinal detachment, choroidal detachment (with proper treatment of these complications are resolved within a few days), degenerative changes in the macular region (maculopathy).
After a successful preventive laser coagulationnot less than 1 time in 6 months, and on doctor's advice, and often necessary to make routine inspection of the periphery of the fundus of both eyes with wide pupils for the emergence of new areas of retinal degeneration or the occurrence of thinning and retinal breaks in previously identified areas. Prophylactic laser photocoagulation such sites will allow several times to reduce the risk of retinal detachment and avoid the loss of visual function.
