[Laser instrument surgery in preventing and treating retinal detachment (communication II)]

The paper is devoted to the actual problem of ophthalmology--removal of cysts and retinal detachments caused by cystoid retinal lesions. 3 stages of treatment are identified: stage 1 used YAG-laser dissection of the external wall of the retinal cyst with drainage of its contents. Stage 2 involved extrascleral filling reinforced by argon coagulation of the zone of the emptied cyst or by endolaser coagulation. Laser intervention was performed by the laser combine "Visulas-YAG II" produced by the firm "Karl Zeiss" (Germany) and fitted up by endolaser output. Coagulation energy was 0.2-0.7 W, the power of YAG-laser was 0.1-5.7 mJ with impulses of 120. Almost in all of the cases laser action was realized during one session. The laser's action was associated with hemorrhage in 11 cases (57.9%), and within 1 year of observations 2 relapses were noted (10.5%). YAG perforation of the external wall of a retinal cyst brings on its drainage and evacuation that is a perspective factor in subsequent surgical interventions during operations for retinal detachment due to cystoid degeneration.
