[Semiconducting lasers for the treatment of vascular retinopathy].

Clinical photocoagulation was performed successfully in 18 eyes with retinal vascular disease. In all cases semiconductor laser was used emitting wave lengths from 780 to 840 nm. Energy for visible coagulation edema was 400 up to 1,200 mW, time between 0.2 and 1 s. In 3 cases using endolaser, acute retinal traction during light exposition was seen; retinal hemorrhages occurred in no patient. Four patients complained of moderate to marked pain compared to argon laser treatment. In all cases visible marked retinal scars of therapeutical range were observed.
