[Pattern retinal laser coagulation in treatment of aggressive posterior retinopathy of prematurity].

Efficacy of pattern scanning laser coagulation in treatment of aggressive posterior retinopathy of prematurity (ROP) was evaluated. 25 premature neonates (50 eyes) with aggressive posterior ROP were examined and divided into two groups. 13 infants (26 eyes) of the 1st group underwent pattern laser coagulation performed using automanual scanning laser ophthalmologic coagulator. In the 2nd group diod laser coagulation was performed using conventional "point-by-point" technique in 12 infants (24 eyes). Post OP follow-up was 3-6 months. The average duration of laser coagulation session was 15 min in the 1st and 40 min in the 2nd group. The pattern of clinical regression was similar in both groups. In the Ist group stationary regression of aggressive posterior ROP was achieved in 77% patients. The clinical efficacy of treatment in the 2nd group was 71%. Pattern scanning laser coagulation in treatment of aggressive posterior ROP significantly allows to reduce duration of treatment session and narcosis of premature infant, improve efficacy and safety of laser procedure.
