Abstract Details


Studying of features of carrying out laser coagulation of a retina at aggressive posterior retinopathy of prematurity (ROP) and an assessment of its clinical efficiency.


The Khabarovsk branch of the State Institution Eye Microsurgery Complex named after S.N. Fyodorov, Khabarovsk, Russia


From only 2008 to 2013 it was carried out 331 retinal laser coagulation (RLC) at ROP (151 babies). Aggressive posterior retinopathy of prematurity took place in 61 children – 120 eyes (40.3%). The gestational age at the time of treatment made 34-42 weeks. Laser operations were carried out in specially adapted operating room, located in the anesthesiology block. Operations were carried out under a mask anesthesia with ftorotan solution. To all children RLC was carried out by means of the argon laser “Coherent Radiation” the Novus-2000 model (USA). At this time from 960 to 2500 coagulates were executed. The vast majority of RLC were carried out transpupillary by means of contact lenses, in 3 children (5 eyes) we applied the laser indirect ophtalmoscope for retinal coagulation.


Criterion of efficiency of performance of RLC was regress of the disease: lack of a retinal detachment, decrease in exudative and hemorrhagic activity, return development of a neovascularization of a retina, and also normalization of caliber and course of retinal vessels. Efficiency of laser coagulation of aggressive posterior retinopathy of prematurity was much lower, than at a threshold 3rd stage of a retinopathy. In 21.5% of cases in 2-4 weeks after primary operation an additional RLC was required. As a rule, additional retinal coagulation was carried out in a nasal hemisphere of an eye-ground that was caused by difficulty of access to this zone at primary laser surgery.


Aggressive posterior retinopathy of prematurity meets according to our data in 40.3% of prematurely born children. Retinal laser coagulation is the most available and widespread method of treatment of aggressive posterior ROP, however its efficiency doesn't exceed 59%.
