Abstract Details



Purpose:

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.

Setting:

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

Methods:

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.

Results:

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.

Conclusions:

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%.
