Abstract Details

Purpose:

Retinopathy of prematurity (ROP) is a major cause of childhood blindness and visual impairment worldwide. More than 17000 children are born each year in the Khabarovsk Territory (Russia), which is 8-10% more than in previous years. In 2008 In the clinical practice of our clinic a uniform protocol of care was introduced for premature children with the risk of ROP developing, approved by Ministry of Health of the Khabarovsk Territory. We analyzed the cases of retinal detachment in a remote, scarring period of ROP in children who previously received laser treatment for retinopathy of prematurity of threshold stage.

Setting:

State Institution Eye Microsurgery Complex named after S.N. Fyodorov, Khabarovsk, Russia

Methods:

The main method of treatment of threshold ROP stages in our clinic – transpupillary laser coagulation (LC) of avascular retina zones. By the method of continuous sampling we selected 135 medical records of children (245 eyes) who underwent LC at the threshold stage of ROP (2008-2012), and analyzed the long-term results of retinal laser coagulation.

Results:

In all eyes LC was performed without complications. At the end of the active period (post-conceptual age 40-42 weeks with a typical course and 55 weeks at the back aggressive form of ROP) induced regression was achieved in 213 eyes (86.9% of cases). Regression results in a reduction of vazo-proliferation, completion of retinal vascularization, exhaustion of defective newly formed blood vessels, normalizing of the caliber and route of retinal vessels, and absence of retinal detachment. In 32 eyes (13.1%) in the active period we noted progression of retinopathy of prematurity as a development of vitreoretinal stretches, up to the stage of retinal detachment, which required early surgery.

Conclusions:

Retinal detachment after LC developed in 13.1% of cases, wherein 2/3 of the cases – in the active stage of the disease, and in 1/3 of the cases – in the first 6-12 months after LC. Late retinal detachment occurred in two children 5 and 6 years after the LC.
