Аnatomical and functional features of eyes in children with the second stage of cicatricial retinopathy of prematurity after laser coagulation

Purpose. To evaluate anatomical and functional features of eyes in children with the 2nd stage of cicatricial retinopathy of prematurity (ROP) in long-term period after underwent laser coagulation (LC) of threshold stages of ROP. Material and methods. 18 children with the 2nd stage of cicatricial ROP, who in 2008–2009 underwent LC of retina of threshold stages of ROP (the main group). Selection criterion is absence of traction changes in macular area. In patients aged 8–9 years we studied visual evoked potentials (VEP), performed optical coherence tomography in macular area, and ocular biometry. The control was healthy children of similar age. Results. In the main group we revealed: statistically significant differences in increase of foveal thickness; tendency to reduction of retinal thickness in all segments of macular area; in 89% of cases pathological changes were observed in VEP, despite visually intact optic disc and macula. Conclusion. The features of eyes in children with 2nd stage of cicatricial ROP who underwent LC of retina of threshold stages of ROP, were: increase retinal thickness in fovea, uniform decrease in retinal thickness in other sectors in macular area, more smaller anterior chamber of the eye and narrow anterior chamber angle, than healthy peers. Key words: cicatricial retinopathy of prematurity, retinal thickness, anterior chamber of the eye, visual evoked potentials.
