Objective: to assess features of eyeball structure in children with the 2nd stage of cicatricial retinopathy of long-term prematurity (RP) after laser coagulation (LC).
Methods: We selected 18 children with the 2nd stage of cicatricial RP who underwent LC of retina in border stages of RP in 2008–2009 (main group). Selection criterion – absence of traction changes in macular area. Before the surgery they were 25– 33 weeks old, body weight 877–1800 g. We performed optical coherence tomography of macular area, determined the size of anteroposterior axis (APA) and the depth of anterior chamber of the eye in 2017. Control: group of 17 children of similar age with dysbinocular amblyopia. Analyzing the material, we used methods of descriptive statistics with calculation of average and its standard deviations.
Results: We detected a significant difference in depth of anterior chamber of the eye in representatives of the main group (2,38±0,19 mm) and of control group (2,78±0,18 mm). We determined general tendency to reduction of retinal thickness in all segments of macular area in children after LC, with a statistically significant difference being obtained in the inner temporal and inner upper segments. Exception to the general tendency was increase of retinal thickness in the foveolar fossa: 279,5±17,9 against 239,2±9,2 μm in control group.
Conclusions: Features of eyeball structure in children with the 2nd stage of cicatricial RP having undergone laser surgery are an increase in retinal thickness in the foveolar fossa and a uniform decrease in its thickness in other sectors of the macula, as well as a smaller anterior chamber of the eye compared with the benchmarks.
