Material and methods. The study included 16 patients (31 eyes). Types and terms of treatment. Stage I in the treatment of ROP, laser coagulation of the avascular areas of the retina was performed in three patients with aggressive posterior ROP (4 eyes, 12.9%). In all patients, the progression of the disease was noted. Intravitreal injection of ranibizumab was performed in the period from 8 to 16 weeks (10.5±2.0 weeks), PCV from 32.3 to 39.6 weeks (37.0±1.8 weeks). Result. After laser treatment and IVI of ranibizumab, 11 patients (31 eyes, 81.6%) showed regression of the disease. In 5 patients (6 eyes, 19.4%) - progression. If the ROP progressed, a 25G or 27G lenssparing vitrectomy was performed. Complete regression of ROP was achieved in one patient (1 eye, 16.7%). Partial regression was observed in two patients (2 eyes, 33.3%). In two patients (3 eyes, 50%), the disease progressed to stage 5 with the development of total retinal detachment. Conclusion. As a result of the complex treatment of severe forms of the active stage of retinopathy of prematurity in the regional children's ophthalmological center MKMC "Bonum" in Yekaterinburg, the following data were obtained: complete regression with retinal adhesion is observed in 12 patients (26 eyes, 83.4%), of which in one patient (1 eye, 3.2%) regression was achieved after vitrectomy. Partial regression with the formation of a peripheral retinal detachment after vitrectomy was achieved in two patients (two eyes - 6.5%). Progression of retinopathy of prematurity to stage V with the development of total retinal detachment in two patients (3 eyes, 9.6%). Complex treatment of severe stages of active ROP using laser treatment, IVI and vitrectomy allows to preserve vision in 90.4% of patients. Key words: retinopathy of prematurity; intravitreal injection; laser coagulation of the retina; vitrectomy.

Purpose.Analysis of visual functions in children in remote postoperative period after laser coagulation (LC) of threshold stages of retinopathy of prematurity (ROP).Patients and methods. In 2017, we selected and investigated 18 children, who previously had an LC of threshold stages of ROP in 2008–2009 in the Khabarovsk branch of the S.N. Fyodorov State Institution Eye Microsurgery Complex (continuous sampling method). There were 5 boys and 13 girls aged from 8 to 9 years at the time of LC. Anterior and posterior eye segments of the eyes (biomicroscopy, ophthalmoscopy), visual acuity, clinical refraction, concomitant pathology were evaluated.Results. We have revealed that regressive ROP after LC is characterized by the presence of serious anatomical and functional changes in the eyes. First, these are refractive disorders, which revealed in 90.5% of cases. Most often revealed: myopic refraction — 61% of all cases, of which more than half (53%) is its high degree; or its combination with compound myopic astigmatism (77% eyes); anisometropia was detected in 39% children. These refractive disorders led to the development of strabismus (61% children) and mixed amblyopia (60%). Despite the combined ophthalmologic pathology, 17% children developed visual functions with achievement of binocular vision, in most children visual functions still continue to develop, although they are not high due to amblyopia. High visual acuity (from 0.8 and above) in both eyes was formed in 22% children; visual acuity in the range of 0.5–0.7 in both eyes was formed in 17% children. Unfortunately, 44.5% children at the time of examination had low visual functions (in the range of 0.05–0.4) in both eyes. Extremely low visual acuity (from 0.01 to 0.04) in both eyes was identified in 11% children; absolute blindness in one of the eyes was in 11% children.Conclusions. LC is reliable way to prevent vision loss from retinal detachment in children with threshold stages of ROP.

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.

Insufficient effectiveness of laser coagulation of the avascular retinal areas in retinopathy of prematurity (ROP) plus-disease in zone I and aggressive posterior retinopathy of prematurity (APROP) requires new treatment approaches, based on the regulation of retinal angiogenesis and anti-VEGF drugs use. The BEAT-RAP study, which was the first major randomized study of anti-VEGF therapy in ROP, revealed a higher effectiveness of bevacizumab compared to retinal laser coagulation in stage 3 plus-disease of zone I. A prospective randomized trial, RAINBOW, demonstrated the effectiveness of ranibizumab in plus-disease stages 1, 2 and 3 in zone I and stage 3 in zone II and in APROP, so that the drug may be recommended for use in children with ROP. The demonstrated high effect of anti-VEGF therapy in ROP is consistent with our own data. Anti-VEGF therapy opens up new possibilities in the treatment of a particular class of ROP forms. The advantages of anti-VEGF therapy include higher clinical effectiveness of treatment of ROP type I with localization in the posterior pole (I and posterior II zone), absence of "blockage" of the peripheral retina, lower frequency of myopia development and degree, relative fastness of the procedure, the acceptability for patients whose fundus is difficult to visualize, and somatically burdened patients who are contraindicated for prolonged anesthesia used for retinal laser coagulation. When using anti-VEGF drugs in the post-threshold stages of the disease, one should take account of an increased risk of proliferation progression and retinal detachment development. Premature infants with retinopathy regression after anti-VEGF therapy require a longer duration of regular and frequent follow-up (up to 70 weeks of postmenstrual age) due to the risk of relapse and extraretinal proliferation in future.

The clinical course of active retinopathy after anti-VEGF therapy, the possibility and timing of recurrence of the disease, anatomical and functional outcomes of treatment are widely discussed in the press, not fully studied and relevant.Purpose: to study the clinical course of active retinopathy of prematurity after anti-VEGF therapy and clinical and functional outcomes.Patients and Methods. Children with active retinopathy of prematurity, who turned to the Helmgoltz National Medical Research Centre of Eye Diseases after anti-VEGF therapy, examined by indirect binocular ophthalmoscopy and digital retinal camera (RetcamShuttle). Children were monitored from 1.5 to 6 years (average 2.94 ± 1.47). All children underwent routine examination, 4 children older than 3 years underwent optical coherence tomography.Results. In all cases, after anti-VEGF therapy, there was a decrease in vascular activity and continued vascularization of the retina. Recurrence of the disease requiring additional treatment, were detected in 11 (42.3 %) eyes within 6–22 weeks (in average 13.33 ± 5.57) after intravitreal anti-VEGF therapy. Laser coagulation of the retina was carried out in 4 children (7 eyes) and repeated administration of anti-VEGF drug — 2 children (4 eyes), which led to regression of the disease. In the long-term period, all 13 (100 %) children had successful outcomes.Conclusion. Anti-VEGF therapy is effective in plus-zone 1 disease and posterior aggressive retinopathy of prematurity. Its advantages include the ability to treat retinopathy in zone 1 posterior, the absence of “blockade” of the peripheral retina with the possibility of continued growth of blood vessels to the periphery, lower frequency and severity of myopia. The disadvantages include the possibility of recurrence of the disease, which requires long-term regular monitoring.

Introduction: Retinopathy of prematurity is a leading cause of potentially avertable childhood blindness around the world. And laser photocoagulation is currently performed as a gold standard for retinopathy of prematurity treatment, but it may contribute to elevated myopia and decreased visual field. Therefore, the objective of this meta-analysis is to explore the negative impact of laser photocoagulation for retinopathy of prematurity in terms of anatomic outcomes and structural outcomes. Methods: Studies were retrieved through literature searches in PubMed and EMBASE from 1990 to 2017 in English. Case-control studies that reported anatomic and structural changes or significant complications after laser coagulation or cryotherapy for retinopathy of prematurity were eligible. Results: This meta-analysis included eight original studies related to laser treatment for retinopathy of prematurity at any stages. A total of 1422 infants were participated, of which 1156 documented subthreshold or threshold retinopathy of prematurity without laser treatment were selected as comparison group and the rest treated with diode or argon laser coagulation were chosen for experiment group. Taking all included studies into account, spherical equivalent (mean difference −2.53, 95% confidence interval: –5.23 to 0.18, I2 = 96%, P < 0.00001), anterior chamber depth (mean difference −0.52, 95% confidence interval: −0.76 to −0.28, I2 = 55%, P = 0.11), astigmatism (odds ratio 3.19, 95% confidence interval: 1.61 to 6.32, I2 = 0%, P = 0.54), and myopia (odds ratio 8.08, 95% confidence interval: 3.79 to 17.23, I2 = 37%, P = 0.21) were associated with laser treatment for retinopathy of prematurity. Axial length (mean difference −0.01, 95% confidence interval: –0.28 to 0.27, I2 = 0%, P = 0.62) and anisometropia (odds ratio 4.21, 95% confidence interval: 0.54 to 33.17, I2 = 1%, P = 0.31) had no statistical significance on laser coagulation for retinopathy of prematurity. Conclusion: This meta-analysis showed that spherical equivalent, anterior chamber depth, astigmatism, and myopia were associated with the negative outcomes of laser coagulation, while axial length and anisometropia had no statistical importance on the defects of laser coagulation. Therefore, patients treated with laser coagulation should follow periodic cycloplegic refraction and receive early optical correction.

AIM: To conduct a retrospective study of the application of vessel endothelium growth factor inhibitor ranibizumab in complex therapy of retinopathy of prematurity in Ural State children`s ophthalmological center at State Autonomic Health Institution of the Sverdlovsk Region Multiprofile Clinical Medical Center BONUM in Yekaterinburg. MATERIAL AND METHODS: The study included 17 patients (33 eyes). The gestation age was from 23 to 30 weeks (mean: 26.51.7 weeks), birth weight was from 600 to 1850 g (mean: 867229 g). 8 patients (47%) had APROP, and 9 patients (53%) had ROP stage III, type 1, plus disease. Laser coagulation of the avascular areas of the retina as the start in ROP therapy was performed in three patients with APROP (4 eyes, 12.1%). Intravitreal injection of the anti-VEGF ranibizumab was performed in 17 patients (33 eyes), including patients with previous laser coagulation. The age of the patients at the time of injection was from 7.7 to 15.6 weeks (10.51.9 weeks), PCA from 32.3 to 39.6 weeks (37.01.8 weeks). Patients with stage IVa ROP (5 patients, 6 eyes) underwent 25G or 27G lens sparing vitrectomy. RESULTS: As a result of the complex treatment of ROP, the following results were obtained: complete regression in 13 patients (28 eyes, 84.8%). Partial regression in two patients (2 eyes, 6.1%). ROP progression to stage V in two patients (3 eyes, 9.1%). CONCLUSION: Complex treatment of severe stages of active ROP with laser treatment, IVI injections, ranibizumab, and vitrectomy made it possible to preserve vision in 90.9% of patients.

Purpose. To study the effect of bright sunlight on immature retina of a premature baby at different periods of solar activity.Material and methods. The study involved two groups of premature babies: 32 babies (64 eyes) in 2016 and 50 babies (100 eyes) in 2017. Both groups were tested using a retinal camera (RetCam Shuttle, USA) on the 3rd or 4th week after birth. In cases of threshold stages of retinopathy of prematurity (ROP) binocular ophthalmoscopy were performed. In such cases, laser coagulation of the retina was performed using "ALOD 01" (ALCOM Medica, Russia).Results. The greatest number of ROP with the greatest number of surgical interventions and adverse outcomes that required vitreoretinal surgery were revealed in the second seasonal period (May — August), which experienced the highest solar activity. In 2016, the amount of ROP cases diagnosed in this period amounted to 59 %, which is comparable with the corresponding amount revealed in 2017 (61.1 %).Conclusions. Stronger solar activity and its longer periods increase the risk of ROP; consequently, to prevent this pathology, the eyes of the newborn should be protected from the negative effects of daylight and artificial light, including that emitted by diagnostic equipment.

Purpose: Analysis and prognostic outcomes of retinopathy of prematurity (ROP) depending on the solar activity at birth time and gestational age. Material and methods. 229 case histories of premature babies born within 2017-2019 were randomly selected. They were split into two groups: group I – children with ROP (1, 2 and 3 degree) and group II – without any ROP (pre retinopathy). The disease outcome was taken into account in the children with ROP: laser coagulation (LC) and spontaneous regression. Also, all children were split according to the seasons of birth: winter, spring, summer and autumn. Results. The seasonal differences in retinopathy outcomes were observed: in children born in spring and summer, the percentage of spontaneous regression was much lower and was 15% in spring, 13.2% in summer, 29% in autumn and 29.6% in winter. The percentage of performed LC on the contrary was 21.7%-28.3% in spring and summer period and 9.7%-14.8% in autumn and winter. Conclusion. A mathematical model is constructed for predicting the outcome of retinopathy of prematurity, determining the probability of spontaneous regression of the disease based on such independent variables as the level of insolation and the gestational age of the child. According to the obtained formula, the probability of spontaneous regression of retinopathy increases with an increase in gestational age and a decrease in solar activity at birth time. On the contrary, the probability of need for laser coagulation increases with a decrease in gestational age and an increase in the insolation intensity.
