Disruption of CD73-Derived and Equilibrative Nucleoside Transporter 1-Mediated Adenosine Signaling Exacerbates Oxygen-Induced Retinopathy. THE AMERICAN JOURNAL OF PATHOLOGY 2022; 192:1633-1646.

Abstract
Retinopathy of prematurity (ROP) is characterized by pathologic angiogenesis in retina, and remains a leading cause of blindness in children. Although enhanced extracellular adenosine is markedly increased in response to retinal hypoxia, adenosine acting at the A1 and A2A receptors has the opposite effect on pathologic angiogenesis. Herein, the oxygen-induced retinopathy (OIR) model of ROP was used to demonstrate that pharmacologic and genetic inactivation of CD73 (the key 5'-ectonucleotidase for extracellular generation of adenosine) did not affect normal retinal vasculature development but exacerbated intravitreal neovascularization at postnatal day (P) 17 and delayed revascularization at P21 of OIR. This exacerbated damage to retinal vessels by CD73 inactivation was associated with increased cellular apoptosis and microglial activation but decreased astrocyte function at P17 of OIR. Furthermore, pharmacologic blockade of equilibrative nucleoside transporter 1/2 (ENT1/2; bidirectional transport for controlling the balance of intracellular and extracellular adenosine) by 6-nitrobenzylthioinosine aggravated pathologic angiogenesis at P17 of OIR. Pharmacologic blockade of ENT1/2 and genetic inactivation of CD73 also aggravated avascular areas at the hyperoxia phase (P12) of OIR. Thus, disruption of CD73-derived extracellular adenosine or ENT1/2-mediated transport of adenosine flux across membrane aggravated the damage to retinal vessels. These findings support the role of adenosine as an endogenous protective regulator that limits oxygen-induced retinopathy. Thus, enhancing extracellular adenosine signaling represents a novel neuroprotection strategy for ROP by targeting CD73 and ENT1/2 activities.

Abstract
PURPOSE This study investigated the outcomes of vitrectomy for stage 5 retinopathy of prematurity (ROP) based on the International Classification of Retinopathy of Prematurity 3rd edition (ICROP 3), in which stage 5 ROP is divided into three subgroups. METHODS Fifty-four eyes of 34 patients with stage 5 ROP who underwent vitrectomy between 2004 and 2020 were retrospectively analyzed. Data including sex, gestational age and weight at birth, ICROP 3 subcategories, perioperative use of intravitreal bevacizumab injection (IVB) and laser photocoagulation, surgical procedure and complications, final retinal reattachment, and follow-up period were collected. RESULTS Complete retinal reattachment was achieved in 16 eyes (88.9%) with stage 5A and 13 eyes (39.4%) with stage 5B (P = 0.0003, Wilcoxon rank-sum test). Three patients with stage 5C were considered inoperable. Postoperative anatomical failure was significantly associated with stage (stage 5B vs. 5A; odds ratio, 17.986; 95% confidence interval, 3.712-148.502; P = 0.0001, multivariate logistic regression analysis). Intraoperative IVB was significantly associated with lower postoperative incidence of vitreous hemorrhage and glaucoma (P = 0.041, chi-square test). CONCLUSIONS Staging of preoperative anatomical features based on ICROP 3 is a useful predictor for final anatomical success. Intraoperative IVB might reduce postoperative complication risks.

Abstract
Aims To describe the long-term effect of scleral buckling (SB) surgery for stage 4A retinopathy of prematurity (ROP). Methods A retrospective chart review was conducted for patients with a diagnosis of stage 4A ROP who underwent SB between October 2010 and October 2021. Basic data were collected from patient charts, including gender, birth weight, gestational age at birth, disease stage, presence of plus disease, preoperative treatment [laser photocoagulation, intravitreal anti-vascular endothelial growth factor (VEGF) agent therapy, or a combination of both] and complications (vitreous hemorrhages), postmenstrual age at surgery, intraoperative combined treatment, and total length of follow-up. Retinal attachment status after surgery, postoperative complications (glaucoma, cataract), date and type of subsequent retinal surgeries (if performed), and refractive status 1 year after surgery were evaluated. The follow-up time after the first procedure was over 1 year. Results Six-two eyes from forty-eight patients met the inclusion criteria for this study. The initial reattachment rate was 93.5% (58/62 eyes), and the final reattachment rate was 100% after two procedures at the end of follow-up. The incidence of cataracts was 3.2% (2/62), with no eye subsequently needing lensectomy surgery. None of the patients developed glaucoma during the follow-up time. The average spherical equivalent refraction value for patients was −3.00 ± 2.51 D (−7.60 D to +2.75 D) 1 year after surgery. Conclusion SB, especially segmental buckling, which induces less myopia and does not require buckle removal, has the potential to provide a significant positive impact in the treatment of stage 4A ROP.

Abstract
Purpose To report a modified technique of dry-lensectomy assisted lensectomy in the management of end-stage familial exudative vitreoretinopathy (FEVR) complicated with capsule-endothelial, iris-endothelial adhesion and secondary glaucoma. Methods 24 eyes of 16 patients with severe complications of advanced pediatric total retinal detachment caused by FEVR who received limbus-based dry-lensectomy were studied retrospectively. Preoperative and postoperative clinical information was collected and reviewed. Results Among the 24 eyes, three eyes (12.50%) underwent lensectomy combined with vitrectomy and membrane peeling simultaneously. 21 (87.50%) eyes underwent lensectomy without membrane peeling due to severe corneal opacity or retinal vascular activity, of which eight underwent another vitrectomy combined with membrane peeling. At the last visit (mean:13.86 ± 5.24 months of follow-up), all eyes had a reconstructed anterior chamber with normal depth. Among 21 eyes having preoperative corneal opacity, 15 (71.43%) had a clearer cornea with reduced opacity, 5 (23.81%) showed similar corneal opacification without deterioration. Among 11 eyes undergone retrolental fibroplasia peeling, seven (63.64%) eyes showed partial retinal reattachment in open-funnel type. Conclusion Dry-lensectomy offered a simple way to lower the intraocular pressure and simplified the surgery, which helped to solve the severe anterior segment complications and offer a chance for following retrolental fibroplasia peeling and potential visual gain for selected end-stage FEVR patients.

Abstract
Aim of the Work To evaluate the incidence and risk factors for development of retinopathy of prematurity (ROP) in the biggest neonatal intensive care unit (NICU) in Itay Elbaroud City, Behera province, Egypt. Methods We studied data of 240 newly born infants with gestational age (GA) ≤34 weeks or birth weight (BW) ≤2000 g or infants with unstable course who were admitted to the biggest NICU in Itay Elbaroud City, Behera province, Egypt,
between October 1, 2018 and October 31, 2020. There is no standard screening system in Egypt. Furthermore, we had screened babies more than 1500 g, more than 32 weeks and found signs of ROP, so we decided to expand our inclusion criteria to include babies up to 2000 g of birth weight and up to 34 weeks gestational age in addition to older and heavier babies with unstable course in NICUs. Clinical information about perinatal neonates was collected by reviewing medical charts. The main outcomes are the incidence and severity of ROP. The relationship of clinical risk factors and the development of ROP were analyzed. Results The overall incidence of ROP was 34.1%, and the overall incidence of type 1 ROP was 26.3% of infants. ROP was significantly associated with GA (odds ratio; OR: 6.8; (3.7–12.3), BW (OR: 4.1; 2.3–7.3), apnea, supplementary oxygen administration, and thrombocytopenia. Conclusion The incidence of ROP is high in Itay Elbaroud city, Behera Province, Egypt. Immaturity, low birth weight, low gestational age, oxygen administration, apnea, thrombocytopenia, and jaundice are important risk factors for development of ROP.

Abstract
PURPOSE To report anatomical and visual outcomes and potential prognostic factors with microincision vitrectomy surgery in Stage 5 retinopathy of prematurity. METHODS The medical records of premature babies who underwent microincision vitrectomy surgery for Stage 5 retinopathy of prematurity using 23G, 25G, or 27G instrumentation and had a minimum follow-up of 6 weeks were, retrospectively, analyzed. Primary outcome measures were anatomical success at last follow-up defined as retinal attachment at the posterior pole and visual outcomes. Potential risk factors and complications influencing anatomical outcomes were also analyzed. RESULTS One hundred seventy eyes of 115 infants underwent lensectomy and vitrectomy with microincision vitrectomy surgery. After a mean follow-up of 30.59 ± 33.24 weeks, anatomical success was achieved in 56 eyes (33.7%) of 166 eyes that had a minimum follow-up of 6 weeks. Occurrence of vitreous hemorrhage was more with 23 gauge (62.27%) as compared to 25 gauge (37.73%) (P = 0.024). With increase in age with each week, the probability of achieving anatomical success was found to be significantly more (odds ratio 1.030; confidence interval = 1.010-1.060; P = 0.008). Presence of anterior segment pathology was associated with poor anatomical outcomes (odds ratio 2.480; confidence interval = 1.190-5.160; P = 0.010). Seventeen children with attached retina had a follow-up of 14 months-5 years, of which ambulatory vision was recorded in five eyes and the ability to identify objects close to face in 12 eyes. CONCLUSION Although surgery for Stage 5 retinopathy of prematurity is challenging, anatomical success can be seen in one-third of cases with microincision vitrectomy surgery. Visual prognosis may be limited but still beneficial.

Abstract
Purpose: The purpose of this study is to describe the short-term incidence, clinical features, and management of glaucoma in children after successful surgery for stage 4 retinopathy of prematurity (ROP). Methods: The retrospective study included all eyes undergoing successful surgery for stage 4 ROP with good outcomes at a tertiary eye care center between June 2014 and June 2016. Cases developing postoperative glaucoma underwent examination under anesthesia for measurement of intraocular pressures (IOP), corneal diameters, Retcam-assisted fundus imaging, and gonioscopy. Outcomes of glaucoma management were evaluated. Results: Hundred eyes of 70 babies underwent successful surgery for stage 4 ROP (with postoperative attached retina, and minimal sequelae) with minimum follow-up of 15 months. Six eyes (6%) developed postoperative glaucoma. Of these, four eyes had undergone lens-sparing vitrectomy and two were managed with lensectomy and vitrectomy (LV). Median time duration for development of glaucoma after primary vitreous surgery was 17.5 weeks. Two cases could be managed with topical IOP-lowering agents alone, whereas four required filtering surgeries (trabeculotomy with trabeculectomy and 0.04% mitomycin C [MMC] application). Average IOP decreased from 25 ± 2.36 to 12.2 ± 2.05 mmHg at 12 months from glaucoma diagnosis. Conclusion: Glaucoma is a potential adverse event following successful vitreous surgery for stage 4 ROP. A combined trabeculotomy–trabeculectomy along with MMC gives favorable outcome.

Abstract
Introduction Retinopathy of prematurity (ROP) is a leading cause of childhood blindness worldwide. Areas covered Recent methods to identify and manage treatment-warranted vascularly active ROP are recognized and being compared to standard care by laser treatment in prospective large-scale clinical studies. Pharmacologic anti-angiogenic (anti-VEGF) treatment has changed the natural history of vascularly active ROP by reducing stage 3 intravitreal neovascularization and extending physiologic retinal vascularization in many infants. Tractional retinal detachments in stage 4 ROP after treatment with anti-VEGF agents show additional fibrovascular complexity compared to eyes treated with laser only. We review current management and outcomes for vascularly active and fibrovascular retinal detachment in ROP (stages 3, 4, 5 ROP), highlighting the evidence from recent clinical studies. Included are technical details important in surgery for retinal detachment in ROP. Literature searches were employed through PubMed. Expert opinion Methods in pediatric imaging, safer pharmacologic treatments, and surgical techniques continue to advance to improve future ROP outcomes.

Abstract
PurposeTo describe the long-term anatomical and functional results of surgery for retinal detachment (RD) associated with stage 4 retinopathy of prematurity (ROP) and patient and surgery-related factors affecting postoperative success.DesignRetrospective case series at a single tertiary referral paediatric vitreoretinal practice.MethodsOne hundred and twenty-one eyes of 82 infants (40 female/42 male) who underwent lens-sparing vitrectomy (LSV) or lensectomy with vitrectomy surgery for stage 4A and 4B ROP at Gazi University Department of Ophthalmology between 2011 and 2016 were enrolled in this study. Patient characteristics including gestational age, birth weight, gender, stage of ROP at presentation, preoperative treatment (laser, anti-vascular endothelial growth factor (VEGF) or combined), anatomical and functional outcome and complications were recorded. The effect of birth weight, gestational age, presence of plus disease, preoperative treatment status, surgically induced posterior hyaloid detachment, postoperative vitreous haemorrhage and iatrogenic retinal tear formation on anatomical and functional results was evaluated.Results61.2% of the eyes were stage 4A and 38.8% were stage 4B ROP. The mean follow-up was 24.5 months. 18.2% of the eyes had no preoperative treatment. Anatomical success was 86.5% for stage 4A and 68.1% for stage 4B at the first year, 91.7% for stage 4A and 69.4% for stage 4B at the second year, and 95.8% for stage 4A and 57.9% for stage 4B at the third year. Functional success was 85.1% for stage 4A and 65.9% for stage 4B at the first year, 89.6% for stage 4A and 61.1% for stage 4B at the second year, and 87.5% for stage 4A and 57.8% for stage 4B at the third year. The mean visual acuity was 1.12±0.34 logarithm of the minimum angle of resolution (logMAR) for stage 4A and 1.34±0.32 logMAR at the 3-year follow-up duration (p>0.05). There was preoperative plus disease in 59.5% of the eyes. Subsequent retinal surgeries were required in 17.4% of the eyes. Presence of plus disease and absence of preoperative treatment, iatrogenic retinal tear formation and postoperative vitreous haemorrhage were found to have significant negative effects, while surgical induction of posterior hyaloid detachment and sparing the lens intraoperatively affected the anatomical and functional results positively.ConclusionsSurgery for stage 4 ROP-associated RD resulted in encouraging anatomical and functional outcomes and the results are even better in eyes with preoperative (laser/anti-VEGF) treatment, LSV and surgically induced posterior hyaloid detachment.

Abstract
Retinopathy of prematurity (ROP) is one of the most common causes of preventable blindness in children. In spite of the availability of various treatment options, and favorable results with timely intervention, many infants present to the ophthalmologists in the advanced end stage of the disease due to lack of awareness especially in the developing nations. This blinding or Stage 5 of ROP presents with total retinal detachment and has to be managed surgically. The surgical techniques for Stage 5 ROP are unique and demanding. The successful anatomical results after surgery are only seen in 20%–50% of cases. In spite of a successful anatomical result, the visual outcome may be slow and limited. The use of newer pharmacological adjuncts has shown promising results. Because of heterogeneity of presentation of the disease severity, a genetic predisposition has also been proposed. A concerted effort from the pediatricians, ophthalmologists, and healthcare workers is required to establish effective screening and treatment guidelines to prevent blindness due to ROP. Till then surgical management has to be done. Parents must be educated regarding the limited visual benefits of surgery and the need for prolonged follow-up. This review gives a comprehensive overview of the pathogenesis, clinical aspects, surgical interventions, and their outcomes and future prospects of Stage 5 ROP.
