Abstract
Background Stage 4 and 5 retinopathy of prematurity (ROP) is a serious condition that may require surgical intervention at some point. Timely intervention is a key element and, with the peculiarity of eyes among this group that necessities a certain level of surgical standards, operations cannot be undertaken in any surgical eye center. Aim of the Study To recognize the outcomes of vitrectomy in Iraqi preterm babies with stage 4 and 5 ROP, and to study factors that might increase the risk of re-detachment in operated eyes. Methods A prospective cohort study undertaken from November 2020 to June 2023 for Iraqi preterm babies presenting with stage 4 and 5 ROP requiring surgical intervention. Each patient had a follow-up duration of 9 months. The primary follow-up outcome was anatomical success rate (flat versus detached), and the secondary outcome was to identify the postoperative complications. Results This study enrolled 19 children; 11 males and eight females (number of eyes operated on was was 31), with a mean gestational age of 29.4±2.1 weeks. There were six (19.4%) eyes that did not develop any complications, five (16.1%) eyes developed postoperative vitreous hemorrhage, five (16.1%) eyes developed cataract, three (9.7%) eyes underwent a second vitrectomy, and seven (22.6%) eyes developed secondary glaucoma. The surgical success rates were 90.9% for stage 4a, 57.1% for stage 4b, and 33.3% for stage 5a. Conclusion This study presented the first surgical experience for vitrectomy in children with retinopathy of prematurity in our country, and the results were encouraging with an overall surgical success rate of 64.5%, and 19.4% of eyes did not develop any complication until the 1-year of follow-up.

[PMID: 37854031 PMCID: PMC10579817 DOI: 10.3389/fped.2023.1273413] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 09/22/2023] [Indexed: 10/20/2023] Open
Abstract
Background In order to understand the research hotspots and trends in the field of retinopathy of prematurity (ROP), our study analyzed the relevant publications from 2003 to 2022 by using bibliometric analysis. Methods The Citespace 6.2.R3 system was used to analyze the publications collected from the Web of Science Core Collection (WoSCC) database. Results In total, 4,957 publications were included in this study. From 2003 to 2022, the number of publications gradually increased and peaked in 2022. The United States was the country with the most publications, while Harvard University was the most productive institution. The top co-cited journal PEDIATRICS is published by the United States. Author analysis showed that Hellström A was the author with the most publications, while Good WV was the top co-cited author. The co-citation analysis of references showed seven major clusters: genetic polymorphism, neurodevelopmental outcome, threshold retinopathy, oxygen-induced retinopathy, low birth weight infant, prematurity diagnosis cluster and artificial intelligence (AI). For the citation burst analysis, there remained seven keywords in their burst phases until 2022, including ranibizumab, validation, trends, type 1 retinopathy, preterm, deep learning and artificial intelligence. Conclusion Intravitreal anti-vascular endothelial growth factor therapy and AI-assisted clinical decision-making were two major topics of ROP research, which may still be the research trends in the coming years.

International Classification of Retinopathy of Prematurity, Third Edition. Ophthalmology 2021; 128:e51-e68. [PMID: 34247850 PMCID: PMC10979521 DOI: 10.1016/j.ophtha.2021.05.031] [Citation(s) in RCA: 238] [Impact Index Per Article: 79.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 05/27/2021] [Accepted: 05/28/2021] [Indexed: 12/17/2022] Open
Abstract
PURPOSE The International Classification of Retinopathy of Prematurity is a consensus statement that creates a standard nomenclature for classification of retinopathy of prematurity (ROP). It was initially published in 1984, expanded in 1987, and revisited in 2005. This article presents a third revision, the International Classification of Retinopathy of Prematurity, Third Edition (ICROP3), which is now required because of challenges such as: (1) concerns about subjectivity in critical elements of disease classification; (2) innovations in ophthalmic imaging; (3) novel pharmacologic therapies (e.g., anti-vascular endothelial growth factor agents) with unique regression and reactivation features after treatment compared with ablative therapies; and (4) recognition that patterns of ROP in some regions of the world do not fit neatly into the current classification system. DESIGN Review of evidence-based literature, along with expert consensus opinion. PARTICIPANTS International ROP expert committee assembled in March 2019 representing 17 countries and comprising 14 pediatric ophthalmologists and 20 retinal specialists, as well as 12 women and 22 men. METHODS The committee was initially divided into 3 subcommittees-acute phase, regression or reactivation, and imaging-each of which used iterative videoconferences and an online message board to identify key challenges and approaches. Subsequently, the entire committee used iterative videoconferences, 2 in-person multiday meetings, and an online message board to develop consensus on classification. MAIN OUTCOME MEASURES Consensus statement. RESULTS The ICROP3 retains current definitions such as zone (location of disease), stage (appearance of disease at the avascular-vascular junction), and circumferential extent of disease. Major updates in the ICROP3 include refined classification metrics (e.g., posterior zone II, notch, subcategorization of stage 5, and recognition that a continuous spectrum of vascular abnormality exists from normal to plus disease). Updates also include the definition of aggressive ROP to replace aggressive-posterior ROP because of increasing recognition that aggressive disease may occur in larger preterm infants and beyond the posterior retina, particularly in regions of the world with limited resources. ROP regression and reactivation are described in detail, with additional description of long-term sequelae. CONCLUSIONS These principles may improve the quality and standardization of ROP care worldwide and may provide a foundation to improve research and clinical care.

Abstract
BACKGROUND Stage 5 retinopathy of prematurity is a difficult condition to treat despite technological advances in vitreous surgery. METHODS A retrospective chart review of all consecutive cases of stage 5 ROP was performed between December 2016 and December 2018, and 21 babies were included for assessment of surgical outcomes using a modified vitrectomy technique. Data extracted from documents included demography, ROP screening status, preoperative prophylactic therapy, clinical presentation, surgery performed, and postsurgical outcomes. RESULTS Out of the 21 babies, ophthalmologist screening was done in 42.9%. Mean birth weight was 1185 ± 222.4 g with a mean gestational age of 29.86 ± 2.0 weeks and mean post-menstrual age of 44.55 ± 9.82 weeks. Lesser than stage 5 disease was seen in 16.7% of eyes and they were managed accordingly. Seventy percent of babies had bilateral disease. 21 eyes underwent 25-gauge pars plicata vitrectomy using a modified technique. After an average follow-up duration of 6.33 ± 2.18 months, the final macular attachment rate was 19%. Anteriorly closed-posteriorly closed type configuration of retinal detachments had a poorer outcome. Fix and follow visual acuity was achieved in 23.8% of eyes, while 57.1% of eyes had a perception of light. CONCLUSIONS Management of stage 5 ROP is mostly surgical; however, the risk of ending up with a poor vision or vision loss is high, irrespective of whether surgery is performed. The modified surgical technique with a spacer described in this study may help in better manipulation of instruments inside the vitreous cavity.

Abstract
Retinopathy of prematurity (ROP) is a vasoproliferative disease of developing retinal vessels that affects premature infants and can lead to severe and irreversible visual loss if left untreated. India and some other Asian countries are in the middle of a 'third ROP epidemic'. Blindness due to ROP is largely preventable if appropriate, adequate and accessible screening programmes are available. Screening of the premature babies is the first step in ROP management. With the increase in use of tele-screening techniques, more premature babies have been brought under the screening network both from urban and rural regions. Laser photocoagulation to the avascular retina using indirect ophthalmoscopy delivery system is the gold standard for ROP treatment and is usually done under topical anaesthesia in the Asian region in contrast to the western world. Use of intravitreal anti-vascular endothelial growth factors (VEGF) although controversial in management of ROP has been found to be effective in various Asian studies as well. ROP surgery in India and other middle-income Asian countries is largely performed only in few tertiary eye care centres. Poor visual prognosis, late presentation with advanced retinal detachments, lack of adequate number of trained paediatric retinal surgeons and paediatric anaesthetists also contribute to this problem. This current paper summarizes the Asian experience of ROP management.

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
Background Severe retinopathy of prematurity (ROP) with extremely unfavorable prognosis among infants can do great damage to individuals and bring tremendous social-economic burden. The purpose of this study is to describe the demographic and ocular characteristics of infants who presented with stage 5 ROP in order to identify reasons why they have become blind, and to identify contributing factors in order to focus great attention on the current ROP program and to inspire more effort in ROP screening in middle income countries. Methods A retrospective review of consecutive infants with stage 5 ROP from December 2010 to December 2016 in Department of Ophthalmology, Xijing Hospital. Various parameters retrieved included birthweight, gestational age, age at initial examination, postmenstrual age, screening details, check-up details and reasons for consultation. Ocular findings were recorded and also detected by ultrasonography. Results A retrospective review of 20 consecutive infants with stage 5 ROP are included. Mean birthweight was1712.3 ± 512.97 g and mean gestational age at birth was 32.1 ± 2.21 weeks. Median age at first consultancy was 9.7 month. Median postmenstrual age first consultancy was 52 weeks. All infants were never screened for ROP before they came to the referral center. Of twenty stage 5 ROP infants, 13 cases presented with bilateral stage 5 features. Of the 40 eyes of 20 infants, 33 eyes were diagnosed as stage 5. Leukocoric pupil, closed funnel configuration of retinal detachment (RD), posterior synechia, extraretinal fibrovascular proliferation and retinal folds were the most significant indicators of bad prognosis. Ten eyes appeared no fixation to light, while 30 eyes exhibited following to light or following to toys. Conclusions Our study shows that in relatively less-developed regions of China, more needs to be done to spread awareness about the disease among pediatricians, neonatologists and ophthalmologists as well as parents of premature infants. Thus, a comprehensive control system which is a whole network of propaganda, screening, treatment and follow-up are encouraged especially in less developed areas in China as well as worldwide.

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.

Abstract
PURPOSE To determine incidence, risk factors, risk period, and characteristics of recurrent retinopathy of prematurity (ROP) treated by intravitreal bevacizumab (IVB) monotherapy. DESIGN Retrospective case series. PARTICIPANTS Premature infants with type 1 ROP (subdivided into stage 3+ ROP and aggressive posterior ROP [APROP]) in zone I or zone II posterior who received IVB monotherapy and were followed up for at least 65 weeks adjusted age (AA). METHODS Retrospective review of infants who demonstrated recurrence of type 1 ROP after IVB monotherapy, including examination of RetCam fundus photographs and fluorescein angiograms. MAIN OUTCOMES MEASURES Incidence, risk factors, risk period, and characteristics of recurrent ROP. RESULTS Intravitreal bevacizumab monotherapy in 241 infants (471 eyes) was reviewed. Recurrence incidence was 8.3% (20/241) for infants and 7.2% (34/471) for eyes. Recurrence risk factors of greatest significance were appearance of neovascularization as APROP (P = 0.006), extended duration of hospitalization (P = 0.01), and lower birth weight (P = 0.024). Recurrence risk period was between approximately 45 and 55 weeks AA (90.0% [18/20] for infants and 94.1% [32/34] for eyes), with mean recurrence of 51.2 weeks AA (±4.6 weeks; range, 45.7-64.9 weeks) and mean interval of 16.2 weeks (±4.4 weeks) between treatments. Recurrence characteristics included plus disease (20/20 infants [100%]) and neovascularization, which appeared at the following sites: stage 3+ ROP with confluent neovascularization recurred both at the advancing edge and at the initial ridge and extraretinal fibrovascular proliferative complex (12/14 infants [85.7%]). However, APROP (6/6 infants [100%]) and stage 3+ ROP with nonconfluent neovascularization (2/14 infants [14.3%]) recurred only at the advancing edge. Also, the anterior extent of retinal vascularization was decreased (mean, 1.76 disc diameters [DD] vs. 4.48 DD), and the rate of retinal vascularization was delayed (mean, 0.11 DD/week vs. 0.23 DD/week) in those with versus without recurrence, respectively. After retreatment with IVB, retinal vascularization proceeded minimally and slowly. CONCLUSIONS Premature children with severe ROP are being treated successfully with IVB monotherapy. However, recurrence is not uncommon, so vigilant follow-up is necessary to ensure timely re-treatment. Knowledge of recurrence incidence, risk factors, risk period, and characteristics allows for tailored clinical management.

Abstract
PURPOSE To determine the incidence and risk factors for delayed-onset intraocular pressure (IOP) elevations after vitrectomy for Stages 4 and 5 retinopathy of prematurity and, in addition, to determine the results of treating the IOP elevations. METHODS Fifty-five consecutive eyes with successful retinal reattachment and at least 24 months of follow-up after vitrectomy were studied. The ophthalmic examinations included slit-lamp biomicroscopy, wide-field digital retinal imaging, and IOP measurements. Eyes were classified into 2 groups: eyes with a postoperative IOP elevation to ≥ 21 mmHg and eyes whose IOP was always <21 mmHg. RESULTS Eight eyes (14.5%) developed an IOP elevation to ≥ 21 mmHg from 2 months to 4 months (median: 2.5 months) after the vitrectomy. In two of these eyes, the IOP was controlled with antiglaucoma medications. In the other six eyes, trabeculotomy for eyes with open angles and trabeculectomy or goniosynechialysis for eyes with closed angles were performed. The IOPs were successfully controlled after an average of 1.5 glaucoma surgeries. Multivariate logistic regression analyses identified that a young gestational age (odds ratio = 1.147, 95% confidence interval: 1.024-1.346) and lensectomy (odds ratio = 8.795, 95% confidence interval: 1.262-183.3) were significantly associated with the IOP elevation. CONCLUSION Delayed-onset IOP elevation after vitrectomy for retinopathy of prematurity occurs in 14.5% of the eyes, and it is significantly associated with a young gestational age and presence of lensectomy.

Abstract
Purpose To assess the long-term anatomic and visual outcomes and associated complications of lens-sparing vitrectomy (LSV) in infants with progressive posterior-type tractional retinal detachment (TRD) associated with stage 4A retinopathy of prematurity (ROP). Methods In a retrospective case series, the medical records of consecutive patients who presented with progressive posterior-type stage 4A ROP and underwent LSV between 1999 and 2007 were reviewed. Retinal attachment status, visual acuity, and development of postoperative complications were assessed. Results Eleven eyes of 9 patients were included. The mean follow-up period was 4.6 years. In 8 eyes (73%), plus disease was present at the time of LSV. In 3 eyes (27%), 2 (66%) without plus disease and 1 (13%) with plus disease, the retina remained reattached in the end, while 8 eyes (73%) had TRD on final examination. Two eyes with reattached retinas showed favorable visual acuity. In those eyes with detached retinas, 5 (68%) showed no light perception. When surgery for ROP was unsuccessful, development of cataract, corneal opacity, or glaucoma was common. Conclusions The long-term anatomic success rate of LSV for progressive posterior-type stage 4A ROP was low, especially in the presence of plus disease at the time of LSV. Anatomical reattachment is very important for preventing complications and gaining better visual outcomes.

Abstract
PURPOSE To assess long-term anatomic and visual outcomes and associated complications of lens-sparing vitrectomy (LSV) for treatment of tractional retinal detachments (TRDs) associated with stages 4B and 5 retinopathy of prematurity (ROP). METHODS We performed a retrospective review of medical records and data analyses of consecutive patients who presented with stages 4B and 5 ROP and underwent LSV from 1999 to 2007. Retinal reattachment status, visual acuity and postoperative complications were evaluated. RESULTS Twenty-one eyes of 20 patients, including 13 eyes with stage 4B ROP and 8 eyes with stage 5 ROP, were examined. The mean follow-up period was 5.6 years. In 9 (43%) out of 21 eyes, retinas were eventually reattached. The anatomic success rates were 62% in stage 4B and 13% in stage 5 ROP. In eyes with reattached retinas, visual acuity better than form vision was shown in 7 eyes (78%), whereas no light perception was present in 10 eyes (83%) among eyes with TRD on final examination. Postoperative intraocular hemorrhage occurred in nine eyes (43%). Long-term complications of cataract, corneal opacity, glaucoma and strabismus developed in 4 (19%), 6 (29%), 7 (33%) and 8 (38%) eyes, respectively, and were more common in eyes with TRD. CONCLUSIONS After following-up for a mean of 5.6 years, the anatomical success rate of LSV was encouraging for the correction of TRD associated with stage 4B ROP but not for stage 5 ROP. Retinal reattachment is important for obtaining better visual outcomes and preventing the development of late complications.
