Ophthalmic Physiol Opt 2023; 43:985-996. [PMID: 37340533 DOI: 10.1111/opo.13185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 05/18/2023] [Accepted: 06/01/2023] [Indexed: 06/22/2023]
Abstract
PURPOSE Controversy exists regarding the influence of peripheral visual experience on the onset and progression of childhood myopia. This longitudinal, observational study evaluated the relationship between relative peripheral refraction (RPR) and changes in refractive error and axial length (AL) over 12 months in White children aged 6-7 and 12-13 years with a range of baseline refractive errors. METHODS Cycloplegic baseline autorefraction at horizontal retinal eccentricities of 0° and ±30° were recorded with the Shin-Nippon NVision-K 5001 while AL was measured using the Zeiss IOLMaster 700. Measurements were repeated after 12 months on a subgroup. Refractive data were transposed into power vectors as mean spherical equivalent (M), J0 and J45 . RPR was calculated by subtracting central from peripheral measurements. Participants were defined as myopic (M ≤ -0.50 D), premyopic (-0.50 D < M ≤ +0.75 D), emmetropic (+0.75 D < M < +2.00 D) or hyperopic (M ≥ +2.00 D). RESULTS Data were collected from 222 and 245 participants aged 6-7 and 12-13 years, respectively. Myopic eyes demonstrated, on average, more hyperopic RPR. Emmetropes and premyopes displayed emmetropic RPR, and hyperopes showed a myopic RPR. Fifty-six 6- to 7-year-olds and seventy 12- to 13-year-olds contributed 12-month repeated measures. Longitudinal data demonstrated a significant relationship between a more hyperopic RPR in the nasal retina and greater short-term axial elongation in teens with myopia at baseline (β = 0.69; p = 0.04). Each dioptre of relative peripheral hyperopia in the nasal retina was associated with an additional 0.10 mm (95% CI: 0.02-0.18 mm) annual increase in AL. CONCLUSIONS Hyperopic RPR in the nasal retina of myopic children is indicative of increased risk for rapid axial elongation and may be a useful metric to support decision-making in myopia management.

Abstract
BACKGROUND We investigated the effect of the number of laser shots applied on the myopic variables to elucidate the mechanism of myopia development in laser-treated retinopathy of prematurity (ROP) eyes. METHODS A total of 33 eyes of 17 infants with ROP who underwent laser treatment were included in the analysis. Cycloplegic retinoscopic refraction testing was carried out and the spherical equivalent (SE) was calculated. Relationships between SE and various variables (including the number of laser shots applied) were examined. In addition, an age-matched control group without ROP was prepared and ocular structural parameters were compared. RESULTS Although there was no statistical difference in axial length (AL) between two groups (p = 0.88), SE was significantly more myopic in the ROP group (p < 0.001). SE was associated with AL, corneal refraction (CR), and crystalline lens power (CLP) in the ROP group. Of these three factors (AL, CR, and CLP), CLP and the number of laser shots applied were significantly correlated (p = 0.003); however, no correlations were observed between the number of laser shots and AL or CR (p = 0.15 and 0.10, respectively). Very similar tendency was observed in the analysis of the difference between right and left eyes in each child. CONCLUSIONS In laser-treated ROP eyes, AL, CR, and CLP were related to the degree of myopia. Moreover, the number of shots applied also affected the myopic status in laser-treated ROP eyes. Among AL, CR, and CLP, only CLP was correlated with the laser shots applied.

Pediatric Health Med Ther 2023; 14:59-69. [PMID: 36814935 PMCID: PMC9939806 DOI: 10.2147/phmt.s391591] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Accepted: 01/31/2023] [Indexed: 02/16/2023] Open
Abstract
The rise in preterm births and higher survival rates of premature infants have led to a global increase in retinopathy of prematurity (ROP), a vasoproliferative retinal disorder common in premature infants. ROP is one of the leading causes of childhood blindness. Clinical manifestation of ROP ranges from mild abnormal retinal neovascularization to bilateral retinal detachment and vision loss. The incidence of ROP is higher in middle income countries, including India, which has the highest number of global preterm births. Low birth weight and low gestational age are the primary risk factors for ROP; however, anemia, cardiac defects, blood transfusion, apnea, sepsis, respiratory distress syndrome, high exposure to oxygen and poor postnatal weight gain may also contribute to its development. India has stringent ROP screening guidelines revised in 2018, and screening of infants with either birth weight <2000 grams or gestational age <34 weeks is mandated. With an improved understanding of the pathogenesis of ROP in the past decades and advances in clinical research, treatment for ROP has evolved from cryotherapy to laser retinal ablation. Most recently, anti-vascular endothelial growth factor (anti-VEGF) drugs have emerged as a favorable treatment option for zone-I and II ROP. This article reviews the current approaches for ROP treatment in India with a particular focus on anti-VEGF drugs. The article also integrates the understanding of safety and risk-benefit evaluation of the current approaches in ROP management. The review concluded that there is a need to increase the ROP screening not only for preterm and low birth weight but also for optimal gestational age infants with healthy birth weight. Anti-VEGF therapies have shown improved efficacy, although studies are required to establish the long-term safety.

Middle East Afr J Ophthalmol 2023; 30:37-43. [PMID: 38435111 PMCID: PMC10903714 DOI: 10.4103/meajo.meajo_117_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2023] [Revised: 11/28/2023] [Accepted: 12/22/2023] [Indexed: 03/05/2024] Open
Abstract
PURPOSE The purpose of this study was to assess the refractive outcomes of patients who underwent indirect laser photocoagulation for prethreshold type 1 retinopathy of prematurity (ROP) and high-risk type 2 prethreshold ROP in comparison to conservatively managed low-risk prethreshold type 2 ROP. METHODS A retrospective analysis was carried out on infants screened for ROP between the years 2015 and 2020. Surviving children who had developed ROP in one or both eyes and received diode laser photocoagulation and those with conservatively managed regressed type 2 ROP who underwent at least one cycloplegic retinoscopy were included in the study. RESULTS A total of 144 patients were screened for ROP between 2015 and 2020 at our institution. One hundred and thirty patients (260 eyes) fulfilled the study criteria and were included in this study. The treated group consisted of 132 eyes of 66 infants, of which 38 (14.6%) eyes had prethreshold type 1 ROP while 94 (36.2%) eyes had high-risk prethreshold type 2. The nontreated control group consisted of 128 (49.2%) eyes of 64 infants with low-risk type 2 prethreshold ROP. Earlier prematurity was found to be a significant determinant of the mean change in spherical equivalent among different gestational age groups (P = 0.035). In our cohort, we found that myopia is significantly related to Zone II ROP in comparison to Zone III ROP in the treated eyes (22% vs. 9%) (P = 0.002). No statistically significant difference was found in the final refraction among the treated eyes in relation to the birth weight or stage of prematurity. CONCLUSION In the present study, the majority of patients who were treated with diode laser for ROP had favorable anatomical and refractive outcomes. In contrast to previous studies that had suggested a trend toward myopia in laser-treated patients, in our study, the majority (71%) were hyperopes. This study suggests that other factors such as the stage and zone of ROP possibly contribute more to the development of myopia than the laser photocoagulation itself.

Abstract
Vision is an important aspect of a child's quality of life and intellectual, social, and emotional development. Disruptions to vision during infancy and early childhood can cause lifelong vision impairment or blindness. However, early identification and treatment of eye disease can prevent loss of sight and its consequent long-term effects. Therefore, screening guidelines exist to guide physicians in detecting the most common threats to sight in the different stages of infancy and childhood. This review describes common causes of pediatric vision impairment, the recommended screening guidelines for diagnosing them, and current treatment modalities.

Abstract
Retinopathy of prematurity (ROP) is a significant cause of potentially preventable blindness in preterm infants worldwide. It is a disease caused by abnormal retinal vascularization that, if not detected and treated in a timely manner, can lead to retinal detachment and severe long term vision impairment. Neonatologists and pediatricians have an important role in the prevention, detection, and management of ROP. Geographic differences in the epidemiology of ROP have been seen globally over the last several decades because of regional differences in neonatal care. Our understanding of the pathophysiology, risk factors, prevention, screening, diagnosis, and treatment of ROP have also evolved over the years. New technological advances are now allowing for the incorporation of telemedicine and artificial intelligence in the management of ROP. In this comprehensive update, we provide a comprehensive review of pathophysiology, classification, diagnosis, global screening, and treatment of ROP. Key historical milestones as well as touching upon the very recent updates to the ROP classification system and technological advances in the field of artificial intelligence and ROP will also be discussed.

Abstract
Blood vessels in the developing retina are formed in concert with neural growth, resulting in functional neurovascular network. Disruption of the neurovascular coordination contributes to the pathogenesis of retinopathy of prematurity (ROP), a potentially blinding retinal neovascular disease in preterm infants that currently lacks an approved drug therapy in the USA. Despite vasculopathy as predominant clinical manifestations, an increasing number of studies revealed complex neurovascular interplays among neurons, glial cells and blood vessels during ROP. Coordinated expression of glia-derived vascular endothelial growth factor (VEGF) in spatio-temporal gradients is pivotal to the formation of well-organized vascular plexuses in the healthy retina, whereas uncoordinated VEGF expression triggers pathological angiogenesis with disorganized vascular tufts in ROP. In contrast with VEGF driving both pathological and physiological angiogenesis, neuron-derived angiogenic factor secretogranin III (Scg3) stringently regulates ROP but not healthy retinal vessels in animal models. Anti-VEGF and anti-Scg3 therapies confer similar high efficacies to alleviate ROP in preclinical studies but are distinct in their disease selectivity and safety. This review discusses neurovascular communication among retinal blood vessels, neurons and glial cells during retinal development and ROP pathogenesis and summarizes the current and emerging therapies to address unmet clinical needs for the disease.

Abstract
PURPOSE To evaluate refraction and its development in young adults born prematurely, screened for retinopathy of prematurity, and to compare with individuals of the same age born at term. MATERIALS AND METHODS The participants were 59 preterms, with a birthweight of ≤ 1500 g, and 43 term-born controls, all born during 1988-1990. The refraction was measured in cycloplegia, and the spherical equivalent (SE) was calculated. The axial length (AL), anterior chamber depth and corneal radius (CR) were measured, and the AL/CR ratio was calculated. RESULTS The mean SE was -0.5 dioptres (D) (SD 2.5) in right eyes (REs) and -0.4 D (SD 2.3) in left eyes (LEs) of preterms, and -0.2 D (SD 1.5) in REs and -0.2 D (SD 1.5) in LEs of controls. The distribution of refraction was wider in the preterm group compared to the control group. In the preterm group, 12% had a SE ≥ 1.5 D, but none of the controls. Ten preterms, but none of the controls, had anisometropia ≥ 1.0 D. The prevalence of astigmatism ≥ 1.0 D was higher in preterms than controls. The SE decreased around 1 D in both preterms and controls from 10 to 25 years of age. The AL and CR were shorter in the preterms; however, the AL/CR ratio was similar in both groups. Within the preterm group, cryotherapy was correlated with astigmatism, but not with SE and anisometropia at this age. CONCLUSION Prematurely born individuals had higher prevalence of refractive errors in young adulthood compared to term-born controls.

Abstract
Retinopathy of prematurity (ROP) is an evolutive and potentially blinding eye disease that affects preterm newborns. Unfortunately, until now no conservative therapy of active ROP with proven efficacy is available. Although ROP is a multifactorial disease, premature exposition to oxygen concentrations higher than those intrauterine, represents the initial pathogenetic trigger. The increase of oxygenation in a retina still incompletely vascularized promotes the downregulation of proangiogenic factors and finally the interruption of vascularization (ischemic phase). However, the increasing metabolic requirement of the ischemic retina induces, over the following weeks, a progressive hypoxia that specularly increases the levels of proangiogenic factors finally leading to proliferative retinopathy (proliferative phase). Considering non-modifiable the coupling between oxygen levels and vascularization, so far, neonatologists and ophthalmologists have "played defense", meticulously searching the minimum necessary concentration of oxygen for individual newborns, refining their diagnostic ability, adopting a careful monitoring policy, ready to decisively intervene only in a very advanced stage of disease progression. However, recent advances have demonstrated the possibility to pharmacologically modulate the relationship between oxygen and vascularization, opening thus the perspective for new therapeutic or preventive opportunities. The perspective of a shift from a defensive towards an attack strategy is now at hand.

Abstract
Retinopathy of prematurity (ROP) is an alteration in the development of the immature retina vascularization that frequently occurs in premature infants and is one of the leading causes of childhood blindness worldwide. In threshold stage retinopathy, laser photocoagulation is the standard treatment, particularly in those located in zone II. However, this therapy destroys parts of the retina and can lead to significant eye complications later in life. For this reason, in the last few years, antivascular endothelial growth factor agents are being used as monotherapy or as coadjuvant with laser, especially in retinopathy located in zone I. More recently, the administration of oral propranolol has been used as prevention and/or treatment of prethreshold retinopathy with encouraging results. This review provides an overview of the current evidence on newer treatment strategies for ROP. KEY POINTS: · Laser is the standard treatment in threshold retinopathy of prematurity (ROP).. · Prethreshold stages of the ROP have no treatment.. · Propranolol may prevent the progression of ROP..

Abstract
BACKGROUND AND OBJECTIVE To determine the effectiveness of aflibercept in retinopathy of prematurity (ROP). PATIENTS AND METHODS We performed a systematic review and meta-analysis of proportions from the literature in PubMed and Cochrane Library using search terms related to the use of aflibercept in ROP. Studies in non-preterm infants or that did not use aflibercept as the initial treatment were excluded. Risk of bias was assessed by the ROBINS-I (Risk Of Bias in Non-randomized Studies of Interventions) tool. RESULTS We identified six case series. Collectively, 218 eyes were treated with aflibercept for ROP. We found an average 97% (95% confidence interval [CI], 93% to 99%) regression rate with aflibercept and an average 16% (95% CI, 5% to 41%) recurrence rate. With the exception of one outlier study, these numbers are similar to previous reports using anti-vascular endothelial growth factor (VEGF) agents in ROP. CONCLUSIONS Aflibercept holds promise for use in ROP and has been demonstrated to be efficacious in six case series. Randomized, controlled clinical trials appear warranted to compare aflibercept with other anti-VEGF agents. [Ophthalmic Surg Lasers Imaging. 2021;52:673-681.].

Abstract
Retinopathy of prematurity (ROP), a vascular proliferative disease affecting preterm infants, is a leading cause of childhood blindness. Various studies have investigated the pathogenesis of ROP. Clinical experience indicates that oxygen levels are strongly correlated with ROP development, which led to the development of oxygen-induced retinopathy (OIR) as an animal model of ROP. OIR has been used extensively to investigate the molecular mechanisms underlying ROP and to evaluate the efficacy of new drug candidates. Large clinical trials have demonstrated the efficacy of anti-vascular endothelial growth factor (VEGF) agents to treat ROP, and anti-VEGF therapy is presently becoming the first-line treatment worldwide. Anti-VEGF therapy has advantages over conventional treatments, including being minimally invasive with a low risk of refractive error. However, long-term safety concerns and the risk of late recurrence limit this treatment. There is an unmet medical need for novel ROP therapies, which need to be addressed by safe and minimally invasive therapies. The recent progress in biotechnology has contributed greatly to translational research. In this review, we outline how basic ROP research has evolved with clinical experience and the subsequent emergence of new drugs. We discuss previous and ongoing trials and present the candidate molecules expected to become novel targets.

The relationship of ocular geometry with refractive error in normal and low birth weight adults. JOURNAL OF OPTOMETRY 2021; 14:50-57. [PMID: 32980297 PMCID: PMC7752971 DOI: 10.1016/j.optom.2020.08.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 07/06/2020] [Accepted: 08/10/2020] [Indexed: 06/11/2023]
Abstract
PURPOSE Low birth weight (BW) individuals have an increased risk for myopic refractive error. However, it is unclear which ocular geometric alterations lead to an increase in myopic refractive error. This study aims to evaluate the impact of ocular biometry in interaction with BW on refractive error. METHODS Participants of the prospective, observational, population-based Gutenberg Health Study (GHS) with self-reported BW aged 40-80 years and objective refraction and optical biometry were included. Linear regression analyses were conducted to evaluate associations between spherical equivalent with corneal power, anterior chamber depth, lens thickness and axial length and its interaction with BW adjusted for age and sex. Low BW was defined as BW<2500 g and normal BW between 2500-4000 g. RESULTS Overall, 5123 participants were included. Linear regression showed an interaction of axial length (B = 0.009/100 g, p = 0.002) with BW on spherical equivalent while corneal power, anterior chamber depth and lens thickness revealed no interaction with BW on refractive error. Furthermore, linear regression analysis revealed, that axial length explains 58% of variance of spherical equivalent in low BW subjects, and 54% in normal BW subjects. In contrast, corneal power explained 1% of variance of spherical equivalent in both groups. CONCLUSIONS Our results indicate that axial length variation explains the majority of variance in refractive error, while steeper corneal shape has no conclusive effects on refractive error. Low BW is not linked to effects of steeper corneal shape on myopic refractive error, while the effect of axial length on myopia is fractionally enlarged in those subjects.

Abstract
PURPOSE To investigate the refractive status and visual acuity of 3-year-old children with extremely low birth weight (ELBW). STUDY DESIGN Retrospective cohort study. METHODS We examined 161 children born between January 2009 and December 2014. The children were divided into five groups for evaluation of visual acuity and refraction: no retinopathy of prematurity (ROP), reverse ROP, photocoagulation (PC) zone II (ZII), PC (ZI), and PC (ZI + lens-sparing vitrectomy [vit]). RESULTS Median (1st quartile, 3rd quartile) gestational age was 25 (24, 26) weeks. Median birth weight was 738 (588, 846) g. Spherical equivalence (SE) was +0.38 (-0.06, +0.75) diopters (D) in no ROP, +0.63 (-0.25, +1.34) D in reverse ROP, +0.38 (-0.75, +1.31) D in PC (ZII), -3.31 (-8.06, +0.16) D in PC (ZI), and -12.00 (-13.50, -4.50) D in PC (ZI+ vit) children. Best corrected visual acuity (BCVA) in log MAR was 0.15 (0.07, 0.26) in no ROP, 0.17 (0.10, 0.30) in reverse ROP, 0.22 (0.10, 0.38) in PC (ZII), 0.45 (0.22, 0.55) in PC (ZI), and 1.10 (0.82, 1.30) in PC (ZI+ vit) children. There was a significant correlation between SE and BCVA (r = -0.43, p < 0.0001). CONCLUSION The no ROP, reverse ROP, and PC (ZII) groups showed no significant differences in SE or BCVA, accounting for 79.5% of ELBW children. SE and BCVA in the PC (ZI) and PC (ZI+ vit) groups were worse than in the other groups. The current results reveal a correlation between SE and BCVA.

Abstract
Objective To investigate refractive error development in preterm children with severe retinopathy of prematurity (ROP) treated with anti-vascular endothelial growth factor (anti-VEGF) agents and laser photocoagulation. Methods Selection criteria were comparative studies that compared the refractive errors in children, birthweights ≤1500 grams and gestational ages ≤30 weeks, and treatments for Type I ROP with intravitreal bevacizumab (IVB) versus laser photocoagulation. Studies were identified using PubMed, Google Scholar, and published reviews. Meta-analyses were performed on the post-treatment outcomes of spherical equivalent (SEQ), cylindrical power, and prevalence of high myopia. Longitudinal development of refractive error in IVB, or in laser-treated children, or in normal full-term children was visually summarized. Results Two randomized controlled trials and 5 non-randomized studies, including a total of 272 eyes treated by IVB and 247 eyes treated by laser, were included in this study. Compared with laser-treated children, IVB-treated children have less myopic refractive error (P<0.001), lower prevalence of high myopia (P<0.05), and less astigmatism (P = 0.02). Conclusions Treatment with IVB is associated with less myopia and astigmatism than laser treatment for infants with severe ROP. Given the complexity of ROP and the variability of dosing, our review supports close monitoring of refractive error outcomes in children treated with IVB.

Abstract
Purpose Ocular morbidities like high refractive error, strabismus, and amblyopia are common among laser-treated retinopathy of prematurity children (ROP). Long-term optical status and refractive outcomes including the sensory outcomes were less investigated in these children from this region. The purpose of our study is to evaluate the long-term outcome (refractive, biometric profile, sensory) of treatment for ROP using laser. Methods This study is a retrospective, cross-sectional, observational, and intervention research among 6-15-year-old children who underwent laser for ROP with a minimum of 6-year follow-up. Results Eighty lasered eyes of 41 children were assessed. Mean age was 9.71 years (±3.39). Seventy-three eyes (91.2%) achieved visual acuity better than 20/40. The mean visual acuity in LogMAR was 0.18 (20/30). The mean spherical equivalence was -5.29 D ± 4.9. Mean astigmatism measured was -1.53 DC (range: +0.50 DC to -4.5DC). Fifty-three eyes (66.25%) had significant astigmatism. The mean axial length was 23.5 ± 1.35 (21-26) mm. Mean lens thickness was 3.76 ± 0.30 (3.03-4.34) mm. Correlation analysis among the low and high spherical equivalent group signified that axial length (P value = 0.001), visual acuity (P value = 0.0002), and myopic shift (P value = 0.0006) were found to be statistically significant. Stereopsis better than 480 s of arc for near was observed in 41% children. Structural posterior pole sequelae developed in 3 eyes (3.75%). Conclusion A significant number of children with high myopia, astigmatism, and strabismus had satisfactory visual outcome observed at long-term follow-up after treatment for ROP using laser. Our study revealed that myopia was influenced by an increase in axial length than the lens thickness.

Abstract
BACKGROUND: With the establishment of laser photocoagulation as a standard treatment modality for prethreshold retinopathy of prematurity (ROP), a dramatic reduction of cases with ROP blindness and severe visual impairment have been reported. In the same time, high refractive errors, a common complication in ROP cases and especially in ROP treated infants, have become the main cause of visual and often severe visual impairment. AIM: The purpose of our study was to analyse the long-term refractive status in children at 3.5 years after laser-treatment for type 1 prethreshold ROP. PATIENTS AND METHODS: A retrospective, one centre study of refractive status of 18 children with laser-treated type 1 prethreshold ROP was conducted. The refraction after cycloplegia with 1% cyclopentolate was measured at a mean age of 3.56 years (SD ± 0.34). Hyperopia was subdivided into two groups – low hyperopia (SE < +5.0 D) and high hyperopia (SE ≥ +5.0 D). Myopia was classified as myopia (SE ≥ –0.25D) and high myopia (SE ≥ -5.0 D). Astigmatism was divided into low astigmatism (plus CD ≥ +1.0 D) and high astigmatism (plus CD ≥ +2.0 D). RESULTS: Thirty-three eyes of 18 children were recruited in the study. Three eyes were excluded because of unfavourable anatomical results. The mean gestational age at birth was 27.3 weeks (24-31 weeks, SD ± 1.78), and the mean birth weight – 928.9 g (550-1500 g, SD ± 252.8). The mean spherical equivalent for the whole group was -1.82 D and ranged from -9.00 D to +4.50 D (SD ± 3.48). Hyperopia was observed in 12 (36.4%) eyes. Myopic refraction had 21 (63.6%) eyes. Astigmatism was detected in 18 (54.5%) eyes. Anisometropia had 3 (16.7%) children. Six children (33.4%) had strabismus (4 esotropia; 2 exotropia). CONCLUSION: High per cent of treated infants for vision-threatening ROP have visual significant refractive errors and strabismus that can cause serious visual impairment if not treated properly and on time.

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
OBJECTIVES To evaluate the success of a sedation protocol of fentanyl and midazolam infusions for infants undergoing laser photocoagulation for retinopathy of prematurity. METHODS This retrospective study included infants receiving a sedation protocol for laser photocoagulation during a 4-year period. The primary objective was protocol success, defined as completion without interruption, absence of protocol dose deviations, and absence of interventions. Secondary objectives compared outcomes between those with and without opioid/benzodiazepine exposure. A logistic regression was used to assess the effect of prior opioid/benzodiazepine exposure on requirement for fentanyl infusion increases. RESULTS Twenty-six infants were included. Seven (26.9%) had protocol success. Sixteen (61.5%) had protocol success, excluding dose deviations. Seventeen (65.4%) experienced ≥1 cardiopulmonary adverse events. Photocoagulation was completed in all cases. CONCLUSIONS Most achieved protocol success, when eliminating dosing deviations. These data indicate that flexibility is needed in fentanyl and midazolam infusion titration, based on clinical response.

Abstract
Diagnosis and management of pediatric retinal conditions such as retinopathy of prematurity (ROP) have been evolving significantly with the availability of new technology and treatments. New imaging systems, telemedicine, tele-education, and anti‒vascular endothelial growth factor (VEGF) intravitreal pharmacotherapy are all changing the way we diagnose and deliver care to children with pediatric retinal disease. Fluorescein angiography and optical coherence tomography have the potential to improve our diagnosis and management of disease, and with improvements in retinal imaging, telemedicine is becoming more feasible. Telemedicine, tele-education, and computer-based image analysis may overcome many of the challenges we face in providing adequate care and access for children with pediatric retinal disease. Treatment options have also expanded with the use of anti-VEGF therapy. Although the use of intravitreal anti-VEGF for ROP has been documented in the literature for more than a decade, many questions still remain about its safety in the pediatric patient population. Several ongoing prospective studies are exploring the utility of anti-VEGF agents for ROP, with attention to the optimal dose of drug, systemic safety, and our understanding of recurrence of disease. This review aims to provide an update on current diagnostic and therapeutic modalities, focusing predominantly on the role of anti-VEGF therapy, for the management of ROP and other pediatric retinal vascular diseases.

Abstract
Purpose To compare refractive and biometric outcomes in patients with type 1 retinopathy of prematurity (ROP) treated with intravitreal injection of ranibizumab (IVR) versus bevacizumab (IVB), at a corrected age of 3 years. Methods A retrospective case series compared cycloplegic refractive statuses and biometric statuses in patients who received either IVR or IVB for type 1 ROP, from April 2011 to April 2014. Results A total of 62 eyes (33 patients) with type 1 ROP were evaluated (26 eyes in 13 IVR patients and 36 eyes in 20 IVB patients). There were no differences in birth statuses including gestational age and birth body weight between the two groups. The prevalence of refractive error greater than 1 D was higher in the IVB group (p = 0.03), and there was a higher prevalence of high myopia (<-5.0 D, p = 0.03) in the IVB group. Comparisons in biometric finding showed that IVB patients had shallower anterior chamber depth (p = 0.01). Conclusion Both IVR and IVB showed low refractive errors, even followed at the corrected age of 3 years. No difference was noted between the two groups in refractive statuses. However, IVB was associated with shallower anterior chamber and higher prevalence of refractive error at the corrected age of 3 years. This trial is registered with NCT03334513.

Abstract
Background Retinopathy of Prematurity (ROP) is one of the most common causes of childhood blindness worldwide. Comparisons of anti-VEGF and laser treatments in ROP are relatively lacking, and the data are scattered and limited. The objective of this meta-analysis is to compare the efficacy of both treatments in type-1 and threshold ROP. Methods A comprehensive literature search on ROP treatment was conducted using PubMed and Embase up to March 2017 in all languages. Major evaluation indexes were extracted from the included studies by two authors. The fixed-effects and random-effects models were used to measure the pooled estimates. The test of heterogeneity was performed using the Q statistic. Results Ten studies were included in this meta-analysis. Retreatment incidence was significantly increased for anti-VEGF (OR 2.52; 95% CI 1.37 to 4.66; P = 0.003) compared to the laser treatment, while the incidences of eye complications (OR 0.29; 95% CI 0.10 to 0.82; P = 0.02) and myopia were significantly decreased with anti-VEGF compared to the laser treatment. However, there was no difference in the recurrence incidence (OR 1.86; 95% CI 0.37 to 9.40; P = 0.45) and time between treatment and retreatment (WMD 7.54 weeks; 95% CI 2.00 to 17.08; P = 0.12). Conclusion This meta-analysis indicates that laser treatment may be more efficacious than anti-VEGF treatment. However, the results of this meta-analysis also suggest that laser treatment may cause more eye complications and increase myopia. Large-scale prospective RCTs should be performed to assess the efficacy and safety of anti-VEGF versus laser treatment in the future.

Abstract
PURPOSE Indian children belong to a diverse socioeconomic strata with retinopathy of prematurity (ROP) developing in mature, higher birth weight babies as well. The purpose of our study is to analyze the long-term status of refractive errors and its relationship with ocular biometry in children with ROP who were laser treated at a tertiary center in North India. METHODS Cross sectional study. Children (<16 years) enrolled from January 2014 to December 2014 with a history of laser treatment for ROP and examined for refractive and biometric status. RESULTS Thirty-six children presenting to us at the mean age of 7.37 ± 3.07 years (6-15 years) were included. Mean spherical equivalent (SE) was -4.05 D ± 5.10. 75% were myopic, with high astigmatism in 31%. Higher lens thickness (P = 0.03) and higher SE (P = 0.002) at 1 year postnatal age were predictors of larger SE. 79.4% achieved a favorable functional outcome (visual acuity ≥20/40). 5.88% achieved unsatisfactory outcome (<20/200) despite having a favorable structural outcome. CONCLUSION There are a substantial number of children who develop myopia and high astigmatism while undergoing laser treatment for ROP. We found myopia in our cohort to be lenticular and greater axial length contributing to the development of high myopia. An initial large refractive error predicts the future development of myopia in these children. Nearly 6% of patients with good structural outcome have unexplained subnormal vision. Our threshold for prescribing glasses in these children should be low.

Abstract
OBJECTIVE The aim of this study was to evaluate the visual and structural outcomes of eyes that received ranibizumab as treatment for retinopathy of prematurity (ROP). METHODS This was a retrospective case series of infants who received a 0.2 mg (0.02 mL) intravitreal injection of ranibizumab as the primary treatment for type 1 ROP. Outcome measures included regression or recurrence of ROP, complications of treatment, and assessment of visual acuity and refractive error. RESULTS Forty-two eyes of 21 infants (13 male) were included. Mean gestational age and birth weight were 24.6 ± 1.3 weeks and 613 ± 91 g, respectively. Mean age at injection was 37.4 ± 2.2 weeks postmenstrual age, and mean follow-up period was 10.1 ± 7 months. Active neovascularization regressed rapidly, and anatomical outcomes were favourable in all eyes. Twelve eyes of 6 infants received supplemental laser photocoagulation at a mean post-menstrual age (PMA) of 72.0 ± 27.3 weeks when vascularization had not advanced beyond zone II. Visual acuity was measurable in 28 of 42 eyes. Mean visual acuity was 0.94 ± 0.36 logMAR. Mean spherical equivalent was +1.00. There were no ocular or systemic complications in these patients and no cicatricial complications were observed with no progression to stage 4 or 5 disease. CONCLUSIONS A single intravitreal dose of 0.2 mg (0.02 mL) ranibizumab showed favourable anatomical and functional outcomes in eyes with type 1 ROP.

Abstract
The understanding, diagnosis, and treatment of retinopathy of prematurity have changed in the 70 years since the original description of retrolental fibroplasia associated with high oxygenation. It is now recognized that retinopathy of prematurity differs in appearance worldwide and as ever smaller and younger premature infants survive. New methods are being evaluated to image the retina, diagnose severe retinopathy of prematurity, and determine windows of time for treatment to save eyes and improve visual and neural outcomes. New treatments to promote physiologic retinal vascular development, vascular repair, and inhibit vasoproliferation by regulating proteins involved in vascular endothelial growth factor, insulin-like growth factor, or erythropoietin signaling. Reducing excessive oxidative/nitrosative stress and understanding progenitor cells and neurovascular and glial vascular interactions are being studied.

Abstract
PURPOSE To report the visual outcome and refractive status in first 3 years of age in preterm infants suffered from laser-treated Type 1 retinopathy of prematurity (ROP): a 6-year review in Hong Kong DESIGN: Retrospective case series METHODOLOGY: Clinical records of all infants suffered from Type 1 ROP who had undergone laser therapy between 2007 and 2012 were retrospectively reviewed. Basic demographic data, serial changes of refractive error, visual acuity, severity of ROP and laser were analyzed. Correlation with myopia and astigmatism progression, body weight, height, growth and gestational age were also analyzed. RESULT Among 494 babies screened, 14 Chinese babies (26 eyes) recruited with 1:1 male-to-female ratio in this study. All eyes showed gradual progression of myopia in first 3 years of age but no significant change of astigmatism. Further correlation analysis showed no correlation with laser energy consumed, birth weight (p = 0.14), head circumference growth (p = 0.57) and body weight growth (p = 0.71). However, severity of myopia was related to the post-conceptual age when receiving laser therapy (p < 0.005), gestation age (p = 0.02) and possibly body height growth with age (p = 0.05). CONCLUSION Myopia in early life is one of the most common ocular sequelae in Type 1 ROP survivors. Early detection of refractive error is important for prompt correction and visual rehabilitation to prevent amblyopia.

Abstract
PURPOSE OF REVIEW To review the most recent literature regarding the clinical experience of antivascular endothelial growth factor (anti-VEGF) therapies in the treatment of retinopathy of prematurity (ROP). RECENT FINDINGS Anti-VEGF agents in stage 3+ and aggressive posterior ROP have been shown to induce rapid ROP regression. However, significant reoccurrence rates can require repeat injections and thus longer term and more frequent follow-up. Initial studies reflect conflicting evidence regarding significant systemic side effects of these treatments, and outcomes in these patients past the first few years of life are yet to be definitively determined. SUMMARY Although anti-VEGF therapies show promise in the treatment of ROP, frequent reoccurrences and lack of thorough data about long-term side effects of pharmacologic intervention necessitate further research before anti-VEGF agents become the mainstay of ROP management.

Abstract
Purpose The purpose of this study was to report on the axial length, refraction, and retinal vascularization 1 year after ranibizumab or bevacizumab treatment for threshold retinopathy of prematurity. Methods The authors conducted a comparative, consecutive, original study. Results Twenty-five eyes of 13 patients with threshold retinopathy of prematurity received one intravitreal ranibizumab treatment, and 15 eyes of eight patients received one intravitreal bevacizumab treatment. In the ranibizumab group, the mean gestational age was 26.15±2.08 weeks, with a mean birth weight of 811.15±287.3 g. In the bevacizumab group, the mean gestational age was 26.50±2.14 weeks, with a mean birth weight of 938.38±200.4 g. The mean axial length was 20.34±0.97 mm and the mean spherical equivalent was 0.46±1.36 D in the ranibizumab group, with complete vascularization in 15 of 25 (60%) eyes. The mean axial length was 20.91±1.54 mm and the mean spherical equivalent was −0.60±3.86 D in the bevacizumab group, with complete vascularization in seven of 15 (46.7%) eyes. Conclusion There were no significant differences in the axial length and refraction between children with threshold retinopathy of prematurity who received intravitreal bevacizumab compared to those who received ranibizumab after 1 year of follow-up. It appeared that the ranibizumab treatment could achieve more complete retinal vascularization than the bevacizumab treatment; however, there was no statistical significance and long-term follow-up is needed.

Abstract
Retinopathy of prematurity (ROP) is a complex disease characterized by an aberrant developmental retinal angiogenesis in preterm infants and can carry significant visual morbidity, including retinal detachment and blindness. Though large scale, randomized clinical trials have improved our understanding of the pathophysiology and progression of the disease, the management of ROP remains a challenge for ophthalmologists. This review addresses the up-to-date screening approach, diagnosis, and treatment guidelines for ROP in the US.

Abstract
PURPOSE To assess time to stabilization and factors associated with changes in biometric parameters after scleral buckling (SB). DESIGN Prospective case series. METHODS Seventeen eyes with primary rhegmatogenous retinal detachment (RRD) that underwent SB at the Singapore National Eye Centre were enrolled. SB surgery was performed using an encircling element and segmental buckle. Axial length (AL); anterior chamber depth (ACD), defined as the distance from the corneal epithelium to the anterior lens surface; anterior/posterior corneal curvature (K); and refraction were measured preoperatively and at week 1 and months 1, 3, 6, 9, and 12 postoperatively. Stability of each parameter was defined as the earliest time point at which there is no significant difference compared to its value at month 12. RESULTS AL increased (26.09 ± 1.46 to 26.51 ± 1.96, P = .01), ACD decreased (3.84 ± 0.47 to 3.32 ± 0.57, P < .001), and a myopic shift of 1.04 diopters (95% CI 0.03-2.05, P = .04) occurred at month 12. Anterior/posterior K were not significantly changed from baseline. AL stabilized at month 3 while ACD and spherical equivalent (SE) stabilized at week 1. Cryotherapy was associated with greater increase in AL (P = .001) and myopic shift (P = .02). More extensive segmental buckling was associated with greater increase in AL (P = .009) and myopic shift (P = .03). CONCLUSIONS Our study suggests that patients requiring cataract surgery after SB should have biometry performed no earlier than 3 months post SB surgery, and intraocular lens power calculation with a fourth-generation formula. A greater increase in AL and myopic shift was associated with cryotherapy and more extensive segmental buckling.

Abstract
PURPOSE To assess ocular biometric outcomes following intravitreal bevacizumab (IVB) monotherapy for retinopathy of prematurity (ROP) and compare these results with those of laser photocoagulated infants and with the ones with spontaneously regressed ROP. MATERIALS AND METHODS Premature infants including those who underwent IVB monotherapy (Group 1) or laser photocoagulation (Group 2) for ROP and infants with spontaneously regressed ROP (Group 3) were recruited for the study. Refractive errors and ocular biometric parameters (Axial length [AL], anterior chamber depth [ACD], and lens thickness [LT]) were measured at adjusted 1 year of age in all subjects. RESULTS There was no significant difference of spherical equivalent (SE) value between the groups (P = 0.781). The incidence of high myopia was 7.4% in Group 1 and 12.7% in Group 2 (P = 0.081). No infants exhibited high myopia in Group 3. LT was greater in Group 2 when compared to Group 1 and Group 3 (P = 0.011). Lower SE was significantly correlated to longer AL in Group 1 (r = -0.656, P = 0.015). There was a significant positive correlation between SE and ACD values in Group 2 (r = 0.391, P = 0.005). CONCLUSION The study showed no significant difference of SE between the groups. High myopia was only present among the treated infants either with IVB or laser. Infants who received laser treatment significantly had thicker lenses.

Abstract
BACKGROUND/AIM To evaluate refractive and strabismic results and the efficacy of intravitreal bevacizumab in retinopathy of prematurity (ROP) ineligible for laser therapy. MATERIALS AND METHODS Thirty-nine eyes of 20 consecutive infants with high-risk prethreshold ROP (11 infants with Zone I and 9 infants with Zone II disease) who were ineligible for laser therapy due to systemic and/or ocular conditions were treated with intravitreal bevacizumab. Recurrent retinopathy was treated with laser ablation. The final follow-up examination was performed at 29.8 ± 6.0 months of corrected age. RESULTS All eyes responded to the initial treatment with intravitreal bevacizumab. ROP recurred in 8 eyes (36%) with initial Zone I disease and in only 2 eyes (11%) with initial Zone II disease, which were successfully treated with laser ablation. No eye developed myopia higher than 5.0 diopters. At 2.5 years, the Zone I eyes that had received laser treatment appeared to be more myopic than the Zone I eyes treated only with intravitreal bevacizumab (P = 0.038). A tendency for a higher incidence of strabismus after additional laser therapy was also noted, but was not significant (P = 0.22). CONCLUSION Avoidance or even deferral of laser ablation with intravitreal bevacizumab may lead to less myopization in ROP compared with conventional laser treatment.

Abstract
PURPOSE To compare the effect and the treatment outcomes of bevacizumab and ranibizumab in the treatment of Type 1 retinopathy of prematurity (ROP). METHODS This was a bicentered retrospective case series performed at institutional referral centers. Seventy-two eyes of 37 patients who had intravitreal injections of either bevacizumab or ranibizumab as the primary treatment for Type 1 ROP were included. Outcomes' measures included regression and recurrence of ROP, the surgical complications, and refractive errors at a corrected age of 1 year. RESULTS All but one eye in the bevacizumab group had retinal neovascularization and plus disease regression after anti-vascular endothelium growth factor treatment. Neither recurrence of ROP nor major ocular complications, including cataract, retinal detachment, and endophthalmitis occurred in any of the treated eyes. There were no significant differences in mean refractive errors between the patients treated with intravitreal injections of bevacizumab or ranibizumab at the corrected age of 1 year. A significantly higher chance of high myopia was noted in the bevacizumab group (P = 0.03). CONCLUSION Both bevacizumab and ranibizumab showed similar efficacy in the regression of ROP with minor mean refractive errors at 1 year of corrected age. However, high myopia was more prevalent in the bevacizumab-treated eyes.

Abstract
PURPOSE To evaluate the refractive development of premature infants with retinopathy of prematurity (ROP) after treatment with laser photocoagulation or intravitreal injection of bevacizumab (IVB). METHODS The medical records of patients with ROP treated between 2003 and 2012 who underwent yearly follow-ups were retrospectively reviewed. Patients with residual ROP abnormalities were excluded. The cycloplegic refraction at 3 years of age, assessed using an autorefractometer, was recorded. RESULTS In total, 54 eyes from 54 patients were enrolled. Patients were divided into 4 groups: group 1, including 14 eyes of 14 patients treated with laser therapy; group 2, 15 eyes of 15 patients treated with IVB; group 3, 13 eyes of 13 patients with non-type 1 ROP under conservative follow-up, and group 4, 12 eyes of 12 premature patients without ROP. The mean spherical equivalent at 3 years of age was -1.71 ± 1.27 dpt in group 1, -1.53 ± 2.20 dpt in group 2, 0.63 ± 1.37 dpt in group 3, and 0.41 ± 1.95 dpt in group 4. The mean refractive error differed significantly among the 4 groups (p < 0.001). Patients in groups 1 and 2 were more prone to myopia compared with those in groups 3 and 4. Furthermore, patients with type 1 ROP treated by laser photocoagulation (group 1) and those treated by IVB (group 2) had similar refraction (p = 1). CONCLUSIONS The results of this study suggest that treatment-demanding ROP eyes are susceptible to more severe myopia with age compared with eyes without ROP or those with spontaneously regressed ROP. In addition, the myopic status between laser and IVB treatment did not differ statistically.

Abstract
PURPOSE To report the complication of infectious ulcerative keratitis after laser photocoagulation and pars plana vitrectomy (PPV) for retinopathy of prematurity (ROP). METHODS A retrospective chart review of infants treated for ROP with plus disease between 2004 and 2013 at University Hospital, Newark, New Jersey. RESULTS Of the 110 eyes (55 patients) that underwent treatment for ROP, 8 (7.27%) eyes were noted to develop infectious ulcerative keratitis in 4 neonates (4 eyes after laser photocoagulation and 4 eyes after PPV). All 8 eyes that developed ulcerative keratitis had a preceding corneal epithelial defect followed by corneal stromal haze. Seven of 8 eyes developed epithelial defect within 8 days of the procedure. All epithelial defects progressed to ulcerative keratitis within 7 days. A total of 10 (9.1%) eyes developed postoperative epithelial defects, and 8 (80%) of these eyes were ultimately diagnosed as having ulcerative keratitis. Four (4.08%) of 98 eyes treated with laser photocoagulation alone developed infective ulcerative keratitis, compared to 4 (33.33%) of 12 eyes treated with PPV. Because keratitis healed, corneal opacification ensued and covered 10% to 90% of the corneal surface area. Five of the 8 eyes had positive culture of corneal scrapings: 2 grew coagulase-negative Staphylococcus and Stenotrophamonas; 1 grew coagulase-negative Staphylococcus; 1 grew Streptococcus viridans, and 1 grew Staphylococcus hominis, Streptococcus mitis, and Streptococcus viridans. All 8 eyes were treated with antibiotic eye drops. CONCLUSIONS Infectious ulcerative keratitis developed in a small, but significant, percentage of patients undergoing treatment for ROP. Postoperative corneal epithelial defects with subsequent corneal haze appear to be involved in the progression to ulcerative keratitis.

Abstract
PURPOSE A recent threefold increase in laser treatment for advanced retinopathy of prematurity (ROP) triggered a nationwide preschool ophthalmic and developmental status among extremely preterm survivors. Here, we discuss refraction and visual acuity. METHODS Survivors (n = 178) from a national birth cohort (February 2004 to March 2006) of gestational age <28 weeks (PT) and 56 full-term (FT) controls attended for evaluation at age 4 years. Cycloplegic refraction and keratometry were achieved by Retinomax autokeratorefractor and visual acuities by symbol recognition (HOTV, logMAR). RESULTS The refractive distribution presented a myopic tail (4.5%) and a hyperopic tail (11.9% ≥+2.5 D) as special preterm features, and corneas were more curved. Astigmatism and anisometropia were only marginally increased, and visual acuities were generally good. Best-corrected binocular median logMAR visual acuity was 0.1 in FT and 0.2 in PT, in Snellen equivalents 0.8 and 0.63. Snellen acuity ≤0.5 occurred across the ROP subgroups, but mainly in those with at least ROP stage 3. Two children had low vision. CONCLUSIONS The overall fair outcome for refraction and function is in accordance with other recent northern Europe experience. The results differ in particular from the poorer ophthalmic outcomes reported in the pioneer US treatment studies (cryotherapy for ROP and ETROP). The diode laser ablations (n = 32) appeared effective in our series; except one child, all treated subjects had good or fair social vision at the age of 4 years.

Abstract
PURPOSE To investigate the clinical and macular spectral-domain optical coherence tomography (SD-OCT) findings after intravitreal ranibizumab treatment for type 1 retinopathy of prematurity (ROP). METHODS Eighteen eyes of 10 premature infants with type 1 ROP were retrospectively studied. All eyes were treated with intravitreal ranibizumab as monotherapy. Macular SD-OCT was performed before and after intravitreal ranibizumab therapy using a portable SD-OCT machine; the follow-up images were taken 1 day, 1 week, 1 month, and 2 months after therapy. RESULTS Among the 10 infants, there were six males and four females. Mean central foveal thickness before and 2 months after intravitreal ranibizumab was 292.5 ± 61.4 and 171.6 ± 21.7 µm, respectively. Differences were statistically significant (P = .01). Sixteen eyes of eight patients had macular edema before treatment. Two eyes of two patients developed a crack in the outer hyperreflective line on SD-OCT corresponding with retinal pigment epithelium with serous retinal detachment 1 day after treatment. Macular edema regressed in all patients 2 months after intravitreal ranibizumab therapy. Mean follow-up time was 11.4 ± 1.5 months. No recurrence was seen except in both eyes of one patient treated with intravitreal ranibizumab monotherapy. CONCLUSIONS Intravitreal ranibizumab injection is effective for the treatment of type 1 ROP as a monotherapy agent; however, macular changes not seen with indirect ophthalmoscope may develop.

Abstract
BACKGROUND To describe outcomes in a cohort of extremely premature infants treated for aggressive posterior retinopathy of prematurity by diode laser panretinal photocoagulation. DESIGN Retrospective study. PARTICIPANTS Fifteen eyes in eight infants. METHODS A review was carried out on infants between 23 and 25.6 weeks gestational age admitted to The Royal Brisbane and Women's Hospital neonatal intensive care unit between 1992 and 2009. MAIN OUTCOME MEASURES Success of treatment, visual and refractive outcomes. RESULTS Five hundred fifty-four infants were admitted to neonatal intensive care unit, 373 survived till screening, and 304 had retinopathy of prematurity. Sixty-six infants required treatment, and eight of these had aggressive posterior retinopathy of prematurity (2.5% of all infants with retinopathy of prematurity). Mean gestational age was 24.2 weeks, mean birthweight was 634 g, and treatment occurred at mean 34.1 weeks post-menstrual age. The mean total number of burns per eye was 2967. Five of 15 treated eyes required retreatment. Two patients subsequently died of unrelated causes. Regression occurred in 9 of 11 remaining eyes; one eye progressed to stage 4b and another to stage 5 retinopathy of prematurity. Vitrectomy was performed in two eyes. Five eyes had 6/12 vision, one had 3/60, and three had no perception of light. Of the remaining two eyes, one had good fixation and the other had poor fixation. CONCLUSIONS Despite good structural outcomes, visual outcomes for conventional laser treatment of aggressive posterior retinopathy of prematurity are poor.

Abstract
BACKGROUND To report the efficacy of laser diode therapy in the treatment of retinopathy of prematurity (ROP) in extremely premature (EP) infants over an 18-year period. DESIGN Retrospective study. PARTICIPANTS One hundred twenty-eight eyes in 66 infants treated between 23 and 25.6 weeks. METHODS Five hundred fifty-four infants between 23 and 25.6 weeks gestational age (GA) were admitted to The Royal Brisbane and Women's Hospital Neonatal Intensive Care Unit (NICU) between 1992 and 2009. Three hundred seventy-three patients survived to undergo screening, 304 were diagnosed with ROP, and 66 infants required diode laser therapy. MAIN OUTCOME MEASURES Success of treatment, visual and refractive outcomes. RESULTS One hundred twenty-eight eyes from 66 infants (18.8% of those screened) underwent laser treatment with a mean GA of 24.3 weeks and mean birth weight of 711.4g. Fifty-six eyes were treated at pre-threshold disease, and 72 eyes at threshold disease. Over the study period, the number of laser spots and regression rate of ROP increased, while the frequency of re-treatment decreased. At 40 weeks, 119 eyes had regressed ROP (93%), two advanced to stage 4a, three to stage 4b and four to stage 5. Aggressive posterior ROP (AP-ROP) occurred in 15 eyes (11.7% of those treated). Forty-three patients (65%) were followed up for a mean of 56.5 months. The number of laser spots correlated well with subsequent refractive error but poorly with corrected visual acuity. CONCLUSIONS In EP infants, laser diode therapy is an effective technique to halt the progression of ROP in most cases. AP-ROP is uncommon, even in this subgroup of extremely premature infants.

Abstract
PURPOSE We investigated longitudinally the refraction development in children with regressed retinopathy of prematurity (ROP), including those with and those without a history of peripheral retinal laser photocoagulation. METHODS Longitudinal (0-7 years) cycloplegic refraction data were collected prospectively for two groups of preterm children: severe ROP group included those with regressed ROP following bilateral panretinal laser photocoagulation (n = 37; median gestational age [GA] = 25.2; range, 22.7-27.9 weeks) and mild/no ROP group included those with spontaneously regressed ROP or no ROP (n = 27; median GA = 27.1; range, 23.1-32.0 weeks). Analyses were based on spherical equivalent (SEQ), anisometropia, astigmatism, and age (corrected for gestation). RESULTS The prevalence, magnitude, and rate of myopic progression all were significantly higher in the severe ROP group than in the mild/no ROP group. Longitudinal SEQ in the severe ROP group were best fit with a bilinear model. Before 1.3 years old, the rate of myopic shift was -4.7 diopters (D)/y; after 1.3 years, the rate slowed to -0.15 D/y. Longitudinal SEQ in the mild/no ROP group was best fit with a linear model, with a rate of -0.004 D/y. Anisometropia in the severe ROP group increased approximately three times faster than in the mild/no ROP group. In the severe ROP group, with-the-rule astigmatism increased significantly with age. CONCLUSIONS The severe ROP group progressed rapidly toward myopia, particularly during the first 1.3 years; anisometropia and astigmatism also increased with age. The mild/no ROP group showed little change in refraction. Infants treated with laser photocoagulation for severe ROP should be monitored with periodic cycloplegic refractions and provided with early optical correction.

Abstract
PURPOSE We tested the hypothesis that recombinant human VEGF-A165b and the serine arginine protein kinase (SRPK) inhibitor, SRPIN340, which controls splicing of the VEGF-A pre-mRNA, prevent neovascularization in a rodent model of retinopathy of prematurity (ROP). METHODS In the 50/10 oxygen-induced retinopathy (50/10 OIR) model that exposes newborn rats to repeated cycles of 24 hours of 50% oxygen alternating with 24 hours of 10% oxygen, pups received intraocular injections of SRPIN340, vehicle, VEGF165b, anti-VEGF antibody, or saline. Whole mounts of retinas were prepared for isolectin immunohistochemistry, and preretinal or intravitreal neovascularization (PRNV) determined by clock hour analysis. RESULTS The anti-VEGF antibody (P < 0.04), rhVEGF165b (P < 0.001), and SRPIN340 (P < 0.05) significantly reduced PRNV compared with control eyes. SRPIN340 reduced the expression of proangiogenic VEGF165 without affecting VEGF165b expression. CONCLUSIONS These results suggest that splicing regulation through selective downregulation of proangiogenic VEGF isoforms (via SRPK1 inhibition) or competitive inhibition of VEGF signaling by rhVEGF165b has the potential to be an effective alternative to potential cyto- and neurotoxic anti-VEGF agents in the treatment of pathological neovascularization in the eye.

Abstract
PURPOSE To evaluate refractive error in infants who underwent intravitreal bevacizumab injection for treatment of threshold retinopathy of prematurity (ROP). DESIGN Retrospective nonrandomized interventional comparative study. METHODS The study group included all infants who consecutively received a single intravitreal bevacizumab (0.375 mg or 0.625 mg) injection for therapy of threshold ROP in fundus zone I or zone II. The control group included infants who had previously undergone retinal argon laser therapy of ROP. The follow-up examination included refractometry under cycloplegic conditions. RESULTS The study group included 12 children (23 eyes; mean birth weight: 622 ± 153 g; gestational age: 25.2 ± 1.6 weeks) and the control group included 13 children (26 eyes; birth weight: 717 ± 197 g; gestational age: 25.3 ± 1.8 weeks). Both groups did not differ significantly in birth age and weight and follow-up. At the end of follow-up at 11.4 ± 2.3 months after birth, refractive error was less myopic in the study group than in the control group (-1.04 ± 4.24 diopters [median: 0 diopters] vs -4.41 ± 5.50 diopters [median: -5.50 diopters]; P = .02). Prevalence of moderate myopia (17% ± 8% vs 54% ± 10%; P = .02; OR: 0.18 [95% CI: 0.05, 0.68]) and high myopia (9% ± 6% vs 42% ± 10%; P = .01; OR: 0.13 [95% CI: 0.03, 0.67]) was significantly lower in the bevacizumab group. Refractive astigmatism was significantly lower in the study group (-1.0 ± 1.04 diopters vs 1.82 ± 1.41 diopters; P = .03). In multivariate analysis, myopic refractive error and astigmatism were significantly associated with laser therapy vs bevacizumab therapy (P = .04 and P = .02, respectively). CONCLUSIONS In a 1-year follow-up, a single intravitreal bevacizumab injection as compared to conventional retinal laser coagulation was helpful for therapy of ROP and led to less myopization and less astigmatism.
