Sen P, Bhende P, Maitra P. Surgical outcomes in aggressive retinopathy of prematurity (AROP)-related retinal detachments. Indian J Ophthalmol 2023; 71:3454-3459. [PMID: 37870006 PMCID: PMC10752330 DOI: 10.4103/ijo.ijo_2999_22] [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: 11/13/2022] [Revised: 12/30/2022] [Accepted: 06/07/2023] [Indexed: 10/24/2023] Open
Abstract
Introduction Aggressive retinopathy of prematurity (AROP) is a severe and progressive variant of retinopathy of prematurity (ROP) rapidly forming fibrous tissue extending from the disc toward the posterior lens surface progressing to Stage 5 disease without traversing the classical course that includes Stages 1 to 3. Since AROP behaves differently from type 1 ROP, this study was undertaken to evaluate the surgical outcome of AROP-related detachments. Methods Retrospective analysis of data from electronic medical records of babies diagnosed with AROP-related detachments who underwent micro-incision vitrectomy surgery (MIVS) was included. The demographic data, details of primary intervention (laser and/or intravitreal bevacizumab), and surgery were noted. In a subset of patients, surgical intervention was planned early at the onset of fibrovascular tissue. Results 43 eyes of 26 babies with median birth weight 1175 g and median gestational age of 29 weeks were analyzed. 42/43 eyes underwent primary intervention in form of laser and/or anti-VEGF injection before surgery. 41.8%, 25.5%, and 32.5% eyes progressed to stages 4A, 4B, and 5, respectively, requiring surgical intervention. 66% eyes underwent lensectomy and vitrectomy (LV), and 44% eyes underwent lens sparring vitrectomy (LSV). 58% eyes had attached macula. 44% eyes that had a relatively less vascular diseases had better anatomical outcome (P = 0.019). At final follow-up, 53.4% eyes followed or at least had light fixation, and 77.7% eyes undergoing LSV fixated and/or followed light compared to 33% for LV (P = 0.04). Conclusion Challenges in AROP include rapid progression to advanced stages of ROP requiring close monitoring and multiple interventions. Surgeries for AROP have a favorable anatomical and functional outcome in 58% and 53%, respectively. Eyes undergoing lens sparing vitrectomy had better visual outcomes.

Safety and efficacy of intravitreal anti vascular endothelial growth factor for severe posterior retinopathy of prematurity with flat fibrovascular proliferation. World J Clin Pediatr 2023; 12:220-229. [PMID: 37753496 PMCID: PMC10518743 DOI: 10.5409/wjcp.v12.i4.220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 06/26/2023] [Accepted: 07/07/2023] [Indexed: 09/06/2023] Open
Abstract
BACKGROUND Intravitreal anti-vascular endothelial growth factor (IVA) injection is known to cause contraction of fibrovascular proliferation (FVP), when present in severe retinopathy of prematurity (ROP). AIM To assess the structural outcomes of IVA injection in the treatment of severe posterior ROP with significant FVP. METHODS It was a retrospective study in which 36 eyes of 18 preterm babies who developed > 4 clock hours of FVP in zone I or posterior zone II, were treated with either intravitreal 0.625 mg bevacizumab or intravitreal 0.2 mg of ranibizumab. Favorable structural outcome included resolution of plus disease and FVP without the development of tractional retinal detachment. Secondary outcome measure included either full retinal maturation at follow-up or development of recurrent disease requiring additional treatment. Adverse outcomes included progression to retinal detachment. RESULTS The mean gestational age of the 18 preterm babies was 30 wk (range 27-36), and mean birth weight was 1319 g (range 650-1980 g). Mean post-menstrual age (PMA) at the time of primary treatment was 35.5 wk (range 31-41 wk). All eyes showed regression of plus disease and FVP. 5 eyes of 3 babies showed reactivation of disease and were treated with repeat IVA (n = 2 eyes) or peripheral laser photocoagulation (n = 3 eyes) respectively. 16 out of 36 (44%) reached retinal vascular maturation at final follow up at 5 years. CONCLUSION There was good resolution of severe posterior ROP with FVP with IVA, with retinal maturity of 44% at 5 year follow-up and a reactivation rate of 13.8%. When the IVA injection is given prior to 37 wk PMA, while disease is in phase 2, it is less likely to cause contracture of pre-existing FVP.

Abstract
PURPOSE To study treatment outcomes of combination treatment of intravitreal anti-vascular endothelial growth factor (VEGF) injection and laser photocoagulation in Type 1 Retinopathy of Prematurity (ROP) and Aggressive Posterior ROP (APROP). METHODS This is a retrospective observational study of 87 eyes of 48 premature babies who presented with Type I ROP or APROP and were treated with combination of laser and anti-VEGF therapy. Retrospective evaluation of case records was done to collect data on gestational age, birth weight, age at intervention, anterior segment and fundus findings, intervention with laser and anti-VEGF and response to treatment. Outcome measure was defined as attached retina at posterior pole at last follow-up. RESULTS Mean gestational age was 29.1 weeks, and mean birth weight was 1226.9 gms. Sixty-six (75.8%) eyes had Type I ROP and 21 (24.1%) eyes had APROP at presentation. Five eyes (3 patients) were lost to follow-up after treatment. Of 82 eyes, 80.5% (66 eyes) showed regression of ROP following combination treatment and 19.5% (16 eyes) needed surgery. Of these, 15 underwent surgery and 12 had successful outcome. Mean follow-up duration of patients was 52 weeks. Finally, 95.1% (78 eyes) had attached retina at posterior pole and 4.9% (4 eyes) had detached retina. CONCLUSION We conclude that combination therapy is an effective and safe treatment strategy for Type I ROP and APROP.

[PMID: 33514899 PMCID: PMC8115681 DOI: 10.1038/s41433-021-01392-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 11/13/2020] [Accepted: 01/05/2021] [Indexed: 01/30/2023] Open
Abstract
A review of literature was performed, focused on the etiopathogenesis of aggressive posterior retinopathy of prematurity (APROP), the characteristic and atypical clinical features, management strategies, anatomical and visual outcomes. Characteristically APROP has zone I/posterior zone II involvement with prominent plus disease, featureless junction, large vascular loops, flat extra-retinal fibrovascular proliferation, and a rapidly progressive course. The risk factors for APROP are extreme prematurity (birth weight ≤1000 gram and/or gestational age ≤28 weeks), dysregulated oxygen supplementation, intrauterine growth retardation, sepsis, and thrombocytopenia. The uncommon presentations include small zone I disease, a hybrid disease with additional ridge tissue, and APROP in bigger babies with birth weight greater than 1500 g. Laser photocoagulation role is limited by the resultant visual field loss and high refractive error. Although anti-vascular endothelial growth factor injection allows peripheral retinal vascularization; reactivation of disease, systemic absorption of the drug and long-term safety are the chief concerns. Early vitrectomy is required when tractional retinal detachment develops. The visual outcome depends upon the morphology and vascular development of the macula. With the limited yet emerging new understanding of the pathophysiology, a multifaceted rational and individualized treatment strategy is suggested for APROP. Best practices in neonatal intensive care may prevent the occurrence of APROP. Further studies need to be performed for the prevention and safe, effective management of APROP.

Abstract
OBJECTIVE To report the morphological spectrum and outcome after laser treatment in posterior zone I retinopathy of prematurity. DESIGN Retrospective, consecutive, interventional case series. METHODS Review of charts and RetCam images of preterm infants with posterior zone I retinopathy of prematurity (defined as area within a circle, the radius of which extends from the center of the optic disc to the center of the macula) treated with confluent laser at a tertiary care referral institute between January 2006 and December 2015. Data was analyzed and tabulated using frequency and descriptive statistics to describe the demography, morphology, and outcome after laser treatment. RESULTS Fifty-six eyes (28 infants) with a mean gestational age of 28.65 ± 2.18 weeks and birth weight of 1153.04 ± 251.51 g were analyzed. Forty-two (75%) eyes had persistent tunica vasculosa lentis and 25 (44.6%) had preretinal hemorrhages. All eyes had circumferential ROP and a poorly developed foveal vasculature. Four distinct morphological patterns were encountered: I - typical aggressive posterior retinopathy was seen in 36 (64.3%) eyes; II - atypical aggressive posterior retinopathy (14 eyes; 25%) had raised fibrovascular proliferation always on the nasal retina close to the optic disc; III - hybrid retinopathy of prematurity (4 eyes; 8.7%) had a mat-like fibrous proliferation on vascularized posterior retina; and IV - threshold retinopathy of prematurity seen in 2 (4.4%) eyes. An unfavourable outcome was seen in 44 (78.6%) eyes. CONCLUSIONS Retinopathy of prematurity in posterior zone I presents with atypical morphology and poor outcomes despite confluent laser photocoagulation.

Abstract
Paediatric retinal detachment (PRD) is an uncommon and challenging disease; it differs from adult detachments in etiology, anatomical characteristics, management and prognosis. PRDs can be particularly challenging, even for the most expert paediatric surgeons due to the higher prevalence of total retinal detachments, late diagnosis and bilateral involvement with respect to those which occur in adulthood. Moreover, the anatomical success, when achieved, is frequently not related to a functional recover. Postsurgical adverse events, refractive errors and amblyopia may additionally undermine the final outcome. Up to date there are few reviews regarding the approach of retinal detachment in children, mainly dealing with rhegmatogenous retinal detachment. In this review, rhegmatogenous, retinopathy of prematurity-related and Coats'-related PRDs were considered. The available literature from the last decades were reviewed and summarized. Epidemiology, etiology and clinical presentation, together with therapeutic approaches and outcomes have been reviewed and discussed.

Abstract
PURPOSE To compare single versus 2-session laser photoablation for flat neovascularization in cases with Zone 1 aggressive posterior retinopathy of prematurity. METHODS Twenty-nine Asian Indian infants with aggressive posterior retinopathy of prematurity were randomized; each eye received 1 of 2 methods (29 each in Group A or B) proposed by the PHOTO-ROP group. Group A underwent single session laser to the avascular retina underlying the flat neovascularization by direct laser over the fronds. Group B underwent laser in 2 sessions; first, laser was delivered to the avascular periphery up to the flat neovascularization and 7 days later to the avascular bed exposed by the retraction of the fronds. Outcome and complications between the two groups were compared. RESULTS Mean birthweight and gestational ages were 1,276 g and 30.1 weeks, respectively. All eyes showed favorable outcome at a minimum 12-month follow-up. Hemorrhages after laser (41.4% vs. 17.2%, P < 0.001) were more common in the single laser group. Large hemorrhages (>1 disk diameter) seen in Group A took longer than 8 weeks to resolve and developed focal fibrosis. CONCLUSION This study demonstrates that the two-staged laser procedure produces fewer and smaller hemorrhages and no fibrosis compared with a single session. Both methods have comparable favorable outcomes in Asian Indian infants.

Abstract
PURPOSE To analyze risk factors for retinal detachment in eyes with aggressive posterior retinopathy of prematurity (ROP) treated with confluent laser photocoagulation. DESIGN Retrospective, consecutive, interventional case series. METHODS Infants undergoing laser treatment for aggressive posterior ROP from January 2006 through June 2010 participated. Eyes with retinal detachment (stage 4A, 4B, and 5) at presentation and those lost to follow-up after treatments were excluded. We defined 2 groups based on outcome after confluent laser photocoagulation: retinal detachment or favorable outcome. Two groups were compared for various factors, which included birth weight, gestational age, postconceptional age at laser treatment, zone of disease, preretinal hemorrhage, pre-existing fibrovascular proliferation, tunica vasculosa lentis, laser spots used for primary treatment, need for repeat laser treatment, and new-onset fibrovascular proliferation after laser treatment. Data were analyzed using univariate and multivariate logistic regression analysis. RESULTS One hundred nineteen eyes of 61 infants underwent laser treatment for aggressive posterior ROP. Ten (8.4%) eyes were excluded and 109 eyes (91.6%) were included. Nineteen (17.4%) of 109 eyes progressed to retinal detachment after laser treatment. On univariate analysis, multiple factors were associated with retinal detachment. Of these, all eyes with posterior zone 1 disease and all eyes demonstrating extensive fibrovascular proliferation (> 3 clock hours) after laser treatment progressed to retinal detachment. On multivariate logistic regression analysis, the most significant predictors of retinal detachment were gestational age of less than 29.5 weeks (P = .006), hemorrhages (P = .003), need for repeat laser treatment (P = .006), and new-onset limited fibrovascular traction (< 3 clock hours) after laser treatment (P = .042). CONCLUSIONS A gestational age of less than 29.5 weeks, posterior zone 1 disease, and preretinal hemorrhages before laser treatment are the most significant risk factors for retinal detachment in aggressive posterior ROP. Of the events occurring after laser treatment, new-onset fibrovascular traction is associated significantly with development of retinal detachment.

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.

Abstract
PURPOSE To evaluate outcomes of intravitreal injection of bevacizumab for the treatment of severe retinopathy of prematurity (ROP) associated with vitreous or retinal hemorrhages (VH or RH). METHODS This is a prospective interventional case-series. Fourteen eyes of eight premature infants with severe ROP associated with vitreous or retinal hemorrhage were consecutively included. In eight eyes, VH and/or RH precluding complete laser ablation developed at the time of laser treatment. In six eyes, VH developed early after laser ablation. All participants underwent intravitreal injection of 0.625 mg (0.025 ml) bevacizumab immediately after diagnosis of VH or RH. Follow-up examinations were performed at days 1, 3, 7, and 14, and 1, 2 and 3 months after injection. Main outcome measure was the absence of unfavorable structural outcomes. RESULTS Mean gestational age was 27.6 weeks (range, 26-29 weeks) and mean birth weight was 1047 g (range, 780-1500 g). Mean gestational age at the time of injection was 35.4 weeks (range, 32-38 weeks). In all eyes, plus disease disappeared completely within 2 weeks and VH and/or RH was absorbed at last follow-up. None of the eyes developed unfavorable structural outcomes. No eyes needed additional injection or laser treatment. No major systemic or ocular complications were observed. CONCLUSION In this small series of patients, intravitreal injection of bevacizumab was effective for treatment of severe retinopathy of prematurity associated with vitreous or retinal hemorrhage.

OBJECTIVE To assess the effect of early vitrectomy for aggressive posterior retinopathy of prematurity (APROP) using fundus fluorescein angiography. DESIGN Retrospective, observational case series. PARTICIPANTS Eleven eyes of 7 patients with APROP that underwent early vitreous surgery. METHODS All eyes underwent vitrectomy with lensectomy that removed the vitreous gel around the fibrovascular proliferative tissue, but not the proliferative tissue when fibrovascular proliferation and retinal detachment occurred despite retinal photocoagulation. Fundus fluorescein angiography was performed before and after the early vitreous surgery. MAIN OUTCOME MEASURES Dye leakage from the fibrovascular tissue, dilation and tortuosity of the retinal vasculature, and shunt vessels were evaluated by fundus fluorescein angiography. The status of the retinal reattachment was assessed postoperatively. RESULTS Nine eyes had severe dye leakage from the fibrovascular tissue and 2 eyes had moderate leakage seen by preoperative fluorescein angiography. Severe dilation and tortuosity of the retinal vessels were detected in 10 eyes and shunt vessels in 7 eyes. Six to 12 days after successful surgery, the retina reattached and dilation and tortuosity of the retinal vessels decreased substantially. Dye leakage diminished markedly in all eyes, resolved completely in 7 eyes, and was still apparent slightly in 4. At the final examination, fibrovascular proliferation and retinal detachment did not progress in any eyes; however, 2 eyes had a dragged or folded retina. Follow-up ranged from 6 to 19 months (mean, 9.2). CONCLUSIONS Early vitrectomy that removes vitreous gel from around the proliferative tissue promptly reduces vascular activity and may limit progression of retinal detachment in APROP.

Abstract
PURPOSE OF REVIEW The surgical management of retinopathy of prematurity continues to employ a paradigm of peripheral laser followed by vitrectomy for patients who develop retinal detachment. This review addresses significant advances that have been made in our understanding of the indications, timing, techniques, and outcomes of these interventions. RECENT FINDINGS The indications for laser are highly dependent on the diagnosis of plus disease. Recognition of plus disease is variable and subjective. Efforts are underway to develop more objective measures of plus using image analysis software. Intravitreal injection of bevacizumab is emerging as an adjunct to laser for aggressive posterior retinopathy of prematurity. Although vitrectomy for retinal detachment is effective in eyes without plus, management of eyes with retinal detachment and persistent plus continues to be a major challenge. Older children with regressed retinopathy of prematurity may suffer from vitreous hemorrhage in the absence of retinal tears, detachments, or active neovascularization. SUMMARY Our understanding of the best indications, timing, and techniques for the surgical management of retinopathy of prematurity continues to evolve and outcomes have improved in recent years. Areas that generate significant ongoing interest and investigation include the assessment of plus disease and the use of adjuncts for aggressive posterior retinopathy of prematurity.
