RESUMEN
Persistent fetal vasculature (PFV) is a rare ocular developmental disorder resulting from incomplete apoptosis of the embryonic hyaloid vasculature during the in-utero period. Variability in the development and regression of hyaloid vasculature is responsible for the wide range of clinical presentation of the disorder. PFV may manifest as anterior segment abnormalities (cataract, glaucoma, microphthalmia, elongated ciliary process with central traction, retrolental membrane, and shallow anterior chamber), posterior segment abnormalities (vitreous stalk, preretinal membranes, optic hypoplasia, and retinal folds), or with a combined anteroposterior disease. The most common associated clinical feature is leukocoria with microphthalmia and usually unilateral presentation. Most of the cases have poor visual prognosis and present early in childhood. Association with myopia is a very rare and atypical presentation, especially unilateral cases which may present later in life and have a good visual prognosis. Hereby, we present a case of a 27-year-old young adult male with unilateral atypical myopic posterior PFV with anisometropic amblyopia and good functional vision in the right eye.
RESUMEN
Persistent fetal vasculature (PFV), or persistent hyperplastic primary vitreous (PHPV), is a congenital developmental disorder characterized by a failure of resorption of the hyaloid system. It typically presents unilaterally and has three forms: anterior, posterior, and mixed. In this case report, a seven-year-old patient, without specific personal or family medical history, was referred from the pediatric department for bilateral papilledema. The patient had a best-corrected visual acuity of 20/20 (Logarithmic Measure of Angle of Resolution (LogMAR): 0) in both eyes. Fundus examination of both eyes revealed congested pseudopapilledema with a short, mobile, brownish band extending from the optic disc towards the vitreous cavity. Ocular ultrasound of both eyes showed a fine hyperechoic line pulling on the optic nerve head, and papillary optical coherence tomography (OCT) showed a papillary traction syndrome. The diagnosis of a posterior and bilateral form of persistent fetal vasculature with papillary traction was established.
RESUMEN
Purpose: To report a case of oculo-facio-cardio-dental (OFCD) syndrome secondary to a novel BCOR variant in a pediatric patient with congenital cataracts, microphthalmia, persistent fetal vasculature (PFV), focal chorioretinal hyperpigmentation, peripheral retinal avascularity, and foveal photoreceptor atrophy. Observations: A 3-month-old female patient was referred for bilateral congenital cataracts with microphthalmia. Her past medical history was significant for syndactyly of the toes, left bifid rib, atrial septal defect, patent ductus arteriosus, mitral regurgitation, pulmonary hypertension, anemia of prematurity, vesicoureteral reflux, and duodenal atresia. Examination under anesthesia revealed persistent fetal vasculature (PFV) with peripheral avascularity, foveal photoreceptor atrophy, and focal chorioretinal hyperpigmentation. A bilateral lensectomy with anterior vitrectomy and posterior capsulotomy were performed. Genetic testing identified a novel heterozygous pathogenic variant in the BCOR gene (c.1612C > T (p.Gln538Ter)), confirming a diagnosis of OFCD syndrome. Conclusions and importance: This case describes novel posterior segment findings in a patient with OFCD. A detailed examination of both anterior and posterior segments in combination with multimodal imaging should be performed in patients suspected of having OFCD, as this may be critical in determining visual potential and appropriate surgical management.
RESUMEN
BACKGROUND AND PURPOSE: Persistent fetal vasculature (PFV) is a complex congenital ocular condition, characterized by the incomplete regression of the embryonic hyaloid system. It encompasses a spectrum of abnormalities, affecting various ocular structures and presenting a range of fetal hyaloid remnants. Despite its long-standing recognition, the full extent of PFV's manifestations continues to evolve, unveiling novel findings, primarily driven by advancements in clinical experience and imaging techniques. This review focuses on the evolution of PFV management, emphasizing the disease heterogeneity and the consequent challenges in diagnosis and treatment. METHODS: We present a comprehensive guide on PFV based on the current evidence, detailing its recognition, associated anatomical variations, the intricacies of surgical indications and techniques, and postoperative expectations. CONCLUSION: The progress over the last decade in innovative instruments and surgical techniques has not only enhanced functional and anatomical outcomes but also enriched our understanding of PFV. However, continued exploration and research remain pivotal for future breakthroughs in more effectively understanding and managing this complex ocular anomaly.
RESUMEN
Congenital cataract is among the main causes of treatable vision loss in childhood. The first weeks and months of life are a critical time for the development of vision. Therefore, early cataract surgery and effective multifaceted treatment of the resulting aphakia in the early stages of life are of great value for the management of vision development. Among the treatment models, contact lenses (CL) have an important place in infancy and early childhood up to the age of 2 years. Although good visual gains were not considered very likely, especially in unilateral aphakia, important steps have been taken in the treatment of pediatric aphakia thanks to the surgical techniques developed over time and the increasing experience with optical correction systems, especially CLs. This review examines current developments in the types of CL used in pediatric aphakia, their application features, comparison with other optical systems, the features of amblyopia treatment in the presence of CL, and the results obtained with family compliance to CL wear and occlusion therapy in the light of existing studies.

Persistent fetal vasculature is a spectrum of ocular abnormalities linked to an incomplete regression of the fetal ocular vasculature. A 21-years old male patient came to the outpatient clinic reporting low vision and strabismus in his left eye since 3 years of age. Ophtalmological examination revealed a normal right eye, while the left eye had a best corrected visual acuity of hand-motion perception, a 30 prism diopters esotropia, a "coralliform" cataract and a vitreous stalk joining the posterior face of the lens and the optic nerve. The coralliform cataract possessed spindle-shaped processes radiating out of its center in an axial direction and was located in the posterior subcapsular area. The patient elected to not undergo vitreoretinal surgery due to the poor visual prognosis. The unusual cataract present in the described patient could be related to his untreated status, as previous authors have reported that untreated cataracts in persistent fetal vasculature may undergo diverse degenerations.

Pediatric retinal vascular diseases are a spectrum with overlapping phenotypes and related genes. Retinal vascular development is biphasic. Vasculogenesis is responsible for the formation of primordial vessels leading to the four major arcades in the posterior retina. Angiogenesis, which is vascular endothelial growth factor dependent, is responsible for the formation of new vessels through budding from existing vessels, forming the peripheral vessels, increasing the capillary density of the central retina, and forming the superficial and deep capillary plexus. This process is controlled by WNT signaling, which is important for cell proliferation, division, and migration. Disorders of WNT signaling, such as familial exudative vitreoretinopathy (FEVR), have overlapping clinical findings. Conversely, pathogenic variants in some of the FEVR-related genes are reported in conditions such as retinopathy of prematurity (ROP), persistent fetal vasculature, and Coats disease. The various overlapping features and underlying genetic basis in the pathogenesis of pediatric retinal vascular developmental diseases suggest that genetic variants may provide a framework or a background for these conditions, upon which further insults can affect the development at any phase (such as prematurity and oxygenation in ROP), influencing and determining the final phenotype.
RESUMEN
PURPOSE: To describe abnormalities of the optic nerve microvasculature in patients with persistent fetal vasculature (PFV) and their fellow eyes using OCT angiography (OCTA). DESIGN: Cross-sectional study. SUBJECTS: Fifty eyes of 25 patients with PFV who underwent prospective imaging using supine OCTA during examination under anesthesia at Bascom Palmer Eye Institute from March 1, 2019, to December 31, 2022. METHODS: OCT angiography images of the optic nerve of the included patients were analyzed with a primary focus on blood flow. Demographic, clinical, and treatment factors were compared with morphologic changes in the optic disc microvasculature. MAIN OUTCOME MEASURES: Prevalence of optic nerve microvascular abnormalities on OCTA in the affected and fellow eyes of patients with PFV. RESULTS: A total of 50 eyes from 25 patients were reviewed, and 28% (7/25) met image quality criteria for OCTA analysis. Optic nerve OCTA showed a persistent hyaloid artery (PHA) in all (7/7) PFV eyes analyzed. Of these, flow on OCTA was detectable in 57% (4/7). A Bergmeister papilla was evident in 100% (25/25) fellow eyes, of which flow was detected in 68% (17/25). Fluorescein angiography (FA) demonstrated blood flow within the stalk in 40% (10/25) of PFV eyes and within the Bergmeister papilla in 25% (6/25) of fellow eyes. Similar findings of abnormal blood flow and presence of fibrovascular stalk were seen in both treatment-naïve and treated groups. CONCLUSIONS: OCT angiography allows for high-resolution visualization of subtle vascular abnormalities that are not readily apparent using RetCam FA and may serve as a useful noninvasive test to confirm the patency of the PHA and Bergmeister papilla in children. The results of the present study suggest that PFV may be a bilateral and asymmetric process.

BACKGROUND: Blau Syndrome (BS) is a rare autosomal dominant noncaseous granulomatous disease caused by mutations in the NOD2 gene. The disease is characterized by granulomatous dermatitis, symmetrical arthritis, and uveitis, which, if left untreated, can progress to blindness. The diagnosis of BS can be challenging because of its rarity and overlap with other rheumatologic disorders. Early detection of ocular involvement is critical to prevent vision loss and improve the prognosis of patients with BS. CASE PRESENTATION: In this report, we present a case of a five-year-old Chinese girl diagnosed with BS one year ago after presenting with a systemic rash and urinary calculi. Genetic testing was recommended by a physician, and a heterozygous mutation of the NOD2 gene c.1538T > C (p.M513T) was identified. Eight months ago, due to bilateral corneal punctate opacity, we had examined and diagnosed bilateral uveitis, bilateral corneal zonal degeneration, persistent fetal vasculature (PFV) in the right eye, and perivascular granuloma in the right eye. As a result, Vitrectomy was performed on the right eye, resulting in a significant improvement in visual acuity from 1/50 on the first day after surgery to 3/10 after 1 week. After 6 months, the visual acuity of the right eye was maintained at 3/20, but opacification of the lens posterior capsule was observed. Follow-up appointments are ongoing to monitor the condition of the affected eyes. Our report underscores the importance of prompt detection and management of ocular involvement in BS accompany with PFV to prevent vision loss and improve patient outcomes. CONCLUSIONS: This report details the case of a child diagnosed with BS who accompanied a periretinal granuloma and PFV in the right eye. Regrettably, the left eye was observed to have no light perception (NLP) with the fundus not being visible. The occurrence of ocular complications in patients with BS, must be closely monitored to prevent vision loss and enhance treatment outcomes. This case underscores the importance of prompt diagnosis and management of ocular complications in patients with BS to prevent further damage and optimize patient outcomes.

PURPOSE: This study aims to investigate surgical outcomes of eyes with severe anterior persistent fetal vasculature (PFV) and the role of associated anatomical anomalies on prognosis. METHODS: This is a retrospective, comparative case series of 32 eyes of 31 patients who underwent vitreoretinal surgery for severe anterior PFV, defined as fibrovascular tissue totally covering the back of cataractous lens. Based on the degree of anterior retinal elongations, cases were classified as follows: group 1, eyes with well-developed pars plana and minor/no abnormalities (n = 11, 34%); group 2, eyes with partially developed pars plana and broad-based elongations (n = 9, 28%); and group 3, eyes with no visible pars plana and fibrovascular membrane having 360° continuity with peripheral retina (n = 12, 38%). Complications and functional and anatomical outcomes were investigated. RESULTS: The median surgical age was 2 (1-12) months. The median follow-up was 26 (6-120) months. Seventy-three percent in group 1 achieved finger counting or better vision with a single surgery and without any pupillary/retinal complication. Groups 2 and 3 required 2.1 ± 0.9 and 2.6 ± 1.2 surgeries on average. Pupillary obliteration and RD occurred in 33% and 22% in group 2 and 58% and 67% in group 3. Retina remained attached after silicone oil removal in 89% of group 2 and 25% of group 3. Phthisis developed in 50% in group 3. CONCLUSION: Peripheral retinal anomalies are common in severe anterior PFV and have a major impact on prognosis. Prognosis is favorable in cases with mild-to-moderate anomalies with appropriate management of possible retinal tears. In eyes with 360° retinal elongations, severe fibrous proliferation and eventual eye loss are common.

PURPOSE: To describe clinical features, management, and outcomes of posterior persistent fetal vasculature (PFV) and suggest a management algorithm. DESIGN: Retrospective, consecutive case series. PARTICIPANTS: All children diagnosed with posterior PFV and treated or followed at the Rothschild Foundation Hospital in France between June 2011 and September 2021. METHODS: Retrospective analysis of the clinical characteristics of posterior PFV. We reported age, gender, presenting symptoms, intraocular pressure, and visual acuity (VA) at diagnosis. Patients were divided into 4 groups depending on the severity and involvement or not of anterior segment. We reported the vitreoretinal surgical techniques used. MAIN OUTCOME MEASURES: Anatomic results, ocular hypertension, best-corrected distance visual acuity (BCDVA), presence of postoperative adverse events, and additional surgical interventions were recorded at each follow-up visit. RESULTS: Ninety-six patients were included. The median age at diagnosis was 8 months (IQR = 12), mean 18.9 ± 30.9 months) with a mean follow-up of 27 ± 31.2 months. Although PFV is often an isolated disease, it was associated with a systemic disease in 8% of cases. There was anterior involvement in 62 (64%) of eyes. Forty-one eyes (42.7%) were microphthalmic and more frequently associated with severe PFV (53% vs. 25%; P = 0.01). Surgery was performed in 85 patients (89%). Of them, 69 (81%) had a total success, 5 (6%) had a partial success due to persistent limited peripheral retinal detachment (RD), and 11 (13%) had a failure due to persistent total RD after surgery. Postoperative adverse events occured in 38 eyes including ocular hypertension requiring eye drop medication (7.1%), secondary cell proliferation around the intraocular lens (8.2%), intravitreal hemorrhages (7.1%), and persistent tractional RD (10.6%). Second surgery was performed in 18 patients (21%). At last follow-up, VA could be measured in logarithm of the minimum angle of resolution in 43 children (45%), light perception in 21 eyes (22%), and no light perception or impossible to assess in 32 eyes (33%). CONCLUSIONS: In our case series, most patients presenting with posterior PFV received complex vitreoretinal surgery. Goals of the surgery vary and include retinal flattening, reduction of vitreoretinal traction, freeing of visual axis, and aesthetic concerns. We propose a surgical and medical management algorithm for PFV. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

Purpose: To determine the cumulative incidence of strabismus surgery after pediatric cataract surgery and identify the associated risk factors. Design: US population-based insurance claims retrospective cohort study. Participants: Patients ≤ 18 years old who underwent cataract surgery in 2 large databases: Optum Clinformatics Data Mart (2003-2021) and IBM MarketScan (2007-2016). Methods: Individuals with at least 6 months of prior enrollment were included, and those with a history of strabismus surgery were excluded. The primary outcome was strabismus surgery within 5 years of cataract surgery. The risk factors investigated included age, sex, persistent fetal vasculature (PFV), intraocular lens (IOL) placement, nystagmus and strabismus diagnoses before cataract surgery, and cataract surgery laterality. Main Outcome Measures: Kaplan-Meier estimated cumulative incidence of strabismus surgery 5 years after cataract surgery and hazard ratios (HRs) with 95% confidence intervals (CIs) from multivariable Cox proportional hazards regression models. Results: Strabismus surgery was performed on 271/5822 children included in this study. The cumulative incidence of strabismus surgery within 5 years after cataract surgery was 9.6% (95% CI, 8.3%-10.9%). Children who underwent strabismus surgery were more likely to be of younger age at the time of cataract surgery, of female sex, have a history of PFV or nystagmus, have a pre-existing strabismus diagnosis, and less likely to have an IOL placed (all P < 0.001). Factors associated with strabismus surgery in the multivariable analysis included age 1 to 4 years (HR, 0.50; 95% CI, 0.36-0.69; P < 0.001) and age > 5 years (HR, 0.13; 95% CI, 0.09-0.18; P < 0.001) compared with age < 1 year at time of cataract surgery, male sex (HR, 0.75; 95% CI, 0.59-0.95; P < 0.001), IOL placement (HR, 0.71; 95% CI, 0.54-0.94; P = 0.016), and strabismus diagnosis before cataract surgery (HR, 4.13; 95% CI, 3.17-5.38; P < 0.001). Among patients with strabismus diagnosis before cataract surgery, younger age at cataract surgery was the only factor associated with increased risk of strabismus surgery. Conclusions: Approximately 10% of patients will undergo strabismus surgery within 5 years after pediatric cataract surgery. Children of younger age, female sex, and with a pre-existing strabismus diagnosis undergoing cataract surgery without IOL placement are at greater risk.

PURPOSE: To describe a case of Bilateral Morning Glory Syndrome (MGS) associated with Unilateral Persistent Fetal Vasculature (PFV) in a 3-day old neonate. OBSERVATIONS: A 3-day-old neonate was found bilateral retinal abnormalities due to neonatal eye screening. Dilated fundus exam showed bilateral optic disc dysplasia with the persistent hyaloid vessels in right eye at first. With the progress of the disease, optic disc was enlarged with central umbilication which with a similar anomalous radiating peripapillary vascular appearance, the persistent hyaloid vessels in vitreous cavity of right eye gradually disappear, a large amount of exudation can be seen in the posterior pole retina with macular movement in both eyes. Bilateral vitrectomy was performed in this case, then the condition of the neonate's both eyes is stable until 1 year old. CONCLUSIONS AND IMPORTANCE: This is a rare case that showing the development of MGS and PFV and the relationship between these two diseases. In addition, we completely observed the whole process of the change of the persistent hyaloid vessels in the vitreous cavity of a case of MGS associated with PFV.
RESUMEN
Persistent fetal vasculature (PFV) is a rare malformative ocular disorder resulting from the failure of the hyaloid vasculature to regress. The severity of the visual impairment is depending on the underlying eye defects, ranging from discreet hyaloid remnants to severe ocular anomalies. Although PFV is generally unilateral, sporadic and idiopathic, a genetic cause has been described in some individuals, especially those presenting with a bilateral and/or syndromic form of PFV. The genes occasionally described in PFV are most often responsible for a wide spectrum of ocular phenotypes such as ATOH7 or NDP, a gene also known to be involved in Norrie disease, a X-linked vitreoretinopathy with extra-ocular features. We describe here a patient with an ocular phenotype consisting in non-syndromic bilateral PFV with cataract and microphthalmia, in whom a recurrent heterozygous de novo MIP disease-causing variant was detected after using a dedicated 119-ocular genes panel approach. Defects in the MIP gene are classically associated with dominant non-syndromic congenital cataract without other ocular malformative features. Thus, this case highlights the value of exploring individuals with PFV, even those with non-syndromic forms. It also broadens the phenotypic spectrum of the MIP gene, adding new insights into the gene networks underlying PFV pathophysiology, that remains unclear.

AIM: To study the different types and frequency of pseudoretinoblastoma (pseudoRB) lesions who present to a retinoblastoma centre due to concern that the condition may be retinoblastoma. METHODS: A retrospective chart review of 341 patients presenting sporadically to the Royal London Hospital from January 2009 to December 2018. RESULTS: 220 patients (65%) were confirmed to have retinoblastoma, while 121 (35%) had pseudoRB. There were 23 differential diagnoses in total. The top 3 differential diagnoses were Coats' disease (34%), Persistent Foetal Vasculature (PFV) (17%) and Combined Hamartoma of Retina and Retinal Pigment Epithelium (CHR-RPE) (13%). PseudoRBs differed with age at presentation. Under the age of 1 (n = 42), the most likely pseudoRB conditions were PFV (36%), Coats' disease (17%) and CHR-RPE (12%). These conditions were also the most common simulating conditions between the ages of 1 and 2 (n = 21), but Coats' disease was the most common in this age group (52%), followed by CHR-RPE (19%) and PFV (14%). Between the ages of 2 and 5 (n = 32), Coats' disease remained the most common (44%) pseudoRB lesion followed by CHR-RPE (13%), or PFV, Retinal Astrocytic Hamartoma (RAH), familial exudative vitreoretinopathy (FEVR) (all 6.3%). Over the age of 5 (n = 26), pseudoRBs were most likely to be Coats' disease (35%), RAH (12%), Uveitis, CHR-RPE, FEVR (all 7.7%). CONCLUSION: 35% of suspected retinoblastoma cases are pseudoRB conditions. Overall, Coats' disease is the most common pseudoRB condition, followed by PFV. Hamartomas (CHR-RPE & RAH) are more prevalent in this cohort, reflecting improvements in diagnostic accuracy from referring ophthalmologists.

PURPOSE: To investigate the distribution of pseudoretinoblastoma (PSRB) cases based on gender, age, and laterality. MATERIALS AND METHODS: The clinical records of 607 patients (851 eyes) who were referred for diagnosis of retinoblastoma or simulating conditions between October 1998 and May 2021 were retrospectively evaluated. Patients were stratified by age as follows: ≤1 year, >1-3 years, >3-5 years, and >5 years. RESULTS: Of 190/607 PSRB patients, 129 (67.9%) were males and 61 (32.1%) females (p = 0.001). The 3 most common diagnoses in males were Coats disease (20.2%), persistent fetal vasculature (PFV, 14.0%), and chorioretinal coloboma (6.2%). In females, the 3 most common diagnoses included PFV (21.3%), retinal dysplasia, congenital glaucoma, and combined hamartoma (each 6.6%). PFV was the most common diagnosis in ≤1 year old patient group (26.6%). Coats disease and PFV were the most common diagnoses in >1-3 years old patient group (each 16.7%). Coats disease was the most common diagnosis in >3-5 years old (30.8%) and >5 years old patient groups (13.1%). PSRBs were unilateral in 121/190 (63.7%) patients. Coats disease usually presented unilaterally (p < 0.001) while PFV, optic nerve head drusen, and retinopathy of prematurity as bilateral diseases (p = 0.019, p = 0.001, and p = 0.001 respectively). DISCUSSION: PSRB diagnoses show differences depending on gender, age, and laterality. In our study, the most common PSRB lesions were Coats disease in males and PFV in females. PFV was the most frequent diagnosis in ≤3 years and Coats disease in >3 years of age groups. Coats disease and PFV were the most common unilateral and bilateral PSRB diagnoses respectively.

AIM: To analyze the similarities and differences of the clinical features between persistent hyperplastic primary vitreous(PHPV)and congenital fibrovascular pupillary membrane(CFPM).METHODS: Retrospectively analyze the ocular biometric parameters, clinical features and morphological changes in children with PHPV(PHPV group)and CFPM(CFPM group)who received surgery at the department of ophthalmology, Xijing Hospital from March 2006 to December 2021.RESULTS: The study included 56 cases(61 eyes)of PHPV and 24 cases(25 eyes)of CFPM. There were no differences on the gender and age of onset between PHPV and CFPM, and both of them were mainly unilaterally affected, with the ratio of 91% and 96%. Children with PHPV and cataract combined with other complications and ocular developmental abnormalities. CFPM was mainly presented different degrees of blockage and morphological abnormalities of pupillary area. In unilateral cases of PHPV and CFPM, the anterior chamber depth(ACD)of affected eyes was smaller than that of the fellow eyes, and in subgroups with age of operation ≤24mo, the axial length(AL)of affected eyes was smaller than that of the fellow eyes(P<0.05). The corneal diameter(CD)of the affected eyes in PHPV group was smaller and the intraocular pressure(IOP)was higher than those of the fellow eyes(all P<0.05); while there were no significant differences on CD and IOP between affected eyes and the fellow eyes in CFPM group(P&#x003E;0.05). The ACD of affected eyes in PHPV group was significantly smaller than that of CFPM group(P<0.05). The fibrovascular membrane in PHPV group was located in the posterior part of the lens and vitreous cavity; while the fibrovascular membrane in CFPM group was located between the iris and the anterior capsule of the lens, rarely involving the lens.CONCLUSION: PHPV and CFPM had the similar clinical features, suggesting that they may belong to the different variants of persistent fetal vasculature(PFV). However, PHPV had a wider range of lesions and more complex conditions.
RESUMEN
Purpose: To determine the cumulative incidence of retinal detachment (RD) repair following pediatric cataract surgery and identify the associated risk factors. Design: US population-based insurance claims retrospective cohort study. Participants: Patients ≤ 18 years old who underwent cataract surgery in 2 large databases: Optum Clinformatics (2003-2021) and IBM MarketScan (2007-2016). Methods: Individuals with ≥ 6 months of prior enrollment were included, and those with a history of RD, RD repair, traumatic cataract, spherophakia, or ectopia lentis were excluded. The primary outcome was time between initial cataract surgery and RD repair. The risk factors investigated included age, sex, persistent fetal vasculature (PFV), prematurity, intraocular lens (IOL) placement, and pars plana lensectomy approach. Main Outcome Measures: Kaplan-Meier estimated cumulative incidence of RD repair 5 years after cataract surgery and hazard ratios (HRs) with 95% confidence intervals (CIs) from multivariable Cox proportional hazards regression models. Results: Retinal detachment repair was performed on 47 of 3289 children included in this study. The cumulative incidence of RD repair within 5 years of cataract surgery was 2.0% (95% CI, 1.3%-2.6%). Children requiring RD repair were more likely to have a history of prematurity or PFV and less likely to have an IOL placed (all P < 0.001). Factors associated with RD repair in the multivariable analysis included a history of prematurity (HR, 6.89; 95% CI, 3.26-14.56; P < 0.001), PFV diagnosis (HR, 8.20; 95% CI, 4.11-16.37; P < 0.001), and IOL placement (HR, 0.44; 95% CI, 0.21-0.91; P = 0.03). Age at surgery, sex, and pars plana lensectomy approach were not significantly associated with RD repair after adjusting for all other covariates. Conclusions: Approximately 2% of patients will undergo RD repair within 5 years of pediatric cataract surgery. Children with a history of PFV and prematurity undergoing cataract surgery without IOL placement are at the greatest risk.
