Wagner syndrome: Novel VCAN variant and prophylactic management with encircling band and retinopexy. Am J Ophthalmol Case Rep 2024; 34:102061. [PMID: 38680526 PMCID: PMC11046050 DOI: 10.1016/j.ajoc.2024.102061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 03/09/2024] [Accepted: 04/05/2024] [Indexed: 05/01/2024] Open
Abstract
Purpose Wagner syndrome is an autosomal genetic vitreoretinopathy characterized by chorioretinal atrophy, avascular vitreous veils, reduced visual acuity and early retinal detachment in advanced cases. Management of Wagner syndrome usually results in observation then management of occurring complications. Observations We report the case of a 9-year-old girl presenting with supposed Wagner syndrome that we managed with prophylactic encircling band and retinopexy in both eyes. The genetic testing revealed a new variant in the intron 7 non canonical splice acceptor site, c.4004-12_4004-6delins17, that was also present in her father. Conclusions and Importance The VCAN variant found in this proband and her father has not been described yet but shows high predictions of pathogenicity. The previous reported variants in VCAN intron 7 and the associated phenotype for both cases allowed us to attribute this variant to Wagner syndrome. In Wagner syndrome, management is usually curative. After prophylactic surgery in our case, the zones of retinal delamination were well supported by the scleral buckle, releasing the vitreoretinal tractions, and the additional laser focalized on the temporal zones of dehiscence secured the retina. An encircling band may be a good way to prevent RD in patients with Wagner syndrome at risk.

Deep Learning for prediction of late recurrence of retinal detachment using preoperative and postoperative ultra-wide field imaging. Acta Ophthalmol 2024. [PMID: 38682863 DOI: 10.1111/aos.16693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Accepted: 04/08/2024] [Indexed: 05/01/2024]
Abstract
PURPOSE To elaborate a deep learning (DL) model for automatic prediction of late recurrence (LR) of rhegmatogenous retinal detachment (RRD) using pseudocolor and fundus autofluorescence (AF) ultra-wide field (UWF) images obtained preoperatively and postoperatively. MATERIALS AND METHODS We retrospectively included patients >18 years who underwent either scleral buckling (SB) or pars plana vitrectomy (PPV) for primary or recurrent RRD with a post-operative follow-up >2 years. Records of RRD recurrence between 6 weeks and 2 years after surgery served as a ground truth for the training of the deep learning (DL) models. Four separate DL models were trained to predict LR within the 2 postoperative years (binary outputs) using, respectively, UWF preoperative and postoperative pseudocolor images and UWF preoperative and postoperative AF images. RESULTS A total of 412 eyes were included in the study (332 eyes treated with PPV and 80 eyes with SB). The mean follow-up was 4.0 ± 2.1 years. The DL models based on preoperative and postoperative pseudocolor UWF imaging predicted recurrence with 85.6% (sensitivity 86.7%, specificity 85.4%) and 90.2% accuracy (sensitivity 87.0%, specificity 90.8%) in PPV-treated eyes, and 87.0% (sensitivity 86.7%, specificity 87.0%) and 91.1% (sensitivity 88.2%, specificity 91.9%) in SB-treated eyes, respectively. The DL models using preoperative and postoperative AF-UWF imaging predicted recurrence with 87.6% (sensitivity 84.0% and specificity 88.3%) and 91.0% (sensitivity 88.9%, specificity 91.5%) accuracy in PPV eyes, and 86.5% (sensitivity 87.5%; specificity 86.2%) and 90.6% (sensitivity 90.0%, specificity 90.7%) in SB eyes, respectively. Among the risk factors detected with visualisation methods, potential novel ones were extensive laser retinopexy and asymmetric staphyloma. CONCLUSIONS DL can accurately predict the LR of RRD based on UWF images (especially postoperative ones), which can help refine follow-up strategies. Saliency maps might provide further insight into the dynamics of RRD recurrence.

Intraocular foreign bodies in children: A retrospective case series. J Fr Ophtalmol 2024; 47:104188. [PMID: 38636198 DOI: 10.1016/j.jfo.2024.104188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 11/21/2023] [Accepted: 12/15/2023] [Indexed: 04/20/2024]
Abstract
INTRODUCTION Open globe injuries are a major cause of visual impairment in children, related to the severity of the trauma or secondary to induced amblyopia. Intraocular foreign bodies (IOFB) have been reported in approximately one third of cases of open globe injuries. As clinical presentation and management may differ between adults and children, data is lacking about IOFBs in children under 18years of age. The purpose of this study was to assess the clinical characteristics and visual prognosis of ocular trauma associated with intraocular foreign bodies in children. MATERIALS AND METHODS This single-center retrospective study included patients under 18years of age treated for ocular trauma with IOFB. Demographic characteristics, complete initial and final ophthalmological examination, imaging data and details of medical and surgical management were collected. RESULTS Fourteen patients were included (78.6% boys), with a mean age of 10.3years (min 7months-max 17years). In 92.9% of cases, patients were found to have a single IOFB, mostly metallic (71.4%). Posterior segment IOFBs were found in 50% of cases, anterior segment IOFBs in 28.6% and orbital IOFBs in 21.4%. The clinical examination permitted detection of the IOFBs in 50% of cases, while they were visible on CT scan in all cases. The mean initial visual acuity was 20/320, and the mean final visual acuity was 20/125. Endophthalmitis occurred in 2 cases (14%). DISCUSSION Open globe injuries associated with IOFB are severe and sight-threatening. Localization of the IOFB in the posterior segment has a worse prognosis. CT scan is mandatory, especially in children, as the trauma history is often missing. Retinal detachment and endophthalmitis appear to be the main prognostic factors requiring urgent specialized pediatric ophthalmology management.

Abstract
PURPOSE To describe the clinical characteristics, management, and outcomes of toddlers (under the age of 3) diagnosed with familial exudative vitreoretinopathy. METHODS In this retrospective study, patients diagnosed with familial exudative vitreoretinopathy before the age of 3 were included. Presenting characteristics, genetic testing, management, and outcomes were collected. RESULTS A total of 54 patients (108 eyes) with a mean age at diagnosis of 10.9 ± 2.6 months were included. Poor visual behavior (33%) and strabismus (26%) were the most common presenting symptoms, whereas screening only represented 11%. About half of included patients had a severe disease (stages 4 and 5). Genetic testing was positive in 40.7% of patients with 24% having a family history of familial exudative vitreoretinopathy. LRP5 was the most prevalent mutation (54.5%).Surgery was performed in 44.4% of eyes and was successful in 69.8% of cases. Failure exclusively occurred in eyes with severe stages. Among eyes evaluated for visual acuity (72 eyes), most (76.4%) had a vision of hand motion or better. CONCLUSION Familial exudative vitreoretinopathy tended to be worse with earlier age at diagnosis, subsequently affecting the prognosis. Surgical intervention was common and primarily included lens-sparing vitrectomy and combined lensectomy and vitrectomy. Surgical success hinged on the stage of the disease.

Natural History and Surgical Outcomes of Lamellar Macular Holes. Ophthalmol Retina 2024; 8:210-222. [PMID: 37743020 DOI: 10.1016/j.oret.2023.09.016] [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: 04/15/2023] [Revised: 09/09/2023] [Accepted: 09/18/2023] [Indexed: 09/26/2023]
Abstract
PURPOSE To assess the natural history and surgical outcomes of lamellar macular holes (LMHs). DESIGN Retrospective and consecutive case series. SUBJECTS Patients with LMHs from multiple tertiary care centers. METHODS Clinical charts and OCT scans were reviewed. MAIN OUTCOME MEASURES The visual acuity (VA) changes and the occurrence rate of full-thickness macular hole (FTMH) were studied in both groups. Within the operated group, factors associated with 6-month VA and development of FTMH were explored. RESULTS One hundred seventy-eight eyes were included, of which 89 were monitored and 89 underwent surgery. In the observation group, the mean VA decreased from 0.25 ± 0.18 to 0.28 ± 0.18 logarithm of the minimum angle of resolution (logMAR; P = 0.13), with 14 eyes (15.7%) that lost ≥ 0.2 logMAR VA, after 45.7 ± 33.3 months. Nine eyes (10.1%) spontaneously developed an FTMH. In the operated group, the mean VA increased from 0.47 ± 0.23 to 0.35 ± 0.25 logMAR at 6 months (P < 0.001) and 0.36 ± 0.28 logMAR (P = 0.001) after 24.1 ± 30.1 months. By multivariate analysis, better baseline VA (P < 0.001), the presence of an epiretinal membrane (P = 0.03), and the peeling of the internal limiting membrane (ILM; P = 0.02), with a greater effect of ILM perihole sparing, were associated with a greater 6-month VA. Perihole epiretinal proliferation sparing was associated with a better postoperative VA by univariate analysis (P = 0.03), but this was not significant by multivariate analysis. Eight eyes (9.0%) developed a postoperative FTMH. Using Cox proportional hazard ratios [HRs], pseudophakia at baseline (HR, 0.06; 95% confidence interval [CI], 0.00-0.75; P = 0.03) and peeling of the ILM (HR, 0.05; 95% CI, 0.01-0.39; P = 0.004) were protective factors, while ellipsoid zone disruption (HR, 10.5; 95% CI, 1.04-105; P = 0.05) was associated with an increased risk of FTMH. CONCLUSION Observed eyes with LMH experienced, on average, progressive VA loss. Patients with LMH and altered vision may benefit from surgery. Internal limiting membrane peeling, with perihole ILM sparing, represents a crucial step of the surgery associated with a greater VA and a lower risk of postoperative FTMH.

Incidence and Outcomes of Eye Trauma Associated with Recreative Use of Non-Powder Toy-Guns: a 12-years retrospective study. Am J Ophthalmol 2024:S0002-9394(24)00061-8. [PMID: 38373584 DOI: 10.1016/j.ajo.2024.02.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 02/01/2024] [Accepted: 02/07/2024] [Indexed: 02/21/2024]
Abstract
PURPOSE Non-powder toy-guns (NPTG) are responsible for many ocular traumas. This study aims to detail the outcomes of these injuries, depending on the causative NPTG. DESIGN Retrospective observational case series. METHODS Cases of NPTG-associated ocular trauma managed in a Parisian eye emergency department between August 1, 2010, and January 1, 2023, were reviewed. The date of trauma, causative NPTG, patient demographics, initial and follow-up eye examinations, any surgical procedure, and visual outcomes for each ocular trauma were analyzed RESULTS: Over 12 years, NPTG were responsible for 324 eye injuries and 980 visits. Patients were mostly males (77.5%), and mean age at trauma was 16.2 years. Foam bullets or foam darts blasters accounted for 54.9% of traumas and were mainly responsible for corneal injuries and hyphema (30.9% and 27%, respectively). BB-gun/airsoft guns were frequently responsible for anterior segment lesions, as well as intravitreal hemorrhages (14.7%) and commotio retinae (21.1%). Paintball guns accounted for the largest proportion of posterior segment lesions (such as intra- or subretinal hemorrhages leading to macular atrophy/contusion maculopathy), and one-third of casualties had undergone ocular surgery. Among all traumas, final visual acuity was lower than 20/200 in 6.5% of cases. Phthisis occurred in 8 cases: 2 were related to foam bullets or foam darts blaster injuries (1 contusion and 1 rupture), 2 other cases followed a rupture due to BB-guns/airsoft-guns, 1 case occurred after a rupture related to a paintball gunshot, and 3 others were due to other types of compressed air guns (1 rupture, 1 intraocular foreign body and 1 total retinal detachment). CONCLUSION NPTG-related ocular trauma outcomes differ according to the causative toy. Paintball guns and BB-guns/airsoft guns-related traumas were more likely to be associated with severe lesions, but an increasing number of ocular injuries related to the use of foam bullets or foam darts blasters are reported, in younger and younger children. Public health policies should promote the use of protective eyewear.

Phenomenology of spontaneous closure in degenerative and mixed type lamellar macular hole. Eye (Lond) 2024; 38:315-320. [PMID: 37524832 PMCID: PMC10810871 DOI: 10.1038/s41433-023-02681-y] [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: 12/16/2022] [Revised: 07/04/2023] [Accepted: 07/19/2023] [Indexed: 08/02/2023] Open
Abstract
PURPOSE To the describe OCT imaging characteristics of a cohort of patients showing spontaneously closing degenerative or mixed type lamellar macular holes (LMH) and to compare them to the ones of a sex and age matched group showing stable lesions. METHODS Patients diagnosed with degenerative and mixed type LMHs showing OCT-documented spontaneous anatomical closure were retrospectively selected from 3 specialized retina centres. An equal number of age and sex matching subjects were randomly selected among patients with anatomically stable lesions. RESULTS Eleven (11) spontaneously closing (SC group) and 11 stable (ST group) degenerative LMH with a mean follow up of 4 years were recruited. Hyperreflective inner border (HIB) and linear hyperreflectivity in the outer plexiform layer (LHOP) at baseline were significantly more prevalent in SC group in processed images (respectively p = 0.007 and p = 0.003). A borderline significance in lamellar hole associated epiretinal proliferation (LHEP) at last follow up was detected (p = 0.085). As for mixed type LMH, 10 patients for SC group and 10 for ST group were recruited. LHOP at baseline in processed images was significantly more prevalent in SC group (p = 0.005). CONCLUSIONS Spontaneously closing LMHs show higher prevalence of HIB and LHOP at the beginning of the closing process, a difference which is enhanced by image processing. These signs might be a signal of microglial and Muller cells coordinated activation.

Outcomes of Modified Limbal Lensectomy-Vitrectomy in Stages 4B and 5 Retinopathy of Prematurity with Extended Retrolental Fibroplasia. Ophthalmol Retina 2024:S2468-6530(24)00009-5. [PMID: 38199456 DOI: 10.1016/j.oret.2024.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 01/04/2024] [Accepted: 01/04/2024] [Indexed: 01/12/2024]
Abstract
PURPOSE To report on the anatomical and functional outcomes of a modified limbal lensectomy-vitrectomy (LV) approach for stages 4B and 5 retinopathy of prematurity (ROP) as defined in the International Classification of Retinopathy of Prematurity, 3rd Edition (ICROP 3). DESIGN Retrospective, monocentric, consecutive case series. PATIENTS Infants with ROP that underwent limbal LV for diffuse retrolental fibroplasia. METHODS Clinical charts and Retcam photographs were reviewed. Surgical approach consisted of a limbal LV through peripheral iridectomies with centripetal dissection of the preretinal fibrosis. MAIN OUTCOME MEASURES Anatomical success and visual function at last follow-up were evaluated. Multivariate logistic regression was used to explore potential prognostic factors affecting the anatomical outcome. RESULTS A total of 128 eyes of 81 patients with a mean gestational age of 28.7 ± 3.0 weeks and a mean birthweight of 1244 ± 429 g were included. Eighteen eyes (14.1%) had a stage 4B, 24 (18.8%) a stage 5B, and 86 a stage 5C (67.2%) ROP. Mean age at surgery was 57.4 ± 36.3 weeks and mean postoperative follow-up was 22.7 ± 20.4 months. Only 5 eyes (3.9%) had prior peripheral retinal ablation. Macular reattachment was achieved in 74 eyes (57.8%). Controlling for other baseline factors, a stage 5C (versus stage 4B, odds ratio [OR] = 6.9 [1.5-32.1], P = 0.01 and versus stage 5B, OR = 7.4 [1.5-37.1], P = 0.02), the presence of vascular activity (OR = 6.4 [2.3-18.1], P < 0.001), and the presence of Schlieren sign (OR = 13.0 [2.1-82.2], P = 0.006) were associated with a failure of macular reattachment. Visual acuity was assessed in 92 eyes (71.9%), among which 59 eyes (64.1%) had light perception or better. CONCLUSIONS Modified limbal LV resulted in macular reattachment in more than half of eyes with ROP-related retinal detachment and diffuse retrolental fibrosis. A stage 5C based on ICROP 3, the presence of vascular activity, and a Schlieren sign were significantly associated with a failure of macular reattachment.

Abstract
AIM Preterm children are highly vulnerable to sensorial impairments through Retinopathy Of Prematurity (ROP). The objective was to determine whether some cases of ROP requiring surgery could be secondary to deficiencies in care pathways. METHODS Descriptive study of neonatal characteristics and the screening/treatment pathways of children treated for stage ≥4A ROP from 2009 to 2020 in a referral unit in France. RESULTS Twenty-five preterm children (44 eyes) were included: median gestational age was 25 weeks, and median birthweight was 700 grams. Eighty-four per cent had received at least one fundus examination, 50% of which were completed on time. At the time of retinal detachment diagnosis, only 36% of the children had received laser or anti-vascular endothelial growth factor (VEGF) intra-vitreal injection. ROP stage was only reported in 8%, and the zone or type was reported in 16% of the files. CONCLUSION The risk of blindness and the effectiveness of laser or anti-VEGF treatment highlight the need to enhance screening and treatment practices in France.

Abstract
PURPOSE To describe a new surgical technique and outcomes of lens-sparing vitrectomy and retrolental stalk dissection in posterior persistent fetal vasculature (PFV). DESIGN Retrospective interventional case series. METHODS RESULTS: Among the 21 included eyes, 8 (38%) had no macular involvement and 4 (19%) presented with microphthalmia. Median age at the first surgery was 8 months (range: 1-113 months). Surgical success was obtained in 71.4% of cases (15 of 21). In the remaining cases, the lens was removed because of capsular rupture in 2 cases (9.5%) and a large capsular opacity after stalk removal or an adherent stalk impossible to dissect in 4 cases (19.1%). In the capsular bag, IOL implantation was accomplished for all but 1 eye. None of the eyes developed retinal detachment or required glaucoma surgery. Endophthalmitis occurred in 1 eye. Secondary lens aspiration was needed in 3 eyes after a mean interval of 10.7 months following initial surgery. At last follow-up, half of the eyes remained phakic. CONCLUSION Lens-sparing vitrectomy is a useful approach to addressing the retrolental stalk in selected cases of persistent fetal vasculature syndrome. By delaying or avoiding lens extraction, this approach allows preservation of accommodation, reduction of the risk of aphakia, glaucoma, and development of secondary lens reproliferation.

Abstract
BACKGROUND During the first wave of the coronavirus disease-2019 (COVID-19) pandemic, it was necessary to prepare for the possibility of triaging patients who could benefit from access to an intensive care unit (ICU). In our neuroscience institution, the challenge was to continue to manage usual neurological emergencies as well as the influx of COVID-19 patients. METHODS We report the experience of an ethical consulting unit to support care clinical decisions during the first wave of the pandemic (March 16 to April 30, 2020). Three objective evaluation criteria were defined: 2 of these criteria, patient's factors and general disease severity (Simplified Acute Physiology Score II), were common to all patients, and the third was the specific severity of the disease (neurological for brain injury, respiratory for COVID-19). Given our scarce resources, we used a high probability of a 3-month modified Rankin Scale ≤3 as the criterion for further resuscitation and management. RESULTS A total of 295 patients were admitted during the first pandemic wave; 111 with COVID-19 and 184 with neurological emergencies. The ethical unit's expertise was sought for 75 clinical situations in 56 patients (35 COVID-19 and 21 neurological). Decisions were as follows: 11% no limitation on care, 5% expectant care with reassessment (maximum therapy to assess possible progress pending decision), 67% partial limitation (no intensification of care or no transfer to ICU), and 17% limitation of curative care. At no time did a lack of availability of ICU beds require the ethical unit to advise against admission to the ICU. CONCLUSIONS Our ethical consulting unit allowed for collegial ethical decision-making in line with international recommendations. This model could be easily transferred to other triage situations, provided it is adapted to the local context.

Abstract
INTRODUCTION Epidemiological data on the use of eye-related emergency services by children are limited. The objective of this study was to determine how COVID-19 affected the epidemiological trends of pediatric ocular emergencies. METHODS We performed a retrospective chart review of children under the age of 18 years who visited our eye-related emergency department between March 17 and June 7, 2020 and between March 18 and June 9, 2019. This was a descriptive and comparative analysis of the two study periods based on the demographic characteristics of patients and the diagnosis reported by the ophthalmologist in the digital medical charts. One of the investigators performed a second reading of the files to homogenize the diagnosis classification based on the most frequently found items. RESULTS In total, 754 children were seen in our eye-related emergency department during the 2020 study period versus 1399 in 2019, representing a 46% decrease. In 2019, the four main diagnoses were traumatic injury (30%), allergic conjunctivitis (15%), infectious conjunctivitis (12%), and chalazion/blepharitis (12%). In the 2020 study period there was a significant decrease in the proportion of patients presenting with traumatic injuries (p < 0.001), infectious conjunctivitis (p = 0.03), and chalazion/blepharitis (p < 0.001). Consultations for chalazion/blepharitis were the most affected by the pandemic, followed by traumatic injuries (-72% and -64%, respectively). The proportion of patients who required surgery after trauma was higher in 2020 than in 2019 (p < 0.01), but the absolute number of severe trauma cases remained stable. CONCLUSIONS The COVID-19 pandemic was accompanied by a decrease in the overall use of a pediatric eye-related emergency services in Paris. Visits due to benign causes and ocular trauma also decreased, but visits for more severe pathologies were not affected. Longer-term epidemiological studies may confirm or refute a change in eye emergency department use habits.

Abstract
PURPOSE To describe the 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 at diagnosis: age, gender, presenting symptoms, intraocular pressure (IOP), visual acuity (VA). Patients were divided in four group depending on severity and involvement or not of the anterior segment. We reported the vitreoretinal surgical techniques used. MAIN OUTCOME MEASURES Anatomical results, ocular hypertension, BCVA, presence of post-operative adverse events and additional surgical interventions were recorded at each follow-up visit. RESULTS A total of 96 patients were included. Median age at diagnosis was 8 months (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. Posterior PFV was associated with anterior involvement in 62 eyes (64%). Forty-one eyes (42.7%) were microphthalmic and were more frequently associated with severe PFV [53% vs. 25%; (p=0.01)]. Surgery was performed in 85 patients (89%). Of them, 69 (81%) were a total success, 5 (6%) were a partial success due to a persistent limited peripheral retinal detachment (RD), and 11 (13%) were a failure due to persistent total RD after surgery. Twenty-four eyes presented post-operative adverse events including ocular hypertension requiring eye drop medication (6.6%), secondary cell proliferation around the IOL (7.7%), intravitreal hemorrhages (6.6%), persistent tractional RD (9.9%). A second surgery was performed in 15 patients (16%). At last follow-up, VA could be measured in logMAR in 43 children (45%), was light perception in 21 eyes (22%), and no light perception or impossible to assess in 32 eyes (33%). CONCLUSIONS In our case-series, most of patients presenting PFV with posterior involvement received complex vitreoretinal surgery. Goals of the surgery varies, and include retinal flattening, reduction of vitreoretinal traction, freeing of the visual axis and aesthetic concerns. We proposed a surgical and medical management algorithm for PFV.

First implication of MIP in bilateral microphthalmia with persistent fetal vasculature. Am J Med Genet A 2023; 191:1373-1377.

Abstract
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.

Abstract
PURPOSE To report on the outcome of surgical submacular choroidal neovascular membrane (CNV) removal in children and to perform a comprehensive review of literature concerning this intervention in children. METHODS In this retrospective, noncomparative, interventional case series, we included 8 eyes of 7 consecutive children with subfoveal choroidal neovascularization treated by pars plana vitrectomy (PPV) and CNV removal. Main outcome measures were visual acuity and complications. RESULTS Mean age at surgery was 8.6 ± 5.2 years (range: 2-16). Two out of 8 eyes were idiopathic. Corrected-distance visual acuity (CDVA) improved from 1.01 ± 0.45logMAR (range:0.3-1.5) at presentation to 0.60 ± 0.37 (range:0-1) at last follow-up (p = 0.03). Mean follow-up was 3.9 ± 3.9 years. Six eyes received at least one intravitreal injection of bevacizumab prior to surgery. Recurrence occurred in one eye with Best's disease.Literature review revealed a total of 42 cases with the most frequent etiologies being Presumed ocular histoplasmosis syndrome (POHS) and idiopathic CNV. Considering all cases together, mean CDVA improved from 1.00 ± 0.37logMAR to 0.52 ± 0.42 (p < 0.01). CNV recurrence occurred in 11 eyes (22.0%), 7 of which had an inflammatory etiology. Other complications included pigment epithelium tear, atrophy and retinal tear. CONCLUSION Surgical removal of CNV is a viable, effective and safe option in children with persistent submacular neovascular membranes.

Abstract
Purpose The study aimed to assess the safety and the non-inferiority of cataract surgery outside an operating room using the Surgicube®, a mobile laminar airflow (LAF) device. Settings This single-center study was conducted at the Rothschild Foundation, Paris, France. Design This is a retrospective cross-sectional study. Methods All patients operated on for cataracts using the Surgicube® between February 2020 and February 2021 were included and controlled by a cohort of patients operated on for cataracts in the traditional theater during the same period. Patients with a postoperative follow-up of less than 1 month were excluded. Data collection was carried out using the patient's medical record. The primary endpoint was the evaluation of the number of endophthalmitis in the two groups. The secondary judgment criteria were the analysis of the various complications and the Logmar visual acuity at 1 month in the two groups. All the patients underwent an OCT retinal examination. Results A total of 923 randomized patients who underwent cataract surgery between 2020 and 2021 have been included in the study. Among them, 448 patients were operated on using the Surgicube, and 475 patients underwent surgery in the traditional operating room using the same lens phacoemulsification technique. There are no significant differences between the two groups (p > 0.05). Conclusion Cataract surgery using the Surgicube® outside a conventional operating room seems non-inferior to conventional scrub.

Abstract
PURPOSE The final refraction after intraocular lens (IOL) implantation remains a challenge in the management of paediatric cataracts. No consensual guidelines exist for the choice of IOL power. The aim of this study was to validate a method of IOL power calculation by evaluating the final refractive error in all patients with IOL implantation operated at our institution. METHODS We retrospectively studied all children under 7 years of age who underwent cataract surgery with IOL implantation at our institution between 2010 and 2015. Intraocular lens (IOL) power was calculated as follows: After B-scan determination of the emmetropic IOL power, a reduction of 40%, 35%, 30%, 25%, 20%, 15%, 10% and 5% was applied to children 0-3, 3-6, 6-12, 12-18, 18-24, 24-30, 30-36, 36-48 months, respectively. The following data were collected: follow-up, age at surgery, uni- or bilaterality, implanted IOL power and final refraction. RESULTS During this period, 81 children (125 eyes) met the inclusion criteria with a median follow-up of 60 months (36-97). The median age at surgery was 6.61 months (0.76-48). We included 52 children with bilateral cataract (96 eyes) and 29 children with unilateral cataract (29 eyes). The mean implanted IOL power was 23.3 ± 4.6 diopters (D). The mean spherical equivalent at last follow-up was 0.07 ± 3.5 D. CONCLUSION Our undercorrection formula for IOL implantation after congenital cataract surgery leads to long-term refractive results globally close to emmetropia.

Abstract
PURPOSE Distinguishing posterior persistent fetal vasculature (PFV) from retinal detachment (RD) may be very challenging clinically and ultrasonographically, as they share common morphological features. However, it is crucial, considering their substantially distinct management and treatment. We aimed to assess the relevance of quantitative colour Doppler flow imaging to distinguish PFV from RD in children. METHODS This retrospective bi-centre study included 66 children (30 females and 36 males, mean age: 244 ± 257 days) with a clinically suspected diagnosis of RD or posterior PFV. All children underwent systematic and standardized conventional ultrasonography and colour Doppler flow imaging under general anaesthesia with a qualitative and quantitative analysis of the retrolental tissue's vascularization. Peak systolic velocity, end-diastolic velocity and resistive index were recorded for analysis. Whenever available, surgical findings were deemed gold standard for diagnosis. A Mann-Whitney U-test was used to compare quantitative colour Doppler flow imaging data. RESULTS Peak systolic velocity and end-diastolic velocity were significantly lower in children with PFV versus RD: 2.7 (IQR: 0.5) versus 5.1 (IQR: 2.8), p < 0.001, and 0.0 (IQR: 0.0) versus 2.0 (IQR: 1.2), p < 0.001, respectively. Resistive index was significantly higher in children with PFV versus RD: 1 (IQR: 0) versus 0.6 (IQR: 0.1), p < 0.001. Area under curves (AUCs) were of 0.94, 0.99 and 1, respectively. No differences between PFV and RD were observed on structural ultrasound or qualitative analysis of colour Doppler. CONCLUSION Quantitative colour Doppler flow imaging has an excellent accuracy in distinguishing PFV from RD in children. It may help to improve management and treatment.

Abstract
PURPOSE To evaluate the current French screening guidelines for retinopathy of prematurity (ROP) and to suggest modifications to it. METHODS In this multicentric retrospective, noncomparative, interventional case series we included infants with a gestational age (GA) ≤32 weeks who were screened for ROP by fundus examination between 2011 and 2018. Main Outcome Measures were the presence of ROP and the need for treatment. RESULTS A total of 2246 children with a mean GA of 28.9 ± 2.0 weeks and mean birth weight (BW) of 1141.1 ± 332.0 g were screened. Retinopathy of prematurity (ROP) was found in 683 infants (30.4%), of whom 145 (6.5%) had type 2 ROP and 58 (2.6%) had type 1 ROP. Mean GA of infants with type 1 ROP needing treatment was 25.9 + 1.5 weeks (range: 23.6-30) and mean BW was 774.1 ± 173.7 g (range: 540-1400). Both GA and BW had an impact on the development of type 1 and 2 ROP. None of the infants needing treatment had a GA of 31 weeks or more. None of the children needed treatment before 33 weeks of postmenstrual age (PMA) or 6 weeks of postnatal age (PNA). CONCLUSION It seems possible to decrease the screening of premature infants to ≤31 weeks of GA and to start screening at 31 weeks PMA for infants having a GA < 26 weeks and at 6 weeks PNA for more mature children.

Abstract
PURPOSE To determine the incidence and risk factors for glaucoma after pediatric cataract surgery with intraocular lens (IOL) implantation. DESIGN Retrospective, consecutive case series. METHODS In this single-center study, we reviewed 136 children (199 eyes) who underwent pediatric cataract surgery before 1 year of age with a minimum of 1 year of follow-up. The intervention used was pediatric cataract surgery with IOL implantation, and the primary outcome measure was the presence or absence of secondary glaucoma. RESULTS The mean age at surgery was 148 ± 93 days (range 30-359 days) with a mean follow-up of 6.3 ± 3.6 years (range 1.1-12.8 years). Glaucoma developed in 31 eyes (16%) with 5- and 10-year incidence rates of 12% and 28%, respectively. The incidence of glaucoma seemed to be bimodal, with a first peak occurring after a mean delay of 2.5 months (range 1.6-4.1 months) and a second peak occurring after a mean delay of 5.7 years (range 2.6-11.7 years). Younger age at surgery, shorter axial length, longer follow-up, use of trypan blue, reintervention, and bilateral surgery were associatied with a higher incidence of glaucoma. Multivariate analysis including the aforementioned variables indentified longer follow-up (odds ratio [OR] = 1.3 [95% confidence interval {CI} 1.1-1.6], P = .001), reintervention (OR = 4.1 [95% CI 1.2-13.4], P = 0.02), and the use of trypan blue (OR = 4.1 [95% CI 1.3-13.1], P = .02) as predictors for the development of glaucoma. CONCLUSION Glaucoma is a common complication after pediatric cataract surgery. It seemed to have a bimodal incidence. Risk factors for glaucoma development were reintervention, the use of trypan blue, and a long follow-up.

Abstract
INTRODUCTION Retinopathy of prematurity (ROP) is a blinding disease that requires screening by retinal examination. Screening practices are rarely evaluated. We aimed to determine the prevalence of ROP screening in very preterm infants and individual- and center-related factors associated with ROP screening. METHODS Data were extracted from the EPIPAGE-2 cohort, a French prospective population-based study of premature births in 2011. Children born before 32 weeks' gestation (WG) without severe malformation and alive at the recommended time for ROP screening were included. Outcome measures were achievement of ROP screening and compliance with recommended screening timeline. Individual- and center-related factors associated with both measures were studied using mixed models. RESULTS Among 3,077 eligible infants, 2,169 (70.5%) had a ROP screening, ranging from 96% at 24 WG to 50% at 31 WG. Large variability among units was observed. Individual characteristics associated with screening were low gestational age, low birth weight, severe bronchopulmonary dysplasia or neurological lesions, and transfer between neonatal units during the screening period. Odds of screening were higher in neonatal units using wide-angle imaging (odds ratio 2.65 [95% confidence interval 1.17-6.01]) but decreased in units without a local protocol for ROP screening (0.03 [0.01-0.09]). Among screened children, 1,641/2,169 (75.7%) were screened according to recommended timeline. Delayed screening was associated with low gestational age, severe bronchopulmonary dysplasia or necrotizing enterocolitis, and absence of local protocol for ROP screening. DISCUSSION/CONCLUSIONS In this large cohort study of infants born very preterm, almost one-third were not screened for ROP. Children most at risk for ROP were the best screened but often with delay. The higher compliance of neonatal units using wide-angle imaging systems supports its use.

Abstract
A 2-year-old girl with a 1-year history of photophobia presented with bilateral eye redness and was found to have dendriform corneal ulcers, which were initially managed with acyclovir ointment, without improvement. Clinical inspection revealed small cutaneous lesions on the fingers and toes. The association of pseudodendritic keratitis with palmo-plantar hyperkeratotic lesions was suspicious for tyrosinemia type 2, which was confirmed by high levels of plasmatic tyrosine (2134 μmol/L). A protein-restricted diet led to the complete resolution of the corneal and cutaneous lesions and avoided the potential toxicity of tyrosine on central nervous system.

AIM We evaluated the weight, insulin-like growth factor-1, neonatal, retinopathy of prematurity (WINROP) algorithm for very premature infants. METHOD Infants born before 32 weeks who had undergone fundus examinations in the neonatal intensive care unit at the University Hospital of Nancy were included in this French retrospective cohort study from July 2012 to July 2016. We evaluated how well the WINROP software predicted threshold retinopathy of prematurity (ROP). RESULTS We studied 570 infants with a mean gestational age of 28.7 ± 1.8 weeks and a mean birth weight of 1110 ± 297 g: 28.1% had ROP and 1.2% had threshold ROP. The overall WINROP sensitivity was 57.1%, specificity was 46.0%, predictive positive value was 1.3% and predictive negative value was 98.9%. At more than 30 weeks of gestation or 1250 g, these figures rose to a respective specificity of 100% and 95.7% and respective predictive negative value of 100% and 100%. There were independent associations between the severity of ROP and the Apgar score at five minutes, the duration of oxygen therapy and non-invasive ventilation. CONCLUSION WINROP worked better on preterm infants born from 31 weeks onwards or weighing over 1250 g. Fundus examinations remain necessary for infants born earlier or lighter.

Effectiveness and efficiency of tele-expertise for improving access to retinopathy screening among 351 neonates in a secondary care center: An observational, controlled before-after study. PLoS One 2018; 13:e0206375.

Abstract
In France, secondary care hospitals encounter difficulties to adhere to retinopathy of prematurity (ROP) screening guidelines. Our objective was to assess the effectiveness and efficacy of a tele-expertise program for ROP screening in neonatal intensive care units without on-site ophthalmologists. We evaluated the impact of a tele-expertise program funded by the Paris Region Health Authority in a secondary care center general hospital of the Paris Region (CHSF), where there was previously no on-site ophthalmologist. We performed an observational, controlled before-after study, with a university tertiary care center with on-site ophthalmologists (Port-Royal) as the control group. Recruitment and data collection for both periods took place from 1 January 2012 to 31 December 31 2012, and from 1 January 2014 to 31 March 2015. The primary endpoint was the percentage of compliance with screening guidelines, secondary endpoints included pain scores and costs. Over the two periods, at total of 351 infants were recruited in the CHSF. Implementation of the tele-expertise resulted in an absolute +57.3% increase in the proportion of examinations realized in accordance with guidelines (3.8% during the "before" period and 61.1% during the "after" period, p<0.001). As compared with the control group, the proportion of infants appropriately screened improved (57.5% versus 43.1%, p = 0.002); median pain score on the acute pain rating scale for neonates during examination was significantly higher (median score 5.5/10, range [2.5-5.7] versus 2.0/10, range [1.0-3.1], p = 0.002). Screening rates in the control group remained unchanged. The average cost per examination increased from €337 in the "before" period to €353 in the "after period" in the tele-expertise group. The implementation of tele-expertise for ROP screening in the CHSF medical center resulted in a major improvement of access to care with a small cost increase. The issue of pain control during examination with tele-expertise should be further addressed.

Abstract
Suprachoroidal hemorrhages, both expulsive and delayed non-expulsive, are among the most devastating complications of intraocular surgery. We reviewed the charts of 13 patients with a delayed non-expulsive suprachoroidal hemorrhage (DNSCH) after cataract extraction (3 patients), glaucoma filtering surgery (6 patients), penetrating keratoplasty (3 patients), or vitrectomy (1 patient). All had large hemorrhagic choroidal detachments with nine eyes presenting kissing choroidal detachment, five eyes with associated retinal detachment, and one eye with intravitreous hemorrhage. All patients were treated with systemic corticosteroids before surgery. Eleven eyes underwent anterior drainage sclerotomy, followed by SF6 gas injection in eight eyes, and pars plana vitrectomy with silicon oil tamponade in three eyes. Mean follow-up was 22 months. These procedures gave good anatomical results in eleven cases and good visual results in nine. The results suggest that not all DNSCH need to be drained surgically but that, when surgical drainage is indicated, the use of gas to maintain internal tamponade appears to be beneficial.

Abstract
Lanthanide-activated SrF2 nanoparticles with a multishell architecture were investigated as optical thermometers in the biological windows. A ratiometric approach based on the relative changes in the intensities of different lanthanide (Nd3+ and Yb3+) NIR emissions was applied to investigate the thermometric properties of the nanoparticles. It was found that an appropriate doping with Er3+ ions can increase the thermometric properties of the Nd3+-Yb3+ coupled systems. In addition, a core containing Yb3+ and Tm3+ can generate light in the visible and UV regions upon near-infrared (NIR) laser excitation at 980 nm. The multishell structure combined with the rational choice of dopants proves to be particularly important to control and enhance the performance of nanoparticles as NIR nanothermometers.

Abstract
Purpose Vitreoretinal dysplasia is characterized by a congenital bilateral nonattachment of the retina. In some cases, anteroposition of the iris and lens can lead to corneolenticular contact and corneal opacity, masquerading as Peters’ anomaly. We report 3 cases of vitreoretinal dysplasia initially diagnosed as Peters’ anomaly. Methods Case report. Results Case 1: In a 3-year-old boy with bilateral corneal opacities, high frequency ultrasound showed iridolenticular adherences as in Peters’ anomaly, but color Doppler imaging of the posterior pole revealed a bilateral total retinal detachment. Case 2: In an 18-month-old boy with bilateral corneal opacity and dense cataract, ultrasound revealed a shallow anterior chamber and bilateral vitreous hemorrhage with retinal detachment. Case 3: In a 6-month-old girl with bilateral central corneal opacity, shallow anterior chamber, iridocorneal synechiae, and a cataract, ultrasound revealed a total retinal detachment in the right eye, and was uncertain in the left eye. Corneal transplantation was attempted in the left eye, but a retinal detachment was discovered peroperatively There were associated central nervous system anomalies. Conclusions Vitreoretinal dysplasia is a potentially evolving disease and can lead to anterior chamber thinning, corneal opacity, and secondary glaucoma. Anterior and posterior segment ultrasound is essential to fix the correct diagnosis and prognosis.

Abstract
PURPOSE To evaluate the evolution of chronic uveitis in children undergoing cataract surgery with primary intraocular lens (IOL) implantation. METHODS Twelve children with chronic uveitis underwent cataract surgery with primary posterior chamber intraocular lens (IOL) implantation. RESULTS Fourteen eyes were implanted with a foldable hydrophobic acrylic IOL. The mean follow-up was 35.39 months (8.72-69.57). The mean BCDVA before surgery and at the end of follow-up was 1.11 (0.40-2.30; SD: 0.57) and 0.48 (0-3; SD: 0.77; p=0.007) respectively. The mean oral corticosteroids dosage after surgery and at the end of follow-up was 0.80 mg/kg/day (SD: 0.37) and 0.17 mg/kg/day (SD: 0.24; p=0.001) respectively. All patients except one were treated with methotrexate. Four patients (5 eyes) were additionally treated with anti-tumor necrosis factor agent. CONCLUSIONS Cataract surgery with primary posterior chamber hydrophobic IOL implantation is possible and leads to a good visual recovery in cases of pediatric chronic uveitis. This surgery requires aggressive anti-inflammatory management with immunosuppressive drugs to control inflammation and reduce the corticosteroids dosage.

Abstract
Exploiting the intrinsic photosensitivity of TiO₂ nanoparticles, we demonstrated how ultraviolet (UV) pulsed laser irradiation of acrylate polymer nanocomposite solutions can separate the initial clusters of these colloidal semiconductor nanorods into clearly distinct units. From the irradiated solutions, optically clear nanocomposite films are obtained which exhibit enhanced optical properties with respect to the nanocomposites obtained without previous UV treatment.

Abstract
The first 2 years of life are essential to visual development. The ophthalmological examination of a baby is different from that of an adult, in terms of both methodology and clinical signs. The specifics of examination at this age require a rigorous history taking as a first step: personal and family medical history, first sign of the disease and its progression. Cycloplegic refraction and fundus exam are both critical regardless of the reason for consultation. In addition, fundus exam must be performed at the first visit in cases of strabismus, nystagmus, or abnormal visual function, in order to rule out underlying retinoblastoma. Gross inspection of the patient can offer much information: malformations, visual behavior, oculomotor abnormalities. Quantification of vision and refraction is age-specific. It cannot be based solely on visual behavior, it cannot be just an approximation, and it often needs to be repeated. Lastly, examination of the anterior and posterior segments may require specialized equipment, special techniques, and may reveal pathology specific to the infant. Throughout the examination, patience and gentleness help greatly to insure a reliable diagnosis.

Transcriptomic analysis of human retinal detachment reveals both inflammatory response and photoreceptor death. PLoS One 2011; 6:e28791.

Abstract
BACKGROUND Retinal detachment often leads to a severe and permanent loss of vision and its therapeutic management remains to this day exclusively surgical. We have used surgical specimens to perform a differential analysis of the transcriptome of human retinal tissues following detachment in order to identify new potential pharmacological targets that could be used in combination with surgery to further improve final outcome. METHODOLOGY/PRINCIPAL FINDINGS Statistical analysis reveals major involvement of the immune response in the disease. Interestingly, using a novel approach relying on coordinated expression, the interindividual variation was monitored to unravel a second crucial aspect of the pathological process: the death of photoreceptor cells. Within the genes identified, the expression of the major histocompatibility complex I gene HLA-C enables diagnosis of the disease, while PKD2L1 and SLCO4A1 -which are both down-regulated- act synergistically to provide an estimate of the duration of the retinal detachment process. Our analysis thus reveals the two complementary cellular and molecular aspects linked to retinal detachment: an immune response and the degeneration of photoreceptor cells. We also reveal that the human specimens have a higher clinical value as compared to artificial models that point to IL6 and oxidative stress, not implicated in the surgical specimens studied here. CONCLUSIONS/SIGNIFICANCE This systematic analysis confirmed the occurrence of both neurodegeneration and inflammation during retinal detachment, and further identifies precisely the modification of expression of the different genes implicated in these two phenomena. Our data henceforth give a new insight into the disease process and provide a rationale for therapeutic strategies aimed at limiting inflammation and photoreceptor damage associated with retinal detachment and, in turn, improving visual prognosis after retinal surgery.

Abstract
Endogenous endophthalmitis is a rare eye disease, affecting vulnerable subjects (such as preterm or older elderly subjects), with reserved visual and sometimes vital prognosis. We present a preterm boy, born at 35 weeks and 2 days gestation, who developed a right eye Pseudomonas aeruginosa endogenous endophthalmitis secondary to a left-foot peripherical catheter-infection-associated bacteremia. He had a first intravenous antibiotic therapy associating third-generation cephalosporin and fluoroquinolone, then Ceftazidime® by intravitreous injection and a subconjunctival injection of betamethasone. Because of the development of vitreoretinal retraction, phacophagia and vitrectomy were performed. We point and discuss the severity of this disease, associated with poor visual and vital prognosis, and the importance of prompt biological diagnosis so that the appropriate intravenous antibiotic therapy is chosen. Treatment is also discussed, especially the interest value of antibiotic intravitreous injection in preterm infants.
