Abstract
This report describes a unique case of a Coats-like presentation of familial exudative vitreoretinopathy in an 11-year-old girl. The patient was originally referred for evaluation of presumed Coats disease and presented with telangiectatic vessels, perivascular exudates, diffuse peripheral exudation, and intraretinal hemorrhages. Clinical and angiographical findings were consistent with familial exudative vitreoretinopathy, while genetic testing identified variants of uncertain significance in two associated genes, LRP5 and ZNF408. In silico analysis predicts the LRP5 variant to be pathogenic. Retinal vasculopathies often have phenotypic overlap, warranting angiographic examination of both eyes and genetic testing to uncover the correct diagnosis and guide proper treatment.

Abstract
A 37-week-old girl underwent ophthalmic examination. Born at 32 weeks, the infant weighed 680 grams and received high-flow nasal cannula for respiratory distress of the newborn. Dilated fundus examination of the right eye revealed an atypical chorioretinal coloboma; the left eye revealed hyperpigmentary changes in the macula. Fluorescein angiography of both eyes showed retinal vascularization to zone II. Genetic testing revealed a heterozygous variant of uncertain significance in the catenin Alpha 1 (CTNNA1) gene. CTNNA1 gene abnormalities have been implicated as causes of familial exudative vitreoretinopathy (FEVR). It is important to recognize possible simultaneous retinopathy of prematurity and FEVR.

Abstract
BACKGROUND/PURPOSE To evaluate clinical outcomes and assess genotype-phenotype correlations in patients with familial exudative vitreoretinopathy (FEVR). METHODS Clinical charts of 40 patients with FEVR were reviewed. FEVR was staged per Pendergast and Trese, and retinal dragging and folds further classified per Yaguchi et al. We performed whole-exome sequencing and compared clinical characteristics between genetic-positive and genetic-negative groups. RESULTS The mean duration of follow-up was 5.4 years (range: 0.33, 15) for genetic-positive and 6.9 (range: 1, 20) for genetic-negative patients. The mean age at diagnosis was 5.6 years (0.25, 27) for genetic-positive and 6.0 (0, 32) for genetic-negative patients. Genetic-positive patients reported 100% full-term births and genetic-negative patients reported 45% full-term births ( P = 0.0012). There were more patients with retinal folds with all major vessels affected (Yaguchi's Group 4) in genetic-positive compared with genetic-negative patients (21.4% vs. 2.6%, P = 0.045). TSPAN12 was the most common (57.1%) genetic mutation in our population of which 50% exhibited asymmetric presentation. CONCLUSION Patients who test positive for a typical FEVR gene mutation reported more term births and had more severe disease by Yaguchi's classification. TSPAN12 was the most common genetic mutation in our population and had highly asymmetrical disease.

Abstract
BACKGROUND Retinopathy of prematurity (ROP) and familial exudative vitreoretinopathy (FEVR) are two distinct pathologies of retinal angiogenesis with overlapping clinical features. METHODS Examination, multimodal imaging, and genetic testing were used to guide diagnosis and treatment. RESULTS We report a combined phenotype of X-linked FEVR and ROP in a 4-month-old girl with mosaic Turner syndrome with ring X chromosome born at 26 weeks gestational age. She was initially diagnosed with atypical ROP with a vitreous band causing a localized traction retinal detachment, inferotemporal to the macula in the right eye, vessels to posterior zone 2 with no clear ridge temporally in the left eye, and fluorescein leakage in both eyes. Due to the suspicion of concurrent FEVR, genetic testing using a vitreoretinopathy panel was performed which revealed a mosaic Turner syndrome associated with 45,X/46,X,r(X), subsequently confirmed by chromosome analysis. The deleted region in the ring X chromosome included the NDP and RS1 genes. The patient was treated with laser photocoagulation of the peripheral avascular retina and sub-Tenon's triamcinolone injection in both eyes, intravitreal injection of bevacizumab in the left eye, and pars plicata vitrectomy in the right eye. CONCLUSIONS In premature neonates with atypical ROP, a clinical suspicion of concurrent FEVR or similar vasculopathy is important and genetic testing may elucidate a genetic etiology, which could influence management and prognosis. Turner syndrome can be connected with co-occurring Mendelian gene disorders, particularly in individuals with mosaicism. The concurrence of FEVR and ROP appears to result in atypical and possibly more severe phenotypes.

Abstract
PurposeRetinopathy of prematurity (ROP) like retinopathy (ROPLR) could occur in full/near-term newborns. The causes and clinical features are still largely elusive. This study focused on the risk factors, clinical and genetic characteristics, treatment and outcome, and prognosis of ROPLR.MethodsA total of 47 consecutive full/near-term newborns during 2016–2017 with ROPLR were included. The clinical and genetic characteristics, treatment and outcome, prognosis, and potential underlying etiology of ROPLR were were analyzed.Results91 eyes of 47 infants were found to have ROPLR. The ROPLR regressed completely in 65.9% and partially in 20.9% of eyes without any interventions. Retinal changes of family exudative vitreoretinopathy (FEVR) were allocated in 12 neonates (group A), perinatal hypoxia-ischemia were categorized in 17 neonates (group B), and the other 18 neonates were categorized in group C. Compared to those in group B/C, infants in group A had significantly more severe retinopathy (stage 4/5, p < 0.001) and more treatments (p < 0.00 risk factor 1).ConclusionsPerinatal hypoxia-ischemia might be a major risk factor for ROPLR, in which spontaneous regression was common. FEVR, confirmed by positive family findings and genetic testing, might be the second risk factor of ROPLR, in which retinopathy is more severe and treatment is needed.
