Recurrent retinal detachment in Stickler Syndrome.

Objective: To assess clinical factors leading to recurrent retinal detachment (RD) and characteristics of recurrence in patients with Stickler Syndrome.

Methods: Retrospective case series study of patients with clinical diagnosis of Stickler Syndrome who underwent rhegmatogenous RD repair. Recurrent RD after initial surgery was categorized as "early" if the recurrence was within 1 year or "late" if greater than 1 year.

Recurrent Retinal Detachment in Stickler Syndrome.

Objective: To assess clinical factors leading to recurrent retinal detachment (RD) and characteristics of recurrence in patients with Stickler Syndrome.

Early diagnosis and treatment by newborn screening (NBS) or family history is associated with improved visual outcomes for long-chain 3-hydroxyacylCoA dehydrogenase deficiency (LCHADD) chorioretinopathy.

Long chain 3-hydroxyacyl-CoA dehydrogenase (LCHADD) is the only fatty acid oxidation disorder to develop a progressive chorioretinopathy resulting in vision loss; newborn screening (NBS) for this disorder began in the United States around 2004. We compared visual outcomes among 40 participants with LCHADD or trifunctional protein deficiency diagnosed symptomatically to those who were diagnosed via NBS or a family history. Participants completed ophthalmologic testing including measures of visual acuity, electroretinograms (ERG), fundal imaging, contrast sensitivity, and visual fields.

A proposal for an updated staging system for LCHADD retinopathy.

Objective: To develop an updated staging system for long-chain 3-hydroxyacyl coenzyme A dehydrogenase deficiency (LCHADD) chorioretinopathy based on contemporary multimodal imaging and electrophysiology.

Methods: We evaluated forty cases of patients with genetically confirmed LCHADD or trifunctional protein deficiency (TFPD) enrolled in a prospective natural history study. Wide-field fundus photographs, fundus autofluorescence (FAF), optical coherence tomography (OCT), and full-field electroretinogram (ffERG) were reviewed and graded for severity.

To describe the anterior segment (AS) findings in patients with microphthalmia with linear skin defects syndrome (MLS), also known as microphthalmia, dermal aplasia, and sclerocornea (MIDAS). A retrospective chart review was conducted to identify patients with a diagnosis of MLS syndrome seen at UPMC Children's Hospital of Pittsburgh. Ophthalmic examination, high-frequency ultrasound, AS optical coherence tomography, and molecular testing were reviewed.

Congenital corneal staphyloma in 8q21.11 microdeletion syndrome.

Background: Although 8q21.11 microdeletion syndrome (8q21.11 DS) has been reported in association with congenital corneal opacities, reports of the clinicopathological features and management are scarce.

ADAMTSL4-related ectopia lentis: A case of pseudodominance with an asymptomatic parent.

Pathogenic variants of ADAMTSL4 are associated with autosomal recessive ectopia lentis et pupillae and isolated ectopia lentis, often presenting congenitally or in childhood. We describe a pedigree of a 4-year-old female child with bilateral ectopia lentis and her asymptomatic 35-year-old father with mild anterior segment findings. Molecular evaluation revealed compound heterozygosity for ADAMTSL4 pathogenic variants in the proband and homozygosity for an ADAMTSL4 pathogenic founder mutation in her father.

Macular atrophy in related Alagille syndrome: a case series.

Background: : Alagille syndrome (AS) is a multisystem disorder associated with a range of ocular anomalies affecting the anterior and posterior segments. While chorioretinal abnormalities have been reported in Alagille Syndrome, identification of macular dystrophy and detailed clinical and electrophysiologic descriptions are scarce.

Materials And Methods: : A retrospective review was conducted to identify patients with a diagnosis of AS and retinal disease who were evaluated in the Division of Pediatric Ophthalmology, Strabismus, and Adult Motility at UPMC Children's Hospital of Pittsburgh.

Somatic KRAS mutation affecting codon 146 in linear sebaceous nevus syndrome.

Linear Sebaceous Nevus Syndrome is a rare disorder that presents with nevus sebaceus in association with corneal dermoids, colobomas, choroidal osteomas, and arachnoid cysts. It is thought to represent a mosaic RASopathy. These are disorders characterized by postzygotic somatic mutation in genes involved in RAS/MAPK signaling pathway.

related Congenital Stationary Night Blindness in Two Siblings due to Probable Maternal Germline Mosaicism.

: Congenital Stationary Night Blindness (CSNB) is a clinically and genetically heterogenous inherited retinal disorder associated with nystagmus, myopia, strabismus, defective dark adaptation, and decreased vision. Pathogenic variants in at least 17 genes have been associated with CSNB, where a hemizygous variant of causing an X-linked form of the disorder is among the commonest causes.: A retrospective chart review of a single pedigree was performed.

Novel clinical presentation of a rod-cone dystrophy.

We describe a novel clinical presentation of a rod-cone dystrophy in a single family. Two boys ages 6 and 12 years presented with clinical and optical coherence tomography features suggestive of X-linked retinoschisis, but with optic nerve swelling without increased intracranial pressure. One patient had an electronegative electroretinogram (ERG) and the other had rod-cone dysfunction.

Keratoconus in a child with partial trisomy 13.

Clinical studies suggest the importance of genetic components in the etiology of keratoconus. However, the contributing genes and variants remain elusive. We present a case of bilateral keratoconus in a child with partial trisomy 13, with a trisomic region spanning loci that have been associated with keratoconus.

Transcriptome from opaque cornea of Fanconi anemia patient uncovers fibrosis and two connected players.

Congenital corneal opacities (CCO) are a group of blinding corneal disorders, where the underlying molecular mechanisms are poorly understood. Phenotyping through specialized imaging and histopathology analysis, together with assessment of key transcriptomic changes (including glycosaminoglycan metabolic enzymes) in cornea(s) with CCO from a case of Fanconi anemia is the approach taken in this study to identify causal mechanisms. Based on our findings, we propose a novel mechanism and two key players contributing to CCO.

Expansion of the ophthalmic phenotype of SPINT2-related syndromic congenital sodium diarrhea.

A 5-year-old girl presented with treatment-refractory dry eye and recurrent episodes of eye pain. She had been previously diagnosed with syndromic congenital sodium diarrhea (SCSD) caused by a pathogenic variant in SPINT2. Her local pediatric ophthalmologist had made the diagnosis of severe dry eye with corneal erosions, based on which, we arranged an eye exam under anesthesia (EUA) and punctal plug placement.

Developing a pediatric ophthalmology telemedicine program in the COVID-19 crisis.

Purpose: To describe our methodology for implementing synchronous telemedicine during the 2019 novel coronavirus (COVID-19) pandemic.

Methods: A retrospective review of outpatient records at a single children's hospital from March 21 to April 10, 2020, was carried out to determine the outcome of already-scheduled face-to-face outpatient appointments. The week leading up to the March 21, all appointments in the study period were categorized as follows: (1) requiring an in-person visit, (2) face-to-face visit that could be postponed, and (3) consultation required but could be virtual.

Syndromic and Systemic Diagnoses Associated With Isolated Sagittal Synostosis.

Unlabelled: Reports of systemic associations in patients with Isolated Sagittal Synostosis (ISS) are sparse. Craniofacial surgeons, and other providers, should be aware that a significant proportion of patients with ISS may have syndromic or systemic involvement. This study investigates the incidence of systemic disease and syndromic diagnosis in a cohort of patients presenting with ISS (ie, patients with sagittal synostosis without other sutural involvement).

Personalized pediatric ophthalmology: a case report.

The availability of genetic sequencing has given physicians a new tool for diagnosis and treatment of disease, and "personalized medicine" has become an increasingly common term in general but not in pediatric ophthalmology. We present a case of a toddler who developed ataxia, opsoclonus, myoclonus, and developmental regression following anesthesia for a common otolaryngology procedure. The child was found to have a variant in the MT-ND6 gene (m.
