Introduction: Cystinosis is a multisystemic disease manifesting in the eyes initially as asymptomatic corneal cystine crystals and later with photophobia and serious visual impairment. Systemic effects of cystinosis arise from multiple cellular dysfunctions, causing early presymptomatic effects and progressive complications. Corneal crystals are observed across all layers of the cornea from infancy, and crystal accumulation during childhood is rapid.

Uveal melanoma (UM) is the second most common type of primary melanoma in adults, but it is extremely rare in children. We report a 12-year-old boy with a rare juvenile case of UM characterized by specific clinical and genetic features, including eye imaging and cytogenetic analysis. The tumor was analyzed using immunohistochemistry in order to confirm the clinical diagnosis and using next-generation sequencing (NGS) in order to investigate the correlation between pathological features and prognosis.

Pathogenic variants in CNGA1 and CNGB1 genes, respectively, accounting for 1% and 4% of cases, impact the cyclic nucleotide-gated channel in rod photoreceptor cells. The aim of this study was to describe and compare genotypic and clinical characteristics of a cohort of patients with CNGA1- or CNGB1-related RP and to explore potential genotype-phenotype correlations.

Voretigene neparvovec (VN) is the first gene therapy approach approved for their treatment. To date, real life experience has demonstrated functional improvements following VN treatment, which are consistent with the clinical trials outcomes.
View Article and Find Full Text PDFBackground: Non-syndromic inherited retinal dystrophies (IRDs) such as retinitis pigmentosa or Leber congenital amaurosis generally manifest between early childhood and late adolescence, imposing profound long-term impacts as a result of vision impairment or blindness. IRDs are highly heterogeneous, with often overlapping symptoms among different IRDs, and achieving a definite diagnosis is challenging. This narrative review provides a clinical overview of the non-syndromic generalized photoreceptor dystrophies, particularly retinitis pigmentosa and Leber congenital amaurosis.

CTNNB1 is highly expressed in brain as well as in other tissues, including heart. Heterozygous CTNNB1 pathogenic variations are associated with a neurodevelopmental disorder characterized by spastic diplegia and visual defects (NEDSDV) [OMIM #615075], featuring psychomotor delay, intellectual disability, behavioral disturbances, movement disorders, visual defects and subtle facial and somatic features.

They represent the anatomical structures in which the superficial (SCP) and deep (DCP) capillary plexus are embedded. We quantified flow signal (FS) in these capillary plexuses using Swept Source OCT angiography to identify possible markers for postoperative outcome.

Only a few pathogenic variations in the gene associated with ESCS have been reported to date. Here, we describe the clinical and genetic findings of two unrelated pediatric patients with a novel frameshift homozygous variant in the gene.

Narrative Medicine (NM) reveals the more intimate aspects of the illness experience, providing insights into clinical practice.
Design And Setting: This NM project was conducted in Italy between July and December 2020 and involved five eye clinics specialised in IRDs.
Describing the clinical and genetic features of an ethnically heterogeneous group of (inherited retinal diseases) IRD patients from different underrepresented countries, referring to specialized Italian Hospitals, and expanding the epidemiological spectrum of the IRD in understudied populations. The patients' phenotypes underwent were characterized by exhaustive ophthalmological examinations, including morpho-functional testing. Genetic testing was performed using next-generation sequencing (NGS) and gene sequencing panels targeting a specific set of genes, Sanger sequencing and-when necessary-multiplex ligation-dependent probe amplification (MLPA) to better identify the genotype.

When possible, segregation analysis was performed in order to confirm unsolved cases. Each patient's retinal phenotypic characteristics were determined using focal and full-field ERGs, perimetry, spectral domain optical coherence tomography and fundus autofluorescence.

Purpose: We evaluated a series of fellow eyes (FEs) in patients affected by unilateral idiopathic epiretinal membrane (IERM) with spectral-domain optical coherence tomography (SD-OCT) and OCT angiography (OCT-A) to determine if a previous defect in the inner retina is present before the mechanical damage to the inner limiting membrane (ILM) caused by posterior vitreous detachment.
Methods: In patients with IERM (N = 39), ganglion cell layer (GCL) thickness in FEs was assessed with SD-OCT; in a subgroup (N = 25) the vessel density (VD) at the superficial (SCP) and deep capillary plexus (DCP) was assessed with swept-source OCT-A (SS-OCT-A). These values were then compared with 30 age-matched healthy control eyes (CEs).
