INTRODUCTION: In addition to sensorineural hearing loss, Waardenburg Syndrome (WS) may present with variable pigmentation of skin and choroid, which may simulate other life-threating conditions (e.g. melanoma). CASE REPORT: Two siblings ostensibly presented with unilateral choroidal pigmentary abnormalities concerning for choroidal tumour. Serial ophthalmic examination documented no lesion growth (base or height) whilst the apparent syndromic features (i.e. iris hypochromia, profound sensorineural hearing loss, SNHL), family history (autosomal dominant inheritance) and positive genetic testing (pathogenic MITF variant) led to a revised diagnosis of Waardenburg Syndrome type 2A...

INTRODUCTION: Choroideremia (CHM) is an X-linked inherited retinal disease mostly affecting males. However, women with phenotypic and/or genotypic evidence of CHM may develop degenerative visual disability with advancing age. Our objective was to determine the visual impacts of phenotypic and/or genotypic evidence of CHM in women and its associated psychosocial burden and influence on activities of daily living (ADLs). METHODS: We conducted an international cross-sectional survey from April to December 2022 using an e-questionnaire distributed through not-for-profit stakeholder organizations and social media plat-forms...

INTRODUCTION: Familial Exudative Vitreoretinopathy (FEVR) is a heritable retinal vascular disease characterized by incomplete vascularization of the peripheral retina resulting in ischemia. Fifty percent of FEVR cases 10 are due to known pathogenic genetic variants, and disease phenotype can vary greatly. FEVR is a clinical diagnosis, however, genetic testing can play a key role in screening for FEVR in genetically susceptible populations, thus leading to early treatment and improved patient outcomes...

BACKGROUND: The clinical approach to inherited eye diseases has evolved due to advances in genetic testing methods and treatment opportunities. However, no data are available on the current practices of ophthalmologists in countries, such as Turkey, with higher rates of consanguinity and inherited eye diseases. The aim of this study was to evaluate the current practices, knowledge, and needs of ophthalmologists in Turkey regarding inherited eye diseases. METHODS: A 29-item self-administered survey with a branching algorithm was developed through Google Forms...

INTRODUCTION: Congenital Myasthenic Syndromes are a diverse group of conditions with a broad array of genetic underpinnings and phenotypic presentations. Acetylcholine receptor deficiency is one form that usually involves pathogenic variants in the Cholinergic Receptor Nicotinic Epsilon Subunit ( CHRNE ) gene encoding the ɛ-subunit of the acetylcholine receptor. METHODS: We report a case of a 4-year-old male with suspected Congenital Myasthenic Syndrome with Acetylcholine Receptor Deficiency who presented with ocular symptoms and generalized muscle weakness...

PURPOSE: Occult macular dystrophy (OMD) is a cause of visual loss in young adults with a grossly normal fundus appearance. It is considered an autosomal dominant disorder, related to heterozygous pathogenic variants in the gene RP1L1 . The purpose of this study is to report a biallelic form of the disease. RESULTS: A 29-year-old female had undergone neurological workup and ophthalmic examinations for transient visual loss in her left eye over the past two years but there was no definitive diagnosis...

BACKGROUND: GAPO syndrome is a rare autosomal recessive disorder characterized by the acronym of growth retardation, alopecia, pseudo-anodontia and progressive optic atrophy. While the genetic alteration of the ANTXR1 gene has been known for its cause, the full range of its clinical and genetic manifestations is not well explored due to the syndrome's extreme rarity. MATERIALS/METHODS: We report two children born to a non-consanguineous parent in India with classical features of GAPO syndrome...

PURPOSE: To evaluate the corneal endothelial cell morphology in children with autosomal recessive Alport syndrome (ARAS). METHODS: This is a longitudinal, prospective cohort study that evaluated pediatric patients with genetically diagnosed ARAS. Fifty-eight eyes of 29 pediatric patients (12 patients, 17 controls) underwent a full ophthalmic examination. Corneal endothelial cell density (ECD) (cells/mm²), coefficient variation (CV) of cell area (polymegathism), the percentage of hexagonal cells (HEX) (pleomorphism), and central corneal thickness (CCT) were analyzed automatically using a noncontact specular microscopy...

INTRODUCTION: BRPF1 gene on 3p26-p25 encodes a protein involved in epigenetic regulation, through interaction with histone H3 lysine acetyltransferases KAT6A and KAT6B of the MYST family. Heterozygous pathogenic variants in BRPF1 gene are associated with Intellectual Developmental Disorder with Dysmorphic Facies and Ptosis (IDDDFP), characterized by global developmental delay, intellectual disability, language delay, and dysmorphic facial features. The reported ocular involvement includes strabismus, amblyopia, and refraction errors...

BACKGROUND: Juvenile-onset open-angle glaucoma (JOAG) is a rare form of primary open-angle glaucoma (POAG) with an early age of onset before 40 years. Latent transforming growth factor-beta binding protein 2 (LTBP-2) is an extracellular matrix protein with a multi-domain structure and homology to fibrillins. LTBP2 gene variants have been associated with JOAG in a small number of patients. Herein, we report a novel missense variant in the LTBP2 gene in a Turkish family with JOAG...

INTRODUCTION: Patients with the acquired immunodeficiency syndrome (AIDS) have an increased prevalence and incidence of intermediate-stage age-related macular degeneration (AMD). Several elevated plasma inflammatory biomarkers are associated with increased incidence of intermediate-stage AMD in this population. We evaluated the association between AMD risk alleles and plasma inflammatory biomarker levels in persons with AIDS. MATERIALS AND METHODS: Cryopreserved plasma specimens of 229 non-Hispanic White and 252 non-Hispanic blacks from the Longitudinal Study of the Ocular Complications of AIDS cohort were assayed for plasma levels of soluble tumor necrosis factor receptor (sTNFR) 2, interleukin (IL)-18, C × 3motif chemokine ligand 1 (CX3CL1), C-reactive protein (CRP), and soluble CD14 (sCD14)...
