Sporadic Retinal Astrocytic Hamartoma Mimicking Retinoblastoma in a Child: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Retinal astrocytichamartoma (RAH) is a rare benign glial neoplasm most commonly associated with tuberous sclerosis complex (TSC). Sporadic cases, occurring in the absence of systemic phakomatosis, are uncommon and may closely mimic retinoblastoma, particularly when presenting with a calcified intraocular mass, creating a diagnostic challenge ...

Hippocampal Subfield Volumetry and Navigation in Congenital Blindness

Hippocampus, Volume 36, Issue 5, September 2026.
ABSTRACT The hippocampus is essential for efficient navigation. Although lack of visual experience from birth induces volumetric and structural modifications to the hippocampus, tactile and auditory navigation remain partially preserved in congenitally blind (CB) individuals.

Plasma Lactate Response to a 12‐Min Walk Test Is a Poor Diagnostic Biomarker for Mitochondrial Myopathy

JIMD Reports, Volume 67, Issue 5, September 2026.
ABSTRACT Mitochondrial myopathy (MM) represents a group with a broad phenotypic spectrum which complicates the diagnostic process. This study investigated whether plasma lactate changes following a 12‐min walk test (12MWT) and 20‐min recovery could be a diagnostic screening tool for MM. Thirty patients with MM and 19 healthy controls (HC) participated.

Compound Heterozygous PCDH15 Variants Associated With Cone‐Rod Dystrophy in a Chinese Pedigree

Molecular Genetics &Genomic Medicine, Volume 14, Issue 9, September 2026.
This study represents the first report suggesting a genotype–phenotype relationship between PCDH15 genetic variants and isolated retinal manifestations absent auditory impairment or syndromic features, thereby providing preliminary evidence that may broaden the mutational spectrum associated with this gene.

The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, Volume 104, Issue 6, Page 616-637, September 2026.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Minocycline and bone marrow–derived mononuclear cells as potential therapeutics for hereditary retinal degenerations

Acta Ophthalmologica, Volume 104, Issue 6, Page e671-e685, September 2026.
Abstract Purpose To assess in Royal College of Surgeons (RCS) rats if the combination of two previously documented neuroprotective strategies: minocycline administration and bone marrow–derived mononuclear cells (BM‐MNCs) intravitreal transplantation, offers enhanced neuroprotection compared with each treatment alone.

The mechanistic functional landscape of retinitis pigmentosa: a machine learning-driven approach to therapeutic target discovery

Journal of Translational Medicine
Background Retinitis pigmentosa is the prevailing genetic cause of blindness in developed nations with no effective treatments. In the pursuit of unraveling the intricate dynamics underlying this complex disease, mechanistic models emerge as a tool of ...

Presentation of Complex Homozygous Allele in ABCA4 Gene in a Patient with Retinitis Pigmentosa

Case Reports in Ophthalmological Medicine, 2015
Retinitis pigmentosa is a degenerative retinal disease characterized by progressive photoreceptor damage, which causes loss of peripheral and night vision and the development of tunnel vision and may result in loss of central vision. This study describes
