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 ...

Ordered Chaos: Photoreceptor Mosaics in the Larval and Adult Turquoise Killifish (Nothobranchius furzeri)

Journal of Comparative Neurology, Volume 534, Issue 9, September 2026.
The annual turquoise killifish (Nothobranchius furzeri) cone photoreceptor mosaic is an ordered lattice but lacks regularity of cone subtypes in adulthood. The cone mosaic differs between life stages and has characteristics observed in other fishes adapted for life in turbid water.

The segregation of Calb1, Calb2, and Prph neurons reveals distinct and mixed neuronal populations and projections to hair cells in the inner ear and central nuclei

Developmental Dynamics, Volume 255, Issue 9, Page 845-866, September 2026.
Three populations of hair cells have a distinct expression of Calb1 and Calb2. (A, A′D) The central is highly positive for Calb1 while surrounding HC are positive for Calb2. Later, a calyx forms primarily with Calb1. (B, B′, D′, D″) Saccule and utricle start out positive for Calb2 but will upregulate the Calb1 in the striola that is primarily forming ...

Construction and Validation of a Long‐Term Visual Prognosis Prediction Model for Proliferative Diabetic Retinopathy After Vitrectomy Based on Machine Learning

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 5, September 2026.
This study developed and validated a machine learning‐based prognostic model for predicting long‐term visual outcomes after pars plana vitrectomy (PPV) in patients with proliferative diabetic retinopathy. ABSTRACT Introduction This study aims to develop a machine‐learning‐based risk prediction model for a long‐term visual prognosis in patients with ...
