Retinal dystrophies simulating geographic atrophy: A diagnostic challenge

open access: yesActa Ophthalmologica, EarlyView.
Abstract Geographic atrophy (GA) is the chronic loss of retinal pigment epithelium, photoreceptors and choriocapillaris, marking the dry late stage of age‐related macular degeneration (AMD). GA prevalence is expected to rise in the upcoming decades. Advanced GA leads to central scotomas, reducing visual acuity and quality of life, potentially resulting

The P2Y12 Receptor Antagonist Ticagrelor Reduces Lysosomal pH and Autofluorescence in Retinal Pigmented Epithelial Cells From the ABCA4-/- Mouse Model of Retinal Degeneration

open access: yesFrontiers in Pharmacology, 2018
The accumulation of partially degraded lipid waste in lysosomal-related organelles may contribute to pathology in many aging diseases. The presence of these lipofuscin granules is particularly evident in the autofluorescent lysosome-associated organelles

Structural and biochemical basis for retinol‐binding protein 4 antagonism by tinlarebant

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Retinol‐binding protein 4 (RBP4) is a member of the lipocalin superfamily that is connected to disease states such as insulin resistance, fatty liver disease and ocular disorders including Stargardt disease. Several retinoid and non‐retinoid antagonists of this protein have been developed for potential clinical use, but none have

Pitfalls in diagnosing and long‐term management of ceroid lipofuscinosis NCL4A in a mixed‐breed dog

open access: yesVeterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract An 8‐year‐old, spayed, female, mixed‐breed dog was presented with a 9‐month history of occasionally stumbling on walks, having difficulty navigating stairs and jumping into the car. A prior computed tomography scan of the head revealed mild leptomeningeal enhancement and suggested meningoencephalitis.

Organoids: Current Applications and Future Directions

open access: yesMedComm, Volume 7, Issue 10, October 2026.
Organoids are three‐dimensional multicellular structures derived from stem cells or primary tissues that recapitulate key structural and functional features of native organs. Advances in stem cell biology, biomaterials, and bioengineering have established organoids as powerful platforms for studying human development and disease mechanisms, drug ...

Generation and characterization of a Stargardt’s disease-specific induced pluripotent stem cell line (LVPEIi008-A) with a homozygous nonsense mutation in exon 44 of ABCA4

open access: yesStem Cell Research
The Stargardt’s Disease, Type 1 (STGD1) is associated with the loss of function mutations in ABCA4. This gene codes for a retina-specific, ATP-binding cassette (ABC) family transporter, involved in the transport of the key visual cycle intermediate, all ...

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

open access: yesClinical 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 ...
