Retinal Architecture in ​\u3cem\u3eRGS9-\u3c/em\u3e and ​\u3cem\u3eR9AP\u3c/em\u3e-Associated Retinal Dysfunction (Bradyopsia) [PDF]

open access: yes, 2015
Purpose To characterize photoreceptor structure and mosaic integrity in subjects with RGS9- and R9AP-associated retinal dysfunction (bradyopsia) and compare to previous observations in other cone dysfunction disorders such as oligocone trichromacy ...

Mutations in phosphodiesterase 6 identified in familial cases of retinitis pigmentosa. [PDF]

open access: yes, 2016
To delineate the genetic determinants associated with retinitis pigmentosa (RP), a hereditary retinal disorder, we recruited four large families manifesting cardinal symptoms of RP. We localized these families to regions on the human genome harboring the

Single‐Cell RNA Sequencing of Retina Reveals Nna1 Upregulation in Myopic Diabetic Retinopathy as a Protective Factor Against Diabetic Damage

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
This study investigates a schematic overview of the mechanistic pathways. The relationship between myopia and DR has long been of clinical interest. In diabetic mice, Nna1 expression is downregulated, whereas in diabetic mice with FDM, Nna1 expression is upregulated–particularly in Müller cells–accompanied by decreased vascular endothelial growth ...

Continuous Suppression of Pathological Retinal and Choroidal Neovascularization in Cynomolgus Monkeys via Noninvasive Ophthalmic Delivery of a Novel Anti‐VEGFA Nanobody and Proprietary Penetratin Analog Formulation

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
Pathological retinal/choroidal neovascularization drives vision loss in DR and AMD. Current anti‐VEGF injections, while effective, require invasive, frequent administration. Pene/LQ015, is developed a novel topical anti‐VEGFA nanobody formulation achieving therapeutic intraocular levels through penetratin analog‐enhanced delivery.

Bioactive Glial-Derived Neurotrophic Factor from a Safe Injectable Collagen–Alginate Composite Gel Rescues Retinal Photoreceptors from Retinal Degeneration in Rabbits

open access: yesMarine Drugs
The management of vision-threatening retinal diseases remains challenging due to the lack of an effective drug delivery system. Encapsulated cell therapy (ECT) offers a promising approach for the continuous delivery of therapeutic agents without the need

Non-invasive electroretinography

open access: yesBiomedicine & Pharmacotherapy, 2006
Electroretinographic (ERG) investigations are conventionally performed by using corneal or conjunctival recording electrodes. Both types have to be placed in contact with the eye, resulting invasive and providing discomfort for the patient. This paper presents a simple technique to detect ERG potentials non-invasively.

The Cone Dysfunction Syndromes [PDF]

open access: yes, 2016
The cone dysfunction syndromes are a heterogeneous group of inherited, predominantly stationary retinal disorders characterised by reduced central vision, and varying degrees of colour vision abnormalities, nystagmus and photophobia.

Eletroretinograma de padrão reverso no diagnóstico e acompanhamento das afecções da via óptica anterior [PDF]

open access: yes, 2011
The pattern electroretinogram is an electrophysiological test that assesses the function of inner retinal layers, particularly the ganglion cells layer of retina, using a reversing checkerboard or grating pattern that produces no change in average ...

Alpinetin Nanoparticles Alleviate Optic Nerve Injury Induced by Acute Glaucoma via LRP1‐PPARγ Mediated Regulation of Microglial Lipid Metabolism

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
Microglial lipid metabolic dysfunction drives neurodegeneration in glaucoma. We found loss of LRP1 causes lipid accumulation and inflammation. We developed alpinetin‐loaded nanoparticles (AlpNPs) that bind LRP1, activate the PPARγ‐LXRα‐ABCA1 pathway to restore lipid homeostasis, promote an anti‐inflammatory phenotype, and protect retinal ganglion cells,
