Ocular changes as potential biomarkers for early diagnosis of Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 21, Issue 8, August 2025.
Abstract Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. AD diagnosis often involves a thorough assessment, including clinical evaluation, cognitive testing, medical history examination, genetic testing, and biomarker analysis. Currently, the invasive nature and high costs of biomarker testing,

Age‐Associated Decline in Autophagy Pathways in the Retinal Pigment Epithelium and Protective Effects of Topical Trehalose in Light‐Induced Outer Retinal Degeneration in Mice

open access: yesAging Cell, Volume 24, Issue 7, July 2025.
Transcriptomic analyses reveal an age‐related decline in autophagy pathways in RPE/choroid. These pathways remain unchanged in early AMD but become bidirectionally dysregulated in later stages, along with increased RPE loss. Pre‐treatment with trehalose eyedrops enhances RPE autophagy flux and prevents light‐induced outer retinal degeneration in mice ...

Signs of Intracranial Hypertension in Chronic Inflammatory Polyradiculoneuropathies—A Cross Sectional Cohort Study

open access: yesEuropean Journal of Neurology, Volume 32, Issue 7, July 2025.
This prospective cross‐sectional study screened 27 patients with inflammatory polyradiculoneuropathy (IPN) for signs of intracranial hypertension (IH) using multimodal ophthalmological assessments (fundoscopy, perimetry, OCT, ultrasonography). Signs of IH were identified in 37% of patients.

Assessment of Optic Nerve Head Drusen Using Enhanced Depth Imaging and Swept Source Optical Coherence Tomography [PDF]

open access: yes, 2014
BACKGROUND: Optic nerve head drusen (ONHD) are calcific deposits buried or at the surface of the optic disc. Although ONHD may be associated with progressive visual field defects, the mechanism of drusen-related field loss is poorly understood.

Optical coherence tomography angiography in nonarteritic anterior ischemic optic neuropathy due to optic nerve head drusen [PDF]

open access: yes, 2020
Optic nerve head drusen (ONHD) are typically benign hyaline and calcified concretions located within the optic nerve. Initially asymptomatic, they can increase slowly in size and number over time, and they can cause mechanical stress at the axons of the ...

Multicolor imaging in optic disc swelling

open access: yesIndian Journal of Ophthalmology, 2017
Differentiating optic disc edema (ODE) from pseudo optic disc edema (PODE) continues to pose a diagnostic dilemma. Current report highlights the role of multicolor imaging (MC) in differentiating ODE from PODE.

Optic Disc Pallor in Parkinson's Disease: A UK Biobank Study

open access: yesMovement Disorders, Volume 40, Issue 6, Page 1123-1133, June 2025.
Abstract Background Recent studies have suggested that retinal changes measured with optical coherence tomography are detectable in early Parkinson's disease (PD), highlighting the potential of ophthalmic biomarkers for diagnosis and monitoring. Objective We set out to investigate the relationship between optic disc pallor measured in fundoscopy images
