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

Alzheimer'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,

Extremely asymmetric ectasia: Tomographically unilateral keratoconus

Acta Ophthalmologica, Volume 103, Issue 5, Page 530-538, August 2025.
Abstract Purpose To investigate the characteristics of apparently stable forms of tomographically unilateral keratoconus (KC). Methods In this retrospective case–control study, strict unilaterality criteria were applied to select tomographically unilateral cases with ≥3 years of follow‐up.

Inter and intra observer reproducibility of the new Oxford CCD Scheimpflug camera [PDF]

Eye, 1991
Scheimpflug photography is a well recognised technique for obtaining sagittal views of the anterior structures of the human eye in vivo. A new generation of Scheimpflug camera, which uses a CCD (charge coupled device) instead of film, permitting the digitised image achieved to be directly analysed using computerised linear scanning densitometry, is ...

Assessing UVA and Laser‐Induced Crosslinking via Brillouin Microscopy

Journal of Biophotonics, Volume 18, Issue 5, May 2025.
UVA crosslinking is the primary treatment to combat keratoconus. Nevertheless, unwanted side effects and limitations due to nonselective irradiation lead to the investigation of alternative irradiation treatments. This study shows similar changes in the Brillouin frequency shift of corneas crosslinked with UVA irradiation and a NIR femtosecond laser ...

Three-Dimensional Camera Calibration Considering Scheimpflug Condition

Journal of the Visualization Society of Japan, 2003
Presently, a new calibration scheme for the camera under the Scheimpflug condition is proposed, which represents an exact projection from the object through the lens to the inclined image sensors and also handles the distortion by the lens theoretically.
