Defining Retinal Structures Using Hyperspectral Retinal Imaging

Status: Recruiting

Location: See location...

Intervention Type: Device

Study Type: Interventional

Study Phase: Not Applicable

SUMMARY

This study evaluates hyperspectral retinal imaging as a novel, non-invasive imaging technique to characterise retinal and optic nerve structures in healthy individuals and patients with eye disease. Hyperspectral imaging captures retinal data across multiple wavelengths to generate detailed spectral information that may reveal features not visible with conventional retinal photography. Approximately 1000 participants will undergo multi-modal ophthalmic imaging in Melbourne, Australia, including hyperspectral imaging, OCT, fundus photography, and related tests. The study aims to compare hyperspectral imaging with standard imaging methods and assess its ability to identify retinal biomarkers associated with diseases such as diabetic retinopathy, glaucoma, and age-related macular degeneration.

Treatments

Experimental: Hyperspectral retinal imaging

Participants undergo non-invasive hyperspectral retinal imaging as part of a multi-modal ophthalmic imaging protocol. Hyperspectral imaging is performed using the Optina Diagnostics Metabolic Hyperspectral Retinal Camera and/or a prototype hyperspectral camera developed at the Centre for Eye Research Australia.~The intervention involves sequential retinal imaging across multiple wavelengths (\>25 spectral bands) following standard dilated fundus examination. Imaging is similar to conventional retinal photography but provides additional spectral information for each retinal pixel.~Participants also undergo standard clinical imaging (including OCT, OCT angiography, fundus photography, and autofluorescence) for comparison. The study is observational and non-therapeutic, with hyperspectral imaging used solely for research analysis of retinal structure and spectral biomarkers.
