Eye Photography: Types of Imaging and Equipment
UW Health's eye care services (ophthalmology) uses ophthalmic photography to study the eye and diagnose potential problems with vision.
Ophthalmic (or eye) photography is a specialized branch of medical photography that uses specific imaging equipment to photograph, scan or otherwise image the eye.
Types of Eye Imaging
- Optical coherence tomography (OCT)
- Color fundus (retinal) photography (CFP)
- Fluorescein angiography (FA)
- Indocyanine green (ICG) angiography
- Fundus autofluorescence (FAF)
- Corneal topography
- Slit-lamp photography
- External photography
- Optic nerve head analysis
- Endothelial cell-layer photography
Eye Imaging Equipment
- Digital retinal cameras (Topcon and Zeiss): For color fundus photography and fluorescein angiography.
- Optical coherence tomography (OCT Zeiss Stratus, Cirrus): Enables cross-sectional imaging of the retina. Used primarily for macular and optic nerve head imaging.
- Scanning laser ophthalmoscope (HRA2 from Heidelberg Engineering): For fundus autofluorescence, fluorescein angiography and indocyanine green (ICG) angiography.
- Photo slit-lamp micrography: For photographing anterior eye structures such as the cornea, iris, conjunctiva and lens.
- Corneal topography (Orbscan 2): Measures the thickness, refractive power and shape of the cornea
- Optic nerve head analyzer (HRT3, Heidelberg Engineering): For precise optic nerve head imaging. Primarily for patients with, or suspected of having, glaucoma.
- External photography (digital Nikon SLR): For photographing eyelids and other facial structures.
- Rostock corneal module (HRT): For high-magnification of all corneal layers. Enables endothelial cell counts.
