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)
  • Image of corneal ulcerColor 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.
