Photographs of the back of the eye (retina and optic nerve) to document and monitor eye conditions.
Fundus photography takes detailed photographs of the back of your eye, including the retina, optic nerve (optic disc), and blood vessels. These photos help document findings and track changes over time.
Key Takeaways
- Photographs the back of the eye
- Documents optic nerve and retinal appearance
- Useful for comparing changes over time
- Quick, non-invasive procedure
- May require dilated pupils
Why It's Done
- Document optic disc appearance (papilledema, pallor)
- Monitor changes in conditions
- Compare to previous photos
- Share images with other doctors
- Patient education
What to Expect
Before Photography
- Pupils usually dilated
- Wait 20-30 minutes for drops to work
During Photography
- Chin on rest, forehead against bar
- Focus on target inside camera
- Brief bright flashes
- Multiple photos taken
- Takes 5-10 minutes
After Photography
- Vision may be blurry from dilation
- Light sensitivity for few hours
- Bring sunglasses
Types of Fundus Photography
Color Photos
- Standard photos showing natural colors
- Shows hemorrhages, pallor, swelling
Red-Free (Green) Photos
- Highlights blood vessels and hemorrhages
- Nerve fiber layer defects more visible
Autofluorescence
- Special imaging using eye's natural fluorescence
- Useful for detecting optic disc drusen
Wide-Field Photography
- Captures more peripheral retina
- Useful for comprehensive documentation
Comparing to Previous Photos
One of the most valuable uses is comparison:
- Detect subtle changes
- Monitor progression or improvement
- Objective documentation
