Fundus photography captures detailed images of the retina, optic nerve, and retinal vessels. It provides a permanent record for diagnosis, patient education, and monitoring over time.
Techniques
Modern cameras offer various modes.
- Standard colour fundus photos through dilated pupils
- Wide-field imaging to document peripheral retina
- Fundus autofluorescence to highlight retinal pigment epithelium changes
- Non-mydriatic cameras for quick screening in primary care or diabetes clinics
Clinical value
Serial images support early detection and treatment.
- Tracking progression of diabetic retinopathy, macular degeneration, or glaucoma
- Telemedicine screening programmes for remote or underserved populations
- Patient-friendly visual explanation of eye conditions
- Objective documentation for research and medico-legal purposes
