# What is optic disc photography?

Optic disc photography involves taking detailed images of the optic nerve head to document its appearance over time. It is a traditional but still valuable tool in glaucoma and optic nerve assessment.

## Method

Colour or monochrome photographs are captured using a fundus camera, often with stereo pairs to appreciate disc cupping and rim contour. Consistent framing, focus, and exposure are important for comparisons.

- Provides a permanent visual record of disc size, shape, and vessels
- Stereo viewing enhances depth perception of cup and rim
- Images can be digitised for storage and side-by-side review
- Can be combined with red-free photography to highlight nerve fibre defects

## Clinical Use

Serial disc photographs allow clinicians to detect progressive cupping, notching, or haemorrhages that may indicate worsening glaucoma. They also help document other optic nerve disorders.

- Useful when advanced imaging is unavailable or as an adjunct
- Disc haemorrhages captured on photos are important risk markers
- Comparisons over many years can be particularly revealing
- Interpretation should account for image magnification and viewing conditions
