# Optic disc drusen

Optic disc drusen are calcified deposits within the optic nerve head. They can mimic swelling but usually represent a benign, longstanding change.

## Presentation and risks

Many people are asymptomatic, and drusen are found incidentally.

- Lumpy, elevated optic discs that may autofluoresce on imaging
- Occasional peripheral visual field defects
- Rare complications such as haemorrhage or choroidal neovascularisation
- Often associated with a family history and small crowded discs

## Diagnosis and management

Imaging helps distinguish drusen from true optic disc swelling.

- Ultrasound, OCT, or fundus autofluorescence to confirm buried drusen
- Regular visual field testing to monitor function
- No specific treatment in most cases, just observation
- Prompt evaluation of any sudden visual changes or new bleeding
