Optical Coherence Tomography (OCT) is the single most important diagnostic tool in modern retinal practice. This guide explains the technology in plain language for practice owners.

What OCT does:

OCT uses low-coherence light to produce cross-sectional images of the retina at micron resolution — non-invasive, fast, and repeatable.

Which systems exist:

- Time-domain OCT (older, slower)
- Spectral-domain OCT (current standard)
- Swept-source OCT (highest speed and penetration)
