Retinal imaging & OCT
Retinal imaging & OCT
Optical coherence tomography produces a cross-section of the retina at microscopic resolution, showing layers that no view through a lens can reveal. Combined with widefield retinal photography, it is how we catch disease before it affects your sight.
What's Involved
- Widefield retinal photography — A broad, documented image of the retina without the wait for dilation.
- OCT cross-sections — Layer-by-layer measurement of the macula and optic nerve.
- Year-on-year comparison — Scans stored and compared so real change is distinguished from normal variation.
When to Come In
- Diabetes or high blood pressure — Conditions that damage the retina silently.
- Glaucoma risk or suspicion — Nerve fibre thinning shows on OCT years before field loss.
- Any unexplained vision change — Blur, distortion, or a spot that a refraction does not explain.
