Optical Coherence Tomography
A non-invasive 3D imaging test that uses light waves to take cross-section pictures of your retina, which helps with early detection, diagnosis and treatment guidance for retinal diseases and conditions.
Optical Coherence Tomography (OCT) is a non-invasive eye diagnostic tool that provides an in vivo cross sectional view of the back of the eye, specifically, the retina. OCT allows optometrist to view a cross-sectional map of the retina, which is useful in the diagnosis to detect eye disease related to retina.
In general, OCT can be particularly helpful in diagnosing macular lesions:
- macular hole
- macular pucker ( also called an epiretinal membrane)
- vitreomacular traction
- macular edema
- detachments of the neurosensory retina and retinal pigment epithelium (e.g. central serous retinopathy or age-related macular degeneration)
