OCT Imaging

Optical coherence tomography (OCT) is the single most important diagnostic tool in modern retina care — providing detailed cross-sectional images of the retina in seconds.

What Is OCT?

Optical coherence tomography (OCT) is a non-invasive imaging technology that uses near-infrared light to produce high-resolution, cross-sectional images of the retina and underlying structures. It is analogous to ultrasound but uses light rather than sound waves, achieving micron-level resolution. OCT is painless, requires no injections or dye, and takes only seconds to acquire.

What OCT Can Show

Macular swelling from diabetic retinopathy, vein occlusion, or other causes
Subretinal fluid in wet AMD or central serous chorioretinopathy
Retinal thinning and atrophy in dry AMD or retinal dystrophies
Epiretinal membranes and macular holes
Drusen in age-related macular degeneration
Vitreoretinal traction
Choroidal thickness and structure

OCT Angiography (OCTA)

OCT angiography maps the retinal and choroidal blood vessels without injected dye. It can detect choroidal neovascularization in AMD and other conditions, and is increasingly used alongside or in place of traditional fluorescein angiography for many indications.

Role in Treatment Monitoring

OCT is essential for monitoring treatment response. Changes in retinal fluid, thickness, or structure seen on serial OCT scans guide decisions about injection frequency, laser treatment, and long-term management of chronic retinal conditions.

At every visit: OCT imaging is performed at most retina visits to provide an objective measure of retinal health and guide individualized treatment decisions.
