An introduction to OCT in retinal disease.

Ocular coherence tomography (OCT) has been available to ophthalmologists for many years and has had a significant impact on the diagnosis and treatment of many eye conditions. This fast and non-invasive way to image the eye has had a considerable effect on ophthalmic photography services. OCT can be used to assess the structure of the cornea, iris, anterior chamber, optic nerve and retina. This article focuses upon its use in retinal conditions and explores how the technique is used to aid treatment and diagnosis.
