Retinal imaging by spectral optical coherence tomography

Eur J Ophthalmol. 2007 Mar-Apr;17(2):238-45. doi: 10.1177/112067210701700214.

Abstract

Purpose: To demonstrate applicability of high speed spectral optical coherence tomography (SOCT) method for imaging retinal pathologies in clinical conditions.

Methods: SOCT was performed in 67 eyes with different macular diseases. Examinations were carried out with the prototype SOCT instrument constructed in the Institute of Physics, Nicolaus Copernicus University, Toruń, Poland. A broadband superluminescent diode was used as a light source.

Results: The disturbances of retinal layer structure concerning mainly outer segments of photoreceptors were observed in case of central serous chorioretinopathy and choroidal neovascularization in age-related macular degeneration. Large drusen were often related to significant changes of outer nuclear layer thickness and reflectivity.

Conclusions: SOCT detects small disturbances of the retinal structure and helps to precisely determine layers involved in different pathologies.
