Introduction

Optical coherence tomography (OCT) has become a successful application in ophthalmology. Time-domain OCT (Stratus, Carl Zeiss Meditec) has been overtaken by spectral-domain OCT (SDOCT) which has major advances in imaging speed, sensitivity and image resolution.1 ,2 Several SDOCT devices are commercially available.

In this small study, we assessed the change in subjective image quality and image quality parameter (IQP) provided by four different SDOCT devices using artificial filters simulating optical eye media disturbances.

Methods

In four healthy subjects, single non-averaged B-scans of the macula were acquired using four commercially available SDOCT systems:

  1. 3D OCT-1000 MarkII (Topcon Medical Systems, Inc, Oakland, New Jersey, USA): Software V.3.21, 27.000 A-scans per second, superluminescent diode 840 nm light source, 5–6 micron axial resolution, ‘Q-factor’ IQP scale 0–100.

  2. Cirrus HD-OCT (Carl Zeiss Meditec, Dublin, California, USA): Software V.2.0, 27.000 A-scans per second, superluminescent diode 840 nm light source, 5 micron axial resolution, ‘Signal Strength’ IQP scale 0–10.

  3. RTVue OCT (Optovue, Inc, Fremont, California, …
