Two optical coherence tomography angiography (OCTA) devices, Maestro2 and Cirrus, demonstrated high accuracy in detecting retinal vascular pathologies. Both OCTA devices showed comparable clinical performance, proving effective in identifying and ruling out disease.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Retinal Vascular Diseases

Background:

  • Optical coherence tomography angiography (OCTA) is a key imaging modality for evaluating retinal and choroidal vasculature.
  • Clinical performance of different OCTA devices, particularly semi-automated ones, requires rigorous evaluation against established angiography standards.
  • Fluorescein angiography (FA) and indocyanine green angiography (ICGA) remain crucial reference standards for validating new imaging techniques.

Purpose of the Study:

  • To compare the clinical performance of two OCTA devices: the semi-automated 3D OCT-1 Maestro2 and the Cirrus™ HD-OCT 5000.
  • To assess image quality and pathology detection capabilities of these OCTA devices.
  • To evaluate OCTA performance against FA and ICGA as reference standards for retinal and choroidal pathologies.

Main Methods:

  • Prospective cross-sectional study involving normal eyes and eyes with various retinal/choroidal pathologies.
  • OCTA imaging performed using Maestro2 and Cirrus HD-OCT 5000 devices.
  • Independent grading of OCTA scans and FA/ICGA images for image quality, vascular features, and pathology presence; calculation of positive and negative percent agreement (PPA/NPA).

Main Results:

  • Study included 38 normal eyes and 86 eyes with pathologies.
  • Majority of OCTA images from both devices were deemed clinically useful.
  • High PPA and NPA values were observed for both OCTA devices, indicating strong diagnostic agreement with FA/ICGA.

Conclusions:

  • The semi-automated Maestro2 and Cirrus HD-OCT 5000 exhibit comparable and clinically effective performance.
  • Both devices demonstrate high accuracy in identifying vascular pathologies in the retina and choroid.
  • OCTA technology, as represented by these devices, is reliable for diagnosing various ocular vascular conditions.
