A Pilot Study for the Evaluation of the Safety and Performance of a Combined OCT System (Hydra01)
A Prospective,Open Label,Non-randomized,Single-centre,Exploratory,Stratified Pilot Study for the Evaluation of the Safety and Performance of a Combined Coaxial Optical Coherence Tomography (OCT) System,to Image Diseases of the Posterior and Anterior Segment of the Eye
The novel Coaxial Optical Coherence Tomography (OCT) System is designed to visualize both structures of the retina and choroid.
The purpose of this research is the safety and evaluation of a combined coaxial optical coherence tomography (OCT) system, to image diseases of the posterior and anterior segment of the eye.
調査の概要
詳細な説明
Background and Rationale:
Many posterior segment ocular diseases involve the retinal and choroidal vasculature. A new technology to noninvasively and simultaneously visualize vascular pathology is of utmost importance to reduce patient exposure to different diagnosis methods like e.g. fluorescence angiography. The novel Coaxial Optical Coherence Tomography (OCT) System is designed to visualize both structures of the retina and choroid.
Furthermore, it may be used to image other structures of the eye.
Objective(s):
The purpose of this research is the safety and evaluation of a combined coaxial optical coherence tomography (OCT) system, to image diseases of the posterior and anterior segment of the eye. This device may be useful for the early diagnosis and monitoring of a variety of diseases involving the eye, such as Glaucoma, Diabetic Retinopathy or Age-Related Macular Degeneration. Measurements are compared to normal controls.
Measurements and procedures:
After screening, all participants will undergo a scanning procedure on the same day.
Only one eye of each participant will be scanned with the investigational device. For patients, the eye showing the disease will be chosen, for healthy volunteers, the left or right eye will be scanned according to a randomisation list.
The image quality is rated by the investigator and an independent assessor on a VAS (visual analogue scale). A subgroup of each stratum will have a comparative measurement of the choroid thickness against a SS-OCT (swept-source-OCT) device (Topcon) and a retina thickness against the Spectralis data. The subgroup will consist of half planned sample size. The measurement is taken from one eye, ie. every second participant per stratum will be attributed to the thickness measurement subgroup. The endpoint is a true/false criterion on whether the measurement of the retina and choroid thickness was successful. The thickness is measured in μm. The measurement is considered a "success" if the value is no more than +/- 10% off the reference measurement.
