14 Clinical Trials for Various Conditions
The purpose of this study is to assess performance of measurements of anatomical and vascular structures of the eye based on OCT and OCTA scans in normal subjects and eyes with pathology.
Data Collection of OCT and OCTA-based Ocular Measurements
Precision of OCT- and OCTA-based Ocular Measurements
Comparison of OCT and OCTA-based Ocular Measurements to those of Predicate
To Compare the agreement and precision between the Topcon DRI OCT Triton and the 3D OCT-1 Maestro with RDB.
The objective of this study is to collect OCT measurement data on normal healthy eyes.
To determine optimal cut-off value for the TopQ cut-off on the DRI OCT Triton plus
To evaluate the image qualities and segmentation performance of Topcon's DRI OCT Triton devices using two light sources.
Compare the signal to noise ratio of each device at various retinal layers.
The objective of this study is to validate the TopQ cutoff scores, which have been previously determined.
To demonstrate clinical substantial equivalence of DRI OCT-1 as comparable to the commercially available Cirrus
To demonstrate clinical substantial equivalence of iVue as comparable to commercially available RTVue.
The investigators are interested in seeing how people with low vision (decreased visual acuity or restricted visual fields) instill eye drops into their own eyes. The investigators hypothesis is that this population will have more difficulty with self-instillation of drops than a better-seeing population. The investigators aim to explore whatever factors may be involved in preventing this population from getting prescribed eyedrops into their eyes, whether it is more related to visual field or visual acuity.
The purpose of the study is to repeatability, reproducibility and agreement of eye measurements in retina and glaucoma patients.
