NCT03079713
Intravitreal injections are an efficient method of delivering therapeutic levels of medications to the posterior segment of the eye. Prior to receiving an injection, there are various methods to provide ocular anesthesia. Vibration may have an anti-nociceptive effect by directly decreasing the sensitivity of peripheral nociceptors or by reducing signal transmission from peripheral nociceptors to the brain with activation of vibratory sensation pathways. The purpose of this study is to evaluate the use of a handheld fingertip vibrator compared to topical eye drops for pain control while performing intravitreal eye injections. A secondary objective of the study is to measure corneal and conjunctiva sensitivity with and without activation of the vibrator to the lower lid using a Luneau Cochet-Bonnet aesthesiometer.
NCT03937310
The purpose of this study is to investigate the role of genetic testing to look for possible infection as a cause for failure of non-healing fractures. The study aims to compare the results of genetic testing known as NGS to standardized clinical laboratory tests for diagnosing infections to see if NGS may be a better diagnostic tool.
