Evaluate the Effects of Long-term Use of Psychotropic Medications on Eye Movement Patterns With the Gaize Device

Sponsored by Gaize

About this study

The study aims to verify if the Gaize ocular device can effectively identify eye movements indicative of prescribed psychotropic medication usage by employing Drug Recognition Expert (DRE) testing protocols within a controlled virtual environment.

The use of psychotropic (psychiatric) medications for various psychiatric disorders is a common practice. Long-term use of such medications necessitates monitoring due to potential side effects, including ophthalmic issues (1). The Gaize VR headset represents a novel approach to monitoring these effects by utilizing Drug Recognition Expert (DRE) testing methods to detect eye movements associated with substance use. Psychotropic medications have been associated with a range of visual and oculomotor side effects, which can impact patient safety and quality of life (2). The prevalence of these effects in long-term users is not fully characterized in the literature, and traditional methods of assessment may miss subclinical alterations in eye movement or function. Eye movement patterns are al…

  • ✕Had your eyes dilated by a medical doctor in the previous 24 hours.
  • ✕Photosensitive epilepsy
  • ✕Diagnosed with clinical blindness
  • ✕Medical Conditions: Participants with medical conditions or medications that could significantly affect cognitive and motor functions are excluded.

  • ✕Current or past head inject/ traumatic brain injury (TBI)
  • ✕Pregnancy: Pregnant individuals will be excluded from the study due to the potential risks associated with psychiatric medications.
  • ✕History of Severe Motion Sickness: Participants with a history of severe motion sickness in VR environments may be excluded, as they may not tolerate the VR headset well.
  • ✕Potential participants who are unable to provide consent for the study.

Only the research team can confirm whether you qualify. The intake questionnaire is the best way to find out.

Completing a questionnaire on Clinably does not enroll you in a clinical trial or confirm your eligibility. Only the research team can determine whether you qualify to participate.
