Independent studies, shared evidence.
Twilight measures how a patient adapts to dark—a functional signal that can precede structural change on imaging. Investigator-initiated work is how that signal is tested across care settings, disease states, and care models.
Evoq does not replace the investigator’s scientific control of the protocol. Support is matched to the study and to available company resources.
What these studies ask
- 01
Assess Twilight’s effectiveness in clinical environments and home-use scenarios.
- 02
Document functional visual performance related to dark adaptation across diverse patient populations.
- 03
Assess the clinical and economic value of dark adaptometry in primary eye care practice.
Where Twilight can contribute
These domains are priorities, not an exclusive list. Novel questions that use dark-adaptation endpoints are welcome.
Nyctalopia and measurable dysfunction
Correlate patient-reported night-vision complaints with objective dark-adaptation thresholds and recovery kinetics.
Diabetic retinopathy
Evaluate dark adaptation as an early functional test and as a longitudinal monitor in diabetes and diabetic retinopathy.
Early-stage AMD
Study Twilight in early AMD for monitoring treatment response and disease progression alongside structural imaging.
Occupational night-vision screening
Explore screening and safety protocols for professions that depend on reliable night vision.
Teleophthalmology
Integrate dark-adaptation testing into remote visual-health monitoring and distributed care models.
Retinal drug toxicity
Monitor functional change in patients at risk of retinal toxicity from hydroxychloroquine and related agents.
What Evoq may provide
Depending on the proposed study and available resources, support may include:
- Availability of the Twilight device for the duration of the study
- Remote technical and clinical support
- Data analytics and publication support
Support is not automatic. It is scoped after review of the protocol, timeline, and site capacity.
What we expect from investigators
- Obtain IRB approval and ensure study compliance with applicable regulations.
- Collect data systematically and ensure rigorous protocol adherence.
- Prepare and submit study outcomes for peer-reviewed publication or conference presentation.
