Ocular Telemetry Sensor Well-Tolerated in Patients With Primary Open Angle Glaucoma
A wireless ocular telemetry sensor appears to be well-tolerated in black patients with primary open angle glaucoma (POAG), according to a prospective, observational cohort study involving 20 individuals.
Participants—all of whom were black—reported their ocular discomfort and were examined at baseline. Participants were then fitted with the Sensimed Triggerfish contact lens sensor and kept a record of their activities for 24 hours before returning for a follow-up exam. Exams were repeated after the lens was removed. Among the results:
- All patients were able to keep the lens in for 24 hours.
- At its lowest point, patient-recorded comfort was 7 out of 10.
- Changes were noted in lid/conjunctival erythema, BCVA, refraction, and pachymetry while the lens was worn.
- Most changes returned to normal 1 hour or less after the lens was removed.
- Voltage output was better at night than during the day.
- No signal variability or slope changes were observed during the sleep/wake period based on sleep.
