Purpose
We investigated glaucoma patients' complications, subjective symptoms, and side effects of continuous 24-h measurement of intraocular pressure (IOP)-related patterns with a contact lens sensor (CLS). We asked the patients to complete a questionnaire about their subjective symptoms after wearing the CLS.
Materials and methods
This was an observational single-facility study. We analyzed 56 patients (35 men, 21 women) who underwent 24-h continuous measurement of their IOP-related patterns with a Triggerfish® CLS. The four questionnaire items asked whether blurred vision, ocular pain, conjunctival hyperemia, and sleep disorder were present/absent. All questionnaire items were answered subjectively. We examined the relationship between the patients' questionnaire results and their visual acuity and visual field.
Results
The rate of blurred vision was 55%; ocular pain, 30%; conjunctival hyperemia, 14%; sleeping disorder, 29%. Patients with good visual acuity tended to report experiencing blurred vision.
Conclusions
When 24-h continuous measurement of IOP-related patterns with a CLS is considered, clinicians should tell the patient about the possibility of blurred vision, ocular pain, conjunctival hyperemia, and/or sleeping disorder.
