Clinical Trial Summary

Worldwide, glaucoma is the most common cause of irreversible blindness. The major risk factor is raised pressure within the eye (intraocular pressure, IOP). IOP is typically measured using Goldman applanation tonometry (GAT). This involves instilling anaesthetic eye drops and using a probe to contact the cornea and obtain a pressure measurement. A major disadvantage of GAT is that only limited numbers of pressure measurements can be obtained, whereas IOP is known to vary throughout the day and in ¾ of people is highest during the night. The result is that clinicians have poor understanding of patient's 24 hour IOPs and the effect that this might have on their glaucoma. This is a serious limitation as the treatment of glaucoma depends on lowering IOP.

Recently a new device has become available, designed specifically for home IOP monitoring. The iCare HOME tonometer is a CE marked commercial device (http://www.icaretonometer.com/products/icare-home-tonometer/) that can be used to gain insight into 24-hour IOP fluctuations. We wish to determine the feasibility of home IOP monitoring using this device. The iCare HOME tonometer depends on the patient performing self-tonometry. Testing one's own IOP may be technically difficult and it is likely that large numbers of patients will struggle with this.
