![]() ![]() Home tonometry offers a potential alternative, particularly attractive since the SARS-CoV-2 pandemic, with the increased need to undertake healthcare appointments remotely. However, obtaining repeated office-based diurnal IOP measurements is costly, inconvenient, and time consuming. To obtain a more complete picture of IOP fluctuation, and more precisely determine therapeutic effect, IOP can be measured throughout the day in the office or patients can be admitted to hospital for repeated GAT. IOP fluctuates, and there is increasing evidence that the magnitude of fluctuation may be an important risk factor for progression. The accepted standard for IOP measurement is Goldmann applanation tonometry (GAT), however GAT must be performed in-person by a trained healthcare professional and therefore using GAT, it is only possible to obtain infrequent IOP measurements. Accurate measurement of IOP is therefore essential for glaucoma risk stratification and for determining therapeutic effect. Raised intraocular pressure (IOP) is the primary modifiable risk factor for the development and progression of glaucoma and current treatments target IOP reduction for visual field preservation. Glaucoma is a leading cause of preventable sight loss and thus a major public health concern. Most participants were receptive to using video calling as a platform for teaching home tonometry. Most patients were able to perform home tonometry successfully when taught remotely, with a success rate similar to previously reported rates for face-to-face teaching using the same device. ![]() All participants were interested in continuing home IOP monitoring. All participants were happy with remote teaching, and none would have preferred training to be conducted face-to-face. 83% (10 of 12) obtained successful diurnal measurements at home. Participants had an average age of 60.1 ± 15.5 years. Questionnaires were used to evaluate perceptions on home tonometry and remote training. Successful participants were asked to take a series of home IOP measurements over 48 h. Following training, participants were asked to measure their own IOP, observed remotely by the optometrist. An optometrist conducted a 30 min live video training session via NearMe with each patient. Participants were provided with a rebound tonometer (Icare HOME) and instructions to attend remote teaching from home. This prospective study involved 12 patients with glaucoma attending an outpatient ophthalmology clinic. This project aims to determine the feasibility of teaching patients to perform self-tonometry remotely using a remote video link. The ICare HOME is a self-tonometer which empowers patients to measure their own IOP and allows a more complete picture of diurnal IOP. Intraocular pressure (IOP) is the primary modifiable risk factor in the progression of glaucoma. ![]()
