About this study

Official title: Evaluating Effectiveness of Home Testing Devises for Assisting in Management of Glaucoma Outside a Clinical Setting During a 2 Year Period.

With the advancement in technology we have the opportunity of performing the glaucoma testing at home to monitor the disease. The purpose of this study is evaluating the feasibility and patient acceptance of home testing with head mounted perimetry; detection of progression with head mounted perimetry vs office based perimetry; and monitoring the eye pressure measured by patients at home using a portable tonometer.

Read the detailed description

Standard Automatic Perimetry (SAP) is the gold standard test for evaluation of diseases of the visual pathway like glaucoma. Its main goal is to measure differential light sensitivity at several locations in the field of vision. Several devices have been developed since the advent of the Octopus Perimeter and the Humphrey Field Analyzer (HFA) is now the most commonly used machine for checking the visual field. These devices have a number of disadvantages including being stressful for debilitated, ill, or elderly patients to keep their heads still in the perimeter bowl during the test.

Recently, several methods have been introduced for checking the visual field using laptops or iPads. These modalities bring portability but lack fixation methods, environmental control, hardware standardization, and lack the ability of checking the visual acuity. These deficiencies may limit their wide usage. VisuALL is a Head Mounted perimeter that connects to its application on the cell phone or tablet via Bluetooth. In addition to being a portable perimeter and checking visual acuity, it has the ability of monitoring fixation with an accuracy of 1 degree. The measured visual field will be saved on a cloud space and available to the physician and patient. It has been shown that the more frequent visual tests we perform, the earlier we would be able to detect visual field progression. Currently, the visual field test is performed on patients in an ophthalmology clinic with a technician present during the test. The VisuALL has a demo video to provide education to the patient on the simple and user-friendly process of visual field testing.

Tonometry is the measurement of eye pressure. iCare Home Tonometer measurements have been shown to be highly correlated to Goldmann Tonometer measurements which are performed in the ophthalmic office. Multiple studies have highlighted the shortcomings of relatively infrequent in office tonometry. Recent studies have suggested that peak out of office eye pressures are often higher than in office pressures and the iCare Home Tonometer is one option to assess eye pressure outside of the office.

Home monitoring of glaucoma may present opportunities to reduce the burdens of office visits while increasing the monitoring of the visual field and eye pressure. This study is intended to assess the feasibility and utility of home based perimetry and tonometry in the management of glaucoma.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Standard Automatic Perimetry Humphrey Field AnalyzerDiagnostic test

    Also called SAP HFA

    Standard Automatic Perimetry (SAP) using the Swedish Interactive Threshold Algorithm (SITA) Standard Strategy measures the visual field in an ophthalmic setting.

  • visuALL HDiagnostic test

    visuALL H a new portable perimeter measuring the visual field and acuity in a non ophthalmic setting.

    Optical coherence tomography (OCT) is a computerized picture measuring the thickness of the inner layer of the retina that makes the optic nerve.

Study groups in NCT05325996
Study groupRoleWhat they receive
Moderate GlaucomaExperimentalSubjects between ages 20-80 years with a diagnosis of mild and moderate Open Angle Glaucoma in at least one eye with 20/50 vision or better will be included in this study. All subjects will have the Olleyes Perimeter measure their own visual acuity and field once a week during a 2 year period and iCare home to measure their eye pressure 3 times a day for 7 days every 3 months during a 2 year period. All patient will have their routine glaucoma assessment with the standard 24-2 Automatic Perimetry Humphrey Field Analyzer at baseline and every 6 months during a 2 year period; and Spectralis Optical Coherence Tomography thickness of peripapillary RNFL and macular ganglion cell at baseline and yearly during a 2 year period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Visual Field Mean Deviation with VisuALL

    The visual field measures sensitivity of the retina to light at several locations in the peripheral vision. The difference of mean of these measurements compared to a normal database is presented in negative or positive values called mean deviation.

    Visual field mean deviation (MD) (light measurement in decibels in multiple spots across the central and peripheral retina known as entire visual field) will be captured by VisuALL per eye once a week during a 2 year period at participant's home.

    Measured: 12 minutes each week for 104 weeks

  2. Change in Intraocular Pressure with iCare

    Intraocular pressure, measured in millimeters of mercury (mmHG), will be measured by patients using a device called iCare Home Tonometer, specifically designed for patients to measure their eye pressures at home. They will measure eye pressure of each eye 3 times a day for 7 days every 3 months during a 2 year period at participant's home.

    Measured: 15 minutes daily over 1 week, 8 times for 2 years

    Visual field mean deviation (MD) (light measurement in decibels in multiple spots across the central and peripheral retina known as entire visual field) will be measured in the office by Humphrey perimeter 24-2 SITA standard per 3 times at baseline and then every 6 months during a 2 year period..

    Measured: 2 hours, 5 times for 2 years
