Brief summary
The purpose of this study is to compare glaucoma patients' own I Care measurements by the standard Goldmann applanation tonometer intraocular pressure (IOP) measurements.
Detailed description
not necessary
Interventions
DEVICEHome iCare (study nurse)
the intraocular pressure is measured by iCare performed by the study nurse
DEVICEgoldmann applanation tonometry
the intraocular pressure is measured by goldmann applanation tonometry
DEVICEhome iCare (by patient)
the intraocular pressure is measured by the iCare performed by the patient him self

Inclusion criteria
* Ocular hypertension (OHT):with/without glaucoma drugs * Primary open angle glaucoma (POAG)- high pressure: Diagnosis based on optic nerve head rim loss and/or visual field defects and intraocular pressure (IOP) \>21 mmHg. * Primary open angle glaucoma, normal pressure: cfr high pressure but intraocular pressure ≤ 21 mmHg * Exfoliative Glaucoma (PEX): Diagnosis based on optic nerve head rim loss and/or visual field defects and intraocular pressure (IOP) \>21 mmHg, with exfoliation material in the anterior segment. * Pigmentary Glaucoma (PDG): Diagnosis based on optic nerve head rim loss and/or visual field defects and intraocular pressure (IOP) \>21 mmHg, with Krukenberg's spindle and/or pigment dispersed on the trabecular meshwork.
Exclusion criteria
* Age \<18 years * Other glaucoma types * Corneal pathology (edema, dystrophia, corneal transplantation, severe keratoconus, permanent contact lens wear, recurrent corneal erosion) * Severe arthritis (unable to handle home i care device) * Lack of comprehension * Intra ocular surgery and laser treatment during the last 6 months
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intra-ocular pressure with Home ICare and Goldmann Applanation Tonometer. | immediate comparison, no time frame required | Patients eye pressure measurement with both devices. 1. Home ICare measurement by study nurse compared to Home ICare by patient compared to Goldmann ATO by study nurse (once for every patient) 2. 4 times daily: measurement Goldmann ATO (by resident in ophthalmology) and home Icare (by patient)on same moment |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient Comfort | 1 day hospitalisation | The comfort of the patients will be checked with both methods (home iCare and goldmann applanation tonometry) and look if the patient has a preference for one of them. Pain and discomfort were scaled from 0 to 5 (0 = none,1-2 = slight, 3-4 = moderate, 5 = severe) for both tonometers, and patients were asked which tonometer they preferred. |
