To assess, primarily, the impact of office-hours diurnal IOP measurements on our clinical treatment attitude for glaucoma patients. Secondly, to determine, specific risk factors which allow us to select the group of patients where performing an IOP diurnal curve can be useful.


20 patients were included in this retrospective study. We examined the files of the patient who underwent a diurnal IO pressure curve between 01/01/2012 and 01/03/2013. Age, gender, race, diagnosis, the ophthalmological surgical and medical history, number of IOP measurements and the length of the diurnal curve on the examination day, the min and max IOP, and finally the therapeutic impact of these measurements and change in the treatment of patients.


The mean age was 58.6 ± 14.8 years. There was min 4 to max 5 IOP measurements during 8.4 ± 0.5 hours. The mean IOP of all the patients was 17.7 ± 3.2 mmHg with a variation 2.3 ± 1.4 mmHg (1 to 6 mmHg max) during the day. There were only 50% of the measurements which led to a change of the clinical treatment. In this group of patients the higher max IOP during the day and the higher IOP variation were the common feature.


In our study we found that only 50% of the office-hours diurnal intraocular pressure curve led to a new clinical treatment. The patient selection should be stricter because of the time-consuming examination. Patients with higher IOP should be taken into account for diurnal IOP measurements where there are signs of progression.
