2M.D. Kagizman State Hospital, Eye Clinic, Kars/TURKEY Purpose: The aim was to evaluate the circadian rhythm of intraocular pressure in glaucoma patients and patients with glaucoma suspect using the Sensimed Triggerfish® system.
Materials and Methods: The Sensimed Triggerfish® system was applied to nine patients. Before the application, a full ophthalmic examination was performed in all patients. Patient graphics were evaluated for diurnal variation and peak intraocular pressure.
Results: The patient diagnoses were pseudoexfoliation glaucoma (4 patients/44.4%), glaucoma suspect with pseudoexfoliation (3 patients/ 33.4%), primary open angle glaucoma (1 patient/11.1%), and pigmentary glaucoma (1 patient /11.1%). Two patients (22.2%) could not complete the 24-h measurement. After the application, the treatment modalities of four (44.4%) patients were changed. All had a diagnosis of pseudoexfoliation glaucoma. In addition, medical treatment was prescribed to two (22.2%) glaucoma suspect with pseudoexfoliation patients. All curves of patients with pseudoexfoliation showed an elevation during the nocturnal period and the peak intraocular pressure curves were observed between 01:00-09:00.
Conclusion: A 24-h intraocular pressure measurement is important for the diagnosis of glaucoma, the selection of treatment modality, and the evaluation of treatment efficacy. Keywords : Diurnal variation, glaucoma, sensimed triggerfish system
