| Abstract Background: Testing of the visual field remains the primary basis for evaluating glaucomatous visual function. Recently there have been innovations for perimetry that enhance its clinical utility the visual field was first measured by Thomas Young, in 1825, the outer aspect extends approx-imately 50º superiorly, 60º nasally, 70º inferiorly and 90º temporally. Aim of Study: To compare visual field examination pa-rameters, Mean Deviation (MD), Pattern Standard Deviation (PSD) in glaucoma patients performed on two different devices: Heidelberg Edge Perimeter (HEP) and Humphrey Visual Field analyser (HVF). Patients and Methods: This is a randomized prospective, comparative, study conducted on thirty four eyes diagnosed as primary open angle glaucoma, those patients were recruited from the ophthalmic outpatient clinics at Rod-elfarag ophthal-mic hospital in Cairo & Imbaba Ophthalmic Hospital in Giza at time between May 2016 to June 2017. They had reliable visual field test and controlled by anti-glaucoma treatment without any other cause of secondary increased Intra Ocular Pressure (IOP), any surgical or laser intervention. Results: There were a total of thirty four eyes where visual field examination by Heidelberg Edge Perimeter (HEP) and Humphrey Visual Field analyser (HVF) revealed no statistically significant difference between two perimeters except in severe glaucoma in which HVF showed more increase in PSD than HEP. Conclusion: HVF tend to presents an increase in the level of PSD in severe glaucomatous defect than those measured by HEP. | ||||
