Abstract

A retrospective study aimed to detect progression of visual field changes in early open angle glaucoma, and to determine how often a perimetric exam should be carried out and also its effect on the current treatment of the patient.Patients diagnosed with relatively recent manifestations of POAG were called for perimetric examination every 3 months. PLR criteria was used to determine progression.Patients were divided into high frequency and low frequency groups.and statistical analysis was performed to look for significant change of mean deviation over time.Results: A total 50 eyes were included in study.Statistical analysis of high frequency patients showed significance (more reliable, p value=0.007) whereas the low frequency group did not show significance (less reliable, p value=0.19) when only half the fields were considered. Conclusion: Perimetric examination must be done every 3 months instead of 6, especially in patients with early manifest primary open angle glaucoma.
