to compare two techniques used for assessment of optic nerve damage in glaucoma patients and to find whether those methods are complementary or can substitute each other. Method: this is a prospective study conducted at king Hussein Medical Centre between April 2014 and July 2014. All patients diagnosed to have primary open angle glaucoma were enrolled in this study. Patients with unreliable automated perimetry and patients with past history of retinal or optic nerve diseases were excluded from the study. Optical coherence tomography and Humphrey automated perimetry will be performed to all patients on each visit. The data obtained was analyzed and compared. Results: 250 patients (410 eyes) with galuacoma aged between 37 and 75 years. OCT was able to detect glaucomatous damage in 94.6% of glaucoma patients. It detected the damage in 93.6%, 96.1% and 97.6% of eyes with mild, moderate and severe cases respectively. The agreement between the two instruments was 91.9%, 94.2% and 97.6% in mild, moderate and severe cases respectively. Conclusion: OCT proved to have a very good agreement with Humphrey automated perimetry and it can be used instead of HAP for assessment the wellness of optic nerve fibers especially when there is any limitation in interpretation of HAP images.
