Visual field (VF) testing is an important diagnostic tool for Glaucoma. The current gold standard for VF testing is automated perimetry. This article is an attempt to familiarize the reader with components of an achromatic (white on white) automated perimetry printout. It addresses use of Humphrey perimeter to interpret the results. For the purpose of this review, a PubMed search was made using perimetry, Humphrey VFs review as key words and the relevant articles were studied. The references appended with these articles were also analyzed, and any appropriate article was also included. A systematic approach has been outlined that results in a thorough interpretation of the printout. One should be able to identify a normal field and establish glaucomatous progression, detect the presence of a field defect, determine whether it is due to glaucoma or neuro‑ophthalmic disease if any. Comprehensive evaluation using clinical examination, tonometry, and perimetry should be considered together to make a proper diagnosis of glaucoma and judge its progression over time.
