There are many conditions that can mimic glaucoma. It is important to be aware of the differential diagnosis so that other conditions that can present with visual field defects and/or optic neuropathy can be detected and dealt with promptly. External ocular, retinal, optic nerve, systemic and visual pathway problems can present with features of glaucoma. A careful history and thorough examination will guide the clinician to making the correct diagnosis. Particuar emphasis should be made on the pattern of visual field defects, the optic disc cupping versus palor and whether the disc appearance correlates with the visual field defect. Timely medical advice should be sought to avoid sight/life-threatening conditions in some of these cases.
