Glaucoma is known to be a progressive optic neuro-pathy that causes characteristic visual field defects and is associated with several known risk factors including elevated intraocular pressure. Accurate examination of the optic nerve head is crucial for diagnosing and following patients who have or are suspected of having glaucoma. Structural deficits in the optic nerve often precede functional abnormalities (“pre-perimetric glaucoma”). The emergence of several new optic nerve imaging technologies provides clinicians with more objective, quantitative methods of evaluating the optic nerve head. This review of the clinical applications of the Heidelberg Retina Tomograph II imaging system (Heidelberg Engineering GmbH, Dossenheim, Germany) describes the rationale that led to the development of this device, provides an overview of the technical components of the system, and outlines how it may be a useful tool in clinical practice.
