Abstract . GHT OUTSIDE NORMAL LIMITS ON AT LEAST TWO OCCASIONS -OR-Minimum Criteria for Diagnosis of Glaucoma VF Defect (HODAPP, ET AL, 1993) 2. Optical coherence tomography was first described in 1991 for imaging the retina and retinal pigment epithe-lium. Scanning laser polarimetry (SLP) and optical coherence tomography (OCT) allow quantitative measurements of the RNFL thickness around the ONH . In this test, a laser light is used to scan the internal structures of retina, and in the case of glaucoma, early changes to the nerve fiber layer thickness can be revealed even before visual field or other tests detect changes. The ability to detect structural loss is fundamental in the diagnosis and management of glaucoma. Red-free fundus photographs of the posterior pole by stereo-biomicroscopy or with digital red-free photography can aid in evaluating the RNFL. Since it is a disease which can be treated but not cured, it is crucial for the treating ophthalmologist to catch the disease as early as possible.
