[Optic disc photography and retinal nerve fiber layer photography]

(Papillenfotografie und retinale Nervenfaserschichtfotografie.)

Full Abstract

In addition to optic disc assessment at the slit lamp and the use of imaging devices for glaucoma diagnosis, optic disc photography is widely used in clinical practice. The advantages of stereophotography are a permanent recording of the optic disc status especially used for serial evaluation of discs, good visibility of the peripapillary region and a relatively fast examination without pupil dilation (if using non-mydriatic fundus cameras). The limitations are the need for clear media, pupil dilation, a skilled photographer and the delay involved.Retinal nerve fiber layer (RNFL) photography is based on the absorption of green light by melanin in the retinal nerve fiber layer. In comparison to scanning laser devices this methodology is not as convenient and requires widely dilated pupils and high levels of competence by technical personnel. Furthermore, the examination with RNFL photographs requires considerable learning and experience. RNFL photography detects glaucoma damage before visual field defects occur.
