ABSTRACT

Due to the RNFL atrophy is one of the first signs of glaucoma that can be visible in fundus images, many authors try to assess the visual appearance of RNFL using fundus images in their publications. An attempt to utilize fundus camera for evaluation of RNFL has been first introduced in 1980 (Lundström et al. 1980). Black and white photographs were used for qualitative evaluation of the RNFL texture. Then, the other authors have been investigating the same photographs in more or less similar way (Peli 1989, Tuulonen 2000 & Lee 2004). In the case of glaucomatous damage, RNFL appears darker in fundus images. Thereby, many authors try to involve only an intensity criteria for decision tasks towards detecting glaucomatous changes, even in the recent state in this field of applied research (Hayashi 2007, Muramatsu 2010, & Prageeth 2011).
