Fundus image for neurologists

Purpose. We describe in detail a relatively simple technique of fundus photography in human and rabbit eyes using a smartphone, an inexpensive app for the smartphone, and instruments that are readily available in an ophthalmic practice. Methods. Fundus images were captured with a smartphone and a 20D lens with or without a Koeppe lens. By using the coaxial light source of the phone, this system...

The paper presents an imaging reflectometer designed to detect flicker-induced reflectance changes of the ocular fundus. The system is based on a modified fundus camera completely controlled by a personal computer via USB interface. The system allows in-vivo functional imaging of the ocular fundus in the near-infrared region with flicker light stimulus in the visible spectrum.

In this paper the new method for automatic segmentation of cup region from fundus eye images taken from classical fundus camera. The proposed method which is based on fuzzy clustering algorithm is a first step in automatic classification of fundus eye images into normal and glaucomatous ones.
