Opis:: This contribution presents an application of frequency-domain optical tomography to ophthalmology. Essential theoretical foundations of time-domain and frequency-domain optical tomography are presented. Images of sections through the anterior chamber, the corneo-scleral angle and fundus of the eye are reconstructed from the spectral fringes. The morphological information gained by tomograms is important for diagnosing and planning of a treatment of glaucoma.

Opis:: Purpose of this work is to introduce results of biological objects measurements with Optical Coherence Tomography system working with swept source laser (OFDI system). This specified source with spectrum centred around 1040 nm is dedicated to measure posterior segment of the eye. OCT with this wavelength is expected to be next generation for this sort of systems. Although commonly used 800 nm source enables imaging retina, deeper tissue layers are not available with this wavelength. Longer wavelengths in range of infrared spectrum (e.g. 1040 nm) are being weakly scattered which enables to go down to the choroid layer [1]. Examination this structure composed mostly from blood vessels might be very important for early diagnosis of eye diseases. In this paper system setup, swept source scheme and eye images would be introduced.

Opis:: The nervous system's ability to receive light stimuli and its' processing in the brain in order to produce a visual impression is the definition of the sense of sight. The anatomical form of the sense organ of vision is comprised of the eyeball, the eye's protective apparatus, the eye's movement apparatus and the retinal nerve connections made to structures in the brain. The shape of the eye's lens, which gives the eye its refraction ability, depends on the voltage present in Zinn's ligaments that regulate the ciliary muscle. Sharpness of vision is produced by changing the shape of the lens, a reflexive adjustment. A domed lens causes stronger light inflexion and allows a sharp visual appearance of close objects. A flattening of the lens results in less light refraction and the seeing of more distant objects. The lens consists of a capsule, a cortex and a nucleus and it has two convex surfaces: the front and the rear. If we imagine the lens as a plum fruit, the capsule is its skin, the cortex is its flesh and the nucleus is its stone. Proper functioning of the lens is essential for accurate vision. Exact assessments of the eye's lens and the ability to monitor the status of associated diseases are extremely important. The lens may be tested using a slit lamp, but in any situation where an eye disease prevents this assessment of the lens this examination will obviously be inadequate. Thanks to today's imaging techniques, we can now assess the anatomical arrangement and condition of the lens, even in the eyes of those patients for whom the use of an imaging lens slit lamp is not possible [1, 2].

Opis:: Digital fundus eye images may reveal essential features being important for the diagnoses of many pathologies once they are correlated with other specific medical data. A proposal of a comprehensive application referring both to the images and various additional medical data has been briefly described and discussed.

Opis:: In this paper the methods for selecting of the most important parts of the human eyes are described. On the basis of the real 21 channel multispectral images the model of finding the lens and the spot are defined. These methods are based on the most popular algorithms of image processing. The approach to veins detection is still undefined but in the article the most important channels are pointed out and the channel difference between eyelash and the veins is also mentioned.
