A model of streamer propagation is considered. Analytical expressions for the velocity, length and width of the streamer are derived. The velocity of the streamer is proportional to its length, and the width of the streamer is proportional to the square root of its length. The results obtained are in good agreement with experiment. Mechanisms which may act as secondary processes in the streamer breakdown of gases are discussed.

Introduction. According to the World Health Organization (WHO), glaucoma accounts for 4-5% of the total ocular pathology, making it one of the most common eye diseases in the world. The first sign of the disease is a constant or periodic increase in intraocular pressure, which leads to the development of visual field defects, optic nerve atrophy, and dystrophic changes in eye tissues. Detection of glaucoma and ocular hypertension is done by measuring the intraocular pressure, which is the standard procedure for diagnosis of the condition of eyes in all patients over 40 years of age. Patients with a diagnosis of "glaucoma" should constantly measure the intraocular pressure, which is necessary to control the effectiveness of treatment, its correction and evaluation of the effectiveness of drugs. The purpose of the article is to develop the system for assessing the intraocular pressure level using the interference pictures parameters observed on the eye cornea in the polarized light.
