Abstract

The purpose of this paper is to estimate the influence of melanosomes in the anterior chamber of the eye on the results of short laser pulse action on the eye biotissue in the case of glaucoma of adult patients and children. In the case of glaucoma of adult patients the biotissues in the anterior chamber of the eye mostly contain melanosomes (pigmented granules), which act as absorbing inclusions when irradiated with laser pulses. In contrast to the eye of adult in the case of hydrophthalmia (congenital glaucoma), there are practically no melanosomes in the anterior chamber of the children’s eyes. A model is proposed for the heating of a pigmented melanosome in eye biotissues by a laser pulse. Analytical and numerical calculations based on this model are made.
