Intraocular fluid contrasting is achieved via subconjunctival injection of 0.1 ml of 1% sodium fluorescein solution then diffusing along the outflow tract through the anterior chamber. Then the area concerned of the drainage tracts is photographed by means of a slit lamp completed with a digital camera operating in the infrared photographing mode and with a system of special filters, which makes it possible to enhance the sensitivity of the system to the spectrum of fluorescein irradiation. A series of the images made before and at a certain temporal interval after administration of the contrast substance is analyzed by using the original computer program "Digital Differential Fluorescein Study of the Ocular Drainage Tract". The result of the analysis is the possibility of functional characterization of the intraocular fluid outflow tract in the area under study. The procedure yields a picture of the relative hydrodynamic activity of drainage collectors located in any perisuperficial structures of the eye. |
