This work consists in the mathematical analysis, to establish a correlation between the increase of the intraocular pressure and the central thickness of the cornea, our database was acquired from both sick and healthy patients of the “Santa Lucia” clinic from the city of Quito, which complied with some rules of inclusion and exclusion that are presented later, this database was segmented based on false positives and false negatives, this was done to handle our data in a reduced way. After applying different types of interpolation, we obtained an equation that relates both to the intraocular pressure and the central thickness of the cornea, then analyzed the behavior of the equation against different types of data, both sick people and healthy people. The results obtained were encouraging, since with the identification of glaucoma at an early stage, the number of people who can lose their sight permanently will be reduced.
