[Statistical evaluation of the role of elevated intraocular pressure and weakened accommodation in progressive...

Ophthalmic tone was examined by Goldman's tonometry in 186 subjects (372 eyes) aged 13-35 with myopic and emmetropic refraction, as was the status of relative accommodation reserve. The findings evidence that in progressive myopia the mean level of intraocular pressure is by 3.0 mm Hg higher than ophthalmic tone in the eyes with emmetropic and stationary myopia; the relative accommodation reserve index was found decreased in 80-87 percent of patients with slowly and gradually progressing myopia, whereas in those with emmetropic and stationary myopia it was normal. This lead the authors to a conclusion that relatively elevated intraocular pressure (greater than or equal to 16 mm Hg, measured according to Goldman) and poor accommodation are factors indicating the risk of myopia progress and essentially influencing the refraction enhancement at this age.
