FIELD: medicine, ophthalmology.
SUBSTANCE: one should detect the following ocular parameters: the depth of anterior chamber of the eye, the thickness of lens and the length of anterior-posterior ocular axis to calculate the ratios of parameters between each other to obtain the value for glaucoma prediction. The value for glaucoma prediction should be calculated as the ratio of lenticular thickness against the depth of anterior chamber and the length of anterior-posterior ocular axis by the following formula: 
where t - the thickness of lens; h - the depth of anterior chamber; l - the length of anterior-posterior ocular axis; 145 - the constant. At the value being equal or above 10 one should predict primary narrow-angle glaucoma.
EFFECT: higher efficiency of prediction.
