FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to ophthalmology, and aims at predicting the maximum daily variations of the intraocular pressure (IOP) in patients with ocular manifestations of pseudoexfoliative syndrome (PES). Ocular PES is staged. The IOP and average blood pressure (BPav) are measured. The presence or absence of myocardial infarction in the past medical history is stated. The maximum daily variations of the IOP (ΔIOPmax) is calculated by formula: ΔIOPmax=0.37*PES+0.89*MI+0.029*BPav+0,123*IOP-1.95, wherein: PES is the PES stage falling within the range of 1 to 3; MI is the myocardial infarction in the past medical history, 1 - yes, 0 - no; BPav is the average blood pressure, mmHg calculated as (systolic blood pressure + diastolic blood pressure)/2, and IOP is the initial IOP, mmHg measured three times at the moment of initial polyclinic consultation to calculate an average value of the calculations; 1.95 is an independent constant.
EFFECT: method enables the accurate measurement of maximum daily variations of the IOP accessible in polyclinics in the patients suffering from PES taking into account both local factors (PES stage, IOP value), and peculiarities of the general patient's somatic status (blood pressure, myocardial infarction in the past medical history).
