A total of 92 patients (92 eyes), including 52 patients with early-stage primary open-angle glaucoma and 40 glaucoma suspects, were enrolled in the study and followed up during 25.5±3.3 months on the average by means of computer perimetry, optical coherence tomography and Heidelberg retinal tomography. The prognoses for POAG progression made on the basis of these tests using both conventional (conservative) and extended (liberal) evaluation criteria demonstrated poor correspondence. It is suggested to consider glaucoma progression confirmed if characteristic changes are registered by at least two of the three methods.
