General Opinion

Recently, much literature data is available on the issue of diagnosis of preperimetric glaucoma (PPG), but no recognized algorithms of detecting primary open-angle glaucoma (POAG) at this stage have been developed, and there is no general opinion as to what parameters and techniques should be used. The review offers a generalization of the literature data on PPG diagnosing and specifies the main parameters that should be taken into account in testing POAG patients at the early preperimetric stage. As is known, the diagnosis of glaucoma is based on detectable changes in the optic nerve head and visual field, but the onset of the disease occurs long before the above changes. Currently, the approach shifts towards early OCT diagnosis of glaucoma. Cohort studies show that structural disorders are detected 5–12 years earlier than functional ones in 17–60 % patients with POAG.

The leading place in the structure of blindness and low vision is occupied by two diseases: primary open-angle glaucoma and diabetic retinopathy. The combination of two diseases in one eye gives an even more severe prognosis for vision. Modern diagnostic equipment helps in accurate and early diagnosis of the disease by analyzing digital data of the optic nerve head and macular area of the retina according to the results of an optical coherence tomograph. A mathematical model for predicting the development of diabetic retinopathy and primary open-angle glaucoma according to the proposed mathematical criteria has been developed. The criteria represent the ratio of the integral area of the neuroretinal rim to the integral volume of the neuroretinal rim; the retinal thickness criterion and criterion of the primary open-angle glaucoma and diabetic retinopathy are calculated. A computer program has been developed. The algorithm of the program, which includes windows for entering digital data of the macular zone and parameters of the optic nerve head, is presented. The result of the program is the statement of the risk of developing combined pathology of the fundus in a particular patient.
