Ophthalmoergonomic Test “Glazomer”: Clinical Standardization, Application Prospects

Purpose . Clinical standardization and assessment of the prospects for using the ophthalmoergonomic test “Glazomer” (TG) in a comprehensive examination of the functional state of the visual analyzer of patients engaged in visually intense work (VST). Methods . The test methodology involves sequentially presenting geometric figures (square, circle, rhombus, etc.) on a computer screen that have signs of geometric symmetry and a circumscribed circle diameter of 4–7 cm (angular size of 3.8–6.70 from a distance of 60 cm). The patient’s task was to position the cursor in the center of the figure and fix this position using the “mouse”. There were 12 figures, the presentation time was unlimited or 3, 5 and 10 seconds. The study involved 34 male volunteers aged 28–36 years (mean age 32.4 ± 1.1 years) with no visual organ pathology and cognitive impairment. Based on the study results, two parameters were calculated to assess the accuracy of the eye: the average value of the positioning error — the deviation from the test object center (VOC, mm) and the standard deviation of the error — the spread value (SV, mm). Results . The data obtained indicate that with a decrease in the test presentation time, there was a deterioration in the accuracy of the eye. At the same time, the standardized indicators for the TG are: VOC — no more than 2.54 mm; SV — no more than 0.52 mm. It is important to emphasize that the accuracy of the eye under time “deficit” (3 sec) is a sufficiently informative indicator that determines, along with traditional approaches, the clinical effectiveness of the proposed technologies for treating VST patients with cataracts and accommodative asthenopia after refractive (LASIK) surgery. In particular, it has been established that the presence of anisometropia in a patient after surgical intervention is accompanied by a significantly more pronounced (compared to patients without anisometropia) deterioration in visual performance under conditions of time “deficit”. Conclusion . Practical implementation of TG in a comprehensive examination of the functional state of the visual analyzer of patients with VST with cataracts or accommodative disorders will ensure an increase in the level of diagnostics from the standpoint of the “medical and social” health model.
