TRANSPALPEBRAL TETRAPOLAR REOOPHTALMOGRAPHY IN THE ASSESSMENT OF PARAMETERS OF THE EYE BLOOD CIRCULATORY SYSTEM

Cover Page

Abstract


Background: Quantitative assessment of hemodynamic parameters is an important element of ophthalmic diagnostics especially in early detection of myopia, glaucoma, diabetic retinopathy. The assessment of hemodynamic changes is essential in evaluating of the efficiency of treatment. Objective: Our aim was to determine the adequate of eye hemodynamics assessment using reoophtalmography in patients with various clinical refractions. Methods:  A controlled study was carried out. All tests were performed using transpalpebral tetrapolar method. Signal registration lasted for 20 seconds in the supine position, and then the diagnostic parameters were calculated. Results: We present the results of examination of 76 patients aged 5 to 22 years (average age 13.0±1.1). 32 patients had low myopia (62 reoophtalmography records), 23 patients had moderate myopia (42 records) and 5 patients had high myopia (12 records). The control group was composed of 16 patients. The main differences were found in the rheographic index, which is equal to 58.1±4.1 mOhm in the control group. It is significantly reducing with refraction increase, from 47.8±3.2 mOhm in low myopia to 34.0±2.5 mOhm in high myopia (p =0.050). This is an evidence of blood supply deficiency in the myopic eyes. Conclusion: Rheographic index was shown to differ in different breathing phases, which agrees with the known physiological regularities. The proposed method is highly informative and sufficiently accurate what allows assessing the eye blood supply state objectively. It is easy to apply and requires no contact with the eye surface, which is especially important in pediatric practice.
