The Hemodynamics of the Myopic Eye: Rheo-oculographic Findings
With the technique developed at our clinic, rheo-oculography has proven to be a sensitive means for the sphygmodynamic investigation of the eye (rheo-oculography with a definite time constant) and is the only means available in clinical practice for blood flow measurements, even if semiquantitative (rheo-oculography with an infinite time constant).
Forty-five patients with pathological axial myopia, 32 patients with simple myopia and 26 controls were examined with our technique. From the results there emerged a clear, statistically significant, rheo-oculographic picture of pathological axial myopia characterized by flow indexes that were consistently lower than both the controls and the patients with simple myopia. The ocular pulse showed a marked reduction in amplitude, a clear decrease in speed, and a convex descending branch on the rheo-oculogram. These characteristics appear to correspond well in functional terms to the anatomicopathological alterations of the retinochoroidal vessels.
