PARAMETERS OF CHOROIDAL BLOOD FLOW IN IDIOPATHIC MACULAR RUPTURE
Purpose: to study the features of choroidal blood flow in patients with idiopathic macular ruptures. 37 patients (47 eyes) with idiopathic macular ruptures, 32 women and 5 men were examined between 2006-2013. Mean age was 63±13 years old. The control group consisted of 15 people (30 eyes) of similar age without retinal pathology. Hemodynamic characteristics of choroidal blood flow was determined in three zones: medial to the optic nerve head, medial to the fovea (between the fovea and optic nerve head) and lateral to the fovea. No significant changes in choroidal blood flow indicators medial to the optic disc in patients with idiopathic macular ruptures have been identified. Analysis of the choroidal hemodynamics lateral and medial to fovea showed a significant reduction in all blood flow velocity indices compared with the control group. More pronounced changes were established in lateral to the fovea, where the maximum and average linear velocity of blood flow decreased by 1.5-2 times compared to the control group and the peripheral resistance index tended to increase.
