Abstract

Purpose : To investigate by optical coherence tomography angiography (OCT-A) the vascular response of macular neovascularization (MNV) to an experimentally increased blood pressure (BP) in patients with chronic central serous chorioretinopathy (CSCR).

Methods : In this multicenter, observational study, 32 patients with an established diagnose of neovascular CSCR were enrolled. All subjects underwent a hand-grip isometric test (HGT) for three minutes. In the resting phase and during the physical effort macular OCT-A scans were acquired using the Spectralis OCT-A. Systemic hemodynamic data were recorded at baseline and during stress conditions using an electronic sphygmomanometer. On OCT-angiograms qualitative and fully automated quantitative analyses of the MNVs were performed. The results were then correlated with those of the hemodynamic assessment.

Results : Under stress data of systolic BP, diastolic BP, mean arterial pressure (MAP) and ocular perfusion pressure (OPP) were significantly higher (p<0.05) than baseline ones, reaching values in the range of hypertension. The qualitative analysis of MNV OCT-angiograms evidenced numerous microcirculatory changes during the HGT. A significant increase (p<0.05) of MNV area and fractal dimension and a significant reduction of the lacunarity index were seen in all MNV lesions during the HGT. Mean values of baseline MAP and OPP showed a positive linear correlation with the vascular perfusion density of the MNVs.

Conclusions : Results of the present study suggest that during physical stress patients with this neovascular CSCR easily reach critical values of blood pressure that have a direct impact on MNV perfusion. This phenomenon might potentially increase the risk of an actively exudating neovascular lesion.
