“…CSC is associated with pathophysiological changes in choroidal circulation and morphology [13,14]. A recent optical coherence tomography angiography (OCTA) report showed characteristics, such as enlargement/distortion of the foveal avascular zone, dark areas (neurosensory detachment/pigment epithelial detachment), dark spots (pigment epithelial detachment), abnormal vessels (dilated vessels/choroidal neovascular membranes), and choriocapillaris island [17]. Reports also indicate that CSC shows increased sympathetic activity, decreased parasympathetic activity, altered sympatheticparasympathetic balance, and decreased parasympathetic responsiveness [18].…”

Purpose: This study aimed to assess the course of changes in choroidal morphology after immersion of the foot in warm water at 40°C using enhanced depth imaging optical coherence tomography (EDI-OCT). Methods: Forty-three right eyes of 43 healthy participants were included. Changes in choroidal morphology were determined using EDI-OCT to evaluate subfoveal choroidal thickness (SCT). Systolic, diastolic, and mean blood pressures (SBP, DBP, and MBP, respectively) were also measured to determine systemic circulatory dynamics at baseline, immediately after immersion (0 min), and 10, 20, and 30 min after immersion. Results: Immediately after immersion, SBP, DBP, and MBP were significantly declined versus baseline. In contrast, the SCT was significantly increased after warm water immersion. However, all these parameters did not change significantly compared to the baseline within 30 min. Conclusion: In the normal eye, parasympathetic nerve activity induced by warming stimuli increases choroidal morphology in response to a decrease in systemic circulatory activity, which normalizes within 30 min. The findings of this study may provide basic data for the prevention and treatment of various choroidal diseases in which sympathetic hyperactivity is involved in the pathogenesis.

“…42 The region of strong blood flow signal in the choriocapillaris layer corresponds primarily with the hyperperfused zone in ICGA and is marked by vascular dilation and increased blood flow; regions of weak blood flow signal frequently appear as shadows with a decreased flow density, typically matching the areas of retinal or RPE detachment. 43 In contrast, for chronic CSC, OCTA may reveal local filling defects at the level of the choriocapillaris, accompanied by dilated arterioles and venules, which may persist even after the regression of the SRD. 42 For chronic CSC, the diagnosis of concurrent CNV is challenging.…”
