Correlation of Ocular Pulse Amplitude, Choroidal Thickness, and Internal Carotid Artery Doppler Ultrasound Findings in Normal Eyes.

Introduction: The choroid receives about 65-85% of ocular blood flow, which comes from the ophthalmic artery (OA), the first branch of the internal carotid artery (ICA). In the foveal avascular zone, there is no retinal vascular supply; therefore, choroidal blood supply plays a significant role in this subfoveal region. The ocular pulse amplitude (OPA) provides useful information about intraocular blood flow and is an indirect indicator of choroidal perfusion.

Macular ganglion cell complex thickness in acute and chronic central serous chorioretinopathy.

Central serous chorioretinopathy (CSCR) is characterized by neurosensory retinal detachment. Because the retina pigment epithelium and choroidal pathology is the current mechanism in CSCR, many studies in the literature focused on the outer retinal layers. There is little information about the functional or histological structure of the detached retina.
