Beschreibungen/Notizen

• •With spectral domain optic coherence tomography technology, retinal and deeper choroidal tissues can be tested easily and quickly.•Patients with coronary slow phenomenon have thinner subfoveal choroidal thickness than patients with microvascular angina and healthy controls.•Patients with coronary slow phenomenon had thinner superior and inferior quadrant of peripapillary retinal nerve fibre layer thickness compared to patients with microvascular angina and healthy controls.•The superior peripapillary retinal nerve fibre layer thickness was independently associated by presence of coronary slow flow phenomenon (β=-0.379, p < 0.001). Thus, spectral domain optic coherence tomography might be useful to detect the early glaucoma in patient with coronary slow phenomenon.•Coronary slow phenomenon is not only affecting the coronary vessel, but it can also affect the peripheral vessel. Impairment of blood flow regulation and increased microvascular resistance in CSFP may cause decreased in ocular blood flow. The aim of this study was to evaluate and compare the subfoveal choroidal thickness (SFCT) and peripapillary retinal nerve fiber layer thickness (pRNFLT) in patients with microvascular angina (MA), coronary slow flow phenomenon (CSFP) and healthy controls. Thirty-two consecutive patients with MA, 35 consecutive patients with CSFP and 40 age and sex-matched controls were enrolled. SFCT, average pRNFLT and four quadrants of pRNFLT were measured by spectral domain- optical coherence tomography (SD-OCT). The mean SCFT in patients with CSFP (267.57 ± 30.61 μm) was significantly thinner than those of patients with MA (288.84 ± 28.25 μm) and control (291.21 ± 31.75 μm) (p = 0.002) while SFCT of patients with MA were similar with those of controls. Patients with CSFP had thinner superior and inferior pRNFLT compared to patients with MA and controls (p < 0.001 and p = 0.005, respectively) while there were no significant differences in average pRNFLT, nasal and temporal quadrant of pRNFLTs among three groups. In the multivariate linear regression analyses, the presence of CSFP was found negatively correlated with SFCT and superior pRNFLT. Patients with CSFP had thinner SFCT, superior and inferior quadrants of pRNFLT proposing the presence of a generalized endothelial dysfunction and increased microvascular resistance in these patients.
