Abstract
The aim of this study was to study the retinal vessels in patients affected by vasculogenic erectile dysfunction (ED), using dynamic vessel analyzer (DVA). Patients with vasculogenic ED and control subjects were prospectively enrolled to undergo a complete urological and ophthalmologic evaluation, including DVA and structural optical coherence tomography (OCT). The main outcome measures were: (1) arterial dilation; (2) arterial constriction; (3) reaction amplitude (the difference between arterial dilation and constriction); and, (4) venous dilation. Thirty-five patients with ED and 30 male controls were included in the analysis. Mean ± SD age was 52.0 ± 10.8 years in the ED group and 48.1 ± 16.3 years in the control group (p = 0.317). In the dynamic analysis, the arterial dilation was lower in the ED group (1.88 ± 1.50%), as compared with the control group (3.70 ± 1.56%, p < 0.0001). Neither arterial constriction nor venous dilation differed between groups. The reaction amplitude was decreased in ED patients (2.40 ± 2.02%, p = 0.023), compared to controls (4.25 ± 2.20%). In the Pearson correlation analysis, the ED severity, was directly correlated with both reaction amplitude (R = .701, p = 0.004) and arterial dilation (R = .529, p = 0.042). In conclusion, subjects with vasculogenic ED are featured by a significant dysfunction of the retinal neurovascular coupling, which is inversely correlated with ED severity.

Retinal Microvascular Changes in Familial Hypercholesterolemia: Analysis with Swept-Source Optical Coherence Tomography Angiography. J Pers Med 2022; 12:jpm12060871. [PMID: 35743656 PMCID: PMC9224994 DOI: 10.3390/jpm12060871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Revised: 05/18/2022] [Accepted: 05/25/2022] [Indexed: 02/01/2023] Open
Abstract
Familial hypercholesterolemia (FH) is a common but underdiagnosed genetic disorder affecting cholesterol metabolism, leading to atherosclerotic disease. The relationship between retinal microvascular changes and the presence of atheroma in patients with FH (FH group), and in comparison to volunteers without FH (CT group), needs further investigation. This cross-sectional study was conducted in a university hospital between October 1, 2020 and May 31, 2021. Cardiovascular data, including the Coronary Artery Calcium (CAC) score, were recorded for FH patients. Macula angiograms were acquired using swept-source optical coherence tomography angiography (SS OCT-A) to analyze both the superficial capillary plexus (SCP) and deep capillary plexus (DCP). A total of 162 eyes of 83 patients were enrolled in the FH group and 121 eyes of 78 volunteers in the CT group. A statistically significant association was found between the CAC score and both vessel density (β = −0.002 [95% CI, −0.004; −0.0005], p = 0.010) and vessel length (β = −0.00005 [95% CI, −0.00008; −0.00001], p = 0.010) in the DCP. The FH group had a significantly lower foveal avascular zone circularity index than the CT group in multivariate analysis (0.67 ± 0.16 in the FH group vs. 0.72 ± 0.10 in the CT group, β = 0.04 [95% CI, 0.002; 0.07], p = 0.037). Retinal microvascularization is altered in FH and retinal vascular densities are modified according to the CAC score.

Early manifestation of aging-related vascular dysfunction in human penile vasculature-A potential explanation for the role of erectile dysfunction as a harbinger of systemic vascular disease. GeroScience 2022; 44:485-501. [PMID: 34962617 PMCID: PMC8811115 DOI: 10.1007/s11357-021-00507-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 12/22/2021] [Indexed: 01/05/2023] Open
Abstract
Advanced age is related to functional alterations of human vasculature, but erectile dysfunction precedes systemic manifestations of vascular disease. The current study aimed to simultaneously evaluate the influence of aging on vascular function (relaxation and contraction responses) in systemic human vascular territories: aorta (HA) and resistance mesenteric arteries (HMA) and human corpus cavernosum (HCC) and penile resistance arteries (HPRA). Associations of oxidative stress and inflammation circulating biomarkers with age and functional responses were also determined. Vascular specimens were obtained from 76 organ donors (age range 18-87). Four age-groups were established: < 40, 40-55, 56-65 and > 65 years old. Increasing age was associated with a decline in endothelium-dependent relaxation induced by BK in HMA (r = -0.597, p = 0.0001), or by ACh in HCC (r = -0.505, p = 0.0022), and HPRA (r = -0.601, p = 0.0012). Significant impairment was detected at > 65 years old in HMA but earlier in penile vasculature (> 55 years old). Age-related reduction to H2O2-vasodilatory response started before in HCC (56-65 years old) than in HA (> 65 years old). In contrast to relaxation responses, aging-related hypercontractility to adrenergic stimulation was homogeneous: contractions significantly increased in subjects > 55 years old in all tested vessels. Although not significantly age related, circulating levels of ADMA (r = -0.681, p = 0.0052) and TNF-α (r = -0.537, p = 0.0385) were negatively correlated with endothelial vasodilation in HMA but not in HCC or HPRA. Penile vasculature exhibits an early impairment of endothelium-dependent and H2O2-induced vasodilations when compared to mesenteric microcirculation and aorta. Therefore, functional susceptibility of penile vasculature to the aging process may account for anticipation of erectile dysfunction to systemic manifestations of vascular disease.

Abstract
SIGNIFICANCE Regular physical activity may affect the neurovascular structures. Many studies have shown the positive effects of physical activity on ocular disorders such as glaucoma, retinopathy, and macular degeneration. Athletes were expected to have a better retinal vascular structure compared with the nonathletes. PURPOSE This study aimed to evaluate the effects of regular physical activity on the retinal microvascular structure. METHODS This observational and cross-sectional study was conducted between January and July 2020 with participants aged 20 to 35 years who had a visual acuity of ≥20/20, axial length of 22 to 24 mm, refractive defect spherical equivalent of ≤±1 D, and IOP of ≤21 mmHg. Updated AngioScan software (Navis version 1.8.0) of Nidek's RS-3000 Advance system was used to analyze the spectral-domain optical coherence tomography and optical coherence tomography angiography images. RESULTS A total of 60 right eyes of 60 individuals were included in the study. Thirty subjects were in the athlete group, and 30 patients were in the nonathlete group. Sixteen of the individuals in the athlete group and 15 in the nonathlete group were women (P > .05). Retinal nerve fiber layer and ganglion cell complex thicknesses in all quadrants were thinner in nonathletes (P < .05). All of the Early Treatment Diabetic Retinopathy Study regions except central foveal subfield thickness were significantly higher in the athlete group (P < .05). In the nonathlete group, significantly reduced vessel densities of the superficial and deep capillary plexus and radial peripapillary capillary plexus, and the foveal avascular zone circularity index along with an increased foveal avascular zone perimeter and area were also detected (P < .05). CONCLUSIONS Our study revealed that optical coherence tomography angiography measurements may be used in the determination of the effects of physical activity on retinal vascular structure changes.

Abstract
Purpose: To evaluate the effects of a single dose of oral 5-mg tadalafil on macular microcirculation as measured using optical coherence tomography (OCT) and angiography (OCTA) in healthy volunteers. Methods: Twenty-two healthy, middle-aged, sexually active, and male health care worker volunteers were included in this prospective study. All volunteers have a history of occasionally using off-label 5 mg tadalafil to enhance sexual performance. Superficial and deep capillary plexus vascular densities, foveal avascular zone parameters, outer retina, and choriocapillaris flow areas were performed using the OCTA, and subfoveal-choroidal thickness (CT) was performed by using the OCT. Measurements were performed preintake, 30 min, 1, 4, 24 h, 2, 3, 4, and 7 days after the intake of tadalafil off-label. Results: Twenty-two eyes of 22 male volunteers were included in the study. The mean age was 37.16 ± 4.52 years. At 30 min, 1 h, and 4 h after intake, a statistically significant increase was observed in the choriocapillaris flow area and CT compared with preintake (Friedman test, P = 0.034 and P < 0.001, respectively). Conclusion: This study showed that a single dose of oral 5-mg tadalafil causes an increase in choriocapillaris flow and CT. To evaluate the effects of tadalafil on the retina and choroid, an OCTA assessment may be helpful.
