简要总结
This study evaluates the retinal and choriocapillary vascular features in patients under the effects of Tadalafil 20mg using optical coherence tomography angiography.
详细描述
Tadalafil is a an inhibitor of the enzyme phosphodiesterase and it works by increasing blood flow to the penis thus promoting the erection.
This drug represents an treatment for erectile dysfunction in patients after radical prostatectomy.
The optical coherence tomography angiography represents a novel and non-invasive diagnostic technique that allows a detailed and quantitative analysis of retinal and choriocapillary vascular features.
The study evaluates the changes in optical coherence tomography angiography parameters at baseline and after 1, 3, 6 months after the somministration of Tadalafil 20 mg orally.
