Erectile Dysfunction Following Radical Prostatectomy
Conditions
Brief summary
This study evaluates the retinal and choriocapillary vascular features in patients under the effects of Tadalafil 20mg for more than 6 months, using optical coherence tomography angiography.
Detailed description
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 noninvasive 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 features after the somministration of Tadalafil 20 mg orally for more than 6 months.
