A comprehensive ophthalmological evaluation including the near vision and the automated pupillometry was performed at baseline and after 3 months of silodosin treatment. For subjective assessment of near visual ability and satisfaction, a Near Activity Visual Questionnaire-10 (NAVQ-10) was also used at the same time (higher scores indicating worse quality).Results: Of 23 patients enrolled in this study, 15 continued with silodosin (8 mg once daily) treatment for 3 months and completed a follow-up evaluation. The mean age of participants was 60.4\u00b18.4 years. Distant visual acuity and spherical error were unchanged after silodosin treatment. However, near vision acuity (logMAR) was improved after treatment (right, 0.47\u00b10.36 vs. 0.38\u00b10.39, P=0.018; left, 0.41\u00b10.37 vs. 0.31\u00b10.34, P=0.068; both, 0.27\u00b10.26 vs. 0.21\u00b10.27, P=0.043). Pupil size under room light decreased significantly in both eyes (right, 3.77\u00b10.60 vs. 3.16\u00b10.58, P=0.001; left, 3.72\u00b10.80 vs. 3.21\u00b10.75, P=0.002). The Rasch scale at NAVQ-10 improved from 54.7\u00b19.9 to 48.5\u00b111.2 (P=0.004).Conclusions: This preliminary study demonstrated that highly selective alpha-1A adrenergic receptor antagonists such as silodosin improve near visual acuity and quality in patients with LUTS\/benign prostatic hyperplasia. Decrease in pupil size caused by inhibition of adrenergic alpha 1 mediated contraction of iris dilator muscle is a possible mechanism underlying improved near vision.<\/jats:p>","DOI":"10.5213\/inj.2040274.137","type":"journal-article","created":{"date-parts":[[2021,1,19]],"date-time":"2021-01-19T12:36:15Z","timestamp":1611059775000},"page":"164-171","update-policy":"https:\/\/doi.org\/10.5213\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Improvement
