Do common prostate drugs change the eye? a trial investigates
NCT ID NCT07743060
First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time
Summary
This study compares two common prostate medications, tamsulosin and silodosin, to see how they affect pupil size and the thickness of a layer at the back of the eye called the choroid. Men aged 50 and older with benign prostatic hyperplasia (BPH) who have not used these drugs before will take one of the two medications daily for three months. Researchers will measure pupil size under different lighting conditions and choroidal thickness before and after treatment. The goal is to understand if these drugs cause eye changes that could increase risks during cataract surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- tamsulosin 0.4 mg daily or silodosin 8 mg daily
- What this could lead to
- If this trial shows one drug has less effect on the eye, it could help guide safer choices for men with BPH who may need cataract surgery later.
- What could go wrong
- This is a small, early-stage comparison. The results may not apply to all patients, and the study only looks at eye changes, not long-term safety or cataract surgery outcomes.
