The Effect of Tamsulosin on Iris Morphology, Ciliary Muscle Thickness, and Pupil Diameter.
Am J Ophthalmol
December 2024
Department of Urology (M.E.), Assoc. Prof. M.D., Hitit University Erol Olçok Education and Research Hospital, Çorum, Turkey.
Purpose: To investigate the effect of tamsulosin on iris morphology, ciliary muscle thickness (CMT), pupil diameter (PD), and pupil responses to light using anterior segment optical coherence tomography and corneal topography.
Design: Prospective clinical before-and-after study METHODS: The right eyes of 43 patients with newly diagnosed benign prostatic hyperplasia were included in this study. Iris dilator muscle region (DMR) thickness, sphincter muscle region (SMR) thickness, DMR/SMR ratio, PD (scotopic, mesopic and photopic light conditions), CMT1 (1 mm posterior to the scleral spur), CMT2 (2 mm posterior to the scleral spur), CMT3 (3 mm posterior to the scleral spur) and anterior chamber depth (ACD) were measured before and after dilation.
Floppy iris. How is floppy iris syndrome managed? What do urologists and ophthalmologists say?
Rom J Ophthalmol

Dr. Stănilă Medical Centre, Ofta Total Clinic, "Lucian Blaga" University of Sibiu, Romania.
Article Synopsis
- The study investigates how chronic treatment with tamsulosin, used for benign prostatic hyperplasia (BPH), impacts the eye during cataract surgery, particularly focusing on Intraoperative Floppy Iris Syndrome (IFIS).
- It involved 100 male patients, with 24 using BPH medication, revealing that mydriasis management was necessary in many cases, and some complications arose during surgery, like iris damage.
- The findings suggest that stopping tamsulosin shortly before surgery may not prevent IFIS, indicating that patients who may develop cataracts should consult an ophthalmologist early on.
Alpha-adrenergic antagonists and iris dynamics: Challenges and solutions in cataract surgery.
BMC Ophthalmol
October 2024
Department of Ophthalmology, Military Hospital, Bathinda, India.
Background: Alpha-1 adrenergic receptor antagonists (α1-ARAs) are frequently used in treatment of Hypertension and symptomatic benign prostatic hypertrophy (BPH). Numerous studies have demonstrated the association between α1-ARAs like Tamsulosin and increased surgical risks for patients undergoing cataract surgery. This study aims to identify and study the effects of α1-ARAs on iris parameters and the subsequent operative challenges encountered during cataract surgery.

Indian J Med Res
October 2024
Nayan Eye Centre & Med Invent Devices Pvt. Ltd., Kolkata, India.
Article Synopsis
- Some people need cataract surgery, but some have small pupils that won't dilate, which can make surgery harder and riskier.
- A new device called the B-HEX Pupil Expander was invented to help with this problem and is easier and safer than older devices.
- Even though the B-HEX is popular in India and has support from experts, it's not available everywhere because of strict rules and lack of resources.
