Abstract

Purpose: To study the prevalence of Intraoperative Floppy Iris Syndrome(IFIS) in patients on Tamsulosin using the “Baseball Bat” sign using Anterior Segment OCT(AS-OCT)

Methods: This retrospective study was carried out at a single centre over a period of 3 years. 54 patients on Tamsulosin, scheduled for Cataract Surgery underwent preoperative AS-OCT. Iris pattern of these patients were studies & clinically correlated it with the occurrence of IFIS

Results: Significant thinning of the Dilatory Muscle Region (DMR) of the iris was noted, giving it a resemblance akin to a “Baseball Bat”. 85.18%(46 of 54)of these patients demonstrated a positive sign. 95.65%(44 of 46)of patients with a positive sign showed signs of IFIS, denoting a strong correlation(p<0.05%). None of the 8 patients with negative sign showed characteristics of IFIS Conclusions: “Baseball Bat” sign can be effectively used as a marker to predict IFIS in patients on Tamsulosin &amp;intraop measures can be taken to prevent the same

”Baseball Bat“ sign:-Predicting prevalence of Intraop Floppy Iris Syndrome in Patients on Tamsulosin

Purpose:

To study the prevalence of Intraoperative Floppy Iris Syndrome(IFIS) in patients on Tamsulosin using the “Baseball Bat” sign using Anterior Segment OCT(AS-OCT)

Methods:

This retrospective study was carried out at a single centre over a period of 3 years. 54 patients on Tamsulosin, scheduled for Cataract Surgery underwent preoperative AS-OCT. Iris pattern of these patients were studies & clinically correlated it with the occurrence of IFIS

Results:

Significant thinning of the Dilatory Muscle Region (DMR) of the iris was noted, giving it a resemblance akin to a “Baseball Bat”. 85.18%(46 of 54)of these patients demonstrated a positive sign. 95.65%(44 of 46)of patients with a positive sign showed signs of IFIS, denoting a strong correlation(p<0.05%). None of the 8 patients with negative sign showed characteristics of IFIS

Conclusions:

“Baseball Bat” sign can be effectively used as a marker to predict IFIS in patients on Tamsulosin &intraop measures can be taken to prevent the same
