Abstract Details

Purpose:

The aims of the present study were, first investigate the differences in anterior chamber configuration between patients using alpha adrenerjic blocker drugs and healty volenteers.and second to develop a new method for predicting intraoperative floopy iris syndrome prior to surgery by using those changes.

Setting:

In a single institution, prospective randomized controlled trial

Methods:

Thirty-two patients who have used doxazosin per daily and thirty healty volunteers were included in our study.All eyes were assesed with AS-OCT to detect ACD, IRC, iris thickness (IT750, IT2000), pupil diameter. Outcome measures were compared between two groups and statistical results assesed to develop a scoring method for predicting IFIS. The patients in study group assessed for each statistically significant factor with point 0 to 1 according to the patient's value and average of study group.The patients with three or more points considered as a risky group for development of IFIS peroparatively.

Results:

ACD values in study and control groups were 3.65 ± 0.13 mm and 3.62 ± 0.10 mm, respectively. (p=0,23) The mean values of undilated pupil were 3,2±0,7 mm in study group and 3,3±0,8 mm in control group.(p=0,532). However there was a statistically significant difference between dilated pupil diameter measurments.between groups.( 8,7±1,4 mm, 11,5±1,8 mm respectively)(p<0,01). IT750, IT2000 and IC values analyzed by AS-OCT significantly different between groups.(p<0,01, p<0,001, p<0,01) A statistically significant difference between dilated pupil diameter, IT750, IT2000 and IC. IFIS was seen in 9 patients (28.1%) in the study group and in 1 (3,1%) patient in control group.

Conclusions:

Surgeons may prevent many complications by the prediction of IFIS prior to surgery. This was made possible by improving our original scoring system. However, confirmation by larger prospective randomised studies is needed
