Abstract Details

Purpose:

To compare preoperative and postoperative pupillography changes related with the grade of intraoperative floppy iris syndrome after uneventful phacoemulsification surgery

Setting:

Prospective, randomized trial

Methods:

Patients who undergo uneventful phacoemulsification surgery in Bal�Ä�±kesir University Ophthalmology Department were examined preoperatively with detailed ophthalmologic examination include systemic disease, drug use, visual acuity, intraocular pressure, slit-lamp examination, fundus examination and scotopic, mesopic, photopic pupillographic measurements recorded. Intraoperative cumulative dispersive energy, fluid parametrics, intraoperative complications and iris behaviour was evaluated. The diagnosis of IFIS was defined as one point for each iris billowing, progressive miosis and iris prolapsus after intraoperative iris behaviour scored. When one, two, three point was defines as low, moderate and severe grade IFIS respectively. The same examination procedure was repeated postoperatively include pupillografic measurements.

Results:

The study included 38 patients, comprising 7 low grade IFIS, 6 moderate IFIS, 12 severe IFIS patients and 13 control. Scotopic/mesopic/photopic pupil diameter was 9,00�Â�±1,41; 9,33�Â�±2,58; 8,92�Â�±2,15; 10,15�Â�±1,34/ 8,71�Â�±1,38; 8,17�Â�±1,60; 7,83�Â�± 1,58; 8,85�Â�±0,80 / 6,86�Â�±1,21; 6,17�Â�±1,60; 6,42�Â�±1,31 7,23 �Â�±1,36 preoperatively and 9,00�Â�±2,30; 8,67�Â�±0,51; 8,67�Â�±1,61; 9,92�Â�±1,65/7,86�Â�±2,34; 7,67�Â�±0,81; 7,67�Â�±1,43; 8,77�Â�±1,48 /6,71�Â�±1,70; 6,50�Â�±0,83; 6,50�Â�±1,08; 6,77�Â�± 1,53 postoperatively; respectively in low, moderate, severe IFIS and control (p�â�‰�¥0,05). No statistically significant differences were observed between groups in pupil diameter changes (p�â�‰�¥0,05).

Conclusions:

In conclusion, Intraoperative floppy iris syndrome is a finely described clinical feature. The diagnosis of this syndrome has importance for the prediction of intraoperative complications. We hypotised that pupil diameter changes are more oftenly occur in IFIS patients but that was not supported by results. Especially pupil diameter is increased in IFIS under mesopic and scotopic conditions. Large scaled studies needed for certain results
