Abstract Details

Purpose:

To evaluate preoperative pupillographic parameters 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.

Results:

The study included 79 patients,11 low grade IFIS, 14 moderate IFIS, 29 severe IFIS patients and 25 control. Scotopic/mesopic/photopic pupil diameter was 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 respectively in low IFIS, moderate IFIS, severe IFIS and control groups. No statistically significant differences were observed between groups (p�â�‰�¥0,05). In subgroup analysis, there was statistically significant difference between control and severe IFIS in scotopic and mesopic pupil diameters(respectively p:0,044; p:0,040).

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 have shown that preoperative pupillography could be a predict�Ä�±ve method for IFIS. The severity of IFIS could be correlated with miosis and low range changes in pupil diameter with different light conditions. Especially pupil diameter is increased in IFIS under mesopic and scotopic conditions. Large scaled studies needed for certain results
