Abstract Details

Purpose:

To evaluate the outcome of pars plana vitreous aspiration during combined trabeculectomy, phacoemulsification and IOL implantation in eyes with shallow anterior chamber to prevent its associated complications.

Setting:

Difficult very shallow AC eyes in need for combined Trabeculectomy and phacoemulsification with IOL implantation.

Methods:

54 eyes of 46 patients were included in this study. All eyes were indicated for combined trabeculectomy, phacoemulsification and IOL implantation. All eyes had very shallow anterior chamber and injection of a viscoelastic substance through anterior chamber paracentesis failed to deepen the anterior chamber. Vitreous aspiration was performed with a 23-gauge needle on a 3-ml syringe over the pars plana 3.5 mm posterior to the limbus in the superotemporal quadrant. All cases were followed up for 3 to 6 months. Main outcome measures were volume of aspirated vitreous, intraoperative and postoperative complications.

Results:

Intraoperative deepening of anterior chamber occurred in all cases after vitreous aspiration. Aspirated vitreous volume varied from 0.3 to 1.5 ml, averaging 1.0 ml. No case had evidence of positive vitreous pressure during surgery. No intraoperative complications occurred in all cases. Postoperative complications were detected in the form of shallow AC with hypotony in 5.5% of cases ( 3 out of 54 cases) and Shallow AC with high IOP in 3.7% of cases (2 out of 54 cases) all cases were managed without need for second surgery. Complications related to vitreous aspiration like vitreous haemorrhage, retinal tear or detatchment. Were not observed in any case.

Conclusions:

Pars plana vitreous aspiration is a safe procedure to prevent intraoperatine shallow AC and its associated complications during combined trabeulectomy, phacoemulsification and IOL implantation.
