Abstract Details

Purpose:

To compare the results of membranectomy for the management of visual axis opacification (VAO) using either the anterior (limbal) or posterior (pars plana) approach in pediatric patients.

Setting:

Dr. Rajendra Prasad Centre for Ophthalmic Sciences, AIIMS

Methods:

50 patient were recruited and randomly divided into two group Group A and Group B. Group A underwent membranectomy by anterior approach and Group B underwent membranectomy using 23G pars plana approach, wherein the vitrectomy cutter was introduced through para plana route while the irrigation was mainatained through limbal port. All the eyes were left sutureless in both groups. IOL stability, ease of doing membranectomy, change in keratometry (steepest and flattest axis), media clarity and change in intraocular pressure were then compared between the two groups at 6 weeks duration at the time of EUA (Examination under Anesthesia).

Results:

No significant difference could be obtained between the two groups with respect to change in steepest or flattest keratometric values, intraocular pressure and media clarity post-operatively. IOL manipulation was lesser with pars plana route as most of the times, VAO was behind the IOL. None of the patients in any groups developed intraocular infection.

Conclusions:

The two methods are similar with respect to success rate, corneal astigmatism and effect on intraocular pressure. However, posterior approach was a surgically easier approach without the risk of IOL decentering while clearing the visual axis. It may be safe to leave the eyes which undergo pars plana membranectomy sutureless.
