Brief Summary

Long term Surgical Outcomes of Viscotrabeculotomy in Pediatric Glaucoma Following Cataract Surgery. Purpose: This study aims to compare outcomes of single-site rigid probe viscotrabeculotomy (VT) to two-site VT in pediatric secondary glaucoma following cataract surgery. Methods: This is a comparative study was performed on patients aged ≤ 12 years and required surgery for glaucoma following congenital cataract surgery (GFCS) with or without intraocular lens (IOL) implantation. Eyes in which the trabeculotomy involves \<180° of Schlemm's canal ,eyes that have synechial angle closure over ≥ 90° and eyes that have previous procedures other than lensectomy or IOL implantation are excluded from the study. Eyes are then randomized to undergo single-site VT or two-site VT using a random table. The two-site VT by the rigid probe trabeculotome is performed through a superonasal and an inferotemporal triangular scleral flap. Intraocular pressure (IOP), anti-glaucoma medications, complications and success rates at dates of follow up are all reported. Success is defined as IOP between 6-20 mmHg or 35% IOP reduction with or without topical anti-glaucoma medications and without visually-devastating complications or additional glaucoma surgery.

Outcome Measures

Primary Outcomes (1)

  • the success rate in lowering IOP

    Success is defined as IOP between 6-20 mmHg or 35% IOP reduction with or without topical anti-glaucoma medications and without visually-devastating complications or additional glaucoma surgery. IOP was evaluted during each Follow up visit using applanation tonometry.

    3 years

Secondary Outcomes (6)

  • Intraocular pressure (IOP) control values

    3 years

  • antiglaucoma medications.

    3 years

  • postoperative complications

    3 years

  • horizontal corneal diameter.

    3 years

  • axial length.
