NCT04651231

Brief Summary

Bleb failure is reduced with Punch trabeculectomy procedure. Wide sclerostomy during surgery is wanted but controllable. This can be done with single securing suture, releasable sutures and topical intraoperative mitomycin-c. Average IOP without fluctuation (risk factor) can protect the optic nerve.

Conditions

Outcome Measures

Primary Outcomes (1)

  • postoperative intraocular pressure (IOP)

    measuring IOP at first day ,first month, three months, six months, nine months,and one year after surgery frequent interval in both groups with applanation method( Goldmann applanation tonometer

    one-year follow up

Secondary Outcomes (1)

  • bleb morphology after surgery

    one-year follow up

Study Arms (2)

tight flap technique group (forty patients-group A)

ACTIVE COMPARATOR

in this arm forty patients did tight flap technique for punch trabeculectomy. At 12 o'clock 10/0 nylon monofilament stitch was used to close the apex of triangular scleral flap tightly and two releasable stitches were used at the sides of triangular scleral flap.

Procedure: releasable sutures in punch trabeculectomy

loose flap technique (securing sutures) group (forty patients-group B).

EXPERIMENTAL

in this arm forty patients did loose flap technique for punch trabeculectomy. At 12 o'clock 10/0 nylon monofilament stitch was used to secure the edges of the flap at the apex of and two-four releasable stitches were used at the sides of triangular scleral flap in group B.

Procedure: releasable sutures in punch trabeculectomy

Interventions

punch trabeculectomy,scleral flap suturing

Also known as: loose flap technique versus tight flap technique in punch trabeculectomy
loose flap technique (securing sutures) group (forty patients-group B).tight flap technique group (forty patients-group A)
