Abstract Details

Purpose:

The aim of the study was the assessment of efficacy and safety of compression sutures in patients with overfiltrative hypotony after glaucoma surgery.

Setting:

This study analyses the clinical outcomes of conjunctival compression sutures for 17 patients with ocular hypotony in Department of Diagnostics and Microsurgery of Glaucoma, Medical University, Lublin, Poland

Methods:

Only patients with hyperfiltration hypotony defined as intraocular pressure (IOP)≥ 6mmHg associated with a reduced vision aquity were included. Mean age of patients was 60,5±20,5. The main diagnosis was POAG in 9 cases; PSG in 3; PEXG in 4; ; traumatic glaucoma in 1. Primary procedure was trabeculectomy in 9; phacotrabeculectomy in 4; revision in 3 cases and deep sclerectomy in 1 case. In 13 patients maculopathy decreasing visual acuity was observed and in 4 choroidal detachments were present. The compressive Nylon 10-0 single sutures were performed in all patients; in 2 patients the procedure was repeated.

Results:

Mean intraocular pressure before suturing was 2,3±1,57mmHg and increased to 14,2±7,03mmHg(p=0,00065) in 7 days after and to 11,5±5,4mmHg(p=0,0022) in 3 months. After 6 months mean IOP was 10,2±4,3mmHg(p=0,005), after one year 9±4,7mmHg (p=0,0117). To obtain the target pressure 1 patient needed the sutures to be released and in 3 patients medical therapy was entered. Mean best corrected visual acuity before the sutures was 0,18±0,13 and increased to 0,53±0,25 (p=0,0004) in 3 months; after 6 months 0,46±0,31 (p=0,005), after one year 0,31±0,22 (p=0,025). In 1 case after the procedure the leakage from the bleb was observed which needed resuturing.

Conclusions:

The transconjuctival compression sutures placement seems to be efficient and safe technique for managing with ocular hypotony after glaucoma surgery .
