Abstract Details

Purpose:

To study the effectiveness of laser reconstruction of the zone of non-penetrating deep sclerectomy when it is blocked by the root of the iris.

Setting:

The S. Fedorov Eye Microsurgery State Institution

Methods:

The study was based on the analysis of 95 cases (95 patients) of the iris touch to trabeculo-descemet’s membrane. 65 patients (65 eyes), with the blockade of the iris root of the iris after NPDS and 30 patients (30 eyes), whose iris root contact with trabeculo-descemet’s membrane was diagnosed after laser descemetogoniopuncture. The level of IOP at the time of diagnosis of the blockade of the NPDS zone averaged 27.04±5.20 mmHg. All patients underwent laser reconstruction of the surgical zone, which included laser gonioplasty, iridectomy and, if possible DGP.

Results:

In 27 cases with blockade after NPDS was not completely eliminated. On the first day after laser surgery, IOP decreased to an average of 17.34±3.50 mmHg. The hyphema was observed in 3 cases. In the eyes after DGP IOP had an average pressure of 18.65±4.65 mmHg., the hyphema was observed in 2 cases. It was possible to remove the blockade of the operation zone in the 21 cases.

Conclusions:

One of the main predisposing factors to the onset of blockade of the zone of non-penetrating deep sclerectomy is the intraoperative perforation of the trabeculo-Descemet’s membrane and the perforation of the trabeculo-Descemet’s membrane during laser DGP.
