Abstract Details
Purpose:
To evaluate the effectiveness of laser reconstruction of the NDSE zone in case of iris blockade.
Setting:
S.N. Fyodorov Eye Microsurgery Federal State Institution of the Russian Ministry of Health
Methods:
The investigation included 95 cases of NDSE zone blockade by the iris root. In 65 cases the trabeculo-Descemet membrane (TDM) was blocked by the iris after the NDSE surgery – this was the first group, in 30 cases (30 eyes) the blockade was observed after the laser descemetogoniopuncture (DGP) – this was the second group. An average IOP level in the moment of blockade was 27.04±5.20 mm Hg. The patients age was between 57 and 79 years old, 68.1±5.3 on average. All the patients undergone laser reconstruction of the surgical zone, including laser gonioplasty, iridectomy and if possible – DGP.
Results:
In the first group there was a partial blockade of the surgical zone in 40 cases (61.5%). In 25 cases (38.5%) no TDM could be visualized by the gonioscopy. In patients of the second group there was a partial contact in 21 cases (70%) and a full blockade – in 9 cases (30%). It was impossible to eliminate the blockade of NDSE zone in 27 cases (41.5%) in first group. The blockade was eliminated in 21 cases (70%) in second group. The IOP level decreased to 17.34±3.50 mm Hg in first group and 18.65±4.65 mm Hg in second group.
Conclusions:
Intraoperative perforation of TDM by NDSE or by laser DGP is one of the main predisposition factors for the NDSE zone blockade. The laser reconstruction of the NDSE zone by its blockade with the iris root is effective in 62.1% of cases. An OCT investigation of the NDSE zone by its blockade with the iris root allows to forecast the effectiveness of a laser reconstruction and to decrease the level of complications.
