Abstract Details

Purpose:

To study long-term clinical results of refractory glaucoma surgery by using leucosapphire drainage system.

Setting:

S. Fyodorov Eye Microsurgery Federal State Institution Saint-Petersburg Branch, Russia.

Methods:

The device is made of leucosapphire as a pipe 2,6 mm length with inner diameter of 100 µm. Drainage implantation was done to 282 eyes of 282 patients at the age of 48-82 years (female – 172, male – 110). II glaucoma stage, 128 – III glaucoma stage, 154– IV glaucoma stage. Implantation has been executed after previously done unsuccessful operations. Trabeculectomy was performed for the similar control group. The mean intraocular pressure (IOP) before operation was 33,71±8,22 mm Hg in the main group and 33,31±6,48 mm Hg in the control group. The mean follow-up was 3,8±3,2 years.

Results:

Intraoperative complications have not been observed. During postoperative period hyperfiltration has been registered in 8cases (3,1%)?, choroidal detachment – in 12 (4,7%)?, hyphema – in 4 (1,6%)?. The most of these complications have been eliminated therapeutically. Satisfactory IOP control was obtained in all the eyes in a month after operation. However 12-36 month later IOP was normal in 63% of the eyes in the main group and in 58% of the eyes in the control group.

Conclusions:

Leucosapphire drainage implantation can be chosen from the other methods for the refractory glaucoma treatment. After implantation the postoperative period lasts unreactively because of absence of fibroblastic reaction in sclera to leucosapphire. According to our opinion satisfactory IOP control and long-term drainage function is achieved by unreactive material of the drainage.
