Abstract Details

Purpose:

To demonstrate a simple technique that helps proper application of diode laser applications on the surface of the eye to treat refractory glaucomas.

Setting:

Kasr Aini School of Medicine, Cairo University, Egypt.

Methods:

In this technique, Osher-Neumann Stainless 16 blades Radial Marker is used to mark the corneal surface and extend the marks across the limbus to the peripheral sclera. The 2 horizontal marks nasally and temporally delineate the areas that we should avoid laser applications during treatment. Two laser treatments are applied along each of the remaining 12 marks ( 24 applications). One laser treatment is adjacent to the limbus and another one 1 mm behind the limbus. The laser settings are 15 mW and 3000 ms. The photos will show the technique in detail.

Results:

Using this technique it was possible to : 1- properly delineate the 3 and 9 clock meridia where no laser should be applied. 2- place the laser burns homogenously around the limbus.

Conclusions:

Diode trans-scleral cyclophotocoagulation to lower the intraocular pressure in refractory glaucomas is a blind procedure. The presented technique helped homogenous application of the laser burns. Further studies are required to compare with the random applications regarding the safety and efficacy.
