Surgical treatment: New filtering procedures
Comment by Paul Palmberg on:
13937 A novel approach to suprachoroidal drainage for the surgical treatment of intractable glaucoma, Jordan JF; Engels BF; Dinslage S et al., Journal of Glaucoma, 2006; 15: 200-205
Jordan et al. (602) tell of their results with an ingenious internal filtering procedure that uses a silicone tube, implanted in the bed of a half-thickness scleral flap, that is passed forward through an intrascleral channel to connect to the anterior chamber and also backward under a posteriorly-hinged flap in the floor of the scleral bed to connect to the suprachoroidal space. In 31 patients, the IOP was reduced from 44 to 13 mmHg in the successful (70%) eyes at 30 weeks. The success rate fell off sharply, however, with 60% success at 52 weeks and 40% at 76 weeks, and a mean time to failure of 56 weeks. Nevertheless, in eyes that have had multiple previous failures, the result was encouraging. One would love to know how this procedure would compare to a glaucoma drainage device in such eyes.
