False negative results in glaucoma detection with Heidelberg Retina Tomograph II.

Purpose: To evaluate the rate of false negative results with the Heidelberg Retina Tomograph (HRT II) in a glaucoma practice.

Design: Cross-sectional study.

Methods: We analyzed the HRTs taken between October 2002 and October 2003 in our glaucoma clinic, and selected the patients who had a good quality image (SD < 40 mu) with a normal Moorfield's Regression Analysis (MRA).

Non-penetrating deep sclerectomy without or with autologous scleral implant in open-angle glaucoma: medium-term results.

Background: This study compares the medium-term success rate and complications of non-penetrating deep sclerectomy (NPDS) without and with autologous scleral implant in open-angle glaucoma.

Methods: Retrospective review of 93 eyes of 93 patients with medically uncontrolled open-angle glaucoma who underwent NPDS without (n=69, group 1) or with (n=24, group 2) autologous scleral implant.

Results: The mean follow-up was 16 months (range 5-36) in group 1 and 15 months (range 4-28) in group 2.
