Comparison of the Intraocular Pressure Variation Provoked by Postural Change and by the Water Drinking Test in Primary Open-angle Glaucoma and Normal Patients

Journal of Glaucoma - Mon, 10/31/2016 - 11:00pm
Conclusions: POAG eyes demonstrated a significant IOP increase when assuming the supine position and during the WDT. The IOP increase during the WDT was significantly higher than the IOP increase after postural test. Hence, the results of both tests are not interchangeable. (Source: Journal of Glaucoma)

How Often the Goldmann Applanation Tonometer Should be Checked for Calibration Error?

Journal of Glaucoma - Mon, 10/31/2016 - 11:00pm
Purpose: To evaluate the frequency of Goldmann applanation tonometer (GAT) calibration error (CE) check. Methods: One observer at each of the 3 tertiary care ophthalmic centers was involved. The tonometers were checked at baseline for CE. A tonometer was defined as faulty when CE exceeded 2 mm Hg at any testing level. Faulty GATs were repaired in-house. Subsequent CE check was done once per month for 6 months. GATs were divided into 3 groups: group 1 (G1)≤1 year, group 2 (G2)>1 to 10 years, and group 3 (G3)>10 years of usage. Results: In total, 76 slit-lamp mounted GATs were included. The number of GATs in groups 1 to 3 was 19, 36, and 21, respectively. Seven (9.2%) tonometers were faulty at the baseline. None in G1, 5 in G2, and 16 in G3 demonstrated unacceptable CE over the study cou...

Optic Disc Characteristics and Visual Field Progression in Normal Tension Glaucoma Patients With Tilted Optic Discs

Journal of Glaucoma - Mon, 10/31/2016 - 11:00pm
Conclusions: The greater optic disc tilt and torsion in NTG eyes with tilted optic disc were associated with focal LC defects, but not with VF progression. The focal LC defects were associated with VF progression. This study suggests that the focal LC defects in NTG patients with tilted optic disc may be an independent risk factor for glaucomatous VF progression, and the development of focal LC defects could be influenced by optic disc torsion or tilt.

Evaluation of a Trabecular Micro-Bypass Stent in Pseudophakic Patients With Open-Angle Glaucoma

Journal of Glaucoma - Mon, 10/31/2016 - 11:00pm
Purpose of the Study: The purpose of the study was to evaluate the safety and efficacy of the iStent Trabecular Micro-Bypass stent in pseudophakic patients with open-angle glaucoma. Methods: Retrospective, consecutive case series from October 2012 to May 2015 with no exclusion criteria. The series comprised 42 pseudophakic eyes with open-angle glaucoma that were implanted with 1 iStent. Data were collected preoperatively, and postoperative data were collected at 1 day, 1 week, 1, 3 and 6 months, 1 year, 18 months and 2 years. Data included intraocular pressure (IOP), number of glaucoma medications, the incidence of postoperative IOP pressure spikes ≥15 mm Hg at any timepoint, and the need for additional surgery. Results: The mean preoperative IOP was 20.26±6.00 mm Hg. At 1 year postop...
