To identify risk factors for central visual field progression in moderate to advanced glaucoma.

Purpose: To identify the risk factors for central visual field progression in moderate to advanced glaucoma.

Methods: We included patients with moderate to advanced primary glaucoma who had undergone at least five reliable Humphrey visual field (HVF) 10-2 tests with follow-up of at least 2 years. Regression slopes for each threshold location on the 10-2 plot were calculated.

To compare central visual field progression using mean deviation and pointwise linear regression analysis.

Purpose: To compare central visual field progression using mean deviation and pointwise linear regression (PLR) analysis.

Methods: We analyzed the 10-2 Humphrey visual field (HVF) tests for moderate and advanced primary glaucoma who had undergone at least five reliable 10-2 visual field tests with a minimum follow-up of at least two years and best-corrected visual acuity better than 6/12. Regression slope less than -1 dB/year at P < 0.

Effect of immediate shallow anterior chamber after Ahmed glaucoma valve implantation on intermediate-term intraocular pressure control.

Purpose: To evaluate the incidence of shallow anterior chamber in the early postoperative period following Ahmed glaucoma valve (AGV) implantation and its effect on the hypertensive phase (HP), intermediate-term intraocular pressure (IOP) control, and success rate.

Methods: A retrospective analysis of 369 eyes of 360 patients who underwent AGV implantation between January 2005 and January 2020 with a minimum follow-up of 2 months was performed. Twenty-six patients developed shallow anterior chamber (AC) within 8 weeks following surgery (cases).
