Hypotony Failure Criteria in Glaucoma Surgical Studies and Their Influence on Surgery Success.

Purpose: Review hypotony failure criteria used in glaucoma surgical outcome studies and evaluate their impact on success rates.

Design: Systematic literature review and application of hypotony failure criteria to 2 retrospective cohorts.

Participants: A total of 934 eyes and 1765 eyes undergoing trabeculectomy and deep sclerectomy (DS) with a median follow-up of 41.

Long-Term Visual Field Outcomes After Ahmed Glaucoma Valve Implantation.

Purpose: To measure visual field (VF) rates of change after Ahmed Glaucoma Valve (AGV) implantation and to investigate risk factors for progression.

Design: Retrospective, clinical cohort study.

Methods: Patients who underwent AGV implantation with at least 4 eligible postoperative VFs and 2 years of follow-up were included.

Subconjunctival Injections of Mitomycin C Are Associated with a Lower Incidence of Hypertensive Phase in Eyes with Ahmed Glaucoma Valve.

Purpose: To evaluate the association of intraoperative and postoperative subconjunctival injections of mitomycin C (MMC) and rate of the hypertensive phase after implantation of the Ahmed glaucoma valve (AGV).

Design: Comparative case series.

Participants: This retrospective comparative study included 37 eyes of 35 patients with uncontrolled glaucoma on maximum tolerated medical therapy who underwent implantation of AGV by a single surgeon.

Evidence of autophagic vesicles in a patient with Lisch corneal dystrophy.

Lisch corneal dystrophy is a rare corneal disease characterized by the distinctive feature of highly vacuolated cells. Although this feature is important, the nature of these vacuoles within corneal cells remains unknown. Here, we sought to analyze corneal cells from a patient diagnosed with Lisch dystrophy to characterize the vacuoles within these cells.
