National Utilization of Glaucoma Laser and Surgical Management in Medicare Beneficiaries: Disparities and Accessibility.

Prcis: In this population-based, cross-sectional study of Medicare beneficiaries, there were lower odds of national glaucoma surgery among ages older than 85, female sex, Hispanic ethnicity, and diabetic comorbidity. Glaucoma surgery rates were independent of ophthalmologist distribution.

Purpose: With an increasing prevalence of glaucoma in the United States, it is crucial to elucidate surgical procedure accessibility to deliver quality care.

Iridoschisis: visual outcome in treated versus untreated eye.

A 67-year-old man was referred for iris color change. He was noted to have narrow angles with atrophic iris appearance and visually significant cataracts. The iris findings were consistent with iridoschisis.

Complication of an Ahmed glaucoma valve implant: tube exposure with methicillin-resistant Staphylococcus aureus infection.

Neovascular glaucoma is commonly treated surgically with implantation of glaucoma drainage devices. We report the case of a 57-year-old man who underwent an uneventful Ahmed glaucoma valve (AGV) placement for radiation-induced neovascular glaucoma but later developed early postoperative infection with tube exposure. The infection was identified 3 weeks postoperatively and antibiotic treatment was immediately initiated.

Psychomotor vigilance and visual field test performance.

Introduction: Visual field test is an invaluable tool to evaluate the detection and progression of glaucoma. On the other hand, as a subjective test, reliable results depend on patients' optimum performance including vigilance during the test. The purpose of this study was to understand patient's attitude and preferences about the visual field test taking, and in addition to assess the relationship between the reliability indices of visual field testing (VFT) and the Walter Reed Psychomotor Vigilance Test (PVT).

The effect of mydriatic solutions on cognitive function.

Introduction: Anticholinergic and sympathomimetic ophthalmic solutions are used for mydriasis. These solutions have well-documented systemic side effects despite their topical administration. However, no studies have been conducted regarding the effect of mydriatic drops on cognitive function.

Optic disc and visual test findings in patients with migraine.

This study was conducted to determine whether the optic disc appearance and the visual field parameters of patients with migraine vary from those of age-matched controls. Twenty-two patients with migraine and 20 control participants were enrolled in the study. The automated visual field tests by Humphrey Field Analyzer® and optic disc images by Topcon® fundus camera were obtained from each participant.
