Goldmann and modified Goldmann tonometry measuring intraocular pressure changes in eyes which underwent myopic laser in situ Keratomileusis and photorefractive keratectomy.

Purpose: Compare intraocular pressure (IOP) measured by a standard Goldmann applanation tonometer prism (IOPg) and a modified correcting applanation tonometer surface Goldmann prism (IOPc) before and after laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK).

Methods: Goldmann tonometry was analyzed in a retrospective, cross-sectional study, using both GAT and modified-GAT prisms pre-operatively and at the 3 month post-operative appointment on 120 eyes (64 patients) who received LASIK (n = 58) or PRK (n = 62). Demographics, central corneal thickness (CCT), manifest refraction and corneal curvature (CC) data was collected at each visit as well as surgical parameters, including maximum ablation depth.

Comparing Surgical and Clinical Success Rates of Ahmed FP7, and Baerveldt 250 and Baerveldt 350 Glaucoma Drainage Devices.

Prcis: Surgical and clinical success rates were similar among Ahmed FP7, and Baerveldt 250 and 350 glaucoma drainage devices at three years.

Purpose: To compare rates of surgical and clinical success in patients with Ahmed FP7 (FP7), Baerveldt 250 (B250), or Baerveldt 350 (B350) glaucoma drainage devices (GDDs).

Design: A retrospective cohort study.

iSTAT (Intraluminal Suture Transfixed and Titratable) technique for ligature-free Reversal of long-term drainage implant hypotony.

Purpose: To describe the iSTAT (Intraluminal Suture Transfixed and Titratable) technique, an improvement on prior tube occlusion methods, allowing for variable flow.

Observations: A 76-year-old woman who underwent an uncomplicated glaucoma drainage device (GDD) placement for uncontrolled mixed mechanism glaucoma presented with hypotony 4 years post-operatively. The iSTAT technique was performed to adjust the flow in the GDD tube: a 4-0 polypropylene suture tip was blunted with a low-temperature cautery, creating a bulbed end that would occlude the tube.

Orbital anatomy magnetic resonance imaging in diplopic versus non-diplopic patients after glaucoma drainage device placement.

Purpose: New-onset persistent diplopia has become a common complication after glaucoma drainage device (GDD) placement. Understanding the orbital anatomy of such patients may provide information regarding risk of diplopia, GDD selection, and post-operative management. The purpose of this study was to examine the orbital anatomic differences in diplopic and non-diplopic patients after GDD implantation using high-resolution MRI.

Rates of Diplopia in Ahmed FP7, Baerveldt 250, and 350 Glaucoma Patients Compared With Medical Controls.

Precis: Diplopia was present in ~20% of patients with Ahmed FP7 (FP7) or Baerveldt 350 (B350), compared with 5% to 6% in those with Baerveldt 250 (B250) or controls, suggesting risk of diplopia should be included in preoperative counseling.

Purpose: The purpose of this study was to examine the prevalence of diplopia and strabismus in patients with B250, B350, or FP7 glaucoma drainage devices (GDD).

Materials And Methods: In this cohort study, glaucoma patients 18 years and above who had received, or would be receiving, a B250, B350, or FP7 GDD, and medically treated controls were consecutively enrolled from August 8, 2017, through July 31, 2019.

Health-related quality of life in Ahmed FP7, and Baerveldt 250 and 350 patients compared with medical controls.

Purpose: To compare health-related quality of life (HRQoL) in patients with Ahmed FP7 (FP7), Baerveldt 250 (B250) and Baerveldt 350 (B350) glaucoma drainage device (GDDs), and medically treated controls.

Methods: This was a prospective cohort study from August 2017 to July 2019. The NEI 25-Item Visual Function Questionnaire (VFQ-25), the Adult Strabismus-20 questionnaire (AS-20) and the Diplopia Questionnaire were conducted ≥30 days postoperatively in GDD patients, on enrolment for controls.

Etiology of Papilledema in Patients in the Eye Clinic Setting.

Importance: The study of health conditions associated with papilledema will augment the clinical judgment of eye care professionals treating patients with optic disc edema in determining the urgency of additional evaluation and counseling patients accordingly.

Objectives: To determine the incidence, demographic characteristics, and etiologies of papilledema based on a unique records-linkage research platform; and to describe the demographic and clinical differences between patients with idiopathic intracranial hypertension (IIH) and other causes of papilledema.

Design, Setting, And Participants: Retrospective population-based cross-sectional study of patients treated for papilledema at outpatient eye clinics in Olmsted County, Minnesota, using the Rochester Epidemiology Project.

Population-Based Evaluation of Lumbar Puncture Opening Pressures.

Prior studies evaluating opening pressure (OP) have mostly involved lumbar puncture (LP) for diagnosis of neurologic disease or small cohorts of healthy volunteers and therefore the normal OP is not well-defined. The goal of this study was to establish the normal range of OP in a community-based population using the Mayo Clinic Study of Aging (MCSA) and to evaluate factors that contribute to OP variability. LP OP were obtained from participants aged 32-95 years between 11/1/07 and 10/1/17, as part of routine data collection for the MCSA, a longitudinal, population-based study of residents of Olmsted County, Minnesota.

Variability of Consecutive Lumbar Puncture Opening Pressures.

Background: Lumbar puncture (LP) opening pressures (OPs) are known to fluctuate based on diurnal, environmental, and pathologic conditions. Despite their dynamic nature, single OPs are often deemed sufficient for diagnosis of elevated intracranial pressures (ICPs) in nonspecialists' hands. The purpose of this study was to determine the variability of consecutive LP OPs at a large referral center to determine the potential range of variability for a given LP OP.

A Population-Based, Case-Control Evaluation of the Association Between Hormonal Contraceptives and Idiopathic Intracranial Hypertension.

Purpose: To determine if the use of oral contraceptive pills (OCP) and other hormonal contraceptives are associated with a higher incidence of idiopathic intracranial hypertension (IIH).

Design: Retrospective, population-based, case-control study.

Methods: Setting: Female IIH patients evaluated between January 1, 1990, and December 31, 2016 were identified using the Rochester Epidemiology Project (REP), a record-linkage system of medical records for all patient-physician encounters among Olmsted County, Minnesota, residents.

Re-evaluating the Incidence of Idiopathic Intracranial Hypertension in an Era of Increasing Obesity.

Purpose: To re-evaluate the population-based incidence of idiopathic intracranial hypertension (IIH) and to determine if it mirrors the rise in obesity.

Design: Retrospective, population-based cohort.

Participants: All residents of Olmsted County, Minnesota, diagnosed with IIH between January 1, 1990, and December 31, 2014.

Surgical correction of childhood intermittent exotropia and the risk of developing mental illness.

Purpose: To assess whether successful surgical intervention for intermittent exotropia, or the timing of intervention, has any effect on the development of mental illness.

Design: Retrospective, observational case series.

Methods: All patients (<19 years of age) diagnosed with intermittent exotropia in Olmsted County, Minnesota, from January 1, 1975, through December 31, 1994, were reviewed retrospectively.
