Anterior segment optical coherence tomography characteristics in an Asian population.

PURPOSE: To quantify the angle characteristics in an Indian population, and determine the prevalence of eyes at risk of angle closure. MATERIALS AND METHODS: This population-based cohort study was carried out to evaluate individuals, 40 to 59 years of age, clinically. The individuals underwent anterior segment optical coherence tomography of their right eyes in the horizontal meridian, using the enhanced protocol. RESULTS: The mean scleral spur angle for the population was 24.2±10.2 degrees, and a manually measured angle recess was 23.2±10.2 degrees, with a κ value of agreement of 0.78, 85.7

A population-based assessment of 24-hour intraocular pressure among subjects with primary open-angle glaucoma: the handan eye study.

PURPOSE: To describe the distribution of the 24-hour intraocular pressure (IOP) among subjects with primary open-angle glaucoma (POAG) in a population-based study in north China. METHODS: All untreated POAG patients (n = 66) identified in the Handan Eye Study were invited to attend a follow-up study in which IOP was tested with a Goldmann applanation tonometer at 10 AM, 2 PM, 6 PM, 10 PM, 2 AM, and 6 AM. RESULTS: Forty-seven subjects with untreated POAG (47/66; 71.2%) attended the study. Of them, 39 (83.0%) had a peak IOP ≤ 21 mm Hg. The peak IOP (mean ± SD) was 18.4 ± 3.7 mm Hg. Peak IOP oc

Comparative human aqueous dynamics study between black and white subjects with glaucoma.

PURPOSE: To compare the baseline aqueous humor dynamics in white Caucasians and patients of African origin with previously untreated primary open-angle glaucoma (POAG) or ocular hypertension (OHT). METHODS: Ninety-one participants were enrolled in this prospective, observational controlled study: 34 black subjects with POAG or OHT, 32 white Caucasian participants with POAG or OHT, and 12 black and 13 white healthy volunteers as the controls. All aqueous humor parameters were taken between 9 AM and 12 noon on the same day. Intraocular pressure (IOP) was measured by pneumatonometer; morning aqu

Long-term benefit of reduced intraocular pressure in primary open-angle glaucoma patients in Ethiopia.

PURPOSE: To determine the incidence of progression of primary open-angle glaucoma at individual levels of mean intraocular pressure (IOP) in patients in Ethiopia. METHODS: A retrospective, multicenter, cohort analysis of patient records with at least 5 years of potential follow-up were evaluated for risk factors associated with progressive optic disc and visual field loss. RESULTS: There were 300 patients with the potential of 5 years of follow-up. In total, 166 patients progressed before 5 years and 134 remained stable for the full 5-year follow-up period. Of the total sample, 84% of patien

Progressive venous stasis retinopathy and open-angle glaucoma associated with primary pulmonary hypertension.

A 40-year-old woman who had primary pulmonary hypertension presented with dilated episcleral vessels, venous stasis retinopathy, and open-angle glaucoma with reflux of blood in Schlemm's canal in both eyes. Intraocular pressure was controlled with anti-glaucoma medication along with systemic treatment of congestive heart failure. However, venous stasis retinopathy progressed with subsequent development of branch retinal vein occlusion in her right eye. The stagnation of venous blood flow and elevation of venous pressure found in individuals with primary pulmonary hypertension is responsible fo

Combined clear corneal phacoemulsification and ab interno trabeculectomy: three-year case series.

PURPOSE: To evaluate the efficacy and safety of a novel surgical approach, ab interno trabeculectomy, in a combined procedure (clear corneal phacoemulsification + ab interno trabeculectomy) for the management of concurrent cataract and glaucoma with prognostic factors for filtration failure. SETTING: Department of Ophthalmology, Palmanova Hospital, Udine, Italy. METHODS: A prospective noncomparative case series of 11 eyes of 11 consecutive cataract patients with medically uncontrolled primary open-angle glaucoma or pseudoexfoliation glaucoma was performed. Each patient had phacoemulsificatio

Drug-induced transient myopia and angle-closure glaucoma associated with supraciliary choroidal effusion.

PURPOSE: We investigated the mechanism of drug-induced transient myopia, anterior chamber shallowing, and secondary angle-closure glaucoma in a young woman. METHODS: Ultrasound biomicroscopy was performed and the effects of cycloplegic eyedrops and unilateral laser iridotomy were evaluated. RESULTS: Cycloplegic eyedrops and unilateral laser iridotomy had no effect. Ultrasound biomicroscopy identified the presence of a supraciliary choroidal effusion that caused forward displacement of the lens-iris diaphragm, resulting in increased myopia, anterior chamber shallowing, and angle-closure glauc

Intraocular pressure changes in nephropathia epidemica. A prospective study of 37 patients with acute systemic Puumala virus infection.

BACKGROUND: Nephropathia epidemica is a zoonose in the group of hemorrhagic fevers with renal syndrome and is caused by Puumala virus in Hantavirus genus. The purpose of this study is to find out how the intraocular pressure (IOP) is affected by the acute phase of this disease and how it relates to the previous case reports on angleclosure glaucoma attacks. PATIENTS AND METHODS: The prospective study documents IOP and anterior chamber depth measurements in 37 patients during the winter epidemic of nephropathia epidemica from 1992 to 1993. Ocular examinations were performed during the acute sy

Krukenberg's Spindle-Like Corneal Changes in a Patient With Prolonged ICU Admission: A Case Report.

Krukenberg's spindles are vertical, spindle-shaped pigment deposits on the posterior cornea and are primarily associated with pigment dispersion syndrome (PDS). We present a case of Krukenberg's spindle-like corneal changes in a 39-year-old male patient following prolonged ICU management for thyroid storm complicated by infective endocarditis. The patient's complex ICU course included mechanical ventilation, veno-arterial extracorporeal membrane oxygenation (VA-ECMO), and multiple medications. Ophthalmological examination revealed bilateral, brownish, linear changes in the central corneal stro

Central corneal thickness in a Jordanian population and its association with different types of Glaucoma: cross-sectional study.

BACKGROUND: Central corneal thickness (CCT) has long been implicated to affect glaucoma predisposition. Several reports have identified that thinner CCT is a risk factor for open-angle glaucoma, and that CCT can be very variable between different ethnic groups. In this study, we aim to identify the relation between CCT and different glaucoma parameters in different types of glaucoma in an Arabian ethnicity. METHODS: We classified our participants into four main groups: primary open-angle glaucoma (POAG), primary angle-closure glaucoma (PACG), pseudoexfoliative glaucoma (PXFG), and a control g
