Angle closure glaucoma is a major cause of blindness worldwide, with a high prevalence in Asian populations. Pupillary block is the principal mechanism in primary angle closure leading to impaired aqueous outflow, raised intraocular pressure, and glaucomatous optic neuropathy. Laser plays a major role in the management of primary angle closure in its prevention and treatment of the disease.
Asparagus urine. Some people have "hitchhiker's thumbs," which bend backwards with a large angle between the two segments phalanges. The myth is that there are just two kinds of thumbs, straight thumbs S and hitchhiker's thumbs Hand the trait is controlled by a single gene with two alleles, with the allele for S being dominant.
In a video of the private meeting, Angle defends a series of campaign ads that lean on images of dark-skinned men. Some of you look a little more Asian to me. My grandchildren are evidence of that.
Previous estimates of PACG were based largely on early studies, mostly using inappropriate case definitions. Therefore, we did a systematic review and meta-analysis to estimate the prevalence of PACG in adult Asian populations and to quantify its association with age, gender, and region. All primary reports of population-based studies that reported the prevalence of PACG in adult Asian populations were identified.
Purpose: To compare the ultrasound biomicroscopic measurement of the anterior chamber angle in Asian Indian eyes, with the angle width estimated by gonioscopy. Materials and Methods: Participants: Patients with open and closed angles attending a glaucoma clinic were recruited for the study. Observation Procedures: Temporal quadrants of the angles of patients were categorized by gonioscopy as Grade 0 to Grade 4, using Shaffer's classification.
Table 1. NOTE: The studies reporting prevalence used different definitions of disease; therefore, caution should be exercised when comparing these studies. Primary Open-Angle Glaucoma.
Create a signal that consists of two sinusoids of frequencies 15 Hz and 40 Hz. Sample the signal at Hz for one second. Compute the Fourier transform of the signal.
We obtained standardized digital slit-lamp iris photographs and graded the iris crypts by number and sizefurrows by number and circumferential extentand color higher grade denoting darker iris. Vertical and horizontal cross-sections of anterior chamber were imaged using anterior segment optical coherence tomography. Associations of the angle width with the iris surface features in the subject's right eyes were assessed using linear regression analysis.
Abstract: Glaucoma is a group of heterogeneous optic neuropathy and is the second leading cause of irreversible blindness worldwide. PACG is characterized by the closure of angles between iris and trabecular meshwork iridocorneal angles mainly because of anatomic abnormalities. The condition is more prevalent in Chinese, Asian Indians, and Eskimos.
