Novel and Semiautomated 360-Degree Gonioscopic Anterior Chamber Angle Imaging in Under 60 Seconds.

Abstract

Obtaining slit-lamp gonioscopic images requires a high level of expertise and can be time consuming. The images typically are limited to 4 quadrants with limited resolution and can be affected by different lighting conditions. Our goal was to study the ability of the novel imaging system to quickly and easily document the full 360 degrees of the anterior chamber angle in a standardized manner. Cross-sectional cohort study. Eighty-four eyes from 50 subjects were included in this study, including 26 eyes from 17 normal participants and 58 eyes from 33 patients diagnosed with glaucoma. A newly introduced, commercially available gonioscope (GS-1, NIDEK Co, Gamagori, Japan) was utilized to perform semiautomated imaging of the full 360-degree iridocorneal angle on participants under an institutional review board-approved study. Topical proparacaine was administered to the eye to anesthetize the eye and imaging was completed using the 16-mirror, machine-attached gonioscopic lens coupled with lubricating ophthalmic gel ointment. The first step of the 2-step image acquisition process is analogous to manual gonioscopy, whereas the second step is performed by the instrument in an automated fashion. First, the instrument is manually moved ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
