Changes in Ocular Hypotensive Drug Usage for Glaucoma Treatment After Cataract Surgery: A Nationwide Population-based Study in Taiwan

Abstract

The aims of this study were to observe the changes in the demand for prescriptions of ocular hypertensive drug (OHD) after cataract surgery, to investigate patterns of change in the required OHD amount in open-angle glaucoma (OAG) and angle-closure glaucoma (ACG) cases, and to determine the associated factors related to the change. This population-based cohort study using the Taiwan National Health Insurance Research Database enrolled patients with glaucoma who underwent bilateral cataract surgeries within 2 years between 2001 and 2012. The major dependent variables were the total amounts of OHDs prescribed within 1 year before the first cataract surgery and 1 year after the second cataract surgery. We compared the overall change in the required OHD amount before and after cataract surgery and further explored potential factors affecting the change. Among the 440 patients, there were more cases of ACG than OAG (68.6% vs. 31.4%). The total OHD amount prescribed reduced significantly after cataract surgery in patients with OAG (median, from 12 to 6 bottles before and after the surgery, P<0.0001) and ACG (median, from 10 to 3 bottles, P<0.0001), and the reduction was sustained for 5 years. The reduction was significantly larger in...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.
