Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

887
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Blinding

3.8K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Glaucoma: Overview01:25

Glaucoma: Overview

1.1K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Clinical Trials: Overview01:11

Clinical Trials: Overview

4.4K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Clinical Trials

10.1K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.0K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Summary
This summary is machine-generated.

Randomized controlled trials (RCTs) in ophthalmology are scarce, primarily focusing on retinal diseases and glaucoma. High-impact RCTs are often published outside specialized ophthalmology journals.

Area of Science:

  • Ophthalmology
  • Evidence-Based Medicine
  • Clinical Research

Background:

  • Randomized controlled trials (RCTs) are the gold standard for medical evidence.
  • Assessing the volume and quality of RCTs is crucial for evaluating evidence in a medical field.

Purpose of the Study:

  • To evaluate the current status and trends of RCTs within the field of ophthalmology.
  • To identify key subspecialties and journals publishing ophthalmology RCTs.

Main Methods:

  • A comprehensive PubMed search was conducted on May 15, 2019, for ophthalmology RCTs.
  • Results were categorized using the Medical Subject Heading (MeSH) system.
  • Altmetric explorer was used to identify high-impact journals and articles.

Main Results:

  • Only 2.15% of ophthalmology publications were RCTs (11,634 out of 540,427).
  • Retinal diseases, glaucoma, and conjunctival diseases had the most RCTs.
  • Most high-impact RCTs were published in non-ophthalmology journals, with only 18% in top 10 ophthalmology journals.

Conclusions:

  • Ophthalmology RCTs are concentrated in specific areas like retina and glaucoma, with less focus on sclera, orbit, and eyelids.
  • High-impact research is frequently published in general medical journals rather than ophthalmology-specific ones.
