Glaucoma: Overview01:25

Glaucoma: Overview

1.4K
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...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.1K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

996
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.3K
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...

Multiple Comparison Tests01:13

Multiple Comparison Tests

4.5K
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

7.0K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Area of Science:

  • Ophthalmology
  • Medical Technology
  • Digital Health

Background:

  • Glaucoma is a leading cause of irreversible blindness worldwide.
  • Early detection and monitoring of visual field defects are crucial for managing glaucoma.
  • Traditional visual field perimetry requires specialized equipment and clinical settings.

Purpose of the Study:

  • To introduce a novel home-based visual field examination using accessible technology (PC monitors, VR glasses).
  • To evaluate the reliability of this home-based method by comparing it with the Humphrey perimeter.
  • To assess the potential of this method for internet-based glaucoma screening.

Main Methods:

  • A supra-threshold algorithm tested 52 points within the central 24° visual field at three intensity levels (-4, -8, -12 dB).
  • A web camera functioned as a virtual photometer for ambient light detection.
  • Self-testing was enabled via PC monitor or Android smartphone with VR glasses; an expert system analyzed results.

Main Results:

  • The home-based test demonstrated good receiver operating characteristic (ROC) curve performance, with area under the curve (AUC) ranging from 0.762 to 0.837 (P<0.001).
  • Sensitivity varied between 0.637 and 0.942, while specificity ranged from 0.735 to 0.497.
  • Results were compared point-by-point with Humphrey perimeter data from ten patients (20 eyes).

Conclusions:

  • The home-based visual field test shows comparable reliability to the Humphrey perimeter.
  • The method does not necessitate specialized or expensive equipment.
  • This accessible approach holds potential for effective glaucoma screening via the internet.
