Summary
Smartphone imaging offers a novel method for estimating the iridocorneal angle (ICA). This cost-effective technique shows excellent correlation with traditional methods, aiding in identifying angle-closure disease.
Area of Science:
- Ophthalmology
- Medical Imaging
- Biomedical Engineering
Background:
- Smartphone technology is advancing ophthalmic imaging capabilities.
- Accurate iridocorneal angle (ICA) measurement is crucial for diagnosing glaucoma and related conditions.
Purpose of the Study:
- To investigate the feasibility of estimating the iridocorneal angle (ICA) using smartphone-captured images.
- To compare smartphone-based ICA measurements with a gold-standard imaging technique.
Main Methods:
- Utilized smartphone images to estimate the inferior iridocorneal angle (ICA).
- Compared smartphone-derived ICA measurements with anterior segment optical coherence tomography (AS-OCT) measurements at 500 μm and 270 degrees.
Main Results:
- Smartphone-measured inferior ICA showed no significant difference compared to AS-OCT measurements (P=0.06).
- An excellent positive correlation (ρ=0.81, P<0.001) was observed between the two methods.
Conclusions:
- Smartphone image-aided estimation provides a simple, effective, and economical approach for quantifying ICAs.
- This method holds promise for the early identification of angle-closure disease.

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

01:27Open Angle Glaucoma: Treatment
969
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.

01:13Angle of Twist: Problem Solving
762
An electric motor applies a torque of 700 N·m to an aluminum shaft, triggering a stable rotation. Two pulleys, B and C, are subjected to torques of 300 N·m and 400 N·m, respectively. The modulus of rigidity is provided as 25 GPa. With the knowledge of the length and diameter of each segment, the twist angle between the two pulleys can be computed. First, a section cut is made between pulleys B and C, and the cut cross-section is analyzed using a free-body diagram. Given that the torque...

01:28Angle Closure Glaucoma: Treatment
1.2K
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...

Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

01:13Angle of Twist - Elastic Range

Consider a cylindrical shaft with a length denoted by L and a consistent cross-sectional radius referred to as r. This shaft undergoes a torque at the free end. The highest shearing strain within the shaft is directly proportional to the twist angle and the radial distance from the shaft axis. When the shaft behaves elastically, this shearing strain can be articulated using variables such as the applied torque, radial distance, the polar moment of inertia, and the modulus of rigidity. By...
