Summary
Smartphone gonioimaging offers a portable, user-friendly method for glaucoma screening. This technique uses a smartphone and goniolens to visualize the anterior chamber angle, aiding in early glaucoma detection.
Area of Science:
- Ophthalmology
- Medical Imaging
- Glaucoma Diagnosis
Background:
- Gonioscopy is crucial for glaucoma diagnosis and management but requires specialized skills.
- Ophthalmology imaging has been transformed by portable smartphone-based solutions.
- Acquiring gonioscopy skills can be challenging for ophthalmologists.
Purpose of the Study:
- To describe a novel smartphone-based gonioimaging technique.
- To evaluate its utility as a screening tool for glaucoma.
Main Methods:
- A smartphone was coupled with a 4-mirror goniolens.
- The technique was used to image the anterior chamber angle.
- The imaging allowed for detection of gross anatomical findings.
Main Results:
- The described technique successfully captured images of the anterior chamber angle.
- Gross findings indicative of potential glaucoma could be identified.
Conclusions:
- Smartphone-based gonioimaging is a feasible and accessible method.
- This technique can serve as a valuable screening tool for glaucoma, particularly in resource-limited settings.

01:27Conjugate Addition (1,4-Addition) vs Direct Addition (1,2-Addition)
4.2K
α,β-Unsaturated carbonyl compounds with two electrophilic sites, the carbonyl carbon, and the β carbon, are susceptible to nucleophilic attack via two modes: conjugate or 1,4-addition and direct or 1,2-addition.
Conjugate addition results in a thermodynamically stable product. The reaction retains the stronger C=O bond at the expense of the weaker C=C π bond. The process is slow as the β carbon is less electrophilic than the carbonyl carbon.
Direct addition products are...

01:25Glaucoma: Overview
1.3K
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...

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.

The attack of a nucleophile at the β carbon of an α,β-unsaturated carbonyl compound is called conjugate addition. Conjugate addition reactions of active methylene compounds, such as β-diketones, β-keto esters, β-keto nitriles, and α-nitro ketones, are called Michael addition reactions.

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...
