Glaucoma: Overview01:25

Glaucoma: Overview

703
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...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

3.1K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

528
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

630
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...

Prescription, Nonprescription and Orphan Drugs

835
Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Accessory Structures of the Eye01:17

Accessory Structures of the Eye

1.7K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Summary
This summary is machine-generated.

National affluence significantly impacts the prescribing of daily disposable and toric soft contact lenses. Reducing cost barriers can improve access to these clinically important lens types.

Area of Science:

  • Ophthalmology and Optometry
  • Public Health
  • Health Economics

Background:

  • Prescribing patterns for soft contact lenses vary globally.
  • National economic status may influence the adoption of advanced contact lens technologies.

Purpose of the Study:

  • To investigate the correlation between a nation's economic affluence, measured by Gross Domestic Product (GDP) at Purchasing Power Parity per capita, and the prevalence of prescribing specific types of soft contact lenses.
  • To analyze the relationship between national affluence and the prescribing rates of daily disposable, toric, silicone hydrogel, and multifocal contact lenses.

Main Methods:

  • Utilized a comprehensive dataset of contact lens prescriptions from 39 countries between 2017 and 2021.
  • Analyzed 94,181 contact lens fits, correlating the percentage of specific lens type prescriptions with GDP (PPP).

Main Results:

  • A statistically significant positive association was found between national affluence and the prescribing of daily disposable lenses (r² = 0.35, P < 0.0001).
  • A marginally significant relationship was observed for toric lenses (r² = 0.08, P = 0.06).
  • No significant correlation was found for silicone hydrogel (r² = 0.01, P = 0.42) or multifocal lenses (r² = 0.02, P = 0.35).

Conclusions:

  • National affluence is a key factor influencing the prescription rates of daily disposable and, to some extent, toric soft contact lenses.
  • Stakeholders in the contact lens industry, including practitioners and regulatory bodies, should consider strategies to mitigate cost barriers, enabling prescription based on clinical needs and patient lifestyle.
