Glaucoma: Overview01:25

Glaucoma: Overview

919
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

843
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

717
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...

COPD: Pathogenesis and Clinical Features

648
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

6.6K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Accessory Structures of the Eye01:17

Accessory Structures of the Eye

2.0K
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.

The COVID-19 pandemic significantly increased myopia progression in children by 35% due to reduced outdoor time and increased screen use. Factors like heredity and close work exacerbated this, while rest and sleep offered protection.

Area of Science:

  • Ophthalmology
  • Public Health
  • Pediatrics

Background:

  • Myopic progression is a growing concern in children.
  • The coronavirus disease 2019 (COVID-19) pandemic led to widespread home confinement, altering lifestyle factors.
  • Understanding the impact of these changes on pediatric myopia is crucial.

Purpose of the Study:

  • To compare myopic progression in children before and during COVID-19 home confinement.
  • To identify factors influencing myopia progression during this period.

Main Methods:

  • A cross-sectional study involving 115 myopic children.
  • Compared axial length and refractive errors before and after 3 months of strict home confinement.
  • Utilized questionnaires and visual function tests to assess influencing factors.

Main Results:

  • Monthly axial elongation increased by 35% during confinement (0.046 vs. 0.033 mm/month).
  • Severe asthenopia doubled during confinement.
  • Heredity, close indoor work, and screen time were risk factors; age, rest, sleep, and viewing distance were protective.

Conclusions:

  • COVID-19 home confinement accelerated myopia progression by approximately one-third.
  • Reduced outdoor activities and increased digital screen exposure are key drivers.
  • Lifestyle modifications are essential for managing pediatric myopia during pandemics.
