Glaucoma: Overview01:25

Glaucoma: Overview

1.7K
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

1.1K
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

1.6K
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...

Accessory Structures of the Eye01:17

Accessory Structures of the Eye

4.3K
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...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

6.2K
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

861
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Summary

Standard myopic LASIK surgery increases corneal aberrations, which worsen with age. Cataract surgery also increases aberrations, suggesting long-term optical challenges for patients.

Area of Science:

  • Ophthalmology
  • Optics
  • Vision Science

Background:

  • Ocular aberrations change with age and after refractive surgery.
  • Standard myopic LASIK and cataract surgery impact corneal and overall ocular aberrations.
  • Understanding these changes is crucial for predicting long-term visual outcomes.

Purpose of the Study:

  • To review current knowledge on how ocular aberrations change with aging, cataract surgery, and LASIK.
  • To speculate on the long-term effects of these changes on vision after LASIK.
  • To discuss potential future optical corrections for age-related and surgery-induced aberrations.

Main Methods:

  • Literature review of studies on ocular aberrations.
  • Analysis of changes in aberrations after myopic LASIK.
  • Evaluation of aberration changes associated with aging and cataract surgery.

Main Results:

  • Standard myopic LASIK significantly increases corneal aberrations, especially positive spherical aberration.
  • Ocular aberrations naturally increase with age, with crystalline lens aberration shifting towards positive values.
  • Post-LASIK aberrations are expected to worsen with age, without compensatory effects.
  • Cataract surgery with standard IOLs results in higher aberrations than in young, healthy eyes.

Conclusions:

  • Long-term visual quality after standard myopic LASIK may be compromised by age-related aberration increases.
  • Aberrations induced by LASIK or present after cataract surgery may not be fully corrected by age-related changes.
  • Future advancements may involve customized IOLs and ablation techniques to mitigate long-term aberration issues.
