Glaucoma: Overview01:25

Glaucoma: Overview

570
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

449
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

498
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

1.6K
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.

Computer use impacts the ocular surface in post-LASIK individuals, causing dry eye signs. Artificial tears effectively prevent these computer-related effects on the ocular surface in patients who underwent laser in situ keratomileusis (LASIK).

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Dry Eye Disease

Background:

  • Computer use is prevalent and may affect ocular surface health.
  • Laser in situ keratomileusis (LASIK) alters corneal structure, potentially influencing post-operative ocular surface responses.
  • Understanding the impact of digital device usage on post-LASIK patients is crucial for managing visual comfort.

Purpose of the Study:

  • To evaluate the effects of computer use on the ocular surface in individuals who have undergone LASIK.
  • To compare the ocular surface response to computer use between post-LASIK patients and a control group.
  • To determine the efficacy of artificial tears in mitigating computer-induced ocular surface changes in post-LASIK eyes.

Main Methods:

  • A comparative study involving 18 post-LASIK individuals and 18 controls.
  • Assessment of dry eye symptoms using OSDI, SANDE II, and CVS-Q questionnaires.
  • Ocular surface evaluation included corneal aberrations, tear meniscus height, conjunctival redness, blink rate, and lipid layer thickness before and after a 30-minute computer task, with and without artificial tears.

Main Results:

  • Post-LASIK individuals exhibited increased conjunctival redness, reduced tear meniscus height, and decreased non-invasive keratograph break-up time after computer use.
  • No significant differences in dry eye symptoms (SANDE II, CVS-Q) were found between post-LASIK and control groups.
  • Artificial tear instillation at Visit 2 significantly reduced dry eye symptoms and prevented worsening of ocular surface signs in both groups, particularly in post-LASIK patients.

Conclusions:

  • While ocular symptoms during computer use were similar between groups, post-LASIK individuals showed a greater deterioration in dry eye signs.
  • Artificial tears proved effective in preventing adverse ocular surface effects associated with computer use in post-LASIK patients.
  • This study highlights the importance of artificial tear use for managing ocular surface discomfort in individuals after LASIK during prolonged computer tasks.
