Focusing of Light in the Eye01:16

Focusing of Light in the Eye

2.4K
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...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

537
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

389
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...

Accessory Structures of the Eye

1.4K
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

433
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...

Summary

Modifying peripheral optics with myopia control lenses or partially excised glasses did not impact accommodation responses in adults or children. These findings suggest peripheral optical changes do not influence the eye's focusing ability.

Area of Science:

  • Ophthalmology
  • Optometry
  • Vision Science

Background:

  • Peripheral optics are implicated in myopia progression.
  • Accommodation responses are also considered potential contributors to myopia.
  • Investigating the interplay between peripheral optics and accommodation is crucial for understanding myopia development.

Purpose of the Study:

  • To determine if altering peripheral optics with specific spectacle lenses affects accommodation responses.
  • To compare the effects of different myopia control lenses on accommodation.
  • To assess the impact of partially excised glasses on accommodation.

Main Methods:

  • Dynamic accommodation was measured using a double-pass instrument during target distance changes.
  • Adults and children were fitted with myopia control lenses (MiYOSMART, Stellest, MyoCare) or standard glasses with central holes.
  • Testing included central and peripheral visual field assessments with various lens refractions.

Main Results:

  • Accommodative lag was consistently below 0.5 D under near stimulation across all groups.
  • No statistically significant differences in accommodation amplitude were found between myopia control lenses and partially excised glasses.
  • Habitual glasses served as a reference point for comparison.

Conclusions:

  • Modifications to peripheral optics using tested myopia control lenses do not significantly alter accommodation responses.
  • Partially excised glasses also showed no impact on accommodation.
  • These results suggest that induced peripheral optical changes may not influence the accommodative system.
