Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

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...

Focusing of Light in the Eye

Focusing of Light in the Eye

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: Treatment

Open Angle Glaucoma: Treatment

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...

Background:

Progressive myopia in young adults presents a significant challenge.
Understanding the plasticity of the accommodative system is crucial for myopia management.
Nearwork-induced transient myopia (NITM) is a common phenomenon associated with prolonged near tasks.

Purpose of the Study:

To evaluate the impact of a 6-week home-based accommodative training program on NITM parameters.
To assess changes in accommodative accuracy and facility following the training.
To investigate the effects of training on asymptomatic, progressing myopes.

Main Methods:

Ten young adult myopes underwent a 6-week vision training regimen.
Training involved accommodative flippers, Hart charts, and prism flippers for 20 minutes daily, 5 days a week.
Accommodative functions were measured at baseline, 3 weeks, and 6 weeks.

Main Results:

Significant improvements were observed in dynamic accommodative response measures, including lens flipper and Hart chart rates.
Lens flipper rate increased significantly in the right eye (OD), left eye (OS), and both eyes (OU).
Hart chart rate showed significant improvement in OD and OS.
A negative correlation was found between lens flipper rate and NITM decay duration post-training.

Conclusions:

Home-based accommodative training effectively enhanced the dynamics of the accommodative system in progressing myopes.
Improvements were noted in both laboratory-based and clinically relevant measures of accommodation.
Findings support the potential of targeted vision training for myopia management.
