Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.5K
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...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.5K
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: 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...

Area of Science:

  • Neuroscience
  • Ophthalmology
  • Vision Science

Background:

  • Acquired brain injury can lead to debilitating binocular vision disorders.
  • These disorders often manifest as convergence insufficiency, impacting daily activities.
  • Effective treatment options for post-brain injury vision problems are crucial.

Purpose of the Study:

  • To prospectively evaluate the effectiveness of home-based computer vergence therapy.
  • To assess treatment outcomes for binocular vision disorders in adults at least 3 months after an acquired brain injury.

Main Methods:

  • Nineteen adults with diagnosed binocular dysfunction post-brain injury were enrolled.
  • Participants underwent 12 weeks of prescribed home-based computer vergence therapy.
  • Key metrics including near point of convergence, vergence facility, and symptoms (CISS) were measured at baseline and various intervals.

Main Results:

  • Statistically significant improvements were observed in near point of convergence, vergence facility, and convergence insufficiency symptom survey scores (p < 0.001).
  • High success rates were reported: 69% for near point of convergence, 77% for fusional vergence, and 92% for vergence facility.
  • The majority of participants completing the study showed meaningful clinical improvements.

Conclusions:

  • Home-based computer vergence therapy is an effective treatment for binocular vision disorders after acquired brain injury.
  • The therapy leads to significant improvements in both objective measures and subjective symptoms.
  • This approach offers a viable and accessible treatment option for this patient population.
