Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

905
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

778
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...

Muscles of the Eye

2.5K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Accessory Structures of the Eye

2.4K
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...

Summary
This summary is machine-generated.

Augmented bilateral lateral rectus recession effectively treats consecutive exotropia, with 89% of patients achieving successful alignment. This surgical enhancement improves binocular vision but does not restore stereopsis.

Area of Science:

  • Ophthalmology
  • Strabismus Surgery

Background:

  • Consecutive exotropia can impair binocular vision.
  • Standard surgical approaches may have limitations.

Purpose of the Study:

  • To assess the effectiveness of augmented bilateral lateral rectus recession.
  • To evaluate this technique for consecutive exotropia treatment.

Main Methods:

  • Retrospective review of nine patients with consecutive exotropia.
  • Augmented bilateral lateral rectus recession with 1.5-2 mm additional recession.
  • Postoperative alignment measured using prism and alternate cover testing (PACT).

Main Results:

  • Eight of nine patients (89%) achieved successful outcomes.
  • Successful realignment led to monofixation syndrome in most.
  • No significant restoration of stereopsis was observed.

Conclusions:

  • Augmented bilateral lateral rectus recession is effective for treating consecutive exotropia.
  • This method restores binocular alignment for distance and near fixation.
  • It may be preferable to bimedial advancements in specific patient groups.
