Muscles of the Eye01:20

Muscles of the Eye

5.2K
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...

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...

Open Angle Glaucoma: Treatment01:27

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...

Summary
This summary is machine-generated.

Partial tendon recession effectively corrects small vertical deviations, with 82% of patients resolving double vision. Results are reliable for thyroid eye disease but less predictable for reoperated muscles.

Area of Science:

  • Ophthalmology
  • Strabismus Surgery
  • Oculomotor Muscle Procedures

Background:

  • Vertical deviations can cause significant visual disturbances.
  • Surgical correction is often necessary for small-angle vertical deviations.
  • Partial tendon recession is a surgical technique used to address these deviations.

Purpose of the Study:

  • To assess the efficacy of partial tendon recession in correcting small vertical deviations.
  • To evaluate outcomes including orthophoria, residual deviation, and torsion.
  • To analyze outcomes in specific patient groups, including those with thyroid eye disease and prior muscle surgery.

Main Methods:

  • Retrospective review of medical records for patients undergoing partial tendon recession.
  • Inclusion of 53 procedures in 44 patients.
  • Primary success criterion was orthophoria; secondary analyses included residual deviation, torsion, and dose-response.

Main Results:

  • Mean preoperative vertical deviation of 4.3Δ improved to 0Δ postoperatively.
  • 62% of procedures achieved orthophoria; 82% of patients had vertical diplopia resolution.
  • Outcomes were favorable in thyroid eye disease (60% orthophoria) but less predictable in reoperated muscles (29% orthophoria).

Conclusions:

  • Partial tendon recession is a reliable method for correcting small vertical deviations.
  • The procedure is effective in patients with thyroid eye disease.
  • Surgical outcomes are less predictable in muscles that have undergone previous surgery.
