Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

885
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...

Angle Closure Glaucoma: Treatment

1.0K
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...

Glaucoma: Overview

1.1K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Summary
This summary is machine-generated.

Bariatric surgery significantly reduces body mass index (BMI) and intraocular pressure (IOP) after one year. This BMI reduction is linked to continued IOP decline, suggesting potential benefits for ocular hypertension management.

Area of Science:

  • Ophthalmology
  • Metabolic Surgery
  • Obesity Research

Background:

  • The relationship between body mass index (BMI) reduction post-bariatric surgery and intraocular pressure (IOP) requires further investigation.
  • Bariatric surgery leads to significant weight loss, potentially impacting various physiological parameters, including ocular health.

Purpose of the Study:

  • To evaluate the association between BMI reduction and IOP measurements one year after bariatric surgery.
  • To assess other ocular and metabolic parameters in relation to BMI changes post-surgery.

Main Methods:

  • A retrospective study analyzed data from 22 patients who underwent bariatric surgery (LSG or MGB) between 2016 and 2016.
  • Follow-up extended over one year, collecting data on BMI, IOP, central corneal thickness, and retinal nerve fiber layer thickness.

Main Results:

  • Average BMI decreased significantly from 41.9 to 25.5 kg/m² (p < 0.001) one year post-surgery.
  • Mean IOP showed a significant 21% decrease (p < 0.001), correlated with preoperative IOP and corneal thickness.
  • Central corneal thickness and retinal nerve fiber layer thickness also decreased significantly (p = 0.038 and p = 0.018, respectively).

Conclusions:

  • BMI reduction following bariatric surgery is associated with a sustained decrease in IOP beyond one year.
  • These findings suggest that bariatric surgery may be a relevant consideration for patients with ocular hypertension.
