Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

887
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: Treatment

748
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...

Glaucoma: Overview01:25

Glaucoma: Overview

961
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...

Area of Science:

  • Ophthalmology
  • Glaucoma Management
  • Surgical Techniques

Background:

  • Primary chronic angle-closure glaucoma (CACG) presents a significant challenge in vision preservation.
  • Coexisting visually significant cataracts complicate CACG management.
  • Effective treatment strategies are crucial for reducing intraocular pressure (IOP) and preventing vision loss.

Purpose of the Study:

  • To evaluate the safety and efficacy of microscopic cyclophotocoagulation (CPC) combined with phacoemulsification in patients with CACG and cataracts.
  • To assess the impact of this combined surgical approach on intraocular pressure (IOP), best-corrected visual acuity (BCVA), and medication requirements.
  • To document and analyze any surgery-associated complications.

Main Methods:

  • Retrospective review of 35 eyes (35 patients) with CACG and cataracts.
  • Combined procedure: cyclophotocoagulation under microscopic direct vision and phacoemulsification.
  • Minimum 12-month postoperative follow-up.
  • Data collected: BCVA, IOP, number of antiglaucoma medications, and complications.

Main Results:

  • Significant improvement in BCVA (1.15 ± 0.91 to 0.86 ± 0.82 logMAR, P < 0.0001).
  • Marked reduction in IOP (36.63 ± 13.50 to 15.14 ± 3.19 mmHg, P < 0.0001).
  • Substantial decrease in antiglaucoma medications (2.23 ± 0.55 to 0.54 ± 0.86, P < 0.0001).
  • Significant reduction in mean defect and retinal nerve fiber layer thickness postoperatively.
  • One instance of intraoperative suprachoroidal hemorrhage managed successfully; no additional surgeries required.

Conclusions:

  • Microscopic cyclophotocoagulation with phacoemulsification is a safe and effective treatment for primary chronic angle-closure glaucoma with cataracts.
  • The combined procedure offers significant IOP reduction, visual acuity improvement, and decreased medication dependence.
  • This approach demonstrates a favorable safety profile with manageable complications.
