Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

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: Overview01:25

Glaucoma: Overview

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...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

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:

  • Ophthalmology
  • Surgical Techniques
  • Retina Surgery

Background:

  • Pars plana lensectomy is often required in combined cataract and vitreoretinal surgery.
  • Maintaining intraocular lens (IOL) stability and a clear visual axis is crucial in these complex cases.

Observation:

  • A novel optic capture pars plana lensectomy technique is described.
  • This technique involves preserving the anterior capsule during lensectomy and capturing the IOL optic within the capsulorhexis margin.

Findings:

  • The optic capture technique resulted in a stable IOL-capsule diaphragm.
  • This stability prevented anterior chamber air prolapse during air-fluid exchange.
  • A clear visual axis was maintained throughout the follow-up period.

Implications:

  • This modified technique offers a solution for stable IOL positioning in pars plana approaches.
  • It is particularly beneficial for combined cataract and vitreoretinal procedures.
  • Ensures optimal visual outcomes and surgical success in complex ophthalmic surgeries.
