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...

Ophthalmic Drug Delivery Systems

Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
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...

Summary

Phacoemulsification (cataract surgery) in vitrectomized eyes is safe and effective under topical anesthesia. Most patients experienced improved vision with minimal complications, making it a visually rewarding procedure.

Area of Science:

  • Ophthalmology
  • Surgical Innovation

Background:

  • Phacoemulsification is a common cataract surgery technique.
  • Vitrectomized eyes present unique challenges for cataract surgery due to altered anatomy and biomechanics.

Purpose of the Study:

  • To evaluate the safety and efficacy of phacoemulsification in eyes previously treated with pars plana vitrectomy.
  • To assess the suitability of topical anesthesia for this patient group.
  • To document intraoperative characteristics and potential complications.

Main Methods:

  • A prospective study involving 52 eyes of 51 patients who underwent phacoemulsification after pars plana vitrectomy.
  • Procedures were performed under topical anesthesia.
  • Surgical observations, anesthetic effectiveness, visual outcomes, and complications were meticulously recorded.

Main Results:

  • 92% of patients achieved improved visual acuity postoperatively.
  • Topical anesthesia was satisfactory for 96% of patients, with no conversions to injection anesthesia required.
  • Common intraoperative findings included deep anterior chamber, posterior capsular plaques, posterior synechiae, and nuclear sclerotic cataracts. No major complications occurred.

Conclusions:

  • Phacoemulsification in vitrectomized eyes is a feasible and visually beneficial procedure.
  • Topical anesthesia is a safe and effective anesthetic option for the majority of these complex cases.
