Glaucoma: Overview

988
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...

Angle Closure Glaucoma: Treatment

890
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...

Summary

Routine intravitreal triamcinolone acetonide and long-term NSAIDs reduced cystoid macular edema (CME) after Gore-Tex suture intraocular lens (IOL) fixation for pseudoexfoliation syndrome. This prophylaxis improved visual acuity and lowered CME incidence compared to NSAIDs alone.

Area of Science:

  • Ophthalmology
  • Retinal Diseases
  • Surgical Innovation

Background:

  • Pseudoexfoliation syndrome can lead to spontaneous intraocular lens (IOL) dislocation, necessitating surgical intervention.
  • Scleral fixation of IOLs, particularly with Gore-Tex sutures, is a technique used to address IOL instability.
  • Cystoid macular edema (CME) is a potential complication following intraocular surgeries, including IOL fixation procedures.

Purpose of the Study:

  • To evaluate the incidence of cystoid macular edema (CME) after 4-point Gore-Tex suture intraocular lens (IOL) scleral fixation.
  • To compare CME rates before and after implementing routine intravitreal triamcinolone acetonide prophylaxis and long-term topical nonsteroidal anti-inflammatory drug (NSAID) use.
  • To assess the impact of this prophylactic regimen on visual outcomes in patients with pseudoexfoliation syndrome.

Main Methods:

  • A consecutive series of patients undergoing IOL implantation with pars plana vitrectomy for pseudoexfoliation-related IOL dislocation were studied.
  • Group A received short-term prophylactic NSAIDs only.
  • Group B received prophylactic intravitreal triamcinolone acetonide combined with long-term topical NSAIDs.

Main Results:

  • Twenty-six eyes with pseudoexfoliation syndrome and IOL dislocation were analyzed.
  • Mean visual acuity significantly improved postoperatively in both groups (P < 0.001).
  • Group A had a higher incidence of CME (10/16 eyes) compared to Group B (1/10 eyes), with Group B's CME being chronic and refractory.

Conclusions:

  • 4-point Gore-Tex suture IOL scleral fixation provides good visual outcomes for pseudoexfoliation syndrome with IOL dislocation.
  • The incidence of CME was higher than previously reported, underscoring the need for effective prophylaxis.
  • Prophylactic intravitreal triamcinolone acetonide and long-term NSAIDs appear to effectively reduce the risk of postoperative CME.
