Glaucoma: Overview

1.0K
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

934
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: Treatment01:27

Open Angle Glaucoma: Treatment

808
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

Late in-the-bag intraocular lens (IOL) dislocation occurs in 0.5-3% of cases, typically years after cataract surgery. IOL repositioning or exchange offers safe, satisfactory visual outcomes, but evidence quality is low.

Area of Science:

  • Ophthalmology
  • Clinical Research

Background:

  • Late in-the-bag intraocular lens (IOL) dislocation is a complication following cataract surgery.
  • Understanding its incidence, patient factors, and treatment is crucial for patient care.

Purpose of the Study:

  • To review the cumulative incidence, patient characteristics, predisposing conditions, and treatment outcomes for late in-the-bag IOL dislocation.

Main Methods:

  • A comprehensive literature search was conducted across PubMed (MEDLINE), Embase, and Cochrane Library Central.
  • Included studies comprised 1 randomized clinical trial, 1 prospective case series, 2 prospective cohort studies, and 36 retrospective studies.

Main Results:

  • The cumulative incidence of late IOL dislocation ranged from 0.5% to 3%, occurring 6–12 years post-surgery in patients aged 65–85 years.
  • Common predisposing factors included pseudoexfoliation syndrome, myopia, and prior vitreoretinal surgery.
  • IOL repositioning and IOL exchange demonstrated comparable visual outcomes and safety profiles.

Conclusions:

  • Late in-the-bag IOL dislocation has a low cumulative incidence, with identifiable risk factors.
  • Surgical interventions like repositioning or exchange yield satisfactory long-term visual results.
  • High-quality clinical trials are needed to further evaluate treatment strategies and surgical techniques.
