Glaucoma: Overview

1.1K
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

1000
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

Posterior intraocular lens (IOL) dislocation factors differ based on whether the IOL was initially in or out of the bag. Surgical management improved visual acuity with a low complication rate.

Area of Science:

  • Ophthalmology
  • Surgical Complications
  • Intraocular Lens Implantation

Background:

  • Intraocular lens (IOL) dislocation into the posterior segment is a known complication after cataract surgery.
  • Understanding predisposing factors and management strategies is crucial for optimizing patient outcomes.

Purpose of the Study:

  • To evaluate the predisposing factors for intraocular lens (IOL) dislocation into the posterior segment.
  • To analyze the management approaches and visual prognosis for eyes with dislocated IOLs.

Main Methods:

  • Retrospective review of 72 eyes with posterior IOL dislocation from January 2012 to May 2017.
  • Inclusion criteria: eyes requiring IOL explantation or repositioning.
  • Data collected: predisposing factors, time to dislocation, onset circumstances, management, and complications.

Main Results:

  • Mean age was 67.6 years; 68% were male.
  • Shorter interval to dislocation for out-of-the-bag vs. in-the-bag IOLs (3.8 vs. 132 months).
  • Predisposing factors included capsular/zonular issues (out-of-the-bag) and high myopia/pseudoexfoliation (in-the-bag).

Conclusions:

  • Distinct predisposing factors and timing exist for out-of-the-bag versus in-the-bag IOL dislocations.
  • Management varied, with anterior and posterior approaches used for repositioning or replacement.
  • Surgical intervention significantly improved visual acuity with a low complication rate (9.7%).
