Lens Dislocation Following YAG Laser Peripheral Iridotomy
Summary
Repeated laser peripheral iridotomy can rarely cause crystalline lens dislocation into the vitreous. Surgical intervention successfully restored vision, highlighting a potential risk of this common ophthalmic procedure.
Area of Science:
- Ophthalmology
- Surgical Procedures
- Complications of Medical Interventions
Background:
- Laser peripheral iridotomy (LPI) is a standard treatment for angle-closure glaucoma.
- Complications, though rare, necessitate thorough understanding and management strategies.
Purpose of the Study:
- To report a unique case of crystalline lens dislocation following LPI.
- To discuss the management and implications of this rare complication.
Main Methods:
- A case report detailing a patient who experienced lens dislocation post-LPI.
- Surgical management included pars plana vitrectomy, fragmatome lensectomy, and anterior chamber intraocular lens implantation.
- A final surgical iridotomy was performed.
Main Results:
- The patient achieved a best corrected visual acuity of 6/9 post-operatively.
- Successful management of a rare complication of LPI was demonstrated.
Conclusions:
- Multiple sessions of LPI may increase the risk of complete lens dislocation.
- Prompt surgical intervention is crucial for managing this sight-threatening complication.

01:28Angle 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...
01:25Glaucoma: 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...
01:27Open 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.

01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
