Summary
A rare case of spontaneous iris avulsion occurred during cataract surgery wound hydration. This highlights the critical importance of managing intraocular pressure during this surgical step to prevent iris complications.
Area of Science:
- Ophthalmology
- Surgical Complications
Background:
- Phacoemulsification is a common cataract surgery technique.
- Intraocular lens implantation and viscoelastic removal are standard procedures.
Observation:
- Spontaneous total iris avulsion occurred during corneal wound hydration post-phacoemulsification.
- The iris prolapsed through the main surgical wound into the anterior chamber.
Findings:
- The complication occurred despite an otherwise uneventful cataract surgery.
- No further surgical intervention was required after the avulsion.
- Best corrected visual acuity of 20/50 was achieved four months postoperatively.
Implications:
- This case underscores the significance of understanding pressure dynamics during corneal wound hydration.
- Awareness of potential iris avulsion is crucial for ophthalmic surgeons.
- Careful wound hydration technique can mitigate risks of anterior segment complications.

360
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
465
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...
