Angle Closure Glaucoma: Treatment

Angle 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...

Summary

Dense nuclear cataracts and peripheral corneal degenerations increase the risk of transient corneal edema after phacoemulsification. Using the phaco-chop technique and minimizing phaco-power time can reduce this complication.

Background:

Transient corneal edema is a potential complication following phacoemulsification.
Identifying pre-operative and intra-operative risk factors is crucial for patient management.

Purpose of the Study:

To investigate factors associated with transient corneal edema after phacoemulsification and Intraocular Lens (IOL) implantation.

Main Methods:

A cohort study was conducted with 182 patients undergoing phacoemulsification.
Pre-operative factors (cataract density, corneal degenerations) and surgical factors (technique, phaco-power time) were analyzed.
Postoperative corneal clarity and striate keratopathy were assessed.

Main Results:

Hypertension, dense nuclear cataracts, divide and conquer technique, prolonged phaco-power use, and peripheral corneal degenerations were associated with increased risk.
Peripheral corneal degenerations (p < 0.001) and dense nuclear cataracts (p=0.006) showed significant association.

Conclusions:

Peripheral corneal degenerations and dense nuclear cataracts are significant risk factors for postoperative corneal edema.
Employing the phaco-chop technique and reducing phaco-power time can mitigate the incidence of corneal edema.
