[Postoperative maximum dilated fixed pupil and primary graft insufficiency after penetrating keratoplasty]
Abstract:
Postoperative maximum dilated fixed pupil after penetrating keratoplasty, so-called Urrets-Zavalia syndrome, is rare. Primary insufficiency of the graft can necessitate a repeat keratoplasty. Subsequently, a segmental artificial iris reconstruction might be beneficial.

Glaucoma: Overview
1.5K
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
1.4K
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...
