[Bilateral postoperative myopic shift and rise in intraocular pressure after cataract surgery].

Ophthalmologe 2021 Apr;118(4):391-393

Augenärztliches Operationszentrum Fulda, Fulda, Hessen, Deutschland.

Malignant glaucoma describes a rare constellation with shallowing of the anterior chamber and raised intraocular pressure, which can occur after ocular surgery, trauma or spontaneously. The pathophysiological mechanism seems to consist of a posteriorly directed flow of the aqueous humor formed in the ciliary body into or behind the vitreous body. Most cases can only be treated by surgical intervention. Read More
