11 Lens and Cataract
Chapter 5: Pathology
Lens Particle Glaucoma
Following a penetrating lens injury or surgical procedure (ie, extracapsular cataract extraction, phacoemulsification with retained cortical material, or in rare instances, Nd:YAG laser capsulotomy or vitrectomy), particles of lens cortex may migrate into the anterior chamber, where they obstruct aqueous outflow through the trabecular meshwork. In most instances, glaucoma occurs within weeks of the initial surgery or trauma, but it may occur months or years later. Gonioscopy shows that the angle is open, and cortical material can often be seen deposited along the trabecular meshwork. Medical therapy to lower IOP and to reduce intraocular inflammation is indicated. If the IOP and inflammation do not respond quickly to this treatment, the retained lens material is removed surgically.
