pseudoexfoliation
Pronunciation: SOO-doh-ex-foh-lee-AY-shun
Age-related condition involving deposition of fibrillar material on ocular structures. Significantly complicates cataract surgery due to zonular weakness.
Full Definition
A systemic disorder characterized by the production and accumulation of abnormal extracellular material throughout the anterior segment of the eye and other organs. In ophthalmic surgery, pseudoexfoliation syndrome presents significant challenges due to its association with zonular weakness, increased surgical complications, and higher rates of post-operative pressure elevation. The condition requires modified surgical techniques, longer operative times, and enhanced post-operative monitoring. Recognition of pseudoexfoliation is crucial for appropriate surgical planning and informed consent discussions.
Usage
Usage note: Often abbreviated as PEX; distinguish from true exfoliation which is different condition.
