PCO!



-Most common complication of cataract surgery.


Lens Epithelial Cells → Migration → Proliferation → Differentiation


Two types of PCO:


1) FIBROUS:

Abnormal proliferation of LEC → presents as wrinkles and folds on the posterior capsule site at the fusion of anterior and posterior capsules


2) PROLIFERATIVE → Elsching’s Pearls


Elsching’s Pearls result from aberrant attempts by lens cells attached to the capsule to form new lens fibres


-Normally differentiated LEC that line the equatorial lens region migrate and proliferate between posterior capsule and the IOL.


-Clusters of residual LEC appear as round, clear pearls that shine on retro-illumination → Appearance of a bunch of grapes/ soap bubbles/ mass of fish eggs.


-Decreased visual acuity if they accumulate on visual axis.



HISTOLOGY:


-Large clear lens cells (bladder cells) are seen behind iris, pupillary space or both areas



TREATMENT:


-Nd:YAG Laser Capsulotomy
