Ans.B. After cataract
The above image shows Elschnig’s pearls which are a type of after cataract—a delayed complication of cataract surgery.
Elschnig’s pearls: vacuolated subcapsular epithelial cells are clustered like soap bubbles along the posterior capsule.
Types of after cataract:
- Thin membranous after-cataract (thickened posterior capsule).
- Dense membranous after-cataract
- Soemmerring’s ring after-cataract: which refers to a thick ring of after cataract formed behind the iris, enclosed between the two layers of capsule
- Elschnig’s pearls: in which the vacuolated subcapsular epithelial cells are clustered like soap bubbles along the posterior capsule
Treatment is as follows :
i. Thin membranous after cataract and thickened posterior capsule are best treated by YAG-laser capsulotomy or discission with cystotome or Zeigler’s knife.
ii. Dense membranous after cataract needs surgical membranectomy.
iii. Soemmering’s ring after cataract with clean central posterior capsule needs no treatment.
iv. Elschnig’s pearls involving the central part of the posterior capsule can be treated by YAG-laser capsulotomy or discission with cystotome.
