COLOR PLATE 2 A. Calcium oxalate crystal in lens nucleus, as seen with polarized light (H & E, × 146). B. Lens compressed by a ciliochoroidal malignant melanoma (lower right). Changes include cortical liquefaction and nuclear fragmentation (H & E, × 23.4). C. Capsular remnants 6 weeks after extracapsular lens extraction. Only capsule and epithelium remain. D. Capsular remnants years after lens extraction. Lens fibers can proliferate from remaining epithelium (C and D, H & E, × 23.4).
