Disease | Main changes |
|
Cataract | Lower surface roughness in the anterior side of the ALC and higher surface roughness in their posterior side |
Lower Young’s modulus |
Ultrastructure morphology changes in intumescent white cataracts |
Trypan blue staining | Decrease in elasticity and an increase in stiffness |
No difference in CCC strength |
Aniridia | Thinner and more fragile |
Degenerative changes (degeneration, necrosis, and loss) and proliferative changes (proliferation and double layer) of the lens epithelium |
Climatic droplet keratopathy | Plateau or “bag” or herniation-like of the lens capsule |
Exfoliation syndrome | Abnormal fibrillar extracellular material deposition |
Diffuse intracellular and extracelluar edema, transparent vacuoles, apoptotic cells, and destroyed epithelial cells |
More affinity to trypan blue |
True exfoliation syndrome | Thickened delaminated structure, perpendicular fibrils, and vesicular degeneration in the ALC |
Double delamination and pigment deposition on the detached membrane |
Alport syndrome | Marked thinning and vertical dehiscence of the ALC |
Spontaneous rupture of the ALC |
Silicone oil tamponade | Surface irregularities, pits, and depressions in the posterior surface of the ALC |
LECs with apoptotic changes and cytoplasmic vacuoles |
Increased mechanical resistance of the ALC |
