84. Cataract – Sorbitol.. Polyol..osmotic.. Lens epithelium (Insulin independent) is exposed to Hyperglycaemia, excessive flux of glucose to sorbitol by the polyol pathway. The accumulation of intracellular sorbitol exerts osmoprotection and prevents cell shrinkage. The excessive accumulation of sorbitol, causes an increased osmotic load within the lens causing swelling, fibre breakdown, and opacification (the osmotic hypothesis). Other mechanisms, including glycation and oxidative stress, may also be responsible for lens opacification.
