2+-ATPase activities were significantly decreased in the lens and
vitreous humour of the cyanide-fed rabbits (p< 0.05), while the
corneal enzyme was unaffected. Ophthalmoscopic examination of the
cyanide-exposed rabbits revealed adverse morphological changes,
including pale fundus, low retinal reflex and lenticular opacification.
The results suggest that cyanide-induced cataractogenesis may be a
consequence of disruption of vitreous humour and lenticular calcium
homeostasis
