phenothiazinescataractslarge study‚ąístrong association
allopurinolcataractsrisk independent of diabetes in one study but significant factor in another
cidofoviriritis + hypotonyiritis more likely in diabetes
scopolamineacute angle glaucomapredictable from transdermal patch
steroids (oral)open angle glaucoma and ocular hypertensionlarge study confirmed increased risk
steroids (oral)cataractsincreased risk
steroids (eye drops) cataractssmall study but significant risk
steroids (inhaled)cataractsincreased risk
