NEW YORK (Reuters Health) - Healthy men who use drugs to treat impotence may be able to stop worrying - at least for now -- about a loss of vision caused by the drugs. A new study, published in the Archives of Ophthalmology, detected no changes in visual function, signs of retina damage or intraocular pressure after the daily use for 6 months of sildenafil (Viagra) or tadalafil (Cialis).
