Glaucoma is an eye disease resultingin the loss of eyesight due to fluidaccumulation inside the eyeballwhich in turn builds-up pressureover the optic nerve, eventuallyleading to blindness.
A new drug developed by theUS-based Pharmacia Upjohn Incorporated, latanoprost, is more effective than the standard drug for glaucoma,timolol. The latter is known tohave numerous side-effects rangingfrom respiratory problems to irregular heartbeats also, people withhearing or respiratory problemscannot use it. Latanoprost, significantly, has fewer side-effects. Butwhat worries scientists is the unfamiliar transformation of blue andgreen eyes to the colour brown withthe use of latanoprost.
