This is an error. If your eyes or lids turn red, itch, or swell, you should call your eye care specialist immediately. Eye drops should always be used according to the schedule given to you. Drops are powerful medications, not just a clear watery liquid. An increased pressure inside the eye, which injures the internal nerve tissue, causes glaucoma.
Some medications diminish the formation of the liquid inside the eye while others increase drainage.
Your eye care specialist will try to obtain adequate control of your eye pressure with the least inconvenience or side effects. Glaucoma patients should adhere strictly to their medication schedule. These eye-drops lower the pressure in glaucomatous eyes. When the pressure is low and under control, vision loss usually stops. When the pressure is higher, unrecoverable vision loss may occur.
