Eye drops are used, depending on the variety and the type of eye, to assist with a variety of ocular ailments. Perhaps ten or twelve years ago it somehow came to be that my intraocular pressure had to have been measured and was found to be just ever so slightly higher than normal. I was prescribed Xalatan and used it consistently over the span of about four years throughout which annually I would have additional eye pressure tests. With each subsequent test I decreased the Xalatan until eventually I just stopped. Six months after having completely stopped I went for what ended up being my last eye pressure test and it came out normal. Perhaps the initial reading was flawed? Who knows.
