Phacolysis tends to be more frequently reported in underdeveloped countries because of the lack of resources necessary to treat such as condition. There are a variety of characteristics which indicate that an individual may have phacolytic glaucoma. Within older people, the lens of the eye may appear to be yellow and lose its transparency (becomes cloudy). Once the protein begins to seep into the lens, permanent damage to the lens may be caused as the precipitate in lens impairs vision. Another symptom includes the fading of visual
Glaucoma valve drainage, such as iStent, CyPass, or Hydrus. A Cochrane Review of various aqueous shunts and modifications found that the Baerveldt implant may result in lower IOP than the Ahmed implant, but it was unclear if the difference in IOP reduction was clinically significant. The review suggests that practitioners should operate with the devices that they are most comfortable with, and have the most experience using. The glaucoma valve implant is indicated for glaucoma patients not responding to maximal medical therapy, with previous failed guarded filtering surgery (trabeculectomy) or in cases where conventional drainage surgery is unlikely to succeed.
