Acanthamoeba Keratitis Secondary Glaucoma Associated With Mature Cataract and a Fixed Dilated Pupil in a 40-Eye Series

Mature cataract or a fixed dilated pupil has not been previously identified as a cause of secondary glaucoma in AK. The implications are that both result in angle closure and that early surgery for maturing cataract, despite its complexity, might prevent the development of angle closure. However, the potential for better medical treatment to reduce the time to cure to less than 12 months is likely the most effective way to reduce AK glaucoma incidence. Successful management of AK glaucoma once developed probably requires use of a glaucoma drainage device.
