Gonioscopy in primary angle closure glaucoma
Bruno CA; Alward WLMSeminars in Ophthalmology 2002; 17: 59-68
Primary angle closure is a condition characterized by obstruction to aqueous humor outflow by the peripheral iris, and results in changes in the iridocorneal angle that are visible through gonioscopic examination. However, gonioscopy in these eyes can be difficult. This chapter discusses techniques that might help in the examination. These include beginning the examination with the inferior angle, methods to help in looking over the iris, cycloplegia, locating the corneal wedge, indentation, Van Herick estimation, examining the other eye, and topical glycerin. Finally, there is a discussion about the pathology associated with the closed angle, with emphasis on the appearance of iris bombe, plateau iris, and the distinction between iris processes and peripheral anterior synechiae.
