This 88YO female developed kissing choroidal detachments immediately following Ahmed glaucoma valve placement.
The choroidal detachment spontaneously resolved after 1 month once the intraocular pressure normalized.
Learning Points:
Choroidal detachment is relatively common immediately following glaucoma surgery.
Two mechanisms are believed to be at play: hypotony allows fluid to accumulate in the suprachoroidal space and inflammation increases the choroidal permeability. The detached ciliary body may also produce less aqueous, thus creating a self-perpetuating cycle.
Often, observation is sufficient, but topical steroids and cycloplegics can be helpful to aid in resolution.
