PURPOSE: To describe a case of successful resolution of severe hypotony and choroidal detachments following non-filtering glaucoma surgery with an intravitreal injection of C3F8 gas after a poor response to topical steroids and cycloplegia. METHODS: Retrospective chart review of a case report. PATIENT: 89 year-old male. RESULTS: Patient presented with a central retinal vein occlusion, hyphema, vitreous hemorrhage and neovascular glaucoma. After initial intravitreal injection of aflibercept he was treated with pars plana vitrectomy with panretinal photocoagulation and endocyclophotocoagulation to the ciliary body, but he continued to have elevated intraocular pressure. Subsequent external cyclophotocoagulation was performed but severe hypotony with inflammation, choroidal detachments, and corneal edema developed one week later without response to cycloplegic and steroid medications. A therapeutic injection of perfluorpropane (C3F8) gas led to resolution of the hypotony and choroid detachment and long-term maintenance of intraocular pressure.Discussion/ CONCLUSION: An intravitreal gas bubble can be a very useful outpatient procedure to immediately reverse hypotony, resolve choroidal detachment, and decrease associated inflammation. When hypotony does not respond to medical therapy with cycloplegic drops and steroid medications, then an intravitreal gas bubble can rapidly resolve these complications and result in stabilization of intraocular pressure long term.
