Placement of an Ahmed valve with the drainage tube in the anterior chamber in an eye with unconrolled neovascular glaucoma

 

This 81 year old man has been managed for 3 months with laser, drops and oral medications for neovascular glaucoma induced by a central retinal vein occlusion.  His intraocular pressure is between 30 and 40 despite maximal medical therapy.  He also has a history of heart failure.  Some of his glaucoma medications cannot be continued without risk of exacerbating his heart disease.  His visual acuity is 20/160 in this eye.  His other eye is 20/60 because of a macular pucker.
