A Case of Neovascular Glaucoma Caused by Carotid Stenosis

Neovascular glaucoma (NVG) occurs when new fibrovascular tissues proliferate onto the chamber angle and obstruct the trabecular meshwork. We report a 62-year-old man who presented with progressive monocular visual loss that supervened on NVG. MR angiography and duplex sonography indicated stenosis of the right proximal internal carotid artery (ICA). A carotid endarterectomy was performed. But visual acuity was not improved. We suggest that early detection of NVG is critical for the prevention of visual loss and that rubeosis iridis and chemosis may be the clue to the presence of underlying carotid stenosis.
