This is why glaucoma is sometimes called the âsilent thief of sight.â. Vision loss from glaucoma can make things look blurry around the edges.

Both open-and closed-angle glaucoma can be secondary when caused by something known. Causes include: 1  Drugs such as corticosteroids. 2  Eye drops that dilate your eyes. 3  Eye diseases such as uveitis (an infection of the middle layer of the eye). 4  Diseases such as diabetes. 5  Eye injury.
