Glaucoma Glaucoma Glaucoma is a group of eye diseases which result in damage to the optic nerve and vision loss. The most common type is open-angle glaucoma with less common types including closed-angle glaucoma and normal-tension glaucoma. Open-angle glaucoma develops slowly over time and there is no pain. Peripheral vision may begin to decrease followed by central vision resulting in blindness if not treated. Closed-angle glaucoma can present gradually or suddenly. The sudden presentation may involve severe eye pain, blurred vision, mid-dilated pupil, redness of the eye, and nausea. Vision loss from glaucoma, once it has occurred, is permanent. Risk factors
Hospital-acquired condition Hospital-acquired condition A hospital-acquired condition (HAC) is an undesirable situation or condition that affects a patient and that arose during a stay in a hospital or medical facility. It is a designation used by Medicare/Medicaid in the US for determining MS-DRG reimbursement beginning with version 26 (October 1, 2008). Not only hospital-acquired infections but also any other situation or condition, such as pressure ulcers, blood type mismatch, or iatrogenic injury, can be a HAC. A patient at a hospital can be infected or otherwise degraded by hospital conditions and/or personnel in ways that are sometimes diagnosed as a "complication." The
