Symptoms begin slowly and include vision loss and irregularities, eye pain, headache, nausea, and vomiting. Beta-blockers, Alpha-adrenergic agonists, and prostaglandin analogs are drugs used to treat glaucoma. Sometimes surgery is necessary, especially with congenital glaucoma. The disease is not curable but can be managed. -
