Visual field loss and gain comparable at 5 years in open-angle glaucoma patients

Rates of visual field loss and gain are comparable 5 years after baseline treatment in patients with open-angle glaucoma, according to an evaluation of the Collaborative Initial Glaucoma Treatment Study.Study authors compared visual field gains and losses in patients who underwent treatment for open-angle glaucoma with either trabeculectomy or topical medications. Although the study emphasized that rates of improvement and loss were comparable during early follow-up, upon continued follow-up after 5 years, visual field loss became more predominant.
