Glaucoma patients do not perceive visual loss as a black tunnel

(February 15, 2013 - Insidermedicine)

From London - A new report published in Ophthalmology examines how vision loss is perceived by glaucoma patients. Researchers studied 50 glaucoma patients, aged 52-82, with a wide range of visual field defects in both eyes. Participants underwent visual field testing, and were also shown several pictures and asked to select the image the best represented their perception of vision loss. None of the patients selected an image with a 'black tunnel' effect, or black patches. Rather, over 50% of the patients picked an imaged with blurred patches.
