Study Reveals Patient Perception of Visual Field Loss in Glaucoma

Investigators in a recent study asked open-ended interview questions of 50 glaucoma patients, with a range of visual field defects in both eyes.

The patients described in their own words their visual field loss and selected one of six images that most closely represented their perception of their visual field loss.

It was reported that patients with glaucoma do not perceive their vision loss as a black “tunnel effect” or as “black patches” masking their view. Instead, they associate their visual symptoms with words such as “blur” or “missing.”

Twenty-six percent of patients said they were completely unaware of their vision loss.
