Activity limitations are the difficulties in executing vision-related tasks as a result of impairment, such as inability to cross the road because of glaucomatous visual field loss. The Glaucoma Quality questionnaiire Life Questionnaire correlated well with objective measures of visual function and discriminated between quality of life in patients with glaucoma and subjects without glaucoma.

For example they may be related to near vision correction rather than to glaucoma; hence, these items do not behave predictably across the whole population. Patients were 18 years of age or older, spoke German, and had no cognitive impairment.

Visual field defects were classified into mild, moderate, and severe visual field loss using mean deviation MD indices and a modification of the Hodapp—Parrish—Anderson classification 27 in the more severely affected eye.
