To compare face recognition performance of glaucomatous patients with age-similar visually healthy people.
Percentage of correctly identified faces in the Cambridge Face Memory Test was assessed in glaucomatous patients (n = 54; mean age = 69) with a range of visual field (VF) defects and visually healthy controls (n = 41; mean age = 67). All participants underwent cognitive and visual assessment (binocular visual acuity [BVA], contrast sensitivity [CS], and Humphrey VFs, both 10-2 and 24-2) and had BVA of at least 0.18 logMAR. Patients were classified as having “early,” “moderate,” or “advanced” VF defects using the Hodapp, Parrish and Anderson method. Patients were also stratified by better-eye 10-2 mean deviation (MD) being better or worse than the 1% normative value.
There were no significant differences in age (P = 0.25) or cognitive ability (P = 0.31) between groups; however, differences in BVA and CS were statistically significant (P < 0.05). Patients with advanced VF defects identified fewer faces on average (±SD) (66% ± 15%) than those with early (75% ± 11%) and moderate (75% ± 13%) defects and controls (75% ± 11%); P < 0.05. Patients with a best-eye 10-2 MD P < 1% identified fewer faces (67% ± 13%) than those with 10-2 MD P > 1% (77% ± 11%) and controls P < 0.01 (75% ± 11%). Multiple regression analysis revealed CS was important for face recognition.
When compared with age-similar people with healthy vision, glaucomatous patients with advanced bilateral 24-2 VF loss, significant 10-2 VF loss, or poor CS are more likely to experience problems with face recognition.
