Correlation between visual function and an objective evaluation of the ability of glaucomatous patients to perform daily living activities

Abstract

Purpose : To analyze the correlations between functional clinical tests and objective tests evaluating daily living activities in glaucoma patients using artificial platforms (StreetLab® and Homelab®).

Methods : Thirty-two patients with chronic glaucoma, followed at the Quinze-Vingts National Ophthalmology Hospital, were included. All patients had a clinical evaluation of visual function including, best-corrected visual acuity (BCVA), contrast sensitivity (CS), and monocular and binocular visual field tests. Two standardized artificial platforms were used to evaluate activities of daily living (StreetLab® HomeLab®). Four different activities were evaluated: locomotion and obstacle avoidance in an artificial street, object detection, face recognition and eye-hand coordination. Patients performance in the different tasks were correlated to visual function evaluation including BCVA and visual field mean deviation (MD) of the better and the worst eye, Esterman binocular visual field (VF) and an integrated binocular visual field score (IVF).

Results : The Esterman score was significantly correlated to the locomotion and obstacles avoidance (Spearman correlation: r = -0.48; p = 0.006), object detection (r= -0.47; p = 0.006), face recognition tasks (r =-0.46; p = 0.008) and eye-hand coordination with small objects (r= -0.36; p = 0.046). The MD of the better eye was significantly correlated to the object detection (r = - 0.44; p = 0.010), face recognition (r = -0.4; p = 0.020) and eye-hand coordination with big object (r = -0.50; p = 0.003). The IVF score was significantly correlated to the object detection (r = 0.51; p = 0.003), face recognition (r = 0.49; p = 0.004) and eye-hand coordination with small and big objects (r = 0.37, p = 0.036 and r = 0.50, p = 0.004 respectively).

Conclusions : Glaucoma patients’ ability to perform daily living activities could not be evaluated precisely with monocular visual field tests. The MD of the better eye and the IVF score appeared to better evaluate face recognition, eye-hand coordination, and object detection. For locomotion and obstacle avoidance, the Esterman VF seemed more useful.
