Gait Implications of Visual Field Damage from Glaucoma.

Glaucoma severity was associated with several gait parameters predictive of higher fall risk in prior studies, particularly measures of stride-to-stride variability.

Predicting Visual Disability in Glaucoma With Combinations of Vision Measures.

Vision in glaucoma is a multidimensional construct that can be described by several variably-correlated vision measures. Measuring more than two vision tests does not substantially improve models for activity limitation.

Predictors of Falls per Step and Falls per Year At and Away From Home in Glaucoma.

In this glaucoma population, most falls occurred at home, and the risk of any step resulting in a fall was higher at home.

Locations, Circumstances, and Outcomes of Falls in Patients With Glaucoma.

Glaucoma patients fall mostly in/around the home and demonstrate similar fall circumstances across the spectrum of disease severity, suggesting that current fall prevention interventions, particularly those emphasizing home modification, may be an adequate starting point…

Gait and Balance as Predictors and/or Mediators of Falls in Glaucoma.

Although balance and gait measures are associated with fall rates, they do not explain why persons with greater visual field damage fall more frequently, suggesting the importance of other potential factors such as hazard perception.

Vision Parameters Most Important to Functionality in Glaucoma.

Measures of visual ability are important for several aspects of quality of life and functionality.

Quantifying Fall-Related Hazards in the Homes of Persons with Glaucoma.

Multiple home fall hazards were identified in the study population, and hazard numbers were not lower for persons with worse VF damage, suggesting that individuals with more advanced glaucoma do not adapt their homes for safety.

Patterns of Daily Physical Activity across the Spectrum of Visual Field Damage in Glaucoma Patients.

At worse levels of VF damage, glaucoma patients demonstrate shorter, more fragmented bouts of physical activity throughout the day and lower activity levels during typical waking hours, reflecting low physiologic functioning.

Association Between Visual Field Damage and Gait Dysfunction in Patients With Glaucoma.

At worse levels of baseline VF damage, patients with glaucoma in this study demonstrated an exacerbated decline in walking speeds (ie, stride velocity and cadence), indicating that mobility speeds decrease faster over time in older…

Impact of the Ability to Divide Attention on Reading Performance in Glaucoma.

Decreased ability to divide attention, indicated by lower BTA scores, is associated with slower reading speeds in glaucoma with reduced CS and VF defects.

Assessing Functional Disability in Glaucoma: The Relative Importance of Central Versus Far Peripheral Visual Fields.

The relative importance of central 24 degrees versus more peripheral VF damage differs across functional domains in patients with glaucoma.

Referral to Low Vision Services for Glaucoma Patients: Referral Criteria and Barriers.

Among glaucoma specialists, patient-reported difficulties with vision-related activities were the most common criteria used for LVS referral.

Referral to Low Vision Services for Glaucoma Patients: Referral Patterns and Characteristics of Those Who Refer.

Familiarity with PPP guidelines may positively influence LVS referral practices.

Environmental Features Contributing to Falls in Persons With Vision Impairment: The Role of Home Lighting and Home Hazards.

Fewer home falls were found with better lighting, but not with fewer home hazards. Lighting improvements at home may reduce fall rates in older adults.

Importance and Severity Dependence of Physical Activity by GPS-Tracked Location in Glaucoma Patients.

Restriction of physical activity in more patients with severe glaucoma results mostly from activity restriction outside the home environment.

The Impact of Neighborhood Factors on Physical Activity in Older Adults With Visual Impairment.

Select NFs (poverty share and crime rate) may disproportionately affect physical activity in patients with severe VF loss.

Low-Vision Services and the Glaucoma Patient.

Association of Optic Nerve Head and Macular Optical Coherence Tomography Measures With Glaucoma-Related Disability.

OCT RNFL, but not GCIPL, thickness is associated with multiple disability measures independent of VF damage severity.

Relationship Between Intraocular Pressure and Age: A Population-Based Study in Nepal.

Mean IOP was lower among older individuals in Nepal, consistent with many studies from East Asia and in contrast to many studies from western populations.

Author Response: Comments on Evaluation of Central and Peripheral Visual Field Concordance in Glaucoma.

Evaluation of Central and Peripheral Visual Field Concordance in Glaucoma.

Central 24-2 testing generally reflects the extent of damage to the more peripheral VF in glaucoma, although significant disagreement exists for individual eyes.
