Towards Expert Consensus on Diagnosing Higher Order Visual Dysfunction in Patients with Preexisting Ophthalmic Disease

Age-related eye disease commonly causes low vision, which can impede diagnosis of neurodegenerative disease causing visual processing dysfunction. Diagnosis of neurodegenerative disease in the setting of low vision is clinically important to guide comprehensive management for both low vision and dementia. Barriers to recognition of co-existing eye disease and visual processing dysfunction include attribution of visual symptoms to ophthalmic disease and lack of sufficient vision to complete standard visual processing tests. There is a need for consensus strategies for visual processing dysfunction detection in people with low vision due to ophthalmic disease.
