Aim: To present a case of Alzheimer’s disease with poor vision which were not due to the ocular pathology.
Case report: A 74 years old male surgeon presented with a one year history of progressive, painless visual loss of one year duration and was found to have visually insignificant cataract, normal optic discs and mild pigmentary changes in the macular region. He was a known case of Alzheimer’s disease. Further evaluation revealed difficulties with comprehension, inability to recognize even members of his immediate family, his children and occasionally, his wife. He is unable to move around unaided and frequently bumps into objects. He frequently accuses people in the television of being intruders in his house. He is also frequently disoriented with difficulty describing what he had seen, difficulty reaching out to objects which he frequently knocks over. He experiences difficulties climbing and descending from stairs.
Conclusion: Elderly patients with dementia may present with poor vision not due to their ocular pathology but due to the neurological disorder. An index of suspicion is required to avoid needless surgery or other treatment.
