This case report details the presentation, diagnosis, and management of an 88-year-old female with vision loss, highlighting the ocular manifestations of presumed VAD. Despite vitamin A levels being at the lower end of the normal range, the patient’s symptoms and spectral domain optical coherence tomography (SD-OCT) findings suggested insufficient levels, leading to thinning of the outer nuclear layer. This case underscores the necessity of considering VAD in differential diagnoses of unexplained vision impairment, particularly in individuals with a history of intestinal malabsorption, while also emphasizing the importance of distinguishing VAD from AMD in elderly patients.Keywords: vitamin A deficiency, malabsorption syndrome, age-related macular degeneration
