Background: Diplopia is a symptom with very different etiologies. It may be caused by pathology in the eye, orbit, extraocular muscles, neuromuscular junction, or in the central nervous system.
Case Report: Three clinical cases of hospitalization due to isolated diplopia are presented here, illustrating different etiologies.
Conclusions: The present article aims to address the differential diagnosis of this clinical condition and to warn of less frequent causes of diplopia, such as adverse effects of commonly used drugs.
