Diplopia: a diagnostic challenge with common and rare etiologies.

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.
