Diplopia, commonly known as double vision, happens when the nerves that control your eye movement muscles become damaged. Normally, these eye movement muscles work together, but when double vision develops, a persons’ eyes may no longer work in tandem. When the images produced by each eye do not match, the brain misinterprets the information as two misaligned objects.
Occasionally double vision may only occur when someone is looking in specific directions, for example, all the way to the side, or straight ahead. It may also be aggravated by fatigueOverview The brain plays a crucial role in regulating sleep ... or time of day. Cranial nerve palsies are the most common cause of binocular diplopia (67%) with half of these being abducent nerve palsies.¹

¹To evaluate the causes and outcomes for patients presenting with diplopia to an eye casualty department. Patients presenting with diplopia as a principal symptom, who were referred to the Orthoptic Department from Moorfields Eye Casualty over a 12-month period, were retrospectively investigated. One hundred and seventy-one patients were identified with complete records in 165 cases. There were 99 men and 66 women with an age range of 5-88 years. Monocular diplopia accounted for 19 cases (11.5%), whereas 146 patients (88.5%) had binocular diplopia. Cranial nerve palsies were the most common cause of binocular diplopia accounting for 98 (67%) of cases. Isolated sixth nerve palsy was the largest diagnostic group (n=45). Microvascular disease (hypertension or diabetes mellitus, or both) was present in 59% of patients with cranial nerve palsies, and of this group, 87% resolved spontaneously by 5 months rising to 95% by 12 months. Patients with clinically isolated single cranial nerve palsies associated with diabetes or hypertension are likely to recover spontaneously within 5 months and initially require observation only. However, patients with unexplained binocular diplopia and those who progress or fail to recover should be investigated to establish the underlying etiology and managed as appropriate.
