Abducens palsy childhood benign recurrent, also known as benign recurrent abducens nerve palsy or recurrent sixth nerve palsy, is a relatively uncommon condition that affects children. It refers to the recurrent episodes of paralysis or weakness of the abducens nerve (cranial nerve VI) that innervates the lateral rectus muscle responsible for outward eye movement.
This condition typically presents with sudden onset episodes of eye misalignment, with the affected eye unable to abduct properly, leading to a crossed or inward gaze (esotropia). The episodes can last for a few hours up to days and may recur multiple times throughout childhood, with periods of complete resolution in between.
The cause of abducens palsy childhood benign recurrent is unknown, but it is believed to be related to a temporary dysfunction or inflammation of the abducens nerve. It may occur spontaneously or be triggered by factors such as viral infections or minor head trauma.
Diagnosis of this condition is based on clinical evaluation, ruling out other causes of eye misalignment, and confirming normal eye movements during periods of resolution. Neuroimaging studies are typically not required.
Treatment for abducens palsy childhood benign recurrent involves addressing the symptoms and providing supportive care during episodes. Most children spontaneously recover within a few days to weeks without any long-term complications. In some cases, patching the unaffected eye or using prism eyeglasses may be recommended to alleviate diplopia (double vision) during episodes.
Regular follow-up with an ophthalmologist is important to monitor the progression of the condition and ensure appropriate management.
