Exercise induced esotropia

Exercise-induced diplopia: a mysterious and rare entity

A rare case of idiopathic exercise-induced diplopia was reported. A 28-year-old male experienced diplopia during and after intensive exercise. These symptoms had been present for over a year. Upon first examination, orthophoria was found. Upon examination after intensive exercise, an esophoria of 10^∆ at near and an esotropia of 4^∆ at distance was found. Neuroimaging and neurological, cardiological, and hematological evaluations were normal. A prism correction, to be used during exercise, partially resolved the diplopia. This case report aims to highlight and create general awareness about exercise-induced diplopia.

A Case Series: Exercise-Induced Esotropia

The authors present three patients with idiopathic exercise-induced esotropia. The history, physical findings, and testing that led to the diagnosis are discussed. To the authors' knowledge, this is the largest series of patients with this rare condition, with this series representing half of reported patients in the literature. It is hoped that a discussion of common features of the condition will guide further exploration of the etiology.

Surgical management of a patient with exercise-induced esotropia

Exercise-induced esotropia is a rare form of strabismus characterized by paroxysms of esotropia and diplopia only during exercise. This report describes a 15-year-old boy who presented with a 1-year history of exercise-induced esotropia. He has been asymptomatic after recession of a single medial rectus muscle. It is hypothesized that the esotropia was attributable to a malfunction in the muscle tension-control circuit and that altering the small signal gain with surgery resulted in improvement.

Exercise-induced esotropia

The authors evaluated a 34-year-old man with exercise-induced diplopia. The diagnostic testing that led to this conclusion is discussed. To the authors' knowledge, this is a rarely reported condition that warrants discussion.
