Causes and risk factors
Surgical correction of congenital esotropia is the commonest cause of monofixation syndrome. Other known causes are macular lesions and anisometropia.
Clinical presentation
The patient with monofixation syndrome does not experience any symptoms.
It is diagnosed clinically on the basis of subnormal stereovision and presence of asymmetry in best corrected vision. Monofixation syndrome commonly occurs in children.
Investigations
Monofixation syndrome is diagnosed with the help of several eye tests such as stereoacuity tests, prism test, and Bagolini lenses.
Treatment
Patients with monofixation syndrome as a result of previous surgery do not require any further correction. However, those with no history of previous surgery are recommended to undergo surgery for strabismus.
