Acute acquired concomitant esotropia with congenital paralytic strabismus: A case report

Abstract

BACKGROUND

An unusual case of acute acquired concomitant esotropia (AACE) with congenital paralytic strabismus in the right eye is reported.

CASE SUMMARY

A 23-year-old woman presented with complaints of binocular diplopia and esotropia of the right eye lasting 4 years and head tilt to the left since 1 year after birth. The Bielschowsky head tilt test showed right hypertropia on a right head tilt. She did not report any other intracranial pathology. A diagnosis of AACE and right congenital paralytic strabismus was made. Then, she underwent medial rectus muscle recession and lateral rectus muscle resection combined with inferior oblique muscle myectomy in the right eye. One day after surgery, the patient reported that she had no diplopia at either distance or near fixation and was found to be orthophoric in the primary position; furthermore, her head posture immediately and markedly improved.

CONCLUSION

In future clinical work, in cases of AACE combined with other types of strabismus, we can perform conventional single surgery for both at the same time, and the two types of strabismus can be solved simultaneously.

Core Tip: Clinically, in cases of older children, adults, or even the elderly with sudden diplopia accompanied by simultaneous or subsequent esotropia, acute acquired concomitant esotropia (AACE) should be considered after excluding intracranial space-occupying lesions and vascular diseases. In recent years, the diagnosis and treatment of AACE have improved considerably, and until now no one has reported any case of AACE combined with other types of strabismus either in China or abroad. Here, we report one case of AACE with congenital paralytic strabismus.
