Acute acquired comitant esotropia in adults: Is it neurologic or not?

Objectives. acute acquired comitant esotropia (aace) can be a diagnostic challenge for ophthalmologists and neurologists because of its association with neurological pathologies. our study describes a series of adult patients with aace of undetermined etiology. methods. data on the clinical findings of patients presented with aace of undetermined etiology with a minimum follow-up of 1 year were retrieved from the medical records and the results analyzed. results. a series of 9 esotropia cases (age range: 20-43 years) was reviewed. all patients had full duction and versions,without an a-pattern or v-pattern. all patients had esotropia for distance and near. neurological evaluation in all cases was normal. among patients,3 were treated with prisms,4 were treated with strabismus surgery,and 1 was treated with botulinum toxin injections; 1 patient declined treatment. in treated patients posttreatment sensory testing indicated restoration of binocularity that remained stable throughout follow-up of 1-9 years. the patient that declined treatment had binocular function with base-out prisms. conclusion. acute onset esotropia may be seen without a neurological pathology in adults. good motor and sensory outcomes can be achieved in these patients with aace of undetermined etiology via surgical and nonsurgical methods. © 2016 kadriye erkan turan and tulay kansu.
