Spontaneous Improvement of Essential Infantile Esotropia;A Case Report

To present a case of spontaneous resolution of essential esotropiaCase Report: A 22-month-old girl presented with eye deviation since the age of 4 month. In the first examination, visual acuity of both eyes was C+S+M+. The patient had 35 prism diopters of alternative esotropia in primary position and also bilateral inferior oblique overaction (IOOA). There was no significant refractive error and other ophthalmic and systemic evaluations were normal. In follow up examinations the amount of esodeviation decreased gradually and at the last examination (at the age of 4 years) the patient was orthotropic in primary position in spite of residual bilateral IOOA. The amount of deviaton in patient with essential esotropia usually seems to be stable; however spontaneous resolution of esodeviation is possible, however IOOA, dissociated vertical deviation or latent nystagmus may remain.
