Clinical Manifestations and Oculomotor Abnormalities in Congenital Esotropia

Lee, Young Chun

Abstract

Congenital esotropia, which shows various clinical signs and oculomotor abnormalities is a manifest inward deviation with onset between birth and 6 months of age.Author prospectively evaluated the frequency of clinical signs and oculomotor abnormalities in 18 patients [male:10, female:8]with congenital esotropia. Age distribution of patients is ranging 7 months to 16 years of age.Onset between 2 and 4 months of age were reported in 11[61%]out of 18 patients.Thirteen patients had predominant eye, and 4 patients showed cross fixation.Five out of 18 patients showed normal visual acuity, 4 patients showed decreased visual acuity of both eyes and 9 patients showed amblyopia in one eye.Head turning or tilting was found in 13 patients[72%]. Inferior oblique overaction more than 2 at least in one eye and dissociated vertical deviation were found in 9[50%] and 7 patients[39%]respectively.The frequency of oculomotor abnormalities, pursuit asymmetry and latent fixation nystagmus was 83%[15 out of 18 patients]and 72%[13 out of 18 patients]respectively, and both of pursuit asymmetry and latent fixation nystagmus were observed in 12 patients[67%]. High frequency of oculomotor abnormalities in congenital esotropia suggest an importance of not only examination of clinical symptoms but also examination of oculomotor abnormalities.
