Abstract PURPOSE: To report the occurrence of mirror image congenital esotropia and concordant hypermetropia in a pair of monozygotic twins. METHODS: A pair of twins was recruited through the Australian Twin Registry. Zygosity was determined by questionnaire, physical appearance, and standard genotyping. Visual acuity was measured using the logMAR chart at 3 m followed by cycloplegic refraction using the Topcon autorefractor. RESULTS: Twin 1 developed right eye esotropia at 2 years of age with bilateral hypermetropia (right = +5.75 D, left = +5.75 D). Twin 2 developed left eye esotropia at age 2 years with bilateral hypermetropia (right = +6.75, left = +7.50). CONCLUSIONS: We describe the first reported case of mirror image congenital esotropia with concordant hypermetropia in monozygotic twins.
