Background. The corpus callosum is a primary commissural part of the brain which connects the two hemispheres. Processing sensory, motor, visuo-motor and cognitive functions are related to a healthy connection. In this study, we aimed to evaluate the ocular, neurologic and other systemic findings of corpus callosum malformations and to focus on the association between the ocular and neurological findings and the type of callosal malformation according to cranial magnetic resonance imaging (MRI). Methods. A retrospective chart review of 57 patients with corpus callosum malformation was performed. Demographic features, neurologic, ocular and other systemic findings were noted. Patients were divided into 3 groups according to the severity of corpus callosum malformation on MRI (total agenesis, partial agenesis and hypoplasia) and also evaluated as a part of a genetic disorder/syndrome or not. The differences between demographic features, ocular and neurological findings between these 3 groups and also between syndromic and non-syndromic groups were evaluated statistically. Results. Only 35.1% of patients had fixation and following pattern of visual acuity. Anterior segment pathologies were observed in 6.9% of patients. However, 57.9% of patients had posterior segment malformations. Only 19.3% of patients had a normal ocular alignment. There was no statistically significant difference of demographic features, ocular and neurologic findings between the 3 groups or between the syndromic/non-syndromic groups. Conclusions. Ocular findings can be reliable depending on the severity of the corpus callosum malformations. However, delay in fixation reflex development or loss of fixation should remind us of central nervous system pathologies especially corpus callosum malformations
