Right Homonymous Hemianopia: A Clinical Case Report of Schizencephaly

PURPOSE: To report a case of a 56-year-old male with right homonymous hemianopia. METHODS: Retrospective descriptive study of a case report based on information from clinical records, patient observation and analysis of complementary diagnostic tests. RESULTS: An asymptomatic 56-year-old male presen...

description PURPOSE: To report a case of a 56-year-old male with right homonymous hemianopia. METHODS: Retrospective descriptive study of a case report based on information from clinical records, patient observation and analysis of complementary diagnostic tests. RESULTS: An asymptomatic 56-year-old male presented to our hospital for a routine ophthalmic examination. The best-corrected visual acuity was 20/20 in the right eye (RE) and in the left eye (LE). Pupillary function, intraocular pressure, external segment examinations and slit-lamp biomicroscopy were normal, bilaterally. Fundoscopy showed a cup-to-disc (C/D) ratio in the RE of 0.3 and of 0.4 in the LE. Retinal nerve fiber layer (RNFL) thickness measured by spectral domain optical coherence tomography revealed thinning of the superior, temporal and nasal RNFL in the RE and thinning of the superior, inferior and temporal RNFL in the LE. Automated static perimetry showed right homonymous hemianopia. Brain computed tomography (CT) showed an open-lip schizencephaly with a significant reduction of the left brain parenchyma. CONCLUSIONS: Despite the large visual defect, the patient was unaware of it and had an active professional life. This is an interesting case because despite the extensive morphological abnormalities seen on brain CT there is a relatively small functional repercussion.
