Monocular Temporal Hemianopia Associated With Optic Nerve Hypoplasia

Arch Ophthalmol. 2005;123(8):1155. doi:10.1001/archopht.123.8.1155

A 15-year-old girl was found to have temporal hemianopia of the left eye. Her visual acuity was 20/20 OU and she had normal color discrimination bilaterally. Left afferent pupillary defect was present. Right-eye perimetry results were normal, but complete temporal hemianopia respecting vertical meridian was found on the left (Figure 1). The nasal half of the left optic nerve disc showed agenesis (Figure 2). Magnetic resonance imaging revealed absent septum pellucidum, consistent with de Morsier syndrome.1
