Traumatic cataract presenting with unilateral nasal hemianopsia

Binasal visual field defects caused by temporal posterior subcapsular cataracts

A 55-year-old female presented with binasal visual field defects and normal neuro-ophthalmic examination. Slit-lamp examination demonstrated posterior subcapsular cataracts that were located temporally in the visual axis. Due to the location of the nodal point in the eye, her visual field defect was contralateral to the opacity. Her visual field defects resolved after cataract surgery.

Monocular nasal hemianopia from atypical sphenoid wing meningioma

Neurogenic monocular nasal field defects respecting the vertical midline are quite uncommon. We report a case of a unilateral nasal hemianopia that was caused by compression of the left optic nerve by a sphenoid wing meningioma. Histological examination revealed that the pathology of the meningioma was consistent with that of an atypical meningioma, which carries a guarded prognosis with increased chance of recurrence. The tumor was debulked surgically, and the patient's visual field defect improved.
