Abstract

An 83-year-old woman with a long history of glaucoma and optic disc drusen (ODD) was referred for neuro-ophthalmological second opinion. The patient had been treated for decades with bilateral intraocular pressure (IOP)-lowering eye drops, laser trabeculoplasty and trabeculectomy and had severe, bilateral loss of visual fields and retinal nerve fibre layer (RNFL) thinning on optical coherence tomography (OCT) despite IOP that never exceeded 24 mm Hg. On ophthalmoscopy, only a single ODD was visible in the left eye and no optic disc cupping was apparent in either eye. Enhanced depth imaging OCT (EDI-OCT) of the optic nerve head revealed bilateral multiple, large, deep ODD, which in itself could easily explain the visual field loss and RNFL thinning of this patient. Optic nerve head examination using EDI-OCT is highly recommended for patients with a history of glaucoma but without optic nerve head cupping to avoid a potential misdiagnosis with consequent unnecessary treatment.
